Free sizing kit

A ring is only accurate if it fits.

Seven plastic sizers, US 7 to 13, in a box the size of a coaster. Wear the closest one for a full day and night, then order your ring in that size.

Order the kit

The kit is free and ships by tracked post. Nothing is charged, and no ring order is created until you confirm a size in the app.

The sizing kit is temporarily unavailable.

Caution

Fingers change size by up to half a step between morning and night. Test across both.

Fingers are largest in the evening. Pick the sizer that slides over the knuckle with slight resistance.

If you wake up and it has moved or spun freely, go down one size the next night.

Cold morning fingers are smallest. The sizer should still not fall off when you shake your hand.

Choose the size printed inside the sizer when you order your ring.
