The ball size is fairly unimportant - it is the perfect size to fit beneath your three middle fingers while your hand is relaxed. Used with the right hand, your thumb relaxes over the left-click button, and the pinky is relaxed but poised over the right-click button. You will be controlling the cursor's moves with the mid-parts of the three middle fingers in a relaxed, unstressed manner, rather than with the fingertips, which is stressful to the hand, as I find the Logitec model with the red ball.

about 1-1/2" wide. not sure about circumference. I have arthritis in my hands and it is very very comfortable. I make sure the trackball is on the same level with the keyboard.

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.

About 2-1/4 inch high... It's perfect for my hand... Not too high and not too low.p.s. I checked it again, after reading the other comments, and it is 2-1/4 inches high from the base to the top of the ball.

Is a little smaller. But not too much.Even the dogs of middle size can grab the ball without problems.

I do not know the diameter, but it's smaller than a basketball ... about the size of a volleyball. It is shipped inflated. Hope this helps.

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

It's 18" PLEASE trust our age recommendations. At Waliki we are pros. We have tested this size and it is the right one for that age group. You can make the ball smaller or larger by inflating it more or less. It's super durable. Your little princess will love it!

From the view shown online the ball is about 4 inches across. Not very large at all. My yorkie and small poodle play with it.

Smaller than a standard soccer ball....the size of a grapefruit. Needs to be pumped up when you get it though. Pump not included.

The description is not helpful. Is the inflated ball 75 cm diameter or 75 cm high?

Hi, all I can tell you is that the large is huge. Much larger than expected. About the size of a blimp! I would call isokenetics before purchasing. Btw, the quality of the ball is top notch. Good luck.

I would estimate a little bit larger than a basketball. We bought it for a gift and don't have it to look at. Hope this helps.

It is a little bigger, but possibly it could fit.... The ball is heavier than a tennis ball

They are about 2 inches. Very large compared to the small sparkle balls I usually get my kids.
