Purchased the 18" for my grandson and the size is perfect. I was glad I had read the previous reviews that indicated a pump would be needed - and was it ever!. This ball will not hold air. We have to pump it up everytime he wants to use it (which is about every day). He previously had the Ball, Bounce and Sport Ball, Bounce and Sport Cars Hopper and once it was inflated it stayed pumped up - NOT THIS BALL! I gave it five stars for fun and deducted 3 because it will not stay inflated - disappointed!
