Measure your finger with a strip of paper or a piece of string.

Step 1. Wrap the strip snugly around the base of the finger you will wear the ring on, and mark where the ends overlap.

Step 2. Lay the strip flat, measure its length with a ruler, then match your number to the chart below.
SizeFinger circumference
657 – 60 mm
760 – 63 mm
863 – 65 mm
965 – 68 mm
1068 – 71 mm
1171 – 74 mm
1274 – 76 mm
1376 – 79 mm

If your measurement falls exactly on the boundary between two sizes, choose the larger size.

These numbers are your finger's actual circumference, so they can differ slightly from official ring charts, which are based on a rigid metal band.

If the size still is not right, your first exchange is free.
Illustrated ring size guide: wrap a thin strip around your finger, measure its length with a ruler, then match the millimetres to a ring size.

Question

Good to know.

How accurate is Luna really?

Luna reads from the palm-side arteries, where the signal is strongest. It's built to give you reliable day-to-day trends for sleep, heart rate, and activity — think of it as a personal wellness tracker, not a medical device.

Is there a subscription?

No. Every core insight — sleep, readiness, recovery, and trends — is included for life when you buy the ring.

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.

Shipping Information

Processing time: 1–2 business days.
Shipping time: 5–7 business days.
We offer a stress-free 30-day return policy — if you're not completely happy, you can return your ring within 30 days.

How do I connect the ring to an app?

Luna Ring works with popular smart-ring apps on iOS and Android — like QRing and LuckRing. Setup takes about a minute:

1. On your phone, turn on Bluetooth.
2. Download QRing (or LuckRing) and open its device-pairing settings.
3. Place your fully-charged ring next to your phone to pair.

Once connected, your sleep, heart rate, and activity sync automatically each day.

Sleep better. Wake up knowing.

Try Luna risk-free for 30 nights. If it's not for you, send it back.
