How To Measure

Measure Your Finger

Wrap a thin paper strip or thread around the finger, mark the overlap point, then measure the total length in millimetres. This gives your finger circumference.

Measure An Existing Ring

Take a ring that already fits well and measure its inside diameter in millimetres. Match it with the chart below for the correct size.

Important: For printable ring sizing guides, keep print/zoom at 100% for better accuracy.

Find Size By Diameter

Enter inner ring diameter in millimetres to detect the nearest Indian and international size.

Diameter (mm)

Try 16.90 mm

Find Size By Circumference

Enter finger circumference in millimetres to detect the nearest matching size.

Circumference (mm)

Try 53.10 mm

Visual Ring Diameter Preview

These circles show relative inside-diameter growth from smaller to larger ring sizes.

Best time to measure Measure towards the end of the day for a more comfortable fit.

Check knuckle size If your knuckle is larger, choose a size that can pass comfortably.

Wide band rings For broader bands, choosing one step larger often feels better.
