The top 5 at a glance
A laser measure fires a small dot at the far wall and shows the distance on its screen at the press of a button. The simplest just measure; most also work out area and volume for flooring and paint, and the more advanced ones add an angle sensor for heights that a straight shot can’t reach.
Every one here reads to within 1/16 inch over a room’s length and comes with batteries in the box. Most keep past readings in memory, handy for measuring several rooms before writing anything down. A green dot is easier to spot than a red one in a sunny room or outdoors.
What matters
- A continuous or real-time mode that updates as you move.
- A backlit screen that’s easy to read in a dim closet.
- A dust and splash rating, IP54 or better, for outdoor jobs.
#1Bosch Blaze Pro GLM165-40 Laser Measure (165 ft)
$50–$75
Pocket-sized but fully featured: 165 ft of range to ±1/16 inch, a real-time mode that updates the reading as you move toward or away from a wall, area, volume and indirect height, add and subtract, and the last 10 readings stored. It’s sealed to IP54 against dust and rain.
What owners say: Owners say it’s accurate in feet and metric and lets them measure a whole house alone, one in under 10 minutes. A few find fractions of an inch hard to read on the display.
A closer look: Real-time mode is the trick for marking a set distance: walk the tool back from the wall until the number you want shows, then mark the floor. The five target cards in the box give the laser something to hit on glass or dark surfaces.
- Indirect height measuring
- Stores last 10 readings

#2Bosch Blaze GLM165-25G Green-Beam Laser Measure (165 ft)
$100–$150
Its green dot is up to four times brighter than a red one, so it stays visible in a sunny room or on a pale wall outside, and a rounding button gives the fraction you need. A full rubber overmold and IP65 sealing suit a job site.
What owners say: Owners like being able to see the green dot even in daylight, and find it easy to use and a time-saver. Opinions on the price vary, and some say it goes through batteries quickly.
Heads up: It runs on the two AA batteries in the box or Bosch’s optional 3.7V rechargeable pack, which is worth having if it’ll see daily use.
A closer look: Use the rounding button to snap readings to the fraction you’re cutting to before marking trim, baseboard or flooring. On a noisy site or with ear protection on, the haptic buzz confirms each reading when the beep can’t be heard.
- Green laser dot
- Rounding button for fractions
- Haptic buzz with each reading

#3Klein Tools Compact Laser Distance Measure (93LDM100C)
$30–$50
One button does everything: press for a single reading, hold for continuous measuring, and the last two readings stay on the screen to compare. It clips into a shirt pocket or safety vest and measures from 2 inches to 100 feet.
What owners say: Owners find it a handy little gadget indoors and easy to read in low light. The single button can feel fussy until it’s learned, and the screen washes out in sunlight.
A closer look: It measures distances only, with no area or volume sums, which is what keeps it simple; multiply length by width on a phone for a room’s square footage. Accuracy is tightest within 30 feet, which covers most rooms in a house.
- One-button operation
- Last two readings on screen
- Clips into a shirt pocket
Best for: Wall-to-wall lengths with one button
- Range
- 100 ft

#4DTAPE DT100 Laser Measure (330 ft)
$20–$30
The longest range here, with a 2-inch backlit screen, eight modes from area and volume to double Pythagoras, 30 stored readings and a switch to measure from the front or back edge.
What owners say: Owners find it far quicker than a tape for rooms, with a good-sized display and handy area and volume sums. Accuracy and screen readability get mixed reports, and some ran into error codes.
A closer look: DTAPE’s own tip for glass, mirrors and shiny tile is to stick a piece of white paper or tape where the dot lands. Set the reference to the back edge when measuring from a wall, and to the front when measuring from the edge of a table or step.
- Stores 30 readings
- Measures from front or back
- Pouch and hand strap
- 24-month warranty
Best for: Long distances, readings saved for later

#5MILESEEY D5 Laser Measure with Angle Sensor (229 ft)
$20–$30
A built-in angle sensor lets it work out heights and level distances from one slanted shot, handy for a ceiling above furniture or a wall with something in the way. It measures to ±1/16 inch over 229 ft and keeps the last 30 readings.
What owners say: Owners say it’s accurate and dependable indoors and in low light, and use it for the square footage of rooms and large spaces. Durability is mixed, and the dot is hard to see in bright sun.
A closer look: For the height of a wall with a cabinet in front, use auto-height: aim at the top and the bottom from the same spot and it does the math. The memory holds 30 readings, so every window can be measured for blinds and read back later.
- Built-in angle sensor
- Auto-level and auto-height modes
- Stores 30 readings
- Pouch and wrist strap
- 24-month warranty
