How to use laser level for framing (tricks and tips)

Using a laser level is one common way to help you with your DIY or professional projects and today we’ll talk about how to use a laser level for framing.

From tiling walls, to install decking, any kind of ceiling works like installing lights and of course set and frame walls amongst so many other applications that this tool can be used for … The laser makes it so that you can follow a benchmark accurately and with precision.

This ensures that whatever you are building will be level and straight.

There are a few different types of laser levels available on the market and here’s a nice list that includes, amongst others, some of the best cross line laser levels for framing basements or walls. You can find small handheld torpedo levels, self-leveling cross-line levels, laser level squares, and 3 or 5 points self-leveling laser, rotary laser levels and so on.

Normally, when framing walls in an existing space, you would use a chalk line as a guide to set your walls. And sometimes I’ve seen some older colleagues still using the water level vs using a laser level. But this can lead to frustrations as the line will often fade and can be hard to see. Plus, in the case of the water level, it can be a hassle since you’ll need two people to carry out the measurements.

You can make this task much easier by using a laser level to project a line across the floor, walls and/or ceiling. The laser will ensure that your line is perfectly straight and will not fade with time.

Tips and tricks to better understand how to use a laser level for framing

Tip #1  Leveling

Laser Levels should always be set up on a firm and solid surface. Laser levels work by projecting a perfectly straight beam of light. This means that if you have the level set up on an uneven surface, you will be projecting a crooked line and will not get accurate measurements.

Most heavy duty laser levels have a self-leveling device inside them that will automatically correct this problem. However, if you are using a smaller, torpedo-style level, you will want to ensure that it is set to level before using.

Tip #2  Find High and Low Spots

When building or framing a wall, you will want to make sure that the floor you are building off is also level. You can do this by setting your level to project a horizontal line across the room where you want your wall to be.

Next, use a tape to measure the distance between the beam and the floor, making notes of any spots that are significantly lower or higher. You may want to level out these spots before beginning to frame your wall.

Tip #3  Framing Walls

To use a laser level to frame a wall, you will want to set it up so that it projects a vertical beam. Next, you will want to set the laser up with wherever you want your wall to be. This should project a solid, laser line across the floor and up onto the ceiling.

Use this line to build up to with your wall’s bottom and top plates or you may choose to make a benchmark where the line is, turn off/put away the laser and then build off your markings. For framing walls, it might be best to use a self-leveling laser device. 

Tip #4  Check Your Work

Laser levels are a great way to check your work as the job progresses along. While framing a wall, you can do this by setting the level to a vertical beam and lining it up with your work.

By judging the distance between the laser beam and your framework, you will be able to tell if your wall is leaning in or out and make any adjustments as needed. Be sure to check your work often or simply keep the laser turned on while you are working.

Another little thing I’d like to mention at this stage is that if you use a green beam laser level vs a red beam laser level, you’ll be able to see the laser line much better and make your layout more accurate.

  • Laser levels are generally safe to use, although the laser beam can cause damage to your eyes. Remember to always use personal protective eyeglasses and never point the laser at your or anyone else’s eyes.
  • Self-leveling laser devices are quite fragile, and one should always take care when handling them. A self-leveling laser that has been dropped or has experienced a severe-enough shock could malfunction and not level itself properly.
