Online measuring tape FAQ
Can an online measuring tape show actual size?+
It can show actual size after you calibrate on the same display and keep browser zoom at 100%. This tape uses the screen calibration you save in the main ruler, so verify it with a known object before measuring.
When should I use an online tape instead of an online ruler?+
Use the scrollable tape when a short on-screen ruler does not show enough length at once. It is still best for quick checks of flat, straight objects that can be aligned to the screen.
Can I measure around a curved object with this tape?+
No. A screen cannot wrap around an object, so use a flexible physical tape for body, furniture, pipe, or other curved measurements.
