There are two simple ways to figure out your ring size.
If you already have a ring that fits the right finger, measure it directly. If not, measuring your finger works just as well.
METHOD 1: MEASURE YOUR FINGER
-
Cut a strip of paper or string — around 10 cm is enough.
-
Wrap it around the exact spot where the ring will sit. It should feel snug but not tight.
-
Mark where the ends meet.
-
Lay it flat and measure the distance from the starting point to the mark in millimeters (mm).
-
That number is your finger’s circumference.
METHOD 2: MEASURE AN EXISTING RING
-
Pick a ring that already fits the finger you’re shopping for.
-
Measure the inner diameter using a ruler or tape measure. Make sure you’re measuring the inside edge to inside edge.
-
Match the diameter to the size on our Ring Size Chart to find your exact fit.
Additional Tips
Your finger size isn’t fixed — it can shift during the day and with temperature changes.
For the most reliable result, measure your finger later in the day, when your hands tend to be warmer and slightly more relaxed.
If your measurement lands between two sizes, go with the bigger size. It’ll ensure the ring feels comfortable and doesn’t pinch.
