Baseball is a bat and ball game which is played between two teams. There are nine players in each team. Moreover, it has nine innings with alternate batting and fielding.
To make this game fair and safe, you must know about baseball field dimensions. In this guide, we have written all MLB baseball field length & sizes for baseball ground including youth leagues and professional games.
Baseball Field Size
Major league baseball (MLB) decides the standard dimensions of the baseball ground. You have to follow MLB official guidelines to keep the game fair and safe.

Baseball Field Size in Meters
A standard baseball field has a 27.43 meters gap between each base. You can place the pitcher 18.44 meters from home plate. The outfield fence around 91 to 122 meters away from home plate.

Baseball Field Dimensions in Feet
In a standard adult baseball field, you have to design each base 90 feet apart. You will see the pitcher’s mound is 60 feet 6 inches from home plate. The outfield fence is 300 to 400+ feet from home plate.

Baseball Infield Dimensions
The infield is the square zone at the center of the baseball ground. It has four bases such as home plate, first, second and third. These all arranged in a diamond shape. You use this section to play most of the action, hitting, running and fielding. Below you can see baseball ground marking and infield sizes.
Diamond Zone
The baseball diamond shape area is a square with 90 feet (27 meters) on each side. You can measure this distance between two bases. This is the main section of the baseball field. When you hit the ball, you have to run around the bases of this area and can stop at any base.
Coaches’ Box
There are two coach boxes in a baseball game. You will first box near first base and second box near third base. These rectangles have dimensions of 20 ft by 10 feet. Generally, batting team coaches stand inside the boxes. They assist base runners and provide them equipment such as protective gear & sliding gloves.
On Deck Circle
The on deck circle is located in foul territory which is part of the infield area. This circle is 5 feet in diameter. Basically, the on deck batter (next batter) uses this zone to warm up and get ready safely before their turn at bat.
Pitcher’s Mound:
The pitcher’s mound is a raised & circular area in the middle of the infield. A player stands in this zone to throw the ball. It is higher than the rest of the field. The pitcher mound is 60 feet 6 inches (18.4 meters) from home plate.
Базовые показатели
Baselines are straight markings which paint to connect the bases on the diamond. In professional fields, these lines are 90 feet or 27.4 meters long. However, you will find some baselines not painted on the field. These include lines between first & second base and second and third base.
Running Lane
This lane is a special path which you will see near first base. It has a width of 3 feet. You need to mark the running lane with a 45 foot line next to the foul line and first base. Basically, this path helps you to move safely between home plate and first base. You have to stay inside or on the lines of this lane.
Baseball Field Bases
Each base has a size of 18 inch square at the corners of the diamond. Later, they were made bigger around 15 inches in September 2022. The main goal is to keep players safe and reduce collision risks between batters and basemen.
Home Plate
The home plate is actually the base which is designed to complete the diamond. To score a run, you must run around all the bases and then reach home plate. Well, home plate is 90 feet (27.4 meters) from first base on the right and third base on the left. It has a distance of 127 feet 3 inches (38.8 meters) from second base. This way, these bases create a 90 degree angle at home plate.
Batter’s Box
The batter’s box is the area where you (as a batter) should stand to hit the ball. You will find this zone around the home plate. There are two rectangular boxes. Each box is 7 ft (2.1 m) long and 3 feet (0.9 m) wide. Right handed batters can use the box on the left. If you are a left handed batter, you should use the box on the right.
Catcher’s Box
You will notice this zone behind home plate. The baseball ground had two catcher’s boxes. The first box is present near first base and second one close to third base. In professional baseball, the catcher’s box is 43 inches wide and 8 feet long.
Pitching Rubber
The pitching rubber is also known as pitcher’s plate. In baseball ground, it is a white rectangle which is 24 inches long and 6 inches wide. You will find this part at the top of the pitcher’s mound. As a pitcher, you have to touch it with your foot to start your pitch.
Baseball Outfield Dimensions
The baseball outfield is the grassy area which you will see beyond the infield. You can play in the outfield location when a batter hits the ball far from the bases.
Foul Lines in Baseball
These are two straight lines marked across the back of home plate and left/right field foul poles. They indicate the boundary between fair and foul territory. They must be at least 320 ft (97.5 m) long on both sides of the field.
Baseball Center Field Depth
If we talk about center field, it is the deepest part of the outfield. You can measure it across home plate straight to the center field fence. On most adult fields, the center field depth is approximately 400 feet (122 meters). However, some fields can be a bit shorter or longer.
Outfield Wall/Fence
The outfield fence is used to mark the edge of the playground. You can see it at the end of the outfield. The distance between home plate to the fence mostly ranges 300 to 400+ feet (91 to 122 meters). When you hit the ball over this fence in fair territory, you can score a home run.
