Planning a surprise proposal but don't know their ring size? Ring Sizer turns your iPhone into an accurate ring measuring tool. Place a ring on the screen, size a finger, or use a simple piece of string — then read the US, UK & EU size in seconds. No printing. No guessing. Your first measurement is free, and the Size Converter is always free to use. Unlimited measurements and saved sizes for your whole family require a Ring Sizer Pro subscription. A free trial is available.

HOW IT WORKS • On-Screen Ring Sizer — place any existing ring on your screen and match it to the adjustable circle for an instant reading • Finger Size Finder — put your finger on the display and drag the sliders until they touch both sides • String Method — no screen to calibrate?
