Measure it in a minute

No guessing, no returns you didn’t want. Three honest ways to find your size — and a ruler you can trust before you trust the number.


Ring size

Three ways to measure a ring

Print at 100% (no scaling) on letter paper, then check the ruler below reads exactly its marks before you trust it.

Print the strip sizer

Print at actual size, cut the strip, wrap it around your finger and read where it meets. Calibrate with the ruler below first.

Measure a ring you own

Take a ring that already fits the right finger and measure its inner diameter in millimetres, edge to edge. Match it to the table below.

Wrap paper and mark it

Wrap a thin strip of paper snugly around the base of your finger, mark where it overlaps, then measure that length — the inner circumference.

Calibrate first Printed at 100%, this bar measures exactly 100 mm (10 cm). If a ruler laid against your print disagrees, set your printer to “Actual size / 100% / no scaling” and print again.

A steadier fit

Between sizes? Size up. Measure at the end of the day, when fingers are largest, and take the reading two or three times. Cold hands read small.

Necklace length

Where each length falls

Choker · 14″
Sits high, close around the base of the neck.
Princess · 18″
The everyday drop, resting just below the collarbone.
Matinee · 20–24″
Falls onto the chest — layer it or wear it long.
Bracelet

A comfortable wrist

Wrap a strip of paper around your wrist where the bracelet will sit, mark the overlap, and measure it. Then add a finger’s width for ease so it moves without sliding off.
