Fits the normal size (medium) balls. Very compact and throws well. Need to put a little extra muscle into it if you want to throw it far, but overall a great buy and has lasted a long time. For the lazy thrower this would not be ideal because you need to bend down to pick up the ball since the reach isn't as long as the normal size..so there is a little more work involved. If this is an issue for you, get the next size up.
