I know this is a site for Baseball, but there is not oone for fastpitch softball. Anyone know the deminsions of pitchers mound in fast pitch for youth. U-10?

35 feet!

Is softball even a sport? As for your question it's might be the same as slow pitch.

Everything is a fast pitch when the mound is 35-40 feet away...............softball is so boring no one ever hits

14u is 40 ft and 12u is 35ft
im pretty sure 10u is 35ft also if not then 30ft
