Mini Digital Measuring Wheel
Your tape measure was built for straight lines. Your projects aren't.
A rounded table edge. A curved sofa arm. The circumference of a pipe. A steel blade buckles, slips and makes you guess, and a guess is how you end up cutting twice.
It bends where it shouldn't
Stiff blades can't follow curves, so you estimate and hope.
It needs a second pair of hands
Long runs mean someone holding the hook at the other end.
It's easy to misread
Tiny tick marks, bad angles and scribbled notes add up to costly errors.
Three seconds from pocket to precise
No hooks, no helpers, no squinting. Pick a mode, roll, read.
Step 1
Choose your mode
Press once to switch between straight, curve, diameter and cumulative modes. Tap again to change units.
Step 2
Roll along the surface
Place the wheel on your starting point and roll. The built-in encoder tracks every millimeter, even around bends.
Step 3
Read, hold and save
Press HOLD to freeze the number on screen. It's stored automatically, with your last 10 readings ready to recall.
Millimeter readings you don't have to interpret
A high-precision digital encoder counts every turn of the wheel and shows the result instantly on a crisp 1.8-inch display. No parallax, no rounding, no "was that 47 or 48?"
- White-on-black VA LCD, readable at any angle
- One-click switching between cm, m and inches
- HOLD button freezes the reading on screen
Pocket-size, workshop-tough
At 53 mm across and 15 mm thin, RollMeasure slips into a jeans pocket, apron or toolbox tray. The aluminum alloy body is wrapped in silicone for grip and finished with a sandblasted matte surface.
- Aluminum alloy + silicone construction
- Scratch-resistant 4H plexiglass screen cover
- No metal blade to snap back or pinch fingers

Questions, answered
Everything people ask before switching from a steel tape.
How accurate is it?
RollMeasure gives millimeter readings from a built-in high-precision digital encoder. For best results, keep the wheel in full contact with the surface and roll at a steady pace.
Can it really measure curves and circles?
Yes. Because it measures by rolling, it follows the actual surface: arcs, rounded edges, irregular outlines and the circumference of pipes, pots or columns.
What's the maximum length it can measure?
Up to 99 meters in cumulative mode, so you can measure long runs alone, without a helper holding the other end.
Which units does it show?
Centimeters, meters and inches. Switch between them with a single press, even after a measurement is taken.
How does the memory work?
Press HOLD to freeze a reading on screen. Your last 10 measurements are stored, so you can measure a whole room or garment first and write everything down later.
How do I charge it, and how long does the battery last?
Charge it with the included USB-C cable. The 200 mAh battery and low-power chip give up to 200 days on standby; actual use time depends on how often you measure and the backlight setting.
Is it durable enough for job sites?
The body is aluminum alloy wrapped in silicone, and the screen is protected by 4H hardened plexiglass. It comes with a protective case for your toolbox or bag.
How long does shipping take?
