How to Use a Laser Level? Complete Guide

Laser Level

Since the invention of the power drill, laser levels have been among the most innovative tools to enter the construction sector. Learning how to use a laser level can help you with many things from hanging a picture to professional building work.

This post guide explains every step required to set up your laser so that you get the most precise readings possible.

What is a Self-Leveling Laser Level?

When used correctly, a self-leveling laser level emits a laser beam that is perfectly level or plumb.

This tool offers a tremendous amount of freedom and possibilities as a replacement for a standard box level or plumb line, making tasks like laying tile, mounting cabinets, and exterior tasks like grading and masonry work easier than ever.

What is a Laser Level Used For?

When a straight and level reference point is required over a larger surface, laser levels are frequently used in these situations. They resemble a kind of visual chalk line. Use them for professional leveling applications such as mounting picture frames, installing dado rails, and other tasks requiring precise point transfer.

Laser Level

For both indoor and outdoor applications, laser levels are useful. The majority of them can be used with or come with a tripod. A laser tripod will give the laser more stability and support in professional applications, ensuring that you consistently get the most accurate results.

We advise you to think about getting a laser level that “self-levels.” These models offer the highest level of accuracy while being the most user-friendly. For all kinds of plumbing and leveling tasks, they are perfect.

How to Use a Laser Level?

Let’s start setting up a laser now that we have a better understanding of what they are and how they work. You can get to work right away with a laser because they are frequently quick and simple to use. Please be aware that there are many different kinds of lasers available, and they may operate a little bit differently. But for the most part, to operate your laser:


  1. Place the laser level on a flat surface or a tripod.
  2. If it’s a manual level, make sure the bubble vials indicate level. Near the vial, locate the tiny screws. They should be adjusted until the bubble vials indicate level.
  3. Activate the laser level.
  4. Give the self-leveling model some time to complete its task.
  5. Depending on the type of laser level, the device emits a laser that indicates level on a wall or across an outdoor workspace. The laser can be a dot, multiple line, or rotary laser that indicates level at 360 degrees horizontally or vertically.
  6. You may use a laser detector to intercept the laser if there’s no wall to “catch” it (typically outdoors).
  7. Set up a measuring rod in front of the detector.
  8. When the detector starts to beep, move the detector up and down the rod. The detector has located the laser, so this indicates.
  9. Once you’ve located level, fasten the detector to the rod and take any necessary measurements.

Buying Vs. Renting a Laser Level

Should you purchase a laser level for the task at hand or just rent one? What you need is what determines the answer. Buy your own if all you require is a standard line laser and you intend to use it more than once. Even if you think you’ll use it just once, you’ll probably find lots of other applications for it later. Additionally, the majority of buyers can afford line lasers because of their low cost.

If you want to get an A+ on your patio installation and need a rotary laser, you should think about renting one. The average homeowner is unlikely to find enough uses for rotary levels to make it worthwhile to purchase them because they are much more expensive.

How to Choose a Laser Level?

  1. Aligning kitchen cabinets or framing pictures in a small, enclosed space are good indoor projects for multiple-line lasers. Use a laser square when working with masonry and tiles.
  2. Rotary and line lasers with a pulse/detector feature are good for long distances and uneven surfaces in outdoor projects.
  3. Think about the laser’s travel distance or the size of the room. Low rotations per minute (RPM) laser levels are bright and visible, but they don’t move very far. While the laser is fainter and travels farther at high RPM levels.
  4. Considering the wall’s type Suction cups or pins are used to attach laser levels. Avoid using push pin laser levels on paneling or wallpaper.
  5. Establish the job’s stability. For indoor projects, you can use a manual laser level. For outdoor projects involving uneven surfaces, you will need a self-leveling laser level.

When to Replace Your Laser Level?

When should I replace my laser level? The simple answer is when it breaks. It’s time for a new one if it is obviously incapable of carrying out the current task. Nevertheless, there are times when laser levels malfunction in less obvious ways that nonetheless have an impact on the performance.

Because of this, you should regularly check the laser level’s accuracy against a regular level and/or plumb line. Follow the instructions from the manufacturer if your laser can be calibrated, or send it in for calibration.
