## What is 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.
