Biggest Bodybuilding Arms

Updated January 21, 2021

Welcome to the gun show! So, the question is: which bodybuilder has the biggest arms? Before we look at the answer to that question, let’s get something straight:

Biggest Bodybuilding Arms

Most bodybuilders lie about arm size!

What did you expect? Did you really think that 20 inch pipes were are prevalent as tattoos at a biker bar? It’s hard to achieve 20 inch arms.

And for natural bodybuilders…it’s impossible. Impossible? Yes, impossible. Unless, of course, Mr. Natural is carrying around 58% body fat.

Arnold Schwarzenegger claimed to have 22-23 inch arms pumped. Arthur Jones measured Arnold’s arms when they were pumped, and they taped out at 19 3/4 inches. Quite a tall tale told by the Austrian Oak.

manfredhoeberlArthur Jones is on record as saying that he taped the arms of Ray Mentzer and Sergio Oliva around 20.5 inches – much larger then Arnold’s. Looking at Oliva’s arms, I tend to believe Arthur Jones.

Some say that Manfred Hoeberl had the biggest arms. Manfred was a strongman competitor, and not a bodybuilder. It is claimed that his arms measured out at 24-25 inches.

Mr. Olympia champion Ronnie Coleman has 22 inch arms on competition day. If you look at photos, and consider the fact that Ronnie was taking far more drugs then Arnold, it isn’t hard to believe that Ronnie’s arms where much bigger.

And what about natural bodybuilders? Reg Park had 18.5 inch arms, Steve Reeves supposedly had 18 inch arms, and John Grimek’s arms were 18.3 inches. Unless you’re incredibly tall, or a genetic freak, you will never hit 18 inch arms as a natural. (of course, these men were relatively lean too).

The biggest arms in bodybuilding ever, is probably between Victor Richards, Ronnie Coleman, Paul Dillet and Markus Ruhl. Take your pick!

However, the BEST arms in the history of bodybuilding probably belong to Arnold or Lee Priest, who both have epic proportions and the most aesthetically pleasing arms.

Who has the Biggest Arms in Bodybuilding Right Now?

IFBB pro’s don’t typically reveal how many inches their arms are, at least to the general public.

…A gentlemen never tells.

However, if we were to judge IFBB pros at the time of writing this article, you’d have to say Big Ramy, then possibly Roelly Winklaar are the biggest of the bunch.

However, the biggest arms aren’t always the best arms – hence how neither of these two have ever won a Mr Olympia. Roelly’s arms (to be fair to him) are very aesthetic-looking and he possibly has some of the best triceps bodybuilding has ever seen.

So what arm size is respectable for the Average Joe natural bodybuilder? 15-16 inch pipes. If your guns are that big, people will consider you strong, and most likely will recognize you as a bodybuilder.

And if a natural claims to have 20 inch arms, ask for photos. He just may be the greatest of all time. No photos equals a load of bull. Anyone with arms that big would love to show them off.

It’s also worth noting that 15 inch arms can look bigger than 17 inch arms, if they are lean and ripped – rather than being covered in fat and looking smooth. This is because they have that ‘wow factor’, with cuts and striations, aka a lot more impressive, compared to someone with higher body fat.
