What's the diameter of the ball? How hard is it?

The porcupine massage ball is maybe 3-4 inches in diameter. It is not hard at all, but mushy. It is spikey and compresses easily when rolling your foot on it.

The diameter is only about 4 inches. The ball I received when I ordered this was very soft and flattened easily.

Bigger than a golf ball and smaller than a tennis ball. Maybe handball sized. Really too soft to be of any value-- i find a simple golf ball does a bettehor job. For me, the only real value was in the wooden roller.

I'd say about 2-3 inches. Its small but good enough. My feet size are a 4 in men, 6 in women, which are sort of small but chubby feet. Im a runner and I love using it. Although the item isnt big, I like moving it around to massage my whole foot. It is a good product especially for those who run or stand all day.

I apologize, I described the diameter for the wooden stick. The ball is at least the size of a hand ball. It is about maybe 3-4 inches.

I do not believe the size is on the ball but I would say it's a small ball. The smallest of the three choices when buying an exercise ball.

it's about an inch around bigger than a typical volleyball. it's a perfect ball for indoor sports such as indoor soccer. my boys love it. it's also great for begginer volley ball players.

The balls are 1.5 inch (38mm) diameter. Almost exactly the size of a ping pong ball.

Sorry. I am in NYC and the ball is in California. But, it is a very small ball. I would say the diameter is no more than 8 inches. My 20 month old grandson loves it.

The diameter of the ball is about the same as a tennis ball...maybe a tad bit smaller. The balls are not hollow, they are solid rubber. Just want to say that these work so well for me, my husband, and our children that I bought two more for other family members! They have been so helpful!

It is 10 3/4 inches circumference and about 3.43 inches in diameter. It is very heavy for a ball, it does not giggle unless I shake it and even when it rolls, it does not seem to giggle. It is thick rubber and my 6mo old Black Lab plays with it may be too heavy for a smaller dog. Hope this helps.

They are approximately 4 inches diameter -- bigger than a tennis ball but smaller than a soft ball.

It is just a tiny bit smaller than a tennis ball.It's made from rubber but is very hard and durable. My dog chews on it constantly and it still looks new a month later.

I gave it as a gift. It is supposed to be about 7 inches in diameter and that seems about right from my memory of it. My nephew took it out of the box and played with it that night. He seemed happy with it.

The diameter of the ball is about 3 1/2 inches. The color fades in and out through about 4 colors. It is fairly bright and lights up our entire 15 x 15 bedroom. Hope this helps.

I gave this ball to my grandson. I think we inflated it to about 10 inches in diameter. It doesn't matter--he loves this ball! We all do. It's soft and easy to grab. I'm planning to get more of these fun balls for him and my newest grandson for Christmas.

I do not know the exact diameter, but I drilled a bigger hole to fit, what I think is, a regular ball.

Not sure the exact diameter but the normal size golf ball just slides in. If you point the barrel down it will roll out. you can wrap a piece of tissue paper to make it fit tighter.

Did nobody on this thread get out an actual ruler? This ball is 2.5 inches in diameter, which is 37.2% LARGER than the 2.25 inch size that everyone's saying. (Do the math. Volume = 4/3*pi*r^3.) I bought this to replace my 2.25 inch massage ball, but at 2.5 inches, it's too big.
