Mesurix finds your ring size right on your screen. No plastic sizers, no printable guesswork charts, no waiting for a kit in the mail β€” measure a ring or a finger in under a minute and get the size in every major standard. RING SIZER β€” TWO WAYS TO MEASURE β€’ 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. β€’ Measure a finger: rest your finger on the screen and fit the circle to the widest part of the base, just past the knuckle. β€’ Fine-tune in 0.1 mm steps β€” one full ring size is only about 0.8 mm, so precision is everything. β€’ Between sizes? Mesurix tells you which one to choose, so the ring always passes the knuckle. EVERY SIZE STANDARD AT ONCE β€’ Instant conversion chart: US/CA, UK/AU, EU/ISO millimetres and Japan β€” side by side. β€’ Pick your preferred standard in settings; switch anytime. β€’ See the exact inner diameter in mm behind every size. ON-SCREEN RULER β€’ A real calibrated ruler in mm, cm and inches, with a draggable guide line. β€’ Calibrate once for your exact display β€” re-calibrate anytime for any device. β€’ Copy the measured value with one tap. BUBBLE LEVEL β€’ Surface mode: lay the phone flat and level anything with a live x/y bubble. β€’ Edge mode: rest the phone on its edge and read the angle in degrees β€” hang shelves and frames straight. β€’ Set zero on any known-flat surface to cancel sensor bias. SAVE, SHARE, PRINT β€’ Save sizes β€” yours and the people you choose gifts for. β€’ Share a size in seconds when you order a ring online or at the jeweler. β€’ Print a paper ring sizer to double-check before a lifetime moment β€” engagement, wedding, anniversary. PRIVATE BY DESIGN Mesurix works entirely on your device. No account, no sign-up β€” 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 β€” Mesurix gives you the right measurement the first time.
