9 Best Laser Levels [Tested and Reviewed]
Laser levels significantly enhance the quality of DIYs, renovations, and remodeling. By emitting a laser, they display horizontal and vertical lines on walls and other surfaces, which are used to attach building materials to walls and install furniture.
Using a laser level improves the overall appearance of renovations and reduces the chance of gaps and misalignments in building materials. They are perfect to have if you undertake large-scale DIYs or renovation projects. Major power tools manufacturers, such as Bosch and DeWalt, and surveying equipment manufacturers, like Huepar and CIGMAN, all sell their own models. And, they can vary in price due to their features, accuracy, and durability, which can make it tough to choose which one to buy.
At mybest, we define the best laser level as one that projects an easy-to-see laser that can be used over a long period indoors or outdoors. We compared 9 of the best-selling laser levels available from the top makers and online retail sites to help you meet your match.

Accuracy is Not a Function of Price
Laser levels are mostly accurate despite the model because most use a pendulum-style system to determine horizontal levelness and vertical plumbness. So if you are starting out, go with an inexpensive model, one that matches your degree of DIY knowledge. When you start getting concerned about usability, consider upgrading to a laser level that offers more features and attachments.
How to Choose Laser Levels
Check for Visibility—Brightness, Color, and Thickness
Other than accuracy, visibility is the second most important attribute to have in a laser level. The 3 big issues when it comes to visibility are the brightness of the laser, its color, and its thickness.
CIGMAN Offers and Easy-To-See Laser Line
We found that CIGMAN’s Self-Leveling Laser Level has a laser line that’s easiest to see. The laser is visible even in the bright outdoors, making it more versatile and ready to use wherever you need it.
Look For a Brightness of Over 500 Lux
The brightness of the average living room is about 200 lx, and the shade on a sunny day is about 10,000 lx (reference: International Lighting Commission). To see a laser level’s laser line, its brightness should be at least 500 lx.
With indoor lights on, our testers had the easiest time seeing lasers if they were over 500 lx. More is OK, but less means that the laser level can be used only under average or dark conditions.
If you work primarily outdoors, we recommend purchasing a device with a receiver. Such laser levels are expensive and intended for professionals, so they were not included in our tests. However, with a receiver, even if the laser light is not strong enough and cannot be seen outdoors, you can determine the horizontal and vertical positions through sound and vibration.
Green Lasers Are Easier to See Than Red Ones
Laser levels come in a variety of line colors, with blue, green, and red being the most common. However, green lasers are easier to see because green hues have wavelengths near 555 nm, and the human eye sees that wavelength easier than others (Commission internationale de l'éclairage).
The various color tones of the laser levels we reviewed can be seen in the gallery at the bottom of this article. The pictures may differ from the product's actual color depending on the environment it was displayed in, but you can make a relative comparison.
Thin Laser Lines Are Better
A laser level should support construction according to a blueprint, but during our tests, we found that some levels made it difficult to mark accurately along the beam. We activated the beam 15 feet from a wall and measured the thickness of the line. Using a chalk line tool, we tried to draw a steady line with a width of approximately 0.07 inches. If the width of the beam was 0.1 inches or greater, it was much more difficult to get accurate chalk lines.
Adjusting Tripods and Rotating Platforms
Precision and visibility of lines are crucial during marking. If you can't adjust them accurately, problems arise later. So, we investigated what kinds of products are easy to set up and adjust.
Elevator-Style Tripods Make Height Adjustments Smoother
Laser levels that can be mounted on an elevator-style tripod are great because they allow for fine adjustments to horizontal line heights. Few laser marking devices can adjust horizontal line heights themselves, and none of the products we tested could do so. Matching horizontal heights is accomplished most easily using an elevator-style tripod, most of which have 5/8 inch diameter attachment points.
If a tripod cannot be used, other means of leveling the laser must be used. Magazines, books, and toolboxes are commonly used for this purpose. However, they cannot offer the accuracy that a tripod offers.
If you're considering purchasing an elevator-style tripod, we recommend one with a handle. With this, not only can you adjust the height of the horizontal line, but you can also adjust the projection angle of the vertical line simultaneously, making it highly efficient and accurate.
A Rotating Platform Allows for More Precise Movement
A turntable-style rotating platform allows for subtle vertical line adjustments on a laser level, making work more efficient and accurate. Without one, you must adjust the laser’s projection position by shifting the main body’s position, but a 0.5 inch deviation by hand can become a 5 inch deviation by the time the laser reaches the wall. Manual positioning thus requires dexterity, experience, and some luck.
Most manufacturers of the laser levels we tested sold turntables separately. If you're working with detailed blueprints, it is best to choose a product with a turntable included.
Indoor Renovations Require Lasers That Can Be Projected Directly Below or Behind an Object
If the projection range is narrow, you must adjust the horizontal and vertical orientation repeatedly during major renovations, such as when framing or renovating an entire room. If a laser level allows projection in all directions, adjustments are reduced. By reducing the number of adjustments, errors are less likely to occur.
Long-Range Lasers Are Preferable
The longer a laser level’s laser can reach, the less time is spent moving it closer to walls and other surfaces when measuring. Some levels also allow projection forward, back, left, right, up and down, again saving time by not having to move and adjust the level. Consider carefully how you intend to use your laser level, and choose one that matches these requirements.
Battery Life Varies
During testing, we measured the time each laser level’s battery lasted by using them continuously on their highest setting. Some laser levels use rechargeable batteries and some use alkaline batteries. Among those that use alkaline batteries, some use two AAs and some use three. Despite their power source, batteries lasted longer in some laser levels and shorter in others.
A Level With Three AA Batteries for Longevity
If you are going to work in the same place for several days, we recommend a laser level that uses three AA batteries. We found that rechargeable laser levels emit light continuously for an average of 7 hours, but those powered by two AA batteries lasted an average of 10 hours. Those that take three AAs lasted for 13 hours, on average. If you use a laser level for 3 hours each day, its batteries will last two weekends of renovations.

Suitable for Use on Large Walls; Long Battery Life
What we loved
- ・Laser reaches distant walls
- ・Long battery life
What we didn't love
- ・Dim red laser not suitable for outdoor use
- ・Fine adjustments difficult due to mounting limitations
DeWalt’s Cross Line Laser DW088K is a low-priced laser level that operates on three AA batteries. Illuminance at 15 feet was 427lx, which is dim, and its red laser at 635 nm was difficult to use outdoors. The line width is thick at 0.07 inches, but from a distance, it still projects to walls well enough to use indoors.
The magnetic attachment is fixed directly to the main body, so it cannot be rotated 360 degrees. No 5/8 inch mount means that this laser level cannot be used with a tripod, so adjustments from measurement to measurement take more time. Battery life was 14.2 hours, so long-term construction won’t be interrupted looking for batteries.

What we loved
- ・Vertical range is wide
What we didn't love
- ・Short battery life
- ・Red laser is dim and thick
Bosch’s Self-Leveling Cross-Line Laser is a low-cost model that operates on two AA batteries. At 15 feet, the illuminance was 434 lx, which is somewhat dim. The level’s red line at 637 nm was difficult to see and thus not suitable for outdoor use. The width of the line was 0.07 inches, which is too broad for precise measurements.
Vertical lines to the ceiling and floor project over a wide area, but horizontal lines have a narrow projection range. The level does not have a 5/8 inch mount for a tripod, but it does have dedicated clamps, so when working in a large room, it takes time to readjust the level. The batteries lasted 45 minutes, which is quite short. Expect frequent battery changes during a day’s work.

What we loved
- ・Bright green line
- ・Dedicated clamp
What we didn't love
- ・Dashed line
- ・No rotating platform
- ・No tripod mount
SKIL’s Self-Leveling Green Cross Line Laser has a low price point and is powered by a rechargeable battery. In a pinch, it can also be powered by a cable. Illuminance at 15 feet about 534 lx, and its green line at 517 nm is easy to see, even outdoors. However, the line is dashed rather than solid, and at 0.1 inches, this combination made it difficult to both find the center mark and make precise measurements.
Vertical lines to the ceiling and floor illuminate a wide area, but horizontal lines have a narrow range. No 5/8 inch mount is available on this laser level. It does have a dedicated clamp, but that means that adjustments are needed often when working on an entire room, which wastes time. Batteries lasted 6.9 hours, so you will get about a full day’s work without having to recharge.

Accuracy
We conducted tests on each product by first setting the standard for accuracy as a level that projects accurate horizontal and vertical markers.
Scoring Method
We hung a pendulum and set up each level at a distance of 15 feet. We then measured the alignment of the level using the pendulum and a protractor. We measured whether there was any deviation from 90 degrees for horizontal lines and similarly any deviation from 0/180 degrees for vertical lines. The more accurately a laser level produced horizontal and vertical lines, the higher we could recommend a product. We scored these recommendations under several test conditions.
Test Conditions
- Test equipment: Drop swing (Tajima G3 300), Protractor (Shinwa Protractor)
Test distance: 15 feet
Visibility
We set the standard for an easy-to-see laser level as one that could be seen clearly, even outdoors. We then conducted tests of each product to ensure user satisfaction.
Scoring Method for Brightness
We used specialized equipment to measure the brightness of each laser level in lux (lx). We established a baseline of 400 lx, which was clearly visible in a 200 lx room. We set the upper limit at 800 lx, which would be clearly visible outdoors. We then rated each level on visibility, recommending those whose lasers could be clearly seen outdoors.
Test Conditions for Brightness
- Test equipment: Illuminance meter (HIOKI FT3425 LUX METER)
Test location: Room brightness set to 200 lx to 300 lx
Scoring Method for Line Thickness
The laser levels were activated from a distance of 15 feet. Since thinner lines are easier to trace with chalk and other marking tools, we recommended those with thin lines.
Test Conditions for Line Thickness
- Test equipment: Vernier caliper (Shinwa Digital Vernier Caliper 150 mm 19995)
Measurement points: Four points at a distance of 3 inches from the intersection of horizontal and vertical lines
Measurement distance: 15 feet
Scoring Method for Color
We used dedicated equipment to measure the wavelengths of the lasers. The closer they were to 555 nm, the more we could recommend them.
Test Conditions for Color
- Test equipment: Spectral radiometer (UPRtek MK350 LED Meter)
Measurement points: Intersection of horizontal and vertical lines
Measurement distance: 15 feet
Laser Direction
We set the standard for a wide projection range as a level that does not require installation or adjustment each time it is projected. We tested each level using the following methods.
Scoring Method for Laser Direction
Our testers assessed each laser level and scored them based on the following points to quantify a recommendation.
Testing Method for Laser Direction
- to the front
to the back
to the right
to the left
onto the ceiling
onto the floor
vertically
Scoring Method for Laser Range
We secured the product to a corner of a room that is approximately 144 square feet, directing the laser level forward. We measured the length of the lines projected onto the ceiling, floor, and both right and left walls, calculating the ratio of line length to the walls. We scored each level from 0% to 100%, with those having longer lines being more highly recommended.
Test Conditions for Laser Range
- We set each laser level to 3 feet off the floor.
Ease of Installation and Setup
We set the standard for ease of setup as a laser level that didn’t require any special techniques or skill to install and adjust. We also looked at whether it came with any accessories to support the adjustment. We tested each level using the following methods.
Scoring Method
Our testers assessed each level and scored it based on the following points.
What We Checked
- Rotation range and method
Compatibility with tripods
Presence of a rotating base
Method of angle adjustment
Ease of switching between horizontal and vertical lines
Presence of a receiver
Battery Life
We set the standard for battery life as a laser level that wouldn’t run out of power even if left on and used during an entire weekend. We then tested each level in the following way.
Scoring Method
We measured from the time each level was activated to the time that the laser shut off due to insufficient power from the battery. Assuming that intermediate DIYers work on weekends, we set 12 hours as the upper time limit. We rated each level based on whether its battery would last for an entire weekend of work.
Test Conditions
- We operated each level in all directions that it was capable of projecting simultaneously
If adjustable, we operated the level at maximum output, without using energy-saving mode
