Which size?

Find your ring size in a minute

Your screen becomes the sizer. On most phones it is already true size, and a quarter lets you check. Then measure the finger you will wear the ring on, with a ring that already fits that finger or with a strip of paper.

1. Check the screen with a quarter

Lay a quarter flat on the screen, over the coin, and move the slider until the coin on the screen is exactly the size of yours. No quarter? Then the circle and the ruler are not to scale: measure your paper strip with a real ruler and set that number in millimeters on the strip slider, then send it to the desk.

2. Measure

Take a ring that fits the same finger of the same hand the new ring will live on; every finger is its own size. Set it on the screen over the circle and move the slider until the circle just fills the inside of the ring.

A screen measurement checked with a quarter is a guide, good to about a half size; the desk sizes you right the first time. "Rings here listing it" counts the live listings on October 2, 2026; the sales lines are engagement rings sold here in the year to September 26, 2026, with a size recorded.

Keeping it a surprise? Borrow a ring she already wears, ideally from her ring finger, and lay it on to read its size. Or ask a friend or family member you trust, someone who won't spill the secret, for her size and the stone she likes. Still not sure? Ask a jeweler.

Another metal, karat or size, or an engraving? Ask a jeweler before you buy. Custom work and resized rings are final sale.
