What is a laser level?
A laser level is an alternative to a traditional leveling tool. Laser levels work by projecting a laser light beam onto the surface you’re working with, allowing you to easily see and work with a level line.
Types of Laser Levels
There are several types of laser levels to choose from including cross-line, rotary, plumb, and combination. Cross-line lasers project both horizontal and vertical lines onto surfaces. Rotary levels, typically used by contractors, are extremely precise and often the most expensive laser type. Plumb levels measure the vertical line of a surface. Combination levels feature more functions than any other laser type, including the option to project both lines and dots horizontally and vertically.
Laser Level Range
Levels vary in the maximum distance they can reach. Some basic laser levels have a 20-ft. or 40-ft. visible range, ideal for projects like installing cabinets, hanging artwork, installing floor tile and more. For long-range visibility, there are more heavy-duty options like 500-ft. and 1,000-ft. laser levels. These are ideal for more in-depth, outdoor projects like leveling on a jobsite. When shopping for a larger laser level with long-range capability, look for designs that feature carrying handles to make transport easier.
Laser Color
Laser levels project either a red or green beam of light. If working indoors or in a smaller space, a red laser level will likely offer enough visibility for the job at hand. If working outdoors, in direct sunlight, or in a brightly lit area, green lasers are preferred. They offer more visibility than red laser beams. Some bright-green beam lasers are four times brighter than standard red beams. That said, red laser levels are typically more affordable than green options.
How To Use a Laser Level
Laser levels aren't difficult to use, if you choose the correct laser for the job. For example, if you're working outdoors, you'll want to ensure you have an outdoor laser level or an indoor/outdoor option. For most home DIY projects, you'll likely be working with a standard indoor line generator. To use this type of laser level, simply hold the level up the surface you're working on and check the bubble vial to read the laser. Reading a laser level is similar to reading a manual level. There are also self-leveling lasers that level automatically with the touch of a button. Before using any laser level, read the manufacturer's instructions to ensure you get accurate readings.
