Bosch GLM 50 Cx Laser Distance Measurer Review

A laser distance measurer is one of those tools that seems like an unnecessary upgrade from a tape measure right up until you use one for a real project, and then you wonder how you ever measured a room, framed an opening, or estimated flooring material without it. We used the Bosch GLM 50 Cx across a flooring estimate, a room addition layout, and general shop measuring for six weeks.

What We Tested

Room area and volume calculations for a flooring bid, indirect measurements using the Pythagorean function to find heights we couldn’t measure directly, Bluetooth data transfer to the Bosch app for a floor plan sketch, and accuracy checks against a steel tape at distances from 3 feet to 100 feet.

Full Specs

Performance

Accuracy held up exactly to spec across every distance we tested, including in a sunlit room where cheaper laser measures sometimes struggle to hold a reading. The indirect measurement function — using two angled readings to calculate a height or distance you can’t measure directly — is the standout feature. We used it to get an accurate ceiling height reading without a ladder, which saved real time.

The Bluetooth sketch function in the companion app is a nice touch for anyone doing floor plans or submitting material estimates, though it’s more useful for occasional users than pros who likely already have dedicated layout software. Battery life easily covered a full week of daily use before needing a charge.

How It Compares

Vs. the Leica DISTO D2: Leica’s accuracy is marginally tighter and the build feels more premium, but it costs significantly more and lacks the area/volume functions built into the Bosch at this price point.

Vs. a basic sub-$30 laser measure: Budget laser measures handle simple point-to-point distance fine, but lack the indirect measurement and area/volume calculation that make this tool genuinely useful for planning work, not just measuring.

Who It’s For

Ideal for anyone doing flooring, drywall, paint, or material estimates where area and volume calculations save real time, and for DIYers tackling room additions or renovations who need accurate measurements without a second person holding the other end of a tape. If you’re only ever measuring straight lines under 25 feet, a good tape measure still does the job for less.

Pros

• Accurate to spec even in bright, sunlit conditions
• Indirect measurement function replaces a ladder for many height readings
• Built-in area and volume calculation speeds up material estimates
• USB-C rechargeable, no proprietary batteries
• Bluetooth app sync for sketching floor plans

Cons

• App sketch function feels more like a bonus than a core tool
• Small buttons can be fiddly with gloves on
• Pricier than basic point-to-point laser measures
