Sizing Guide

 

Use the sizing guide below to choose your Buffr.

For engagement rings, wedding bands, or everyday jewelry, your Buffr should match the inner circumference of the ring you're protecting.  This is our Original Buffr where Ring Size = Buffr Size.

If your ring is thicker or you’re between sizes, we recommend sizing up for a looser fit, or down for a snugger grip.

💡 For smart rings like Oura, RingConn, or Superhuman, just match your exact ring size for the perfect Buffr SMART fit — no guesswork needed in our newly designed product.

***If you are unsure of your ring size, download the JW Ring Sizing App on Apple Store or Google Play Store to measure your rings***
