Size Measuring Tips

STEP 1
Take a long, non-elastic piece of rope or strip of paper and wrap it around the finger you want to size.

STEP 2
Ensure the rope or paper fits snugly — not too tight and not too loose — to avoid inaccurate measurements.

STEP 3
Mark the point where the rope or paper overlaps (the junction).

STEP 4
Lay the marked rope or paper flat and measure the length between the marks using a ruler. It's advised to measure multiple times for better accuracy.
