From the developer of Mila's Tools (Apple Staff Pick, 1,200+ reviews at 4.8). Find your perfect ring size in seconds. Seven international sizing systems on one screen — no charts to memorize, no guesswork. Mila's Ring Sizer & Converter is the standalone version of the ring sizing tool from Mila's Tools, the 29-category unit converter on the App Store since 2011.

Measure directly from your phone: * Match a Ring on Screen — lay a ring on the display and tap the circle that fits. US sizes 3 through 15 in half-size steps. * Measure with String — wrap a strip of paper around your finger, then read the length on a calibrated on-screen ruler accurate to 0.5 mm. A one-time screen calibration with a common coin ensures physical accuracy. 13 reference coins from major currencies are included — the app picks the right one for your region. Whether you're shopping for an engagement ring, ordering a wedding band online, sizing a surprise gift, or comparing international jewelry — type one value and every other standard appears instantly, or measure first and let the app do the rest.
