How do I find my ring size at home?

Wrap a strip of paper or string snugly around the base of the finger, mark where it overlaps, and measure the length in millimeters. That number is your inner circumference; match it on our conversion chart to find your US, UK, EU, JP, or HK size.

What if I am between two ring sizes?

Always size up. A ring should slip over the knuckle with light resistance and feel snug at the base. Mirage Garden offers one complimentary resize within 12 months of purchase (±2 sizes) on every ring we make.

Does Mirage Garden ship a free ring sizer?

Yes. Email or WhatsApp us your address and we will send a complimentary plastic ring sizer worldwide.

How to measure

Three reliable methods.

Measure a ring you already wear

Pick a ring that fits the intended finger snugly without sliding off. Place it flat on a ruler and measure the inside diameter from edge to edge in millimetres. Match the number to the “Diameter” column below.

Wrap a strip of paper

Cut a strip of paper roughly 8 cm long and 5 mm wide. Wrap it around the base of the finger, snug but not tight, and mark where the ends meet. Lay it flat and measure in mm — that's your circumference.

Mirage Garden lists ring sizes in US notation. If your local size falls between two rows, choose the larger one.

Small things that matter

A few quiet rules.

—Measure at the end of the day — fingers swell slightly with warmth and use.
—Avoid measuring when your hands are very cold; you'll size down too far.
—If your knuckle is wider than the base of your finger, size for the knuckle and we'll add light beading inside the band.
—Wider bands (3 mm and up) feel tighter — go up by half a size.
