Ring Sizer & Ruler

Mesurix finds your ring size right on your screen. No plastic sizers, no printable guesswork charts, no waiting for a kit in the mail — measure a ring or a finger in under a minute and get the size in every major standard. RING SIZER — TWO WAYS TO MEASURE • Place a ring: lay any well-fitting ring flat on the screen and scale the circle until it matches the inside edge. The most accurate at-home method. • Measure a finger: rest your finger on the screen and fit the circle to the widest part of the base, just past the knuckle. • Fine-tune in 0.1 mm steps — one full ring size is only about 0.8 mm, so precision is everything. • Between sizes? Mesurix tells you which one to choose, so the ring always passes the knuckle. EVERY SIZE STANDARD AT ONCE • Instant conversion chart: US/CA, UK/AU, EU/ISO millimetres and Japan — side by side. • Pick your preferred standard in settings; switch anytime. • See the exact inner diameter in mm behind every size. ON-SCREEN RULER • A real calibrated ruler in mm, cm and inches, with a draggable guide line. • Calibrate once for your exact display — re-calibrate anytime for any device. • Copy the measured value with one tap. BUBBLE LEVEL • Surface mode: lay the phone flat and level anything with a live x/y bubble. • Edge mode: rest the phone on its edge and read the angle in degrees — hang shelves and frames straight. • Set zero on any known-flat surface to cancel sensor bias. SAVE, SHARE, PRINT • Save sizes — yours and the people you choose gifts for. • Share a size in seconds when you order a ring online or at the jeweler. • Print a paper ring sizer to double-check before a lifetime moment — engagement, wedding, anniversary. PRIVATE BY DESIGN Mesurix works entirely on your device. No account, no sign-up — your measurements stay with you. Whether you are choosing an engagement ring, ordering jewelry online, sizing a gift without spoiling the surprise, hanging a shelf straight, or just need a quick ruler in your pocket — Mesurix gives you the right measurement the first time.
