Dimensions of Little League Baseball Field: Bases, Mound and Fences
Little League field dimensions: 60-foot base paths, a 46-foot pitching distance, a recommended 200-foot fence, and how other divisions change these numbers.
A standard Little League baseball field, used for the Major Division and the Minor League, has 60-foot base paths and a pitching distance of 46 feet. Little League recommends an outfield fence at least 200 feet from home plate. Older divisions play on larger diamonds, and Tee Ball may use a smaller one, so the exact numbers depend on the level being played.
The Standard 60-Foot Diamond
Little League’s field specifications set the distance between bases at 60 feet for baseball divisions of players 12 years old and under. Little League’s official field layout diagram for the Major and Minor divisions shows these key measurements:
- Base paths: 60 feet between bases.
- Home plate to second base: 84 feet, 10 inches.
- Second base placement: centered on the point where the base lines cross.
- Base cutouts: a 9-foot radius of infield dirt around first, second and third base.
- Home plate area: a 20-foot circle around home plate.
The same diagram notes that Tee Ball base paths may be 50 feet instead of 60.
Bases That Come Loose
Little League’s field conversion guide says first, second and third base, at every level, must be able to pop free of their anchors. The guide’s cutaway shows a dis-engageable base along with a metal post, a metal sleeve, a concrete anchor and a low-profile rubber pad; the pad sits at ground level and can stay in place while the base is removed.
The Pitching Distance and Mound
46 Feet to Home Plate
Pitchers in the Major Division and the younger divisions throw from 46 feet. Little League’s conversion guide says this distance is taken from the rear tip of home plate to the front of the rubber.
Mound Measurements
Little League’s pitching mound layout for the Major and Minor divisions gives these figures:
- Mound size: a circle 10 feet in diameter.
- Pitcher’s plate: 18 inches wide by 4 inches deep.
- Level area around the plate: 40 inches by 17 inches.
- Height: the conversion guide shows the standard pitcher’s plate sitting 6 inches above the level of home plate.
Behind the level area, the layout diagram marks a rear slope that runs gradually down to the edge of the circle.
Outfield, Fences and Foul Poles
The field specifications recommend an outfield fence at least 200 feet from home plate for baseball’s Major Division and below. The official layout diagram adds several recommended features:
- Fence height: a 4-foot fence placed 200 feet or more from home plate.
- Warning track: 10 feet wide in front of the outfield fence (recommended).
- Foul poles: at least 10 feet high.
- Foul lines: the distance from home plate to the nearest fence along each line is 200 feet or more.
If one field has to serve both the standard 46/60 division and Intermediate (50/70) games, Little League’s conversion guide says the fence should sit somewhere between 200 and 275 feet from home.
How Other Divisions Change the Field
Little League does not use one field size for every age group. Little League’s field specifications, division pages, layout diagrams and conversion guide give these baseball dimensions:
- Tee Ball: the layout diagram notes base paths may be 50 feet.
- Minor League and Major Division: a 60-foot diamond with a 46-foot pitching distance.
- Intermediate (50/70): bases 70 feet apart, the rubber 50 feet from home, and 99 feet from the rear tip of home plate to the middle of second base. The mound grows to a 12-foot diameter and the pitcher’s plate sits 8 inches above home plate level.
- Junior League: 90-foot bases, with the rubber 60 feet 6 inches away. For the regular season, the field specifications allow 54 feet as a local option.
- Senior League: 90-foot bases, with the rubber 60 feet 6 inches away.
For the Junior and Senior League divisions, the recommended outfield fence distance rises to 300 feet.
Sharing One Field
Little League’s resizing article advises a league that wants to host Intermediate games to convert a Major Division (46/60) field rather than a 60/90 one. Its reason: on a 46/60 field the bases can be pulled out so they are not in play. A 60/90 field is the weaker choice, the article says, since its anchors would sit out in the outfield grass and half of its mound would lie inside the playing area. The conversion guide then widens the infield dirt with an arc kept 69 feet from the rear edge of the old rubber, adds base anchors for 70-foot paths, and enlarges the mound with a second rubber at 50 feet. During Intermediate games, the 46-foot rubber has to come out.
