The fences are the shortest and longest USA Softball allows for its championships; local fields vary. Little League’s 200 feet is for every softball division.

8U isn’t in USA Softball’s national table: the local association sets it. Little League Tee Ball softball can also play on a 50-foot diamond.

Only the mound moves

Unlike baseball, where a young player goes from 60-foot bases to 90, a softball player plays on 60-foot bases from her first kid-pitch game through high school. The pitching distance is what changes, stepping back to 43 feet at about 14. The pitching distance page has more on that jump.

The circle

The pitcher’s circle has an 8-foot radius around the pitcher’s plate (16 feet across), at every level. It’s the line that starts the look-back rule.

Boys’ and men’s fastpitch

Boys’ fastpitch from 14U and men’s fastpitch pitch from 46 feet. Bases stay at 60 feet, and men’s fields are deeper: 225 to 275 feet.

Slowpitch is different

Slowpitch uses longer bases and pitching distances: 70-foot bases and 50 feet for adults. See slowpitch vs fastpitch.
