What is the diameter of the ball? Have a hollow top drum so hopefully a duel purpose.

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!

The diameter of the drum is approx. 25 inches and the length is about 21 inches.

The ball is about 2 inches in diameter. Too large for a small child to use as a therapy ball, but perfect for 8 year olds and up.

David the ball is approximately 5.5 in diameters. I hope this helps you. Have a nice day.

That's funny, it's not accurate, the ball is round and therefore has one dimensional measurement. It's like a 2&1/4" diameter ball. Fits in the hand nicely.

I just measured my cosposter and the drum is 25" in diameter and 21" wide. I didn't measure the separate base, but estimate it is about 6" high, contains the rollers, plus allows any compost liquid to drain into it. The liquid is similar to a fertilizer. I hope this helps you. John

I'm not sure the exact measurements, but it seems to be close to the actual size of a pool ball, maybe just a shade smaller.

Crystal ball seems to be a better search term:3 Inches, the size of this top plate is roughly 76 millimeters. so i'd go with something in the 70 - 90 mm range to compliment the size nicely. However, you could fine a ball of the size you'd like and measure the diameter. Have a wonderful day.

This ball is 30" in diameter when fully inflated. You may inflate it to any diameter up to that size by simply putting in less air. That way it is adjustable to your liking. Thanks for asking!

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

I am not sure of the size of the balls. I had bought it for a friend in another state. Sorry!!

The hoop opening is approximately 7.75" so any ball smaller should work. Nerf Poof balls work great for us. Our dog liked the original balls a little too well. None left to measure for you.

This purchase was a gift and I was told the size... But this might help you. http://www.ehow.com/how_5118124_measure-drum-heads.html#page=0

Haven't measured them, but they are slightly smaller than a standard tennis ball

Some kits measure the diameter including the rim around the head. do not be fooled these are 10 inch, 12 inch and 16 inches. They are measuring the shell and rim at the widest part, not the size of the top surface of the drum head. but the layout is not common and will be hard to find 3 packs sold like that, i saw them in a few brands, but this is not a match for you. look for 10, 12 and 16.

The ball itself is about 2 inches. The surrounding metal is closer to 2.25 inches.
