Wrap a soft tape measure around your child's head about 1cm above their ears and eyebrows, where a hat would sit. Keep the tape level and snug but not too tight. This gives you their head circumference.
Most 5-year-olds have a head circumference of about 50-52cm (19.5-20.5 inches), which corresponds to size S or M in kids' hats. However, always measure for the best fit as children's head sizes vary.
If between sizes, sizing up slightly is a good idea since children grow quickly. Many kids' hats also have adjustable straps that accommodate growth and provide a better fit.
