Try every size at home, then we make yours.

Every size of Aina Ring has the same screen. A bigger size isn’t a bigger screen, just a wider band, to fit your finger. Turn the dial to see all 7.

   Order

   Your ring is made and ships

   Your Aina Ring is made in that size, and it ships in early 2027.

1. 01

   Try the sizers on your index finger

   Fingers can differ from hand to hand, so try both. Early users preferred their non-dominant hand. Whichever you choose, turn the sizer so its top faces your thumb.

2. 02

   Check the fit

   Once a size feels comfortable, flick your thumb across its top. The sizer shouldn’t shift on your finger as you do.

3. 03

   Wear it for a day

   Wear that size for at least a day, and go about it as usual. You’re looking for a snug, secure fit that stays comfortable throughout. You can take it off to sleep.

Yours to keep, with nothing to send back

Aina Ring should feel snug, not tight. It shouldn’t turn on your finger as you move your hand, and it should stay comfortable through a normal day.

• Between two sizes? Go with the smaller one.
• Try sizes later in the day. Fingers are a little larger in the evening than in the morning.
• Try them at room temperature. Fingers shrink in the cold and swell in the heat.
• Mind the knuckle. The right size slides over it with a little resistance, then sits snug below it.

If no size feels right, tell us in the Aina app and we’ll sort it out with you.

If your ring doesn’t fit when it arrives, you can exchange it for another size within 14 days of delivery, at no cost. Write to team@aina.com with your order number and the size you need. The full terms are on the shipping and returns page.
