Football helmet sizing is a safety measurement, not a style preference. The only valid starting point is head circumference — measured with a soft tape around the widest part of the head, level above the eyebrows and around the ears. Age-based sizing should not be used for helmet selection because head size varies widely among players of the same age. Two 10-year-olds can easily measure into different helmet size ranges.

After you have the circumference measurement, find the official chart for the specific brand and model you are buying. Helmet shells, padding systems, and adjustment mechanisms vary enough between brands that a general guide cannot tell you which size is right. For youth players in organized leagues, a certified fitter or equipment manager can verify the fit, and getting that second check is worth the time for a piece of protective gear worn every practice and game.

Editorial note

We use these guides as starting ranges, then compare the recommendation against brand charts, fit checks, and sport-specific safety rules before surfacing gear links. Read more about how our sizing works.

SmallUp to 20 3/8 inIf between listed sizes, Riddell says to start with the smaller size.
Medium20 3/8-22 inConfirm helmet height, crown pressure, and pad contact.

X-Large23 1/2 in and upHave the adjusted fit verified before play.

Source context: The displayed ranges are Riddell's official SpeedFlex Youth chart. They do not transfer to Schutt, Xenith, other Riddell models, or a different padding system; use the exact model chart and complete its physical fit process.

Points to measure

Football helmet measuring path

Start with head circumference, then verify the exact model with a fitter or coach.

  1. 1ForeheadMeasure above the eyebrows.
  2. 2Widest pointKeep tape level around the head.
  3. 3Fit checkHelmet should sit level and secure.
  1. 1Wrap a cloth tape around the widest part of the head, approximately one inch above the eyebrows. Keep the tape level and record the number.
  2. 2Open the chart for the exact brand and model. The table above is specifically for the Riddell SpeedFlex Youth, not a universal football helmet chart.
  3. 3Position the front edge about one inch above the eyebrows and adjust only according to the manufacturer's fitting instructions.
  4. 4Confirm snug crown, side, back, and jaw contact; the forehead skin should move with the front pad when the helmet turns.
  5. 5Have the final fit checked by the league's equipment manager, coach, athletic trainer, or qualified fitter before play.

Good reasons

When to size up

  • Your child is between sizes and the larger size still feels controlled.
  • The season is several months long and the gear is not protective headgear.
  • The brand chart says the current measurement is at the top of a range.

Avoid these

Common mistakes

  • Buying only for growth and making the gear hard to control.
  • Skipping the brand chart because another brand fit last season.
  • Ignoring league rules for bats, balls, sticks, and protective equipment.

Parent tip

Avoid used helmets unless age, condition, certification status, and safety history can be verified.

FAQ

How do I measure my child's head for a football helmet?

Wrap a soft tape around the head about one inch above the eyebrows, keeping it level over the widest point at the back. Record the number in inches and centimeters, then match it to the exact helmet model's chart — youth shells from different brands fit differently at the same measurement.

What size football helmet does a 10-year-old need?

There is no reliable age-based answer — two 10-year-olds can be two shell sizes apart. Measure head circumference, use the brand's model chart, and have a coach or fitter verify the fit after adjustment. Age never decides helmet size.

What is the youth SpeedFlex helmet size chart?

Riddell lists SpeedFlex Youth Small up to 20 3/8 inches, Medium from 20 3/8 to 22 inches, Large from 22 to 23 1/2 inches, and X-Large from 23 1/2 inches and up. Treat those as starting ranges and complete the model's fitting process.

Does the new NOCSAE youth helmet standard make my current helmet illegal?

Not automatically. Riddell says helmets purchased before the youth ND006 standard's September 1, 2027 effective date can continue under the previous standard for their service life when properly maintained, reconditioned, and recertified. Your league decides which standard its rules require.
