Okay, so, I wanted to figure out what size tennis balls are. I mean, they all look kinda the same when you’re watching a match, right? But I got to thinking, there’s gotta be some kind of standard, you know?
So I did a little digging. Turns out, the big shots in tennis, the International Tennis Federation, or ITF, they’ve got rules about this stuff. I went straight to their website.

Here’s what I found out:
- Diameter: Tennis balls are supposed to be between 2.57 inches and 2.70 inches across. That’s like, a little bigger than a golf ball, if you’re trying to picture it.
- Weight: They should weigh between 1.975 ounces and 2.095 ounces. Not too heavy, not too light, I guess.
There are also some rules about how much they bounce and how they handle getting squished, but that’s getting a little too technical for me.
Then, I started thinking about how the type of ball can actually change your game. I read somewhere that using the right ball for the court surface and your skill level can really make a difference. Makes sense, I suppose. Like, you wouldn’t want a super bouncy ball on a slow court, or a really heavy ball if you’re just starting out.
I also found that there are different types of tennis balls such as regular-duty balls, extra-duty balls, and high-altitude balls.
So, yeah, that’s my little adventure into the world of tennis ball sizes. Who knew there was so much to it? I just wanted to know how big they were, and I ended up learning a whole bunch of other stuff. That’s how it goes sometimes, right? You start with a simple question, and before you know it, you’re down a rabbit hole of information. Anyway, hope you found this interesting!
