Bosch creates amazing tools that are loved by DIYers and professionals alike, and this laser tile square is no different, the laser beams are projected at 90-degree angles with a range of up to 30 feet. The angle can be adjusted in 5-degree increments. The dual laser lines turn on with a simple press of a button.

This model will project both horizontal and vertical lines that you can easily see on any surface. There’s a push-button that helps secure this level to a surface without the need of adhesives.

Working with this model outdoors will be a problem. When direct sunlight casts over the red laser beams, well, they become quite difficult to identity, so using this in bright lighting conditions isn’t going to work out very well.

This model can only project two lines, which for most purposes, is fine, but personally, I look for three or more lines to ensure that no matter that task, I am able to complete it.


  • Simple and easy to use
  • Great for the floors and quick wall hanging jobs
  • Low price


  • The laser line is only visible indoors

Best Laser Square Buyers Guide

Bosch GTL3 65ft Square Laser Level for Tile and Square Layout

A laser square is a cracking tool when you want to square up an area. A laser square will emit precise beams at either a straight line or at 90-degree angles, and some include the 45-degree angles as well. This tool eliminates chalk dust and the fuss required to put out strings.

Most laser squares turn on with a simple press of a button, instantly projecting their lines, making alignment quick and easy and much more accurate than rope lines or chalk lines.

You’ll find that there’s a wide range of laser levels on the market, and many that work well as laser squares, a lot have a laser square as an option.

Accuracy is obviously the most important factor, but there are also other important factors such as the brightness of the beam, the ability to adjust the angle, the working range, battery life, and warranty.

These features will vary from model to model, so you need to find a laser square that suits your needs, based on those factors.

Most specialist laser squares will come with preset 90-degree perpendicular beams. Some, however, will also include a 45-degree angle beam. The most advanced models will come with a self-leveling feature ensuring perfect accuracy.

Laser squares are often used as a laser level for laying tiles, which is a tedious job even more so when you use chalk lines or string.

Most come with a variety of mounting options, including magnetic plates and tripod brackets. though you may find they come with strips of adhesive.

Once you’ve mounted a laser square, it’ll stay in position throughout your project.


With any laser level, accuracy is the most important factor. Many laser squares work great for short-range projects. However, a lot don’t work over long distances. Accuracy various between models and manufacturers, so you should check that the working range meets your requirements

Range & Brightness

While the working range of a laser is great, the brightness will affect how far you can see the laser beam. The range of a laser square/level translates directly into how much area you can cover without repositing the unit.

Beam strength/brightness can drop quickly over distances in laser squares, even more so if direct sunlight is involved.

You can improve the situation by wearing laser detection glasses.

Mounting Options

When using a laser level regardless of whether it’s a laser square or a rotary laser level, you need it to be mounted securely. Otherwise, you can’t be sure of its accuracy. There are many different methods of mounting a level.

The most common is a hole in the housing where you attach it to a nail onto a wall. The better quality models will have support for tripods, magnetic plat mounts, etc.

I suggest you avoid the adhesive strips, I’ve never had good luck with them, and the glue on them doesn’t stick too well to a lot of surfaces, even more so if dust is present.

Battery Life

Bosch GTL3 65ft Square Laser Level for Tile and Square Layout

There’s nothing worse than your laser level just shutting down partway through a project. This is why battery life is important, can you switch up the batteries with new ones? or is it using a rechargeable pack?


Durability is given in an IP rating. Some models won’t have one at all, and others will be rated IP54 or higher, meaning that they are dust-proof and water-resistant.

You should choose a level that suits your working environment. If you aren’t working in wet or dusty environments, it doesn’t make sense to invest in a laser that is IP54 rated. These will come at an extra cost, one which you may not need.

I, however, have invested in on that’s IP54 rated as I’ve found even DIY jobs to be incredibly dusty, and I don’t want the laser to stop working because of dust.


Warranty isn’t something many factors into their buying decision, and for a good reason, a lot of laser squares are basically disposable, use them on the job site, get the job done, and replace them. But that’s a waste of your hard-earned cash.

So asides from investing in a decent quality durable laser square, look for one with two or more years of warranty, so you are covered should it stop working.

Tips on Using/Maintaining Laser Square

When you use your laser square, you want to make sure that you use it correctly that you get all the benefits of using a laser square.

Here are some simple tips to ensure you use your laser square properly.

Do not store this device in a hot area, or near objects that are emitting a lot of heat. Heat can shorten the lifespan of your laser square.

If your laser isn’t at least IP54 rated, then you need to make sure that you do not leave it outside in the rain. As soon as there’s a sign of water, quickly place it back into it’s protecting casing, also do the same when it’s not in use.

Before you move the device, make sure that it’s turned off, and make sure to store it where it won’t get knocked over by any other job site equipment that may be in the back of your pickup truck
