Ring Size Finder & Measure

Find your ring size right on your screen — no printed sizer to order. RingFit turns your iPhone or iPad into an on-screen ring gauge. Calibrate your screen by matching a credit or ID card to the outline. Your calibration is saved for later measurements. • Measure a ring you already own, or your finger directly • One-time card calibration for your device's screen • Optional 3-measurement averaging • Your size across US, UK, EU, Japan, Türkiye and more • Save each size with a label and an optional photo • Share a size card with your jeweler • Built-in ring size chart Planning a surprise ring gift? Start with a ring they already wear on the intended finger. Results depend on careful calibration and placement; for the final fit, we recommend confirming with your jeweler. Measuring and viewing results require RingFit Pro or a single-use in-app purchase. A single-use purchase unlocks one result. Saving sizes, adding photos and sharing size cards require RingFit Pro. The ring size chart is free. RingFit Pro offers weekly and yearly subscriptions, or a lifetime purchase.
