RingSizer vs Anella

RingSizer turns your iPhone into a precision jeweler's tool — no ring sizer, no guesswork, no trip to the store. MEASURE YOUR RING Already have a ring that fits? Place it flat on your screen and align it with the on-screen guide. RingSizer uses your device's exact screen dimensions — with optional bank-card calibration for extra precision — to calculate your true size. MEASURE YOUR FINGER No ring on hand? Use the two-step Ellipse Method. Fingers aren't perfectly round, so RingSizer measures both width and thickness for a scientifically accurate fit, based on the same math jewelers use. CONVERT BETWEEN SYSTEMS Instantly convert between EU, US, UK, Japanese, Australian and Swiss/German ring sizes — or look up any size by diameter and circumference.

Whether you're buying a ring as a surprise, replacing a lost one, or shopping online, RingSizer gives you a confident, accurate answer in seconds.

Lay a ring on the screen. Match the circle. Read your size. Anella turns your iPhone into a ring sizer. There is no camera, no account and no permission of any kind to grant — the measuring surface is the screen itself. MEASURED, NOT GUESSED Anella knows how many pixels your iPhone puts in a millimeter, so the gold circle you match is a real physical size. Every reading shows the millimeters beside the size, so you can always check the number the size came from. EVERY STANDARD AT ONCE US, UK, EU and Japanese sizes, side by side. The full conversion chart is free forever and searchable by any column. HONEST WHEN YOU ARE BETWEEN SIZES When a ring falls between two sizes, Anella says so: "between US 6 and 6½ — jewelers recommend sizing up." It never rounds quietly to look more precise than it is. CHECK IT AGAINST A BANK CARD Every bank card in the world is the same size (85.60 × 53.98 mm). Lay one across the two lines on screen, match its edges, and Anella calibrates itself to your exact display. NO RING TO HAND? MEASURE THE FINGER Two calipers you open around your finger, with the guidance to get it right. It is an estimate, and Anella says so on the result: a ring that already fits is always more accurate. SAVE SIZES WITH NAMES "Anna — 16.9 mm · US 6½". Months later at a jeweler's counter you will still know whose ring it was, and whether it came from a ring or a finger. ONE PURCHASE, YOURS FOREVER Try Anella with one complete measurement, free, and keep the size chart free forever. One payment then unlocks unlimited measuring, saved sizes, finger mode and all four standards at once. No subscription, no account, no renewal — and Family Sharing is on, so your family gets it too.
