Kids Hat Size chart

Fit is so important when it comes to picking a child's hat. Especially as all Hotdogs heads are different. The sizes are written in AGE but we’ve also included the centimetre measurement. Please make sure you take a moment and check your Hotdog's CM (centimetre) measurement before ordering. 

How to measure: 1, 2, 3 steps

1. Get a fabric tape measure with CM markings, or a strip of paper or fabric.

2. Wrap the tape measure or fabric around your Hodog’s head, sitting just above the ears.

Make sure the tape measure is not tight and has some movement.

3. Round UP to the nearest cm.

Check the chart if your Hotdog is between sizes go up to the next size.
