Find Your Ring Size

Use a ring that already fits or measure your finger to find the closest Stonex ring size.

Measure an existing ring

Choose a ring that fits the intended finger.
Measure its inside diameter across the widest point.
Match the diameter in millimetres to the chart.

Measure your finger

Wrap a non-stretch paper strip around the finger.
Mark where the ends meet.
Measure the length in millimetres.
Match it to the inside-circumference column.
Measure near the end of the day, and avoid unusually hot or cold fingers.

This chart helps estimate fit. US sizes are the closest equivalent, and sizing can vary slightly with a ring’s width and design.

Band width: Wider bands can feel tighter than fine bands. If you are between sizes, you may need the next available size.

Find Your Length

Measure a chain that sits where you like it, or use the guide below to choose a length.

Measure a chain you own

Lay a chain that fits flat and straight.
Measure end to end, including the clasp.
Match the length in centimetres to the chart.

Measure on yourself

Wrap a soft tape or a string where you want it to sit.
Mark the spot and measure it in centimetres.
For a pendant, a little extra length lets it sit lower.

Chain & necklace lengths
Length (cm)	Inches	Where it sits
40	16"	Choker — base of the neck
45	18"	Princess — most popular; on the collarbone
50	20"	Matinee — just below the collarbone
55	22"	Matinee — upper neckline
60	24"	Opera — mid-chest, over clothing
70	28"	Long — below the bust

Inches are approximate. Where a necklace sits varies with height and build.
