Quick answer
To find the right OKC Comets youth cap, measure your child's head circumference just above the ears and eyebrows. Use that measurement to choose between flex fit caps (sized S/M or L/XL) and adjustable caps (one-size-fits-most with a strap). For toddlers, the OKC Comets Home Youth 39/30 White Cap offers a specific toddler size, while the OKC Comets Youth Primary Light Blue Adjustable Cap works well for older kids who need room to grow.
How to measure your child's head for a cap
Use a flexible measuring tape or a piece of string. Wrap it around your child's head about one inch above the eyebrows and just above the ears. Keep the tape snug but not tight. If using string, mark the overlap and measure it against a ruler. Write down the measurement in inches or centimeters.
Most youth caps fit head circumferences between 20 and 22 inches (51 to 56 cm). Toddler sizes typically run smaller, around 18 to 20 inches (46 to 51 cm). Knowing this number is the first step to picking the right cap style.
Flex fit vs. adjustable: what's the difference?
Flex fit caps use a stretchy fabric band that conforms to the head. They come in numbered sizes or ranges like S/M and L/XL. They offer a clean, snug look without a visible strap, but the fit is less forgiving if your child is between sizes. The OKC Comets Home Youth 39/30 White Cap uses Flex Fit construction, making it a good choice for kids whose head size falls squarely within the range.
Adjustable caps have a strap or snap closure at the back. They are more forgiving and can grow with your child. The OKC Comets Youth Primary Light Blue Adjustable Cap and the OKC Baseball Club 405 MVP both use adjustable closures. These are ideal if you want a cap that can be loosened or tightened as your child grows.

Choosing the right cap for your child's age and activity
For toddlers and preschoolers, prioritize a cap that stays put without being too tight. The OKC Comets Home Youth 39/30 White Cap is available in toddler size, which is designed for smaller heads. Its Flex Fit construction provides a secure fit without a bulky strap that could irritate sensitive skin.
For school-age kids who play sports or spend time outdoors, an adjustable cap is often more practical. The OKC Comets Youth Primary Light Blue Adjustable Cap is lightweight and breathable, and the adjustable closure lets you fine-tune the fit for active play. The OKC Baseball Club 405 MVP offers a similar adjustable design with a classic silhouette that works for both games and everyday wear.
When to size up or down
If your child's head measurement falls right at the top of a size range, consider sizing up for room to grow. Adjustable caps are more forgiving here because you can tighten the strap. Flex fit caps have less give, so if you're between sizes, go with the larger size for comfort.
A cap that is too tight can cause headaches or leave red marks. A cap that is too loose will slide down or spin around. The goal is a snug but comfortable fit that stays in place when your child moves.
Decision rules for picking an OKC Comets youth cap
- Measure first, then choose style: Use a flexible tape to measure head circumference just above the ears and eyebrows. Compare to the cap's size range. If you don't have a measurement, adjustable caps are safer because they can be tightened or loosened. Always measure before buying. Adjustable caps offer more leeway.
- Flex fit for toddlers, adjustable for growth spurts: Toddlers often need a cap that stays put without a strap. Flex fit caps like the OKC Comets Home Youth 39/30 White Cap work well. For older kids who are still growing, an adjustable cap like the OKC Comets Youth Primary Light Blue Adjustable Cap gives you room to adjust. Flex fit for stability, adjustable for longevity.
- Consider the activity level: If your child wears the cap for sports or active play, an adjustable cap with a secure closure is less likely to fall off. For casual wear or special game days, a flex fit cap offers a cleaner look. Active kids benefit from adjustable caps. Casual wear works with either style.
