Find your perfect fit

Measure your ring size at home in minutes with our printable ring sizer and conversion chart.

How to measure your ring size

A good fit is snug enough to stay put, loose enough to slide over your knuckle. Print our ring sizer on A4 paper at 100% scale (no "fit to page") and check the 5cm line with a ruler, then choose a method below.

Method 1

Use a ring you already own

Easiest if you have a ring that fits the finger you're shopping for.

  1. Place your ring over the printed circles, starting with the smallest.
  2. Stop when the circle's outline sits just inside the ring's inner edge.
  3. That circle is your size.
Method 2

Use the ring sizer strip

No ring to measure? The paper strip works just as well.

  1. Cut out the strip along the dashed line, then cut the slit.
  2. Wrap it around the base of your finger, printed side out.
  3. Feed the narrow end through the slit until it feels snug.
  4. Read the size where the strip meets the slit.

Between sizes? Choose the larger size.

Best time to measure: at the end of the day, when fingers are warm. Cold fingers read smaller.

Wide band? Bands 6mm and wider fit tighter, so consider going up half a size.
