How to Measure for a Child Safety Helmet:
- Measure Head Circumference:
- Use a soft measuring tape (like the one used for sewing) to measure around the widest part of the child’s head, about 1 inch above their eyebrows and ears.
- Make sure the tape is snug but not tight.
- Match the Measurement to the Chart:
- Once you have the circumference measurement, compare it with the chart above to find the appropriate size.
- Check the Fit:
- The helmet should fit snugly around the child’s head without being uncomfortable.
- When the helmet is properly adjusted, it should not move around or slide off easily.
- If the helmet has a dial or adjustable straps, use those to fine-tune the fit.
