Laser levels project straight reference lines that speed up and improve the accuracy of many home-improvement tasks. Choose between cross-line and rotary styles, prefer green beams for visibility in bright conditions, and look for self-leveling and rechargeable batteries. Use them for hanging, shelving, tiling, and shop layouts, and always follow the manufacturer's safety instructions.

Quick way to straight lines

A laser level gives DIY projects a professional finish by projecting precise, straight reference lines across walls and floors. Modern units are compact, portable, and much faster to use than a long spirit level or a chalk line.

Types and features to look for

There are two common styles for homeowners: cross-line lasers that project horizontal and vertical lines, and rotary lasers used for long runs or exterior grading. Most consumer models now offer self-leveling so the tool sets itself within a small tolerance and alerts you if it's out of range.

Green vs. red beams: green lasers are generally easier to see in brighter conditions, while red lasers are common on lower-cost models. Many new units include rechargeable lithium battery packs with USB-C charging, making them ready with a quick cable top-up.

Accuracy and range
Manufacturers list accuracy and effective range for each model. Consumer cross-line lasers typically cover indoor jobs (tens of feet) with accuracies suitable for picture hanging, shelving, tile layout, and cabinet runs. For long outdoor distances, rotary lasers or a line laser with a detector are better suited.

Practical household uses
Use a laser level to align pictures and frames, set a straight chair rail or wallpaper border, install towel bars and shelves, lay tile, and check floor flatness. In a workshop, a laser makes cutting and joinery layouts faster and more repeatable than measuring and marking by hand.

Safety and best practices
Laser levels are low-power devices intended for layout work, but you should never stare into the beam or point it at other people's eyes. Follow the manufacturer's safety guidance and the laser class marked on the unit. For outdoor or long-range use, pair the laser with a detector if visibility becomes an issue.

Why buy one now
Today's laser levels are more reliable and convenient than older models. Rechargeable batteries, improved visibility, and self-leveling make them an efficient, long-lasting tool for homeowners and hobbyists. Add a compact cross-line laser to your kit and you'll save time while getting consistently straight results.

FAQs about Laser Levels

What can I use a laser level for around the house?
You can use it to hang pictures, align shelves and cabinets, install tile or wallpaper borders, set chair rails, and layout shop cuts - any task that benefits from a straight reference line.
Should I get a red or green laser?
Green lasers are easier to see in brighter light, while red lasers are common on lower-cost models. Choose green for better visibility indoors and outdoors when budget allows.
Do I need a special skill to use a laser level?
No. Most consumer laser levels are self-leveling and easy to operate. Read the manual for safety steps and basic setup, and practice on small tasks before using it on larger installs.
Are laser levels safe?
Laser levels are low-power, but you should never stare into the beam or point it at anyone's eyes. Follow the manufacturer's safety instructions and check the laser class marked on the device.
What about battery life?
Many modern units use rechargeable lithium packs and USB-C charging, which provide convenient runtime for typical home projects. For long outdoor jobs, carry spare power or a detector-equipped rotary laser.
