Step 2: Place the Laser Level in One Corner

Place the laser level in one corner of the room and make sure that it is pointing straight up and down, perpendicular to the floor. This will be your reference point for squaring the rest of the room.

Step 3: Measure The Wall Length

Measure the wall length with a tape measure and make sure that it is exactly square. Make sure that there are no protrusions or irregularities on the wall, as this will throw off your measurements.

Step 4: Position the Laser Level in The Opposite Corner

Now position the laser level in the opposite corner of the room and make sure that it is still pointing straight up and down. This will be your reference point for squaring the rest of the room.

Step 5: Drill Wall Plugs & Secure Them With Screws

Once you are satisfied that the laser level is positioned correctly, drill wall plugs into the walls at both corners and secure them with screws. This will provide a solid anchor for the laser level, ensuring that it remains in the correct position.

Ensuring That It Remains in the Correct Position

Now that your laser level is securely positioned in both corners of the room, you can use it to check that all four walls are square and that everything lines up correctly. And once you are happy with the results, simply remove the wall plugs and screws, and the job is done. With just a few simple steps, you have successfully used a laser level to square your room!
