Measure your ring size

Planning a proposal or buying a ring for yourself? Here are five reliable ways to measure ring size.

How to measure your ring size

Find your size

Measure a Ring That Already Fits

Place the ring on a flat surface or ruler.
Measure straight across the centre of the inside circle
Measure in millimetres
Compare the diameter with a ring size chart.
Make sure the ring is worn on the same finger the new ring is for.

Use a Plastic Ring Sizer Tool

Slide the sizer onto your finger.
Tighten it until it feels snug but comfortable.
Make sure it slides over the knuckle with slight resistance.
Check it sits securely at the base without spinning.
Read the indicated size on the tool.

String or Paper Strip Method

Wrap a string or paper strip around the base of your finger.
Mark where the ends meet.
Lay it flat and measure the length in millimetres.
Compare the measurement with a ring size chart.
Avoid pulling too tight — this method is a rough estimate only.

Printable Ring Size Chart

Print the ring size chart at 100% scale.
Place your ring over the printed circles.
Find the circle that fits perfectly inside the band.
Ensure there are no gaps or overlaps.
Use a ring worn on the correct finger for accuracy.
