Turkey Ring Size Chart
Compare Turkey ring sizes with US, UK, and metric measurements.
Turkey size equals circumference minus 40
For example, an inner circumference of 54 mm corresponds to Turkey size 14.
Two Turkish jewelers publish this same relationship. To find a Turkey size from a measurement, subtract 40 from the ring's inner circumference in millimeters. Always confirm the retailer's current guide before buying, especially for wide bands.

Frequently asked questions
How does the Turkish ring size system work?
Turkish size equals the inside circumference in millimeters minus 40: a 52 mm circumference is about a Turkish size 12. Two Turkish jewelers publish the same relationship independently, which is why this system carries a verified rating here.
Is the Turkish system the same as Indian sizing?
Numerically it matches the corroborated Bluestone/Jewelove India convention (also circumference minus 40), but it is exposed separately because Turkish sources identify it as Turkey’s local system. Same arithmetic, different provenance — use the column that matches where you are buying.
How do I convert my Turkish size to US or UK?
Find your Turkish number in the table and read across to the US, UK, EU, Germany, and Japan columns — every row shares one millimeter anchor, so all equivalents describe the same physical ring.
What if my measurement falls between two Turkish sizes?
Turkish sizes move in whole numbers, so between-measurements are common. As a rule of thumb, thinner bands sit comfortably in the smaller size while wide bands (6 mm+) usually want the larger one — and the ring size calculator will show you both neighbors.
