Wrap a thin strip of paper or string around your finger at the knuckle.

Mark where the paper meets and measure the length in mm — this is your circumference.

📏 How to Measure Your Ankle
1
Sit down and rest your foot flat on the floor.

Wrap a flexible measuring tape around the narrowest part of your ankle, just above the ankle bone.

Note the measurement in cm. Add 2–3 cm for a relaxed draping fit, or 1 cm for a snug fit.
Tip: Most anklets look best with 2–3 cm of extra room so they can move freely when you walk. Measure both ankles — they can differ slightly.
