Caps for Big Heads: The 2026 Buyer's Guide
Share
By Dominik, founder of Head of Wonder · Published · Last reviewed
If you've spent years pulling caps off in shops because they sit on top of your head instead of around it, this guide is for you. I'm Dominik, and I started Head of Wonder for exactly the same reason. My head sits at 62 cm, standard caps max out somewhere near 58 cm, and the gap between those two numbers is where most of us live without anyone in the industry seeming to notice.
This is the cornerstone reference I wish I'd had when I was searching. It covers what makes a cap actually fit a bigger head, how the four cap styles we make differ, how to measure yourself in two minutes, and how to tell whether the cap you ordered is the right one when it arrives. Everything here comes from our own catalogue and from running the shop day to day.
If you searched "caps for big heads" or "62 cm cap," you're at the centre of the 60–63 cm range our XL caps are built for. Read on, or skip to the full collection of XL caps when you've got your measurement.
Quick answer
A cap for a big head is one shaped from the start for circumferences between 60 and 63 cm, not a standard cap stretched at the strap. If you measure 62 cm, you sit at the centre of the range Head of Wonder designs around. I'm Dominik, and I built this brand because I spent years buying caps that pinched the temples, rode up on the crown, or wouldn't close at the back. Our XL caps have a deeper crown that wraps around the head, a wider internal band built around 61 cm, and a longer strap that actually closes cleanly anywhere across the 60–63 cm range.
Key takeaways
- Head of Wonder XL caps fit head circumferences from 60 to 63 cm, with the internal band built around 61 cm.
- Standard "one size fits all" caps usually max out near 58 cm, which is why they sit on top of bigger heads instead of around them.
- The current range covers four cap styles: baseball cap, classic trucker hat, dad hat, and snapback.
- We ship 15 cap colours across the range, priced from 649 to 775 CZK.
- The black minimalist classic trucker is our first and only cap in XXL, fitting 62 to 65 cm.
- Every order ships next-day from our warehouse in Prague to all EU countries.
- Measure your head about 1 cm above the ears, across the widest part of your forehead, with hair worn the way you'd normally wear it under a cap.
- The year ahead — 2026 — is the first in which both XL and XXL are available from the same brand.
How to know a cap is built for a big head
- The crown is deep, not shallow. A cap shaped for a bigger head wraps around it. A standard cap sits on top like a bowl perched on a melon.
- The internal band is wider. Ours is built around 61 cm, which is roughly where the inside of a standard cap stops closing.
- The strap actually closes at your size. A snapback should have spare positions left at 63 cm, not be on its last notch at 60 cm.
- The forehead leaves no red marks after you take it off. Pressure marks mean the cap is too small, no matter what the label says.
- You can slide one finger comfortably under the band. That's the fit-check the brand uses on every product page, and it works.
- The brim is proportional to the crown. On a deeper, wider cap, a longer or slightly more curved brim keeps the silhouette balanced instead of looking shrunken.
The four cap styles for big heads, compared
- Baseball cap — structured, with a stiff front panel and a slightly curved brim. The cleanest, most versatile silhouette. Browse XL baseball caps if you want something that goes with everything.
- Classic trucker hat — firm front panel, mesh rear panels, six-panel construction. Breathable in summer, ideal for warmer weather. See XL trucker hats.
- Snapback — firm crown, flat brim, plastic snap closure with plenty of positions for bigger heads. Urban look, no apology for taking up space. See XL snapbacks.
- Dad hat — soft, unstructured front panel, lightly curved brim, metal buckle at the back. The most laid-back style we make. Browse XL dad hats.
- XXL classic trucker — currently one model, the black minimalist. If you measure between 62 and 65 cm, this is the XXL trucker to look at.
What we make our caps from
I keep the material story simple on purpose. Our caps are made from organic cotton. It feels good against the forehead from the first wear, it holds its shape after washing, and it doesn't trap heat the way synthetic blends do. The classic trucker hat is the one exception: it pairs a cotton front with polyester mesh on the rear panels, because that's the whole point of the trucker style — airflow at the back of the head.
Construction matters more than fabric weight on a cap this size. Reinforced front panels keep the structured styles holding their shape. Adjustable closures — metal buckle, plastic snapback, or strap — give you fine control over fit within the 60–63 cm range. Embroidery is done in tonal or contrasting thread depending on the model. None of that is luxury theatre. It's just what a cap needs to keep its shape and close cleanly on a bigger head.
Why standard caps don't fit big heads
Most caps on the high street are built around an average adult circumference, which sits well below 60 cm. The internal band stops growing around 58 cm even on caps that call themselves "one size fits all." That's why, when you try one on at 62 cm, it perches on the crown instead of seating around the head. The brim points up at the sky and the back strap is on its very last position, threatening to pop open.
The fix isn't a bigger label. It's a different pattern. A cap built for a bigger head has a taller crown, a deeper sweatband, more room between the eyelets, and a strap with positions that actually reach. We rebuilt all of that from scratch. If you want the longer version of the brand story, it's on the about page.
What to check the day your cap arrives
- Put it on without adjusting the strap first. The cap should sit comfortably on the head, not perch on the crown.
- Slide one finger between your forehead and the inside band. It should fit comfortably. If it won't, the cap is too tight; if there's slack, tighten the closure.
- Wear it for at least half an hour, then take it off and check your forehead in a mirror. There should be no red mark.
- Adjust the strap to find the position you'll actually wear. The cap covers 60–63 cm, so the right notch is somewhere in the middle of that range for most heads.
- Check the brim sits level, not pitched up. A bigger head can push a brim skyward if the crown is too shallow — that's a sign the cap isn't shaped for you.
- If anything feels off, write to us. Returns are straightforward within 14 days of delivery, and we'd rather hear from you than have you keep a cap that doesn't fit.
When this fits — and when it doesn't
Choose this if
- Choose Head of Wonder if your head measures between 60 and 63 cm and you've been searching the high street without luck.
- Choose us if you've stretched cheaper caps until the strap broke and want one that closes cleanly the first time.
- Choose us if you want next-day dispatch from inside the EU rather than waiting two weeks for an oversized cap from overseas.
- Choose us if you measure between 62 and 65 cm and want the XXL trucker, our first cap above the standard XL range.
- Choose us if you'd rather buy four styles in one place than hunt around for a snapback here, a dad hat there.
Look elsewhere if
- Look elsewhere if your head measures below 60 cm. Our caps will sit loose on you, and a standard high-street cap will probably do the job.
- Look elsewhere if you need a cap above 65 cm. That's outside our range, even with the XXL trucker.
- Look elsewhere if you only wear fitted caps without an adjustable closure. Every Head of Wonder cap has a strap, snapback, or buckle.
- Look elsewhere if you need delivery outside the EU. We currently ship only within EU countries.
- Look elsewhere if you want fabrics like wool, leather, or technical performance blends. Our range is organic cotton, with mesh on the trucker.
Frequently asked questions
Does a 62 cm cap fit a 61 cm head?
Yes. Head of Wonder XL caps are built around an internal band of 61 cm and fit comfortably anywhere between 60 and 63 cm. If you measure 61 cm, you're at the design centre of the range, and the adjustable closure lets you tighten the cap slightly so it sits snug without pressure marks. The fit check is simple: you should be able to slide one finger comfortably between your forehead and the inside band, and there should be no red mark on your forehead after wearing.
How do I measure my head for a cap?
Use a soft fabric tape measure, or a piece of string you can lay against a ruler. Wrap it around your head about 1 cm above the ears, across the widest part of the forehead — right where the cap will sit. The tape should be snug but not tight; you should be able to slide one finger underneath. Measure twice with dry hair worn the way you'd normally wear it under a cap. The full guide with photos lives on our size guide page.
What size cap do I need for a 63 cm head?
If you measure exactly 63 cm, you're at the upper end of our XL range. Most of our caps will fit you with the strap close to its loosest position. If you're right on the edge between XL and XXL and want a little more room, the black minimalist classic trucker in XXL is the cap to consider — it covers 62 to 65 cm. Otherwise, XL is the right call. When in doubt between two sizes, choose the larger one.
Which cap style suits a bigger head best?
There's no single right answer, but the structured baseball cap is the easiest place to start because the firm front panel gives the silhouette a clean shape on a deeper crown. The snapback works well if you like a flat brim and a stronger street look. The trucker hat is the breathable option for warmer days. The dad hat is the most relaxed, with a softer crown that gives a low-key everyday feel. All four styles come in the same 60–63 cm fit.
Why don't standard caps fit big heads?
Most standard caps cap out at an internal circumference of around 58 cm. Above that, the cap stops closing properly and ends up sitting on top of the head instead of wrapping around it. The brim points up, the back strap reaches its last position, and the forehead picks up pressure marks. Head of Wonder caps are built differently from the inside out: a deeper crown, a wider internal band shaped around 61 cm, and a longer adjustable strap that closes cleanly across the 60–63 cm range.
What materials do you use?
Our caps are made from organic cotton. It's soft against the forehead, holds its shape after washing, and breathes well. The one exception is the classic trucker hat, which pairs a cotton front with polyester mesh on the rear panels for airflow — that's the defining feature of the trucker style. We don't work with leather, wool, or technical performance blends. The brand's whole range is organic cotton with the mesh accent on truckers.
How long does delivery take?
Orders ship within two business days of receiving them, usually next-day from our warehouse in Prague. Within the Czech Republic, delivery is typically one to two business days after dispatch. Across the rest of the EU, delivery typically takes three to seven business days depending on destination country. We currently ship only inside the EU — no UK, Switzerland, Norway, or US. Free shipping kicks in over €50 or the local equivalent.
Can I return a cap if it doesn't fit?
Yes. You have 14 days from delivery to return any item. Email info@headofwonder.com with your name and order number and we'll talk you through it. The cap needs to come back in new, unworn condition with no signs of use, and return shipping is at your expense. Once we receive it, we'll check it within a week and issue a refund using the same payment method you used at checkout. If the cap arrived damaged, send us a photo and we'll send a replacement free of charge — no need to return the damaged one.
Do you make caps for heads above 63 cm?
Currently one cap: the black minimalist classic trucker hat in XXL, which fits circumferences from 62 to 65 cm. Every other cap in the range is XL only, covering 60 to 63 cm. If you measure above 65 cm, we don't have a cap that will fit you yet — that's an honest answer rather than an upsell. The XXL trucker is the first step toward a broader range, and more XXL styles are on the roadmap for the year ahead.
How much do your caps cost?
Caps in our range are priced from 649 to 775 CZK depending on the style and material. The trucker hat in XXL sits at the lower end of the range, while the structured baseball caps and snapbacks are slightly higher. Pricing reflects the construction we use — reinforced panels, organic cotton, adjustable closures that actually close on bigger heads — rather than luxury theatre. You can see current pricing on the full XL caps collection.
Methodology
This guide draws on the brand's own product catalogue, the size guide I wrote and maintain, and what I learn from running the shop day to day — the conversations I have with customers by email, the fit feedback that comes back with returns, and the orders I've fulfilled from Prague over the past year. Numbers in this article are taken from the canonical fit and product data I keep on every cap we make.
