Football helmet guide: fit, chin strap, NOCSAE and the 10-year rule

Quick answerThe CDC says no helmet is concussion-proof, but a football helmet can help protect against a serious brain or head injury. Measure the head with a soft tape just above the eyebrows and ears, then use the maker's sizing chart. The helmet should feel snug with no spaces under the pads and should not slide or come off with the chin strap in place. The chin strap should be centered and snug; when the player opens wide, the helmet should pull down. Look for a label saying it meets the NOCSAE standard, and replace a football helmet no later than 10 years from its date of manufacture.

Sizing before you buy

Chin straps and air bladders

The chin strap is a big part of football helmet fit. The CDC's yawn test: have the athlete open their mouth wide, and the helmet should pull down on the head; if it does not, tighten the chin strap. On helmets with a four-point chin strap, all four straps must be snapped and tightened during fitting.

Some helmets use a special fitting system or air bladders that are inflated with a special needle so the bladders are not punctured. For bladder-equipped helmets, the CDC says to check for proper inflation. Make sure you can see the athlete's eyes and that they can see straight ahead and to the sides.

NOCSAE labels and standards

The CDC says to look for a football helmet with labels that:

NOCSAE lists ND002 as its standard for newly manufactured football helmets, ND004 for recertified football helmets and ND087 for football faceguards. It also lists ND006, a proposed standard for newly manufactured youth football helmets.

Reconditioning and the 10-year rule

Reconditioning means an expert inspects and repairs a used helmet, replaces missing parts, tests it and recertifies it. The CDC says helmets should be serviced regularly by a licensed NAERA member, and not to let an athlete use a used helmet that has not been recently recertified. It notes only companies licensed by NOCSAE can recertify a helmet.

The CDC's "10 and out" rule: football helmets should be replaced no later than 10 years from the date of manufacture, and many will need replacing sooner because of wear and tear. Check the date label on any used or hand-me-down helmet before it goes on a player's head.

Care, storage and damage

The CDC also says there is no concussion-proof helmet. For other gear, see our youth football size guide and batting helmet guide.

When to talk to a doctor: Remove any athlete with a suspected head injury from play and have them checked by a health care provider before returning. No helmet is concussion-proof.
