Before you cut

This line measures exactly 100 mm. If a ruler says otherwise, print again at 100%, with scaling switched off.

1. 1Cut out the strip along the dashes, and cut open the slot.
2. 2Wrap it around the base of your finger and feed the pointed end through the slot.
3. 3Pull it snug, not tight, and read the size at the slot.

Measure at the end of the day, when fingers are at their largest, and warm.
A ring should pass the knuckle with a little resistance.

Or measure a ring you own, straight across the inside, in millimetres
