Ring Size Guide
A ring that fits sits snug at the base of the finger and needs a small push to clear the knuckle. Here is how to find that number before you order — and what we do if it's still not right.
Resizing, on us
- Before your ring is made: one free resize before the order is processed — email us the correction.
- After purchase: one free resize per year. Ship the ring to us; we size it and return it at no cost. Allow 1–2 weeks plus shipping.
- Custom sizes — above or below the chart — are available. Ask.
- Have resizing done here, not locally — outside work on the piece ends the warranty on the affected part.
Find your size
Method 1 — measure a ring that fits. Take a ring worn on the same finger, measure the inside diameter edge to edge in millimeters, and read the row.
Method 2 — measure the finger. Wrap a strip of paper snugly around the base of the finger, mark the overlap, measure the length, and use the circumference column.

Method 3 — we mail you a sizer, free. Email appointments@mazalitonyc.com with your name and mailing address and we'll send a ring sizer to measure at home. Or walk in — sizing at the counter takes a minute.
Getting it right
- Measure at the end of the day — fingers swell slightly.
- Not when your hands are very cold or very hot; both move the number.
- Larger knuckle? Size for the knuckle, not the base — a half size up usually does it.
- Your dominant hand runs slightly larger.
