About

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 or size a finger — get the exact US, UK & EU size in seconds. No printing. No guessing. Ring Sizer is a subscription app. All measuring features — the On-Screen Ring Sizer, Finger Size Finder, conversion chart, and saved sizes — require a Ring Sizer Pro subscription to use. A free trial is available. Whether you're secretly sizing a partner's ring for an engagement, ordering a wedding band online, or checking your own finger before buying jewelry, Ring Sizer gives you a precise answer in under a minute — no jeweler visit required. 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 • Instant Conversion Chart — see your result in US, UK/AU, EU/ISO, and Japanese sizes, plus diameter and circumference in mm and inches PERFECT FOR A SECRET PROPOSAL Borrow a ring they already wear (from the correct finger!), place it on the screen, and get the size in seconds. Put it back before anyone notices. The surprise stays a surprise. WHY RING SIZER • Accurate calibrated measurement — the on-screen scale is calibrated to your exact device model • Every standard covered — full international ring size chart built in • Save sizes — keep your partner's, your own, and family members' sizes for future gifts • Works offline — measure anywhere, no connection needed • No printing rulers, no paper strips, no string tricks BUYING JEWELRY ONLINE? Online jewelry returns are usually caused by one thing: the wrong size. Measure once with Ring Sizer and order engagement rings, wedding bands, and everyday jewelry with confidence. TIPS FOR AN ACCURATE MEASUREMENT • Measure at the end of the day when fingers are at their normal size • Avoid measuring when hands are cold — fingers shrink • If you're between two sizes, choose the larger one • Wide bands fit tighter — consider going up half a size MEASUREMENT STANDARDS SUPPORTED US & Canada, UK & Australia, EU (ISO 8653), Japan, plus raw diameter and circumference in millimeters and inches. Download Ring Sizer today and never guess a ring size again.
