The National Highway Traffic Safety Administration has some clear-cut tips for making sure the helmet fits.

The bike helmet should sit level on the head and low on the forehead, which means about one or two finger-widths above the eyebrows.The chin strap should be snug, so nothing more than a finger can fit under it.To make sure the helmet fits correctly, have your kid yawn wide. If the helmet does not pull down on his or her head, you need to tighten the chin strap.If the helmet rocks back two or more finger-widths above the eyebrows, you need to shorten the front strap. If the helmet rocks forward into the eyes, the back strap needs to be tightened.

But a helmet’s protection is only as good as its construction, and two organizations — the Consumer Product Safety Commission (CPSC) and American Society for Testing and Materials (ASTM) — work to ensure helmets’ components are ready to protect. Always look for at least one certification before purchasing a kids helmet. All the below helmets, for both boys and girls, pass that test. As for which helmet, well, the rest is up to you and your child. If you opt for a basic design but your kid wants something wilder (or sillier), helmet covers offer a cool compromise.
