Measure circumference with paper
StepsYou need: a paper strip (about 5 mm wide), a ruler marked in millimetres, and a pen.
-
Mark the circumference
Wrap the paper strip snugly around the base of your finger where the ring will sit. Mark exactly where the paper overlaps with a thin, precise line.
-
Measure the length
Lay the paper strip completely flat on a table. Use the ruler to measure the distance from the start of the paper to your mark in millimetres.
-
Find your size
The number of millimetres you measured in step 2 is your exact ring size. If you measured 54 mm on the ruler, for example, your size is 54 on the EU scale.
-
Check accuracy
Repeat the process 2–3 times to make sure the measurement is accurate. Use the average of your measurements for the best fit.
