1. Wrap the measuring tape or paper snugly around the thinnest part of your wrist. Ensure the measuring tool fits comfortably without being too tight or too loose.

2. If you're using a measuring tape, note the measurement where the end of the tape overlaps. If you're using a strip of paper, mark or cut the paper at the point where it wraps fully around your wrist.

3. For a regular fit: Add 0.5-1.0 cm to your wrist measurement. For a slightly loose fit: Add 1.0-1.5 cm to your wrist measurement.
