Using a top-notch laser level could mean the difference between excellent construction work or a sloppy end product. The most accurate laser level would be the obvious choice if you are after dead center, dead level construction accuracy.
But that doesn’t mean it’s the best laser level, depending on your building needs, you might want to invest in a small laser level or a more industrial outdoor laser level.
Regardless of the size of your project, whether it’s a DIY project, big or small, it shouldn’t be taken on without the best self-leveling laser possible. Nothing is more frustrating when measurements don’t line up, and your left admiring your project that’s askew or worse, not fitting together at all.
You might only have a small job right now, i.e., refitting some guttering, so you might be tempted to pick up the best cheap laser level. However, I advise you to shop around a bit and invest in the long term and pick up a professional level as from my experience, once you have one, it’ll get used often.
Hopefully, in these unbiased laser level reviews, I’ll guide you to purchasing the best laser level for the money but also your needs.

Types of Laser Levels
A line laser will project a straight line from one point to another, usually over a distance for 64-100 feet. Depending on the model, you can project multiple lines, allowing you to check for straightness and squareness.
Line lasers are usually very compact and can be mounted onto ladders, or even a regular camera tripod.
most line lasers are built for indoor use as they can be challenging to see in bright light, but newer models are equipped with better LED diodes that can be seen outdoors, green diodes tackle this very well,
Some also have a pulsating light technology that can be used with a laser detector for outdoor use.
Dot Lasers / Plumb lasers
As its name implies, the way this type of laser level works is by projecting single or multiple reference dots on the work surface. It works the same way a water level or plumb bob works, only much more accurate for longer distances.
The main problem with dot lasers is they tend to have shorter ranges versus the other types of laser levels; as such, they can be challenging to use for any other purpose other than as a reference point.
Rotary laser levels project a level line, very similar to a line laser, but this line rotates around a room in a 360-degree fashion. There’s usually both a single line generator and also a plumb up and plumb down capabilities in these.
Model models are remote-controlled for convenience. Rotary lasers are highly accurate and are ideal for outdoor work, such as laying foundations, pipes, and even grading roads.
While a rotary model is more powerful than a line laser, it’s also much bulkier and usually more costly.
You will need to use a sturdy base if you want to mount a rotary laser because they are bigger than a line laser. These are designed for foundation work so they can be substantial and must be mounted onto a platform or tractor.
Laser Level Buying Guide
Many different factors separate the best laser levels from the waste of money variety. Here are some things to look for.
The majority of laser levels these days offer two types of accuracy levels. Self-leveling and preset (or manual). I suggest you aim for a self-leveling version for the simple reason as they automatically find their true level, it saves you time and hassle.
They have an inner pendulum, which lets the level find it’s best accuracy.
However, while I think that self-leveling models are the best, they do tend to be more expensive, so if you are looking to save a bit of money, there is no harm in getting a preset manual version. If you do, make sure you get one that has an accuracy ratio of at least +-3Xm.
Ask a bunch of professionals or a bunch of hobbyists, and each group will give you different answers, not just at a group level but at an individual level. Some will vouch for red beams others for the green beam laser, so which should you go for?
Both of these color beams have their advantages and disadvantages.
- Red beams, for instance, will consume less power and are fantastic for all indoor tasks, but can suffer against bright sunlight.
- Green beams, on the other hand, provide up to 300 times more power, so they are ideal for working outdoors and in direct sunlight
So, if you will be working indoors, then a red beam laser is perfect for you if however, you are going to be doing work in direct sunlight whether indoors or outside, then green beams are a better option.
When looking at laser levels, you need to factor in how long the batteries will last. These are a running cost at the end of the day, so if you are chewing through batteries, it’s going to cost you in the long run.
So check for runtime, life cycle, Amp-hour rating, and voltage.
Runtime – as you might have guessed, is how long the batteries will last, some models offer up to 30 hours of runtime.
Life cycle – is about how many times the batteries can be recharged before they won’t recharge anymore. The higher the life cycle, the more rechargeable the battery will be.
Amp-hour – rating determines how long the battery will last
Voltage – This determines the output (or power) of the laser. If your battery provides more volts, the brighter the laser will be.
Voltage may not affect the effective range of the tool.
Ease of Use
Each model is going to be operated differently, some will have one or two buttons, while others – which are usually more advanced – will require you to configure their settings for each use.
So you need to select the right model for you; I aim for ones with as few buttons as possible. It just makes life easy, and I don’t need complicated setup every time I start my laser level.
There are typically two types of lasers and which one you need depends on where you intend to use it.
If you are leveling a floor, then a horizontal laser will let you quickly locate the spots that aren’t level.
Dual-beam lasers, while being more expensive, offer two beams simultaneously, (cross beam lasers for example) these allow you to measure both horizontally and vertically at the same time. Fantastic for installing cabinetry.
A common feature these days is that your level will automatically find “level” when you turn it on. You can still get manual/present models. But self-leveling is the way to go.
Operating Temperature Range
Generating a laser creates heat, being out in the sun or a hot room adds to that heat, so you want to ensure that your laser level has a large operating temperature range so that it can work in hot and cold climates.
Multiple Mounting Threads
Need to mount your level indoors and outdoors? Then you may need multiple mounting threads. Why? So you can mount the laser onto different types of surfaces. Some give you the option to attach them to tripods.
High IP Rating
IP stands for Ingress Protection. An IP rating tells you the degree of protection the tool will have against dust and water. The higher the IP rating, the more durable the product is. If you are only going to use your laser level indoors, then the IP rating may be pointless.
Though I tend to look for an IP54 rating, as this means it can get wet and won’t stop working!
Remote Control Capability
Being able to control your level from a distance remotely is handy, especially if you are working alone. Being able to make micro-adjustments without having to run back and forth from the laser and the work surface, well for me, it’s a godsend.
Though do note that the remote controls have their working range. Even the best remote controls have a range that usually only half the tools maximum operating distance.
Power Level and Warning Indicator
knowing how much power you have in the batteries is a convenient feature, you don’t want to be in the middle of a task then suddenly for your laser to die.
Having something like three small lights located on the unit which tells you how much battery power is remaining is very useful.
As for a warning level, it’s something that will tell you that something is wrong with the product. Some models display an audible warning; others do nothing but shut down when things are amiss.
What is a laser level?
A laser level is a tool that started in the construction industry, though it’s now widespread and something that every household should have. It’s a tool that measures levelness by projecting either a red or green light beam onto a flat surface.
Laser levels are used to deduce how level or straight a surface is, by project a light beam across or around it. Very similar to how you would use a chalk line.
Small traditional laser levels are perfect for use in and around your home for DIY projects, while the bigger and more industrial versions are better suited for outdoor and construction job sites. Home DIY projects, even small ones such as hanging picture frames or laying down carpets, really benefit from incorporating a laser level.
A good quality laser level will reduce the amount of measuring you would need to do and takes away the guesswork of knowing whether a surface is level or not. I must point out these you should never point these are someone’s eyes; these are lasers and will cause damage. Most laser levels are manufactured with a low-intensity diode and are battery operated, giving you the freedom of movement without the worry of tripping over long extension cords. The type of level you need will depend on the size of the project you have on hand and whether it’s indoors or outdoors.
If your aim is to hang a few picture frames, then it wouldn’t make sense to purchase an expensive industrial, professional laser level. In the way that a large, bulky laser level doesn’t make sense for small DIY jobs around the home.
Laser levels can be self-leveling, and all that means is that they can detect whether or not the area in which they are standing is level, with the help of internal self-leveling sensors.
These lasers are incredibly time effective and accurate compared to their manually set counterparts.
Most level lasers can be divided into three categories, Plumb, line level, and rotary. Plumb lasers have a dot sight or a reference point, unlike line lasers, which will project a visual line or two cross lines onto a surface. Rotary lasers project a level line around the entire room and are usually bulkier.
How do laser levels work?
Laser levels work by using a laser beam to pinpoint the origin of levelness on a flat surface. A beam of light is emitted from the laser level through a device called a diode. The word “laser” is an acronym that stands for Light Amplification by the Stipulated Emission of Radiation. I’m sure you’ll agree that that’s quite a mouthful, simply put, it’s when electrons are stimulated to give off a beam of light, which is collected by mirrors or prisms and pointed in a particular direction. For us, the result is a laser beam.
Laser levels are used to project a solid line (though sometimes dots) onto a surface; this works just like a solid chalk line. Need a thicker line? The size of the diode sets the thickness of the line. A thinner project beam will be more accurate than a thicker beam, as the reference point is within the beam, so the small the beam, the closer to the reference point you are.
Laser levels are be used indoors and outdoors, and there was a time that these devices were limited to just indoor use because the laser beam itself was too weak to be seen outdoors in direct sunlight.
These days we have much more powerful lasers, which also come with the added benefit of audible level detectors, which give off a beeping sound one the level has been reached. You will find that most laser levels come with some sort of swivel attachment bracket on the tripod so you can keep the laser level steady. A lot these days also come with self-leveling capabilities, though some are operated manually.
Self-leveling lasers can detect whether they are level by using electronic sensors. In contrast, manual levels make use of a traditional bubble vial, and there’s nothing wrong with a water level!
Self-leveling lasers tend to be more accurate, but that comes at a cost, as the electronic extras will drain your battery power much fast than a manual laser level with a bubble vial.
How to Check Laser Level for Accuracy?
When you are taking on a project, it’s always better to measure twice and cut once… or so they say. A laser level is your best and more accurate option when it comes to measuring level, but it’s only accurate when it is level. So it’s worth taking some time to do some maintenance on your laser level and ensure that it is reading level.
The best time to do this is to check the accuracy of your laser level before you begin your project.
Even the best laser levels become less calibrated over time and need to be checked. I do this regularly. It only takes a few minutes as it is worth doing, so you don’t hang your pictures or curtains out of level. Trust me. It will save you embarrassment.
- Place your laser level on a tripod in the center of a large room, the exact position doesn’t matter, but it should be at least 20 ft from the walls of the room
- Turn your laser on and project a vertical level against the wall. Mark off the point where the laser hits the wall with a pencil
- Rotate the level by 180 degrees and mark that point with a pencil. Compare the two marks you made to see if the difference is within the general range or not.
- Rotate the level by 90 degrees and mark off against the wall. Rotate by 180 degrees, then recheck the difference. If the vertical beam is not within reach or if the axis fails to show the correct results, then you may need to calibrate your laser level.
Why Use a Laser Level?
Ever tried to hang a gallery of photos on a wall? Simple right? Just decide a layout, hammer in some nails and hand your picture frames, easy, right? As you’ll discover, if you do it that way, it really isn’t, your pictures won’t have where you want, and nothing will line up.
Look, picture this, you’re up a ladder, a hammer in one hand, a lever in another hand, and you want to hang a series of photos, and you want them all to be in a straight line.
The problem is, you can’t hold a level and hammer in a bunch of nails. Using a tape measure, you’ll be out by a millimeter here or there. Even if you pick up an electric hammer, you’ll soon realize you still need both hands.
So what do you do now?
You could use a chalk line, but that requires a second person or an additional hole in the wall. You could put two holes in your wall and run a nylon thread, but then you are adding unnecessary holes just to ensure your picture hooks are aligned.
If only you could hang your level on the wall without needing a nail to hold it up, hanging those pictures would be simple.
Well… there is a solution, a laser level, even a cheap laser will that you chunk into your toolbox will sort this out, it’ll project a laser beam across the wall that’s level, and you can just knock a nail onto the line where you want your photos to hang.
The result will be perfectly hung photos.
Laser levels are standard equipment these days in construction and the civil engineering industries.
You can use them to make cabinets, check the alignment of windows, doors skylights, dormers, spotlights, and concrete and asphalt work.
I’ve even used mine to ensure that plants where planted in a straight line!
If the experts are using these tools, why shouldn’t you?
Why Choose Laser Levels Instead Of Spirit Levels/Bubble Levels?
Look, there’s nothing wrong with using a spirit or bubble level. The truth is somethings; using these In DIY or construction jobs, using them is impossible.
Take the photo gallery example above, you could use a spirit/bubble level to create a guideline or where to put your holes, but you’d need experience, and you may end up with unnecessary holes in your wall.
Another problem is that they are only accurate for the length of the level and sometimes, no, most of the time when you are trying to level is either longer than your level or shorter than your level (i.e., a tight space fitting blinds into a recessed window), this means you either need a range of levels or you need to keep moving your level and finding level both vertically and horizontally.
What if your workspace was 30 feet in length? that’s going to take some time.
A spirit or bubble level has a vial (some have multiple vials) that are mostly filled with a liquid, usually a colored alcohol. Because the vial isn’t entirely filled, there is a bubble in the tube.
If you place the bubble/spirit level is placed on a truly level horizontal or vertical surface, then the bubble will stay in the middle of the gauge.
Though, unfortunately, the middle of the gauge can be off by a few millimeters, which will throw off your accuracy. Also, if you are working in an incline or decline, it’s next to impossible to keep your level at the same inclination, even more so if you are moving in the process.
Think, putting gutters onto your home or garage, and you want a slight incline/decline to ensure the water runs into your downpipe.
These situations are where laser levels shine and are best used.
Here are some advantages to using a laser level over a spirit/bubble:
- Laser levels are easy to use – With a simple press of a button, you can create a guideline, check for alignment and even for squareness with no hassle. You don’t need to use a chalk line if you have a laser level.
- Highly accurate -laser levels are highly accurate, up to a fraction of a millimeter.
- Lasers levels work with inclines/declines – You can mount a laser level, so it maintains the same position while you complete your work. The settings do not change as you move them from one location to another, well unless you want them to.
What Can You Do With A Laser Level?
Over the years, laser levels have become smaller, more accessible, easier to use, more accurate, and much more affordable.
Today, laser levels aren’t just used in large construction projects, but also by do-it-yourselfers to ensure accuracy in their projects (me being one of them).
Laser levels are used for layout jobs that require high levels of accuracy. Think of hanging photo frames, that you want the level to each other, there’s nothing worse than one being out of level (unless that’s by design), for me, it’s one of those that once it’s been seen, it cannot be unseen and it’ll annoy me every time I see it.
Some common applications including installation of ceiling tiles, sewer pipes, or even the simple installation of chair railings.
Some indoor uses for laser levels
- Level floors with a single-line laser beam.
- Ensure walls are straight and perpendicular to each other using a three-beam line laser.
- Attached to a ceiling, it will help you with the installation of ceiling drops.
- A two-line later will help check for door or window heights
- Install chair rails and wainscoting in your home
- Use a tripod to install cabinets and trims, and even picture frames on your walls
- Match points on both the floor and ceiling
Some outdoor uses for laser levels
With a laser line detector or a rotary line laser, you can use your laser levels outdoors.
- Groud Surveying.
- Checking and aligning of posts and beams on decks, porches, and fences.
- Alignment of bricks and other masonry.
- Setting the layout of a new construction site.
- Check an area/site for elevation for improving drainage installation
- Can be used for contour farming for better irrigation
- Lining up plants when planting flowers
How to use a laser level
Setting up a laser level
- First, before you use your laser level, set it on a flat surface, I suggest using a tripod.
- If your laser level is manual, make sure that the bubble is in the middle (i.e., at the “level”). If it’s not, turn the screws near the vial until you reach level. Turn on the level and use it.
- If your level is a self-leveling laser, you will need a few seconds for it to level itself. Some units will emit a blinking light if it’s out of level. In this case, you will need to adjust the unit yourself, Turn on the level, and use it.
- If you don’t have a wall for your laser beam to reflect on, you can use a laser detector to find the beam. Check the manual to find out how your laser will signal “leveling.”
Hanging pictures with a laser level
You can see a detailed guide on my best laser level for hanging pictures guide
- Determine the height for your picture frame
- put a small mark on the wall to serve as a reference point of the topmost part of the frame
- Set your laser level on a tripod on level stable ground
- Turn on your laser level and align it horizontally with the mark you left on the wall and make sure your laser is level
- Now take a picture frame and measure the length from the top of the frame to the hanging mechanism
- use the distance you get from step four and measure the laser downwards to read that line
- Mark wall along this line as many times are you have frames to hang in the same location
- drive a nail into the marks you’ve made
- Place the picture frames onto the nails and check for alignment at the top using the laser.
Using Laser Level To Install Wall Tiles
Ever been into a hotel or home where the floor-to-ceiling tiles aren’t aligned, they are ever so slightly out of alignment? Doesn’t that annoy you? It does me!
They didn’t use a laser level, but you will, right?
As everything builds off of the first row, you can get that perfect row of tiles by following these steps.
- Create a 2-inch wide strip of straight board.
- Identify a point on your wall that’s a few inches off of the floor. Make sure that the distance from the floor to this point is less than the height of your tile.
- Turn on your laser level and align the horizontal line to the point you marked above.
- Line up the end of your 2-inch wide straight board with the laser line and screw the board to the wall.
- Rest your first row of tiles on top of this board, and this will make a perfectly level first row.
- Continue to up tiles up to your desired height on the wall.
- Once you’ve installed all the tiles, remove the baseboard.
- Now custom-cut tiles for the bottom so so you can keep consistent grout lines.
Using Laser Levels To Install Ceiling Fixtures
Floors and ceiling will typically have the same measurements, so if you are installing ceiling fixtures, it makes sense to lay them out on the floor first, trust me this helps prevent you from getting a stiff neck.
- Mark the position of your ceiling fixtures on the floor
- Put your laser onto a tripod and turn it on.
- Line up the downward-pointing beam to the center of the fixture marked on the floor.
- Use the upward-pointing beam to mark the location on the ceiling.
- On the floor, measure the length from the beam to the points where the fixtures will attach.
- Mark the measurements you found in the above step on the ceiling.
- Hold up the fixture to the ceiling and install it.
Benefits of a Laser Level
There are many benefits of using a laser level, whether you are working on a DIY project or a construction site. You can use them to keep pictures level, make sure a roof is built to the right incline, check a ceiling if it’s flat or not.
In addition to those, here are some of the many indoor and outdoor uses of laser levels.
- Align walls, cabinets, chair rails and shelves
- Install wainscoting, drop ceilings and chair rails
- Check heights of doors, ceilings, and roofs
- The setting of a grade for proper irrigation and/or drainage installation
- Carry out any type of basic surveys
- Layout flours in a flower bed
- and much more

Frequently Asked Questions (FAQs)
Which is the best line laser level for indoors?
For me, this is a toss-up. If you are a DIYer, then the best indoor laser level is the DeWalt DW088K. However, if you are a professional, then its got to be the Leica Lino ML180 for the best line laser level for indoors.
Which is the best line laser level for outdoors?
Again another toss-up, I personally love the DW089CG for outdoor use, but for professionals, the Craftsman 48250 is a better choice for the best outdoor line laser level. It offers a considerable projection range, it’s self-leveling and employs a double beam.
Which is the difference between a green laser and a red laser?
There are two significant differences between the two, green and red laser levels are first, that a green laser is 300% brighter than the red counterpart.
The result of this is you can see it at a considerable distance. The second comes down to power consumption. Green laser levels shine bright, and to do that, and they need to consume more power, so they have a battery life that’s much shorter than the red laser level.
Which is the difference between the visibility range and working range of a laser level?
The difference between the visibility range and working range is workability. If you have a laser that has a working range of 100 feet but is visible up to 500 feet, well, the later is useless.
It’s all about the working range; anything outside of that range will affect the accuracy of the beam. So when you are checking the specs of a laser unit, you should never check the visibility range, instead focus on the working range.
How Often Should My Laser Level Be Calibrated?
Most self-leveling laser levels do not need to be calibrated; however, if you want to be sure of its accuracy, you can take it to an accredited store every six months for a check-up.
This way, you can catch issues easily on, preventing the device from failure and from throwing out your projects.
Can I Check Calibration Myself?
Yes, you can. But to do so, you need to understand how levels work.
To calibrate it yourself, the most straightforward way is to project the beam or dot on a wall 5 to 10 meters away. Then turn the level 180 degrees and check that the lines match up with each other,
if they don’t, then the laser isn’t calibrated and must be returned or taken to a service center.
What is the Difference Between Red and Green Laser Beams?
Human eyes have evolved into seeing green light better than red so that green lasers can be seen at longer distances.
When used outdoors, usually in bright sunlight, green lasers can be seen much easier than red, red lasers can become next to invisible and require a laser detector.
