How to Measure Your Head
- Use a soft tape measure (or a piece of string measured against a ruler).
- Wrap it around your head approximately 2.5 cm (1 inch) above your eyebrows and level across the back.
- Keep the tape snug but not tight.
- Record the measurement in centimetres. If between two sizes, select the larger size for comfort.
