I apologize I'm not sure I can help you. I personally went to a local shop and tried on giro helmets so I could see how they were sized. Then I got on amazon and ordered it for much cheaper. There are a couple of people who did reviews on youtube they go over sizing. Sorry I hope this helped a little

I wear a 7 3/8 fitted ball cap and I purchased the Large Boonie hat. It fits loosely but perfectly. I would consider the next size up for a 7 3/4.

I don't have measurements, but I, too, have a rather large noggin, and it fits fine. it has two straps which help adjust the size. when neither of them are attached, it's quite loose on me. unless you suffer from some form of gigantisim or elephantitis, you should be fine.

Measure your head. If you find you are between two sizes, then I recommend her the bigger one.Brainsaver Rubber Helmet Sizing Chart:To ensure a perfect fit, measure the circumference of your head starting in the middle of your forehead and match it with the sizes below.XS 20.10 in - 20.50 in (51-52cm),S 20.60 in - 21.30 in (52-54cm),M 21.40 in - 22.00 in (54-56cm),L 22.10 in - 22.90 in (56-58cm),XL 23.00 in - 24.00 in (58-60cm)

I have mine at nearly the maximum setting at most times.. my head is medium-large I would say. So no, your head size should be fine. If you had a big head I would stay away from these though.

Well, it fits me good and can stretch more. I am 180cm high and 85 kilos weight. Head is prproportional. Just measured my head by forhead it is 59cm around

The actual measurement of my head size is 21 1/4 inches. This hat fits just right.

Measure your head-with a tape measure. Mine hasn't changed since high school football. Hat fits great and has not changed size with use.

Measure your head with a tailors tape and then use a sizing chart. Thats the best way to find a sure and safe fit.

Sorry so late to reply, but I just now saw this. I have a pretty big head (hat size 7 3/4) and these fit fine. They go around the back of your neck, not over the crown of your head. It's possible your head might be too wide, ears too far apart (everyone's head is shaped differently), but they work fine and are very comfortable on my big head.

Get a flat tape measure (like your granny used in sewing) and measure your head right above the ears. A lot of hats sold have a size chart. And if you have thick curly hair take accountability for that in your measuring. Most one size fits all is for small heads....hint.

I think there's a sizing guide probably for the helmet on amazon. They should be standard sized, so yeah just measure your head. Or go to local shop that sells helmets and try on a large

I have a medium size head and it fits fine, and there is plenty of room left to adjust/increase the size, so you should be fine.

I have a pretty big head too. Not sure what my hat size is, but it fits me with plenty of room to spare. It's a really nice helment for the price.

A size medium fits a 58 cm (22.75 inches) circumference head comfortably with or without a light hat or headband underneath. Great helmet!

I followed this from the listing. "The solution is a forgiving, four-way stretch fabric in three tube sizes - M (7 - 7 1/8 hat), L (7 1/4 - 7 3/8 hat) or XL (7 1/2 - 7 3/4 hat). If you do not know your hat size, you can measure your head with a string or flexible tape measure, just above the ears where you would normally wear a hat. M = 21 1/2" - 22 1/4" L = 22 3/8" - 23" XL = 23 1/8" - 24"

The 53cm should be perfect for you then. I'm 5'11 and it was a tiny bit small for me.
