Measurement Guide

All John Hardy jewelry is artisan-crafted, our pieces are one-of-a-kind and unique. Similar style bracelets are created with different gauges and different materials, which affects their length. Once you have selected a piece, the best way to determine what size to order is by measuring your actual wrist. Please see below for more instructions on how to measure your wrist for bracelets, cuffs, coils, and bangles.


Measuring For Rings

Measure the finger you intend to wear the ring on using a flexible tailor’s tape or a ring sizer.
  • Narrow/Band Rings: Should fit snugly at the base of the finger, but also wide enough to fit the widest part of the finger.
  • Wide Rings: Should be worn a bit looser than narrow/band rings.
  • Coil Rings: May expand or stretch over time.
