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.

Easiest if you have a ring that fits the finger you're shopping for.
- Place your ring over the printed circles, starting with the smallest.
- Stop when the circle's outline sits just inside the ring's inner edge.
- That circle is your size.
Use the ring sizer strip
No ring to measure? The paper strip works just as well.
- Cut out the strip along the dashed line, then cut the slit.
- Wrap it around the base of your finger, printed side out.
- Feed the narrow end through the slit until it feels snug.
- 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.
