Football Mouthguard Sizes: Adult vs Youth CHD Guide

September 30, 2026

Choosing between Adult and Youth football mouthguards starts with the dimensions of the specific model. CHD graphic mouthguards use the same shell structure in two sizes; the dimensions differ. The age ranges shown on CHD product pages are suggestions, so compare the measurements and check individual fit before ordering.

Angled product view of the CHD Black Cookie design football mouthguard — CHD Black Cookie design mouthguard. This product currently lists both Adult and Youth options.

What are the CHD Adult and Youth dimensions?

CHD graphic mouthguard	Width	Height	Lower-edge width
Adult	70.8 mm	55.4 mm	66.9 mm
Youth	62.6 mm	51.1 mm	52.8 mm

These are the measurements published for CHD's Black Cookie design mouthguard and Cow Print design mouthguard. Measurements are taken manually, with a stated tolerance of ±1 mm. They describe those CHD products, not every football mouthguard on the market.

Is age enough to choose a size?

No. CHD labels Adult as suggested for ages 12 and up and Youth for under 12, but the product page says age is only a guide. Check the dimensions and the player's individual fit. If you are collecting a team order, ask each player or parent to confirm the selected option rather than assigning every player in an age group the same size.

Does every CHD design offer both sizes?

Check the size selector on the exact product page. Black Cookie and Cow Print currently list both Adult and Youth. Other styles can have a different size range. A photo may show the artwork clearly, but it is not a scale drawing and cannot confirm fit.

What should you check before adding to cart?

Open the product page for the exact design you want.
Confirm that Adult or Youth appears in its current size selector.
Compare the listed dimensions with the intended wearer and check individual fit.
For several players, record design and size beside each name before checkout.

CHD's graphic product pages also describe what comes in the box and how to care for the item. Review those instructions for the selected design. For a closer look at the artwork, see the Cow Print mouthguard photo story.
