About this app

Orion - Ring Sizer is a practical and intuitive tool designed to help you estimate a ring size directly from your phone. Whether you are buying a wedding band, choosing an engagement ring, preparing a special gift, or checking the size of a ring you already own, Orion makes the process easier.

💍 FIND YOUR RING SIZE

Place a ring on your device screen and adjust the measuring circle until it matches the ring’s inner diameter. Based on this comparison, the app provides a useful measurement reference to help you choose a size.

The process is designed to be visual, quick, and easy to understand, even if you have never used a ring sizing tool before.

✨ SIMPLE MEASUREMENT

Increase or decrease the circle directly on the screen until it closely matches the ring being used as a reference. Information is displayed clearly to make checking the measurement easier.

💎 USE ORION TO:

• Check the size of a ring you already own
• Help choose rings and wedding bands
• Get a reference before buying jewelry online
• Prepare gifts and surprises

🛍️ MORE CONVENIENT ONLINE SHOPPING

Choosing the correct size is one of the biggest concerns when buying rings online. By using a ring that already fits as a reference, Orion helps you obtain a size indication before choosing your ring size.

🌟 EASY TO USE

Open Orion, access the ring sizer, place the ring over the indicated area, adjust the circle until it matches the inner edge of the ring, and check the displayed measurement.

⚠️ IMPORTANT

Orion is an assisting measurement tool. Accuracy may vary depending on screen size and calibration, ring positioning, and how the measurement is performed.

For expensive purchases, wedding bands, custom rings, or situations requiring greater precision, we recommend confirming the final size with a jeweler or using an appropriate physical ring sizing tool.

Keep a practical ring measurement tool on your phone with Orion - Ring Sizer.
