Ring Size Chart in Inches

The full conversion chart with every measurement shown in inches, for anyone measuring with a US-style ruler or tape measure.

Measuring in inches

Most household rulers and tape measures in the US show inches, not millimeters.

If you measured a ring or a paper strip against an inch ruler, this chart lets you match that reading directly, down to a thousandth of an inch, without converting to millimeters yourself first.

Have a specific measurement in inches?

Enter it directly and skip scanning the table — the calculator is preset to inches below.

How would you like to find your size?

Measure the inside diameter of the ring — straight across the inner hole, not the outside of the band.

Lay the ring flat and measure straight across the inside edge.
