I keep reading that the ball seems small. I'm 5'5" and according to box need a 55cm, would the 65cm be too big?

I'm 5'2" and this ball works great for me. It's just the right height to balance on like a chair and they don't say this on here, but it's also weighted so if you fall off of it - it doesn't go far. Hope this helps!

I am 5'4 and the ball is perfect. Any smaller, and it's suitable for toddlers/small kids, no joke.

It will depend a little on what you're using the ball for. I am also 5'5", but I'm currently 280 lbs. I sit on the blue 75cm ball every day at work as my office "chair". Mine is somewhat too large for me fully inflated as it will push my calves away from me, not really allowing a "proper" 90 degree bend at my knees. Without this size ball, however, I'd be sitting far too low at my desk to function. As an exercise ball, I firmly believe the 65 cm ball will work well for you with no question. As an office "chair" make sure to account for your weight and measure to ensure this will give you enough height. Measure the distance from hip to floor while sitting on your current desk chair (adjusted to your required working height). Then see if you can sit on a friend's exercise ball or a ball at your local gym and measure again from hip to floor and compare. If the properly inflated ball allows you enough height to work, you're good to go!

Jay, I personally would not want smaller sizes for lighter weights. I can say the grip on this is good and that's about all I was looking for in the ball.

Something close to 5 inches should work. My son was 8 when I gave him a 7 in., he could have gone a bit bigger, but it was fine. It also depends in the size if child. If close to average I wouldn't go bigger than a 5 inch ball. Hopefully this helps.

Typically, individuals less than 4 feet, 6 inches require a 30 cm ball. You should choose a 45 cm ball if you are between 4 feet, 6 inches to 5 feet tall. From 5 feet to 5 feet, 5 inches, select a 55 cm ball. If you are between 5 feet, 6 inches and 6 feet, 2 inches, use a 65 cm ball. If your height exceeds 6 feet, 2 inches tall, opt for a 75 cm ball.

I'm 5'4 and I think the 75" is the perfect height to sit me at the right level for my desk at work... also why I purchased this ball. Any smaller and I'd be sitting too low to reach everything appropriately.

I am 5 foot 3 and thus ball us too small for me. I wanted to be able to do crunches on it as well as sit or lay on it to do dumb bell eexercises.if you are my height or taller, I would go bigger.

A red Isokinetics anti burst ball, 55, fits very snugly, makes it a little taller. Other colors of the same 55 size need to be pumped up bigger to make them firm enough.

I got mine on ebay and also got a smaller ball. I'm hoping the answers are correct and it will stretch out. I know the ball I already had seems a lot thinner than this one. So maybe that's why.

yes this is big enough. However you shoukd google to find the right ball sixe for your height. I am 5.4 feet and this size is perfect for my office desk.

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.

Not really. I you're purpose is to use the ball at a desk, it will likely be too low and you will have to purchase a special structure that is specifically available for use with stability balls. Otherwise a 75cm is a big ball. How tall are you? Are you sure you've filled it completely?

I am 5'2", use the ball for leg excercises. My daughter is 5'9" and my husband is 6' and they both use the higher ball for back and body.

There seem to be three options to purchase - a 55cm, 65cm, and 75cm. They're different colors depending on the size selected.

I'm 5'3" and a lot lighter than 245. I think it may feel a bit small for you given it feels pretty comfortable for me. Sometimes sporting goods stores have similar machines set up, so you may want to 'size' a similar machine in the store first. This is what I did but for a different reason...I needed to size it for the room/space where it is kept. Sometimes a visual helps.

I bought my ball when I was pregnant too. I'm 5'6 and bought the large one. I loved it then and still use it now. Baby even likes being bounced on.

This ball will be the right size for you though you may find that it is too low for a standard desk. I highly suggest utilizing this ball as a chair though you may wish to lower your desk or find a "chair base" that fits this ball size.
