I’ve received a bunch of dudes asking me the same questions: Are all BMX seats the same size?
No.
In general, seats come in three sizes: SLIM, MID and FAT.
BUT!
Not all slim seats are the same width. And the same goes for mid and fat.
Still, they don’t differ too much, so you have nothing to worry about.
Sometimes, the same seat comes in all three sizes (like the BSD Logo seat), but that’s not always the case.
Another question I often get is: Which BMX seat size is right for me?
Let’s break the three seat sizes further, so you pick the right one easier.

3 BMX Seat Sizes For Every Rider
| Seat size | Best for | Characteristics |
| Slim | Racers, transition riders, street | Minimal padding, less bulky, great for speed & flow |
| Mid | Trick riders, park, street | Balanced padding, not too bulky, ideal for tricks & general riding |
| Fat | Jump riders, street | Maximum padding, more grip, perfect for tricks like bar spins & suicide no-handers |
1. Slim Seats
A slim BMX seat is mostly in use by racers and transition riders, who aren’t too much into tricks, but rather flow and style.
The seat will not get in the way when you’re pedaling, which is perfect if you like to go FAST!
No. Bumping.
Fun fact: Street riders are transitioning to slim seats, too, lately.
One of them is Felix Prangenberg, but he says he likes the slim version because of the (more old-school) look.
2. Mid Seats (My FAV!)
If you like to do tricks but don’t want too much padding on your seat then the mid version is perfect for you.
This seat size is primarily in use by park and street riders (even dirt). It gives just enough grip but doesn’t appear too bulky.
Note: It’s Bruno Hoffmann who prefers the mid seat size.
3. Fat Seats
This is the largest/widest BMX seat size, which isn’t really my favorite.
But it’s the ideal solution for jump riders, doing suicide no-handers, bar tricks, etc.
And it’s also widely popular in street riding for extra cushioning and grip.
Note: Broc Raiford is all about fat seats, even having his signature Odyssey Broc seat available.
Conclusion & My Recommendation
Now you know that there are three types of seat sizes available: Slim, Mid and Fat.
My recommendation:
Go with the mid version if you’re unsure which seat size to pick.
It’s an all-around size that will do the trick – guarantee!
However, it’s perfectly OK if you try all three and then decide which suits you best.
I tested them all over the years and am currently satisfied with the mid version.
