Method 1 — Use a Ring You Already Own (Most Accurate)

1. If you already know the size of a ring that fits you comfortably, simply let us know that size.

If you don't know the size of your existing ring, follow Method 2 to measure the inner diameter.

Method 2 — Measure the Inner Diameter of an Existing Ring

Place your ring flat on a ruler and measure the inner diameter straight across the center (in mm).
Match your measurement to the table below to find your US size.

Method 4 — Measure with a Strip of Paper (Least Accurate)

Cut a strip of paper no wider than 5 mm.
Wrap it around the base of your finger, mark where it overlaps, then unwrap and measure the length (mm).
Per our guide: Subtract 2 mm from your measurement to account for paper thickness, then match to the table below.

Measure ring size by wrapping a paper strip no wider than 5mm around the finger and marking the overlap — Wrap paper ≤5 mm around your finger, mark the overlap, then measure in millimeters

Important tips for the paper method:

Paper wider than 5 mm → your measurement will read larger than your actual size
Fabric tape measure (wide) → can cause inaccurate readings
String or thread → stretches and contracts under tension, leading to errors
If you have large knuckles → measure at the knuckle so the ring can slide on, but note the ring may feel slightly loose at the base of your finger
