Best Laser Levels

A laser level is one of those tools that once you use it you wonder how you ever got by without it. They can be broken up into three different types: plumb or dot lasers, line laser levels, and rotary lasers.

Plumb or dot lasers project a dot onto a surface as a reference point, sort of like a laser plumb bob. These are the simplest and cheapest models, but help the least.

Line laser levels emit a beam in the form of a level line onto a wall or workspace. They are designed to fan out to the widest angle possible which tends to be about 160 degrees for a vertical line and about 130 degrees for a horizontal line, although there are units that exceed 180 degrees including up to a full 360 degrees. There are also dual-beam or three-beam lasers that emit horizontal and vertical lines to establish both plumb and level.

If two lines can intersect then you might see that model referred to as a cross-line laser level.

These models are best used indoors and in shorter distances. You can use them outside, but it will be extremely difficult to detect the laser in daylight.

Rotary laser levels are a special type of laser level that has a rotating head that when spinning emits a laser beam in a horizontal level line around an entire space or 360 degrees. Some can be laid on their side to project a vertical line or have slope adjustments to change the angle of the line.

They are larger and cost more money, but usually work better at longer distances. They are primarily used outside, but you will probably need a laser detector to help you because it is difficult to see the laser in daylight.

Below we review the best laser levels including line levels and rotary lasers. Below each section we include a comparison chart so you can easily compare one laser level versus another.


Laser Line Levels

DeWalt DW089LG Green Beam 12V Battery

We selected the DeWalt DW089LG as the best laser level. However, it is on the expensive side at about $429. The reason for the high price is because it projects three 360 degree green lasers – 2 vertical and 1 horizontal. That makes it perfect to do full room layout without having to move the laser level.

Powered by a 12V li-ion battery, the DW089LG has a visible working range of 100 feet and a 165 feet range with laser detector all while being accurate to 1/8″ at 30 feet. In addition to the battery it comes with a charger, magnetic bracket with 1/4″ and 5/8″ thread, and green enhancement glasses all in a hard case.

While being an outstanding choice for professionals, you can save some money and avoid the DeWalt DW089LG if you do not need full 360 degree coverage or three beams. Potential buyers could also consider the red laser version for around $395 (comes with holder for 4 AA batteries instead of 12V).

Bosch GLL3-330CG

The $529 Bosch GLL3-330CG is very similar to the DeWalt DW089LG with two big differences – the working distance and price. The GLL3-330CG uses a brighter green laser that provides a range of up to 200 feet, however the price point is $100 more than the DeWalt.

The Bosch GLL3-330CG projects three 360-degree lines, two vertically and one horizontally, with an accuracy of ±3/32 inch at 30 feet. It is powered by a 12v li-ion battery and can be controlled across the room on your smart phone using the Bosch app. It also comes with the BM1 Positioning Device for line lasers which is a versatile mounting device with microfine adjustments.

The red laser version, the Bosch GLL3-330C, is also available and is about $80 cheaper.

DeWalt DW088LG 12V Cross Line Laser - Green

If you only need two lines, one horizontal and one vertical, and also want bright green lasers then we recommend the $339 DeWalt DW088LG laser line level.

The DW088LG projects green self-leveling horizontal and vertical cross lines that are four times brighter than red lasers. This enables easy visibility for indoor use with a working range of up to 100 feet and accuracy of 1/8″ at 30 feet. The unit has a built-in magnetic bracket and is powered by a 12V battery which is included along with a charger.

The only slight negative is the price. There are some cheaper options available including the $170 DeWalt DW088LR which is essentially the same laser level but with a red laser instead of green.

Overall we highly recommend the DeWalt DW088LG for any type of construction work indoors and even some outdoor work thanks to its bright, crisp green laser lines.

The cheapest green laser level on our list is the $219 Bosch GLL75-40G. It emits two green laser lines, one vertically at 270 degrees and one horizontally at 180 degrees. While that is not whole room, 360 degree coverage, you won’t have any issues with the beams covering the entire length of a wall.

Powered by 3 AA batteries, the GLL75-40G is accurate to ±1/8 inch at 33 feet and has a working range of 75 feet. It comes with a magnetic L mount bracket.

The Bosch GLL75-40G is the perfect choice for anyone who wants two green cross laser lines, but doesn’t want to spend a lot of money on one.

Ryobi ELL1750 Multi Surface Laser Level

The cheapest line laser level to make our list is the Ryobi ELL1750 which sells for just under $30. It only emits one red beam that is not self-leveling with an accuracy of ±1/2 inch at 20 feet.

Powered by 2 AAA batteries the ELL1750 is a bit dim with a working range of only 20 feet.

Overall the Ryobi ELL1750 is definitely not for professionals, however it can be a useful tool for odd projects around the home like hanging pictures. Just remember it does not self level, so it can be a bit more difficult to set up and it is not very accurate either.
