Laser distance measures replaced the tape measure for room measurements, square footage calculations, and estimating takeoffs. Point the laser at a wall, press a button, and get an accurate reading without a helper. The Bosch GLM50C and Leica DISTO D2 are the two most popular models for contractors and real estate professionals. Both connect to smartphones via Bluetooth. The Leica costs more and does more.
Quick Verdict
The Bosch GLM50C does 90% of what most contractors need at $99. If you measure rooms under 150 ft and want basic Bluetooth documentation, it's the right pick. The Leica DISTO D2 is the better tool for estimators, real estate professionals, and anyone working in large spaces. The 330 ft range and DISTO Plan app are worth the $70 premium if you produce floor plans or measure commercial buildings.
No room in a house exceeds 165 ft. Color display and $99 price make it the practical residential choice.
330 ft covers warehouses, retail spaces, and open-plan offices. DISTO Plan produces client-ready floor plans.
DISTO Plan app generates dimensioned floor plans that meet MLS listing standards in most markets.

Frequently Asked Questions
How accurate are laser distance measures compared to tape measures?
More accurate on measurements over 10 ft. Both of these are rated at +/- 1/16 inch, which matches a carefully read tape measure. The advantage is consistency: a laser gives the same reading every time, while tape measures can sag, stretch, or be misread. Under 10 ft, a tape measure is faster.
Can I use these outdoors?
In shade, yes. In direct sunlight, the laser dot becomes invisible beyond 30 to 50 ft. For outdoor measurements past 50 ft, you need a laser detector target plate and a unit that supports it. The DISTO D2 has better outdoor performance due to its stronger laser, but neither includes detector support.
Do these replace a measuring tape entirely?
Not for marking cut lines, measuring trim lengths, or checking clearances under 6 ft. Laser measures are best for room dimensions, ceiling heights, square footage, and any measurement where you'd otherwise need two people and a 25 ft tape. Carry both.
