This article will help you determine whether or not an indoor or outdoor rotary laser level is a best fit for your needs. Rotary lasers levels project a beam of light 360° allowing the user to establish a horizontal or vertical plane.


How to Choose a Rotary Laser Level

  1. For indoor projects: multiple line lasers work well for lining up kitchen cabinets or framing pictures in a small, enclosed room.
  2. For outdoor projects: use a rotary laser level on a secure tripod for uneven surfaces and long distances. Purchase appropriate colored goggles to see the beam more easily.
  3. Consider room size or distance for the laser to travel. Laser levels with a low rotations per minute (RPM) are bright and visible, but don’t travel far. High RPM levels travel further, but the laser is fainter.
  4. What is the stability of the job? You can use a manual laser level for indoor projects on a relatively flat work space. You’ll want a self-leveling laser level for outdoor projects with uneven surfaces.
  5. Do you have a level surface for the rotary laser level? You may use a bucket or sawhorse, but a tripod is the best option.
