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 โข 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. โข Measure a finger: rest your finger on the screen and fit the circle to the widest part of the base, just past the knuckle. โข Fine-tune in 0.1 mm steps โ one full ring size is only about 0.8 mm, so precision is everything. โข Between sizes? Mesurix tells you which one to choose, so the ring always passes the knuckle. EVERY SIZE STANDARD AT ONCE โข Instant conversion chart: US/CA, UK/AU, EU/ISO millimetres and Japan โ side by side. โข Pick your preferred standard in settings; switch anytime. โข See the exact inner diameter in mm behind every size. ON-SCREEN RULER โข A real calibrated ruler in mm, cm and inches, with a draggable guide line. โข Calibrate once for your exact display โ re-calibrate anytime for any device. โข Copy the measured value with one tap. BUBBLE LEVEL โข Surface mode: lay the phone flat and level anything with a live x/y bubble. โข Edge mode: rest the phone on its edge and read the angle in degrees โ hang shelves and frames straight. โข Set zero on any known-flat surface to cancel sensor bias. SAVE, SHARE, PRINT โข Save sizes โ yours and the people you choose gifts for. โข Share a size in seconds when you order a ring online or at the jeweler. โข 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.

Ring Sizer is a simple tool for checking ring size directly on your iPhone. Open the app, place a ring on the screen, and adjust the circle with the smooth slider until it matches the inside edge of the ring. The selected size and inner diameter are shown clearly, so you can check the result without searching through conversion tables. The app supports JP, US, EU, and UK size systems. It automatically chooses a default based on your device language and region, and you can change it anytime from the size menu. The slider moves by size steps with subtle haptic feedback, making the measuring experience quick and satisfying. You can also save sizes for your own fingers. Store sizes for the left and right hand, from thumb to little finger, and review them later in the My Fingers tab. Ring Sizer is designed with a calm, feminine beige style that keeps the measuring circle easy to see while still feeling polished. It is perfect for checking rings at home, comparing sizes before shopping, or keeping a personal ring-size note.
