About this tool
Measure small objects with your screen. The ruler shows centimetres or inches in the browser. Because every screen is different, you can calibrate it once with a bank card (85.6 mm wide) and the setting is remembered on your device. It is a handy guide, not a precision instrument.
When to use it
Measure small objects with an on-screen ruler in centimetres and inches, after calibrating it to your screen with a card.
Tips
Calibrate with a bank card, which is 85.6 mm wide, for a good match.

常见问题
How accurate is it?
After calibration it is usually within a millimetre or two. Browser zoom changes the size, so keep zoom at 100 percent.
How do I calibrate it?
Press Calibrate, hold a bank card to the screen and drag the slider until the blue box is the same size, then save.
Is it accurate?
Yes after calibration. Screens differ in size.
Can I measure in inches?
Yes, both cm and inches are shown.
