How to Choose the Right Hat Size?
By LogoSportswear | Updated on August 1, 2025
Do all hats come in a one-size-fits-all or do they come in multiple sizes?
Quick answer: Nope! The truth is, some hats may be marketed to fit most heads, but that's not always the case. Heads come in various shapes and sizes, which is why other hats are also available in multiple sizes.
But let's be real — finding the best fit can be quite confusing. Whether you're designing custom hats for your brand, gearing up a sports team, or buying one for yourself, you've probably wondered: Would any size do? How do I choose the right one?
Don't worry, you're not alone. In this article, LogoSportswear explains how hat sizing works and how to measure your hat size so you can find the perfect fit for your needs.
What Does One-Size-Fits-Most Mean?
One-size-fits-most (OSFM) hats have adjustable features like snapbacks, Velcro straps, or buckle backs that allow them to fit a wide range of head sizes. They're the go-to choice for custom hats because they're simple, budget-friendly, and don't take a lot of time to produce.
It's not surprising that most people assume that hats only come in one size because OSFM hats are seen everywhere. You'll see them in mass market retail, branded merchandise, corporate uniforms, and sports team apparel. They are mass-produced for convenience, and they make the buying process and inventory less complex. OSFM hats are suitable for promotions, giveaways, group events, and large orders because you won't have to worry about head sizes. However, if you have a small or large head, they might not work.
Examples of OSFM Hats and Some LogoSportswear Bestsellers
- Trucker hats - Custom Richardson 112 - Trucker Snapback Cap
- Dad hats - Apollo Lightweight Brushed Cotton Twill Hat
- Beanies - Sportsman 12 Inch Knit Beanie
- Visors with Velcro straps - Apollo Brushed Cotton Twill Sandwich Visor
What Does Multiple Sizing Mean?
When it comes to hats, multiple sizing means hats come in sizes like small, medium, large, XL, and sometimes XXL. While OSFM hats are common, multiple sizing is essential in situations where fit, function, style, and sizing matter the most. This includes fashion-forward brands that want the same design in men's, women's, and kids' sizes, family or matching group outfits, personalized gifts, and high-end custom orders.

How to Get Your Hat Size Correctly
Finding your hat size is simple and easy. Just follow these steps to get started:
- Wrap the measuring tape around your head and place it about 1/8” above your ears and eyebrows, across your forehead.
- Ensure that the tape is snug but not too tight.
- Note the measurement in inches or centimeters.
- Compare your measurement to the sizing charts above or on the product pages to find the best fit.
Tip: If you're between sizes, always opt for the larger size. You can choose to add hat tape, or a band insert to make the fit tighter. You can also just go for adjustable hats for a better fit.
Conclusion
So, are hats one-size-fits-all? Not quite. While it may seem that hats only have one generic size, the truth is that it depends on the style and product. Some hats are One-Size-Fits-Most (OSFM), while some come in multiple sizes. OSFM hats are best for large orders, branded merch, and promos because they're budget-friendly, easy to produce, and work for many people. On the other hand, hats with multiple sizes are recommended for high-end custom orders, personalized gifts, or when a better fit is needed.
When choosing a custom hat for your brand, team, or employees, consider picking ones with more inclusive sizes. After all, not everyone has the same head shape or the same level of comfort. With the help of the sizing guides and measurement steps in this article, we hope you now have a better understanding of how hat sizing works.
