The Best Pull Up Bar Diameter

Best Pull Up Bar Diameter

My guess is you’re on this page for one of two different reasons:

First, you’re building your own DIY Pullup Bar Setup and you’re trying to figure out what the best pull up bar diameter is so you can buy the correct size pipe for your build.


You’re buying a pull-up bar and you want to make sure the diameter is correct for what you want.

Either way, you’re in the right place.

The most common pull up bar diameter is a 1.25″ outer diameter. The pull-up bars used for the Army Combat Fitness Test (the original standard) are 1.5″, but can have a variance between 1.25″ and 1.75″.

The 1.25″ outer diameter is the size you’re going to come across most often when shopping for a pull-up bar and is also the size I would recommend if you’re trying to build your own.

To give you a few more points of reference I’m going to share with you a few common pull-up bars you can buy.

Finally, if you’re building your own, make sure you understand the difference between inner and out diameter.

Common Pull-Up Bar Diameters

Here are a few of the most popular pull-up bars for garages and home gyms. I also included a couple popular racks that come with pull-up bars. What you’ll notice really quick is that 1.25″ is pretty much the standard across the board.

Diameter vs Outer Diameter

If you’re building your own pull-up bar, there is one thing to keep in mind when shopping for pipe.

There is a difference between the inner and outer diameter of a pipe. The listed diameter when you’re buying a pipe will generally be the inner diameter.

Take this pipe from Home DepotOpens in a new tab. for example. The pipe is listed as a 1″ x 48″ Black Steel Pipe. The inner diameter is 1.05″, but the outer diameter is 1.315″.

Make sure to look through the full specs to get a pipe that is the proper outer diameter for what you want.

Also, for what it’s worth, I’ve talked to a few friends who have tried to go with a 3/4″ x 48″ pipe and while it didn’t break, it did flex a little more than what they felt comfortable with.

Wide Grip Pull-Up Bars

Looking for a fat grip pull-up bar? What is the diameter on fat grip bars?

First, not to get too off-topic, but why would you want a fat grip pull-up bar? As you can probably imagine, a fat grip bar is extra challenging for your grip. So if you want to develop a really strong grip, like say you’re training for American Ninja Warrior (only sort of joking there), then a fat grip bar would be perfect.

Fat Grip Bars are typically 2″. These are a little harder to find, but a fat grip option is actually available for the Rogue Rack in the table above.

Like the idea of training with a fat bar, but you don’t want to have to buy an entirely different bar? Try out these Fat GripzOpens in a new tab.. They immediately turn any bar, barbell or dumbbell into a fat grip bar. I’ve been using these types of bar attachments for years and highly recommend them.

Final Thoughts

1.25″ is the standard size for pull-up bars. Anything thinner than that may end up causing you some stability and/or durability issues. A slightly bigger bar won’t make that noticeable of a difference until you get up around a 2″ diameter which is standard for a fat grip bar aka thick bar.
