## What is True Ring Size?

Find your ring size in seconds — no physical sizer needed.
True Ring Size turns your phone into an accurate ring sizer that works fully offline.

Two ways to measure:
• Ring on screen — place a ring you already own on the display and resize the circle until it matches.
• Finger on screen — line up the guides to your finger and read the size instantly.

Calibrate once with any bank card for real-millimeter accuracy, then convert between US, UK, EU, Japan, China and Russia sizing — by diameter or circumference, in mm or inches.

Why True Ring Size:
• 100% offline — no internet permission, nothing leaves your phone
• Free forever — no subscription, no in-app purchases
• No ads, ever
• No account, no tracking, no data collection
• Save sizes for the whole family — perfect for surprise gifts and engagement rings
• Full conversion chart for every country system

Whether you are buying an engagement ring, a wedding band, or a gift, True Ring Size helps you order the right size online with confidence.

Note: on-screen measuring depends on your screen; calibrate with a card and measure twice for best results.
