Ring Sizer: Measure Ruler

Ring Sizer is a simple on-screen tool to find your ring size at home.

Place a ring on the screen and resize the guide until it matches the inner edge, or measure your finger with the stencil and side slider. Ring Sizer also includes a real centimetre and inch ruler. Get clear US, UK, and EU sizes, save measurements on your device, and calibrate with a bank card for better accuracy.
