Three ways to find your size

Use a ring that already fits. Print our ring sizer at 100% and lay the ring on the circles. Your size is the circle that matches the inside edge exactly.
Measure your finger. Cut out the paper strip on the sizer, wrap it around the base of your finger and read your size at the slit.
Measure a ring with a ruler. Measure straight across the inside of the ring, edge to edge, and match the inside diameter in the table.

Buying a gift?

Borrow a ring they already wear on the same finger, for an evening, and measure it with method 1 or 3. If you can't, the most common women's sizes are around UK L to N, and a gift card is always the right size.

Tips

Measure at the end of the day, when your fingers are warm. Cold fingers are smaller.
Between two sizes? Choose the larger.
Wider bands, like our Greek Key and Three Band rings, fit a little snugger, so go up half a size if you're in doubt.
The ring needs to slide over your knuckle, so check that too.

Necklaces

As a guide to where each length sits:

Length	Where it sits	Best for
40 cm	Base of the neck	Fine chains, small pendants, the top layer
45 cm	On the collarbone	Your everyday pendant
50 cm	Just below the collarbone	Chunkier chains, the bottom layer
60 cm	Mid-chest	Over a jumper or high neckline

Layering? Leave about 5 cm between each chain so they sit apart.

Bracelets

Wrap a strip of paper around your wrist bone, mark where it meets, and measure it flat. Add 1 to 2 cm for a comfortable fit.

Your wrist	Bracelet length
14 to 15 cm	16 cm
15 to 16.5 cm	17.5 cm
16.5 to 18 cm	19 cm

Chain bracelets with an extender adjust between sizes. Our woven hair bands stretch to fit almost every wrist.

Earrings

Diameter	Style
8 to 10 mm	Huggie: hugs the lobe, great for second and third piercings
12 mm	Classic huggie, the everyday size
15 to 20 mm	Small hoop
25 mm and up	Statement hoop
