How to Choose Your Size

Measure Your Finger 

(String or Paper Strip)

Step 1:
Wrap a thin strip of paper or string snugly around the base of the finger you'll wear your ring on. Mark where the ends overlap.

Step 2:
Lay the strip flat and measure its length with a ruler. Then match your number to the chart below.

Size 6

57 - 59 mm

Size 7

60 - 62 mm

Size 8

63 - 64 mm

Size 9

65 - 67 mm

Size 10

68 - 70 mm

Size 11

71 - 73 mm

Size 12

74 - 76 mm

Size 13

76 - 78 mm

Note: These measurements reflect your finger's actual circumference — they may vary slightly from official ring sizing charts, since they're based on how your finger is measured in real life, not a rigid metal band.

Pro Tip: If you fall between two sizes, size up — this ensures comfort for all-day wear.

Question

Good to know.

How accurate is Luna really?

Aurae reads from the palm-side arteries, where the signal is strongest. In independent testing, sleep-stage and heart-rate accuracy track within a few percent of clinical polysomnography and ECG.

Is there a subscription?

No. Every core insight — sleep, readiness, recovery, and trends — is included for life when you buy the ring. We offer optional human coaching as an add-on, but you never need it to get full value.

How do I find my size?

Please read our size chart guide, then choose the size that best fits you.

If you accidentally choose the wrong size, don't worry, we have a free exchange policy for the first time if you choose the wrong size.

What's your return policy?

Try Luna for 30 nights. If it's not for you, send it back for a full refund — no questions, free return shipping included.
