The table above provides a Universal Cap Size Chart, covering sizes from junior to adult x-large. It is designed to give you a clear overview of typical cap sizing based on head circumference, with both cm and inches included. This makes it easier to find the right fit across age groups and head shapes when shopping online.
However, please note that sizing can vary slightly between brands, so this chart should be used as a general reference only. If a specific product has a brand-supplied size guide, you’ll find it listed in the product description—we recommend referring to that first for the most accurate fit.
Considering More Than Just Size
In addition to head circumference, it is also important to consider the cap style, material, and intended use. For example:
- Snapback or adjustable caps – Feature straps for flexibility and can fit a wide range of head sizes.
- Fitted caps – Require precise sizing based on head circumference; slightly tighter for a secure fit.
- Sports caps – Often include stretch panels, moisture-wicking fabrics, or ventilation holes for comfort during activity.
- Material – Cotton caps may shrink slightly after washing, while synthetic caps retain shape better.
Choosing the Right Size
- Measure your head circumference accurately using a soft tape measure, wrapping it around the widest part of your head just above the eyebrows and ears.
- If you’re between sizes or unsure, we generally recommend sizing up for added comfort.
- For adjustable caps, use the strap or buckle to fine-tune the fit.
Why This Guide Matters
We know that finding the right cap size can sometimes be a challenge — especially with the wide range of brands and styles available. That’s why we’ve created this comprehensive Cap Size Chart Guide to help you make confident, informed decisions when shopping online with us.
Final Note
This general guide is a helpful starting point, but it’s important to remember that cap sizes can vary slightly between brands and styles. Whenever possible, we strongly recommend checking the brand-specific size guides provided on our product pages for the most accurate fit.
✅ Pro Tips for Measuring Socks
- Measure your head circumference carefully: Wrap a soft tape measure around the widest part of your head, just above the eyebrows and ears.
- Measure twice for accuracy: Take two measurements and use the average to ensure a correct fit.
- Consider hair volume: If you wear thick hairstyles, leave a little extra room to avoid a tight fit.
- Check adjustability: For caps with straps, buckles, or Velcro, adjust them to achieve a snug yet comfortable fit.
- When in doubt, size up slightly: A slightly larger cap is usually more comfortable and easier to wear for extended periods.
Brand-Specific Size Guides
On our website, you’ll find these brand-specific size guides directly under the product description on each product page. These charts are provided by the manufacturers and are the most accurate reference for that particular brand. If a brand-specific guide is listed, we encourage you to follow it rather than relying solely on this general chart.

Fit tips
If you’re on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
How to measure
Measure the circumference of your head using a tape measure. Wrap it around your head at the point where the hat will sit (about an inch/2.5cm above your eyebrows).
