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