Does the given size for a given ball represent its actual circumference, or is it some other size?

These sizes are for the diameter of the balls (across) and not circumference (around). The page you use to select sizes also shows the equivalent in inches. I am 6'2" and the large (75cm) ball is about the height of a chair. My wife uses the medium size as she is 5'9". Good quality balls. I still use mine often after ~3 yrs.

You have to fill the ball with air. I use a small air compressor attached to my cars dc plug. The more you fill the ball the larger it gets. We use them for acrobatics at our dance studio, it actually can get bigger then the specifications.

about the size of a tennis ball or a tad smaller, of course some are bigger and some are smaller, but overall, I would say, tennis ball size.

My apologies... My measurements of 3.5 and 2.75 are for the circumference, not the diameter!

It just means the same as numbers 1 through 4, instead these are 6 through 9. Easy to identify as your ball.

Hi, I don't recall how it was measured. Only know that it arrived being much larger than expected. i would call the company's customer service. also, fyi, this is a very sturdy ball; however, the blue peanut has never inflated evenly.

Those are the correct dimensions, the glove is great for an 11" ball but actually seems a bit small for 12" balls so I ordered a 14" glove.

I'm not sure. The product information definitely has the measurements if you read further down you'll come across it.

There are 3 sizes (3,4,5) for a soccer ball, Size 5 is for adults (14-16 oz with circumference of 27-28 inches). Size 3 is for young children (11-12 oz with circumference of 23-24 inches). This ball is size 3 but only weighs 9 oz.

Size 5. Go to this link and read the section on the bottom entitled "Choosing the Right Size Ball.": http://www.dickssportinggoods.com/info/index.jsp?categoryId=13299258&infoPath;=222998#5

I dont know where you got this information, but who ever provided it is crazy. The round ball is about 2 1/4 inches diameter. It is always fully inflated and bounces very high.

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.

I'm not sure what the "measurement for the ball diameter" is but if you've ever used a fitness ball at the gym, is the biggest one they've got which I think is the standard size.

Nope. Just means the ball has a diameter of 3 inches. If you squeeze it, it depresses perhaps another inch in.The rubber is a very thin material, not designed for longevity. The originals in the 1950's were very thick rubber.

Yes, just measure the circumference in mm, and enter the value in the set up.

The diameter should be half of the circumference but most dome shapes are not perfectly round and require volume, height, surface tension, air pressure, etc. to be considered. To calculate circumference of the base, you use: C=2 pi r. The diameter should be half of that value.Hope this helps!!! ROFLMBO

If I remember correctly, the ball was about 10" in diameter...maybe a bit more. It's a good size, like a soccer ball.

Circumference is 7 3/4 inches--it is a normal sized rolling pin. It has more weight than traditional wood ones which make it great for rolling out stiff doughs.
