About this app

Mesurix is a ring sizer and ruler in your pocket. Find your ring size right on your screen — no plastic ring sizers, no printable charts, no waiting for a sizing kit. Measure a ring or a finger in under a minute and convert the size to 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 ring size measure.
• 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.
• Between sizes? Mesurix tells you which one to choose, so the ring always passes the knuckle.

EVERY RING SIZE STANDARD

• Instant ring size chart: US/CA, UK/AU, EU/ISO millimetres and Japan — side by side.
• Pick your preferred size standard in settings and switch anytime.
• See the exact inner diameter in mm behind every ring size.

ON-SCREEN RULER

• A real calibrated ruler in mm, cm and inches with a draggable guide line.
• Calibrate once for your exact display — accurate measurement on any phone.
• Copy the measured value with one tap.

BUBBLE LEVEL

• Surface mode: lay the phone flat and level anything with a live x/y bubble level.
• Edge mode: rest the phone on its edge and read the angle in degrees — hang shelves, frames and TVs straight.
• Set zero on any known-flat surface to cancel sensor bias.

SAVE, SHARE, PRINT

• Save ring 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 choosing an engagement ring or wedding band.

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 — Mesurix measures it right the first time.
