Baseball Field Dimensions by Age
Most young players start on a 46/60 field (46 feet from the rubber to the plate, 60-foot bases), many move to 50/70 between ages 11 and 13, and everyone plays the full field by high school: 60 feet 6 inches, 90-foot bases, and a 10-inch mound. Pick a league and division below for the exact numbers and what changes at the next level. Covers Little League, Cal Ripken, Babe Ruth, PONY, USSSA, Perfect Game, high school, college, and the pros.
Baseball field dimensions chart by league and age
Pitching distance is measured from the front edge of the pitching rubber to the back point of home plate. Mound height is how far the top of the pitching rubber sits above home plate. Little League, Babe Ruth, high school, college, and pro figures come from their rulebooks. Travel and other league figures come from league and event rules, which can change by season or event, so confirm with your league. Last checked October 2026.

Baseball field size by age group
Age alone doesn't set the field. The league does. At 8U and younger, player-pitch games in PONY, USSSA, and Perfect Game use 40 feet with 60-foot bases, while Little League Minors pitch from 46 feet. At 9U and 10U, every league on this page pitches from 46 feet, with 60-foot bases in Little League, Cal Ripken, and PONY and 65-foot bases in USSSA and Perfect Game. At 11U and 12U it's usually 46/60 or 50/70, depending on the league, though a 12 year old in Little League Junior League plays the full field. At 13U and 14U, expect anything from 50/70 to the full field, set by the league or the event. From 15U on, the leagues here play the full field: 60 feet 6 inches, 90-foot bases, and a 10-inch mound.

| 8U | 40/60 (46/60 in Little League Minors) | PONY Pinto, USSSA 7U-8U, Perfect Game 8U |

What 46/60, 50/70, 54/80 and 60/90 mean
Coaches and tournament flyers describe a field with two numbers. The first is the pitching distance in feet, and the second is the length of the base paths. A 46/60 field is the standard for Little League Minors and Majors, Cal Ripken Minor and Major/60, and PONY Mustang. 50/70 is the bridge field, used by Little League Intermediate, Cal Ripken Major/70, PONY Bronco, and most 11U and 12U travel ball. 54/80 shows up in PONY 14U, some 13U and 14U travel events, and some local Junior League regular seasons. 60/90 is shorthand for the full field, where the rubber actually sits 60 feet 6 inches from the plate. One more to know: USSSA and Perfect Game play 9U and 10U at 46 feet with 65-foot bases.
Little League field dimensions by division
Little League sets the field by division. Minor League (ages 7 to 11) and the Major Division (ages 9 to 12) share a 46/60 field with a 6-inch mound. The Intermediate (50/70) Division, for ages 11 to 13, moves the rubber to 50 feet, the bases to 70 feet, and the mound up to 8 inches. Junior League (ages 12 to 14) and Senior League (ages 13 to 16) play on the full field: 60 feet 6 inches, 90-foot bases, and a 10-inch mound. Local leagues may play the Junior League regular season on a smaller 54/80 field, so ask your league which one he'll be on. These figures come from the Little League rulebook.
| Division | Ages | Pitching distance | Base paths | Mound height |
|---|---|---|---|---|
| Minor League | 7-11 | 46 ft | 60 ft | 6 in |
| Major Division | 9-12 | 46 ft | 60 ft | 6 in |
| Intermediate (50/70) | 11-13 | 50 ft | 70 ft | 8 in |
| Junior League | 12-14 | 60 ft 6 in | 90 ft | 10 in |
| Senior League | 13-16 | 60 ft 6 in | 90 ft | 10 in |
What changes for a pitcher when the field gets bigger
Every step up adds distance, and usually a taller mound. In Little League the rubber moves from 46 feet to 50 to 60 feet 6 inches, and the mound rises from 6 inches to 8 to 10. With the plate farther away, the same fastball gives the hitter more time to react. A 60 mph pitch from 46 feet gives a hitter about as much time as a 79 mph pitch from 60 feet 6 inches, and our pitch speed converter does that math for any speed. The common mistake is trying to throw harder to cover the extra feet, and that usually costs strikes. Expect an adjustment, judge his command against his own last season rather than his teammates, and keep the effort smooth. Smooth is fast.
Pitching mound height by level
On a regulation 60 feet 6 inch field, the top of the rubber is 10 inches above home plate, and the front of the mound slopes down 1 inch per foot, starting 6 inches in front of the rubber and running 6 feet toward the plate. Youth mounds are lower. Little League uses 6 inches for Majors and below and 8 inches on the Intermediate 50/70 field. PONY climbs from 4 inches at Pinto and Mustang to 6 at Bronco, 8 at Pony 14U, and 10 at Colt and Palomino. Cal Ripken's Major/70 mound runs 6 to 8 inches depending on the league. USSSA and Perfect Game rules don't set a mound height through 14U, so it depends on the field you're playing on.
How to measure pitching distance
Measure from the front edge of the pitching rubber to the back point of home plate, the corner of the plate that points at the catcher. Every distance on this page is measured that way. If you set up a practice spot at home or at an open field, use those same two points and his division's distance from the lookup above, so his practice throws match what he sees on game day. A tape measure takes two minutes and beats pacing it off. Mark the spot with tape or a painted line so every bullpen starts from the same place.
Common questions
What are Little League field dimensions?
Minor League and the Major Division play at 46 feet from the rubber to the plate with 60-foot bases and a 6-inch mound. The Intermediate (50/70) Division plays at 50 feet with 70-foot bases and an 8-inch mound. Junior and Senior League play on the full field: 60 feet 6 inches, 90-foot bases, and a 10-inch mound.
How far apart are the bases in Little League?
60 feet in Minor League and the Major Division, 70 feet in the Intermediate (50/70) Division, and 90 feet in Junior and Senior League. The pitching distance steps up with the bases: 46 feet, then 50 feet, then 60 feet 6 inches.
What size field does 10U play on?
Every league on this page uses a 46-foot pitching distance at 9U and 10U. The bases are 60 feet in Little League, Cal Ripken, and PONY Mustang, and 65 feet in USSSA and Perfect Game travel events. Mounds are 6 inches in Little League and Cal Ripken and 4 inches in PONY Mustang. USSSA and Perfect Game rules don't set a mound height, so it depends on the field.
What size field do 11U and 12U play on?
It depends on the league. Little League Majors (ages 9 to 12) plays 46/60, and Cal Ripken Major/60 does too. Little League's Intermediate (50/70) Division (ages 11 to 13), Cal Ripken Major/70, PONY Bronco 12U, and USSSA and Perfect Game 11U-12U all play 50/70. A league age 12 player in Little League Junior League plays the full field: 60 feet 6 inches with 90-foot bases.
What size field does 13U play on?
13U is the most mixed age. Little League's Intermediate (50/70) Division takes players through age 13, while Little League's Junior League and Babe Ruth 13-15 play the full field: 60 feet 6 inches with 90-foot bases. USSSA and Perfect Game 13U events use either 54/80 or the full field, set by the event, and PONY's 14U division plays 54/80. Check the league or event rules before the season so he practices at the right distance.
How high is a pitching mound?
10 inches on a full-size field (high school, college, and pro). Little League uses 6 inches for Majors and below, 8 inches for Intermediate 50/70, and 10 inches for Junior and Senior League.
When do kids move to 60 feet 6 inches?
Little League moves to the full distance in Junior League (ages 12 to 14) and Senior League. Babe Ruth plays the full field from 13. In travel ball, 13U and 14U events use either 54/80 or the full field depending on the event. PONY 14U plays 54/80 and moves to the full field at Colt 16U. High school is always 60 feet 6 inches. Some local leagues play the Little League Junior regular season on a smaller 54/80 field.
What are high school baseball field dimensions?
High school baseball, under NFHS rules, plays at 60 feet 6 inches from the front of the rubber to the back point of home plate, with 90-foot bases and a 10-inch mound. That's the same field used in college and the pros, so freshman, JV, and varsity all play on the full-size diamond.
What does 50/70 mean in baseball?
A 50-foot pitching distance with 70-foot bases. It's the bridge between the 46/60 youth field and the full field, used by Little League's Intermediate Division (ages 11 to 13), Cal Ripken Major/70, PONY Bronco 12U, and most 11U and 12U travel ball.
