Find Your Perfect Ring Size

Printable Ring Sizer

The most accurate at-home method. Print our ring sizer at 100% scale (do not scale to fit page), cut it out, and slip it onto your finger. The tab locks at your exact size.

Print at 100% scale — do not use "fit to page". Check the scale bar on the sheet measures exactly 50 mm before cutting.

Wrap-String Method

Works with a thin strip of paper, dental floss, or non-stretch string. Measure in the evening when fingers are at their largest.

1. 1.Wrap a thin strip of paper or non-stretch string around the base of the finger you want to size — the point where the ring would sit.
2. 2.Mark the point where the paper or string meets itself with a pen.
3. 3.Lay it flat and measure the length in millimetres with a ruler. This is your finger circumference.
4. 4.Find your AU size in the EU column of the size chart below — the EU value is the inner circumference in mm.
5. 5.If you land between two sizes, always size up for comfort.

If you have a ring that fits perfectly, measure its inside diameter and look it up in the Diameter column of the size chart below.

2. 2.Measure across the widest internal point — from one inside edge to the opposite inside edge.
3. 3.Note the measurement in millimetres.
4. 4.Find the matching row in the Diameter (mm) column of the size chart below.
