According to the rulebook, parks built after June 1, 1958, must have **a minimum distance** of **325 feet** between home plate and the nearest fence, stand, or other obstruction on the right and left **field foul lines**, and 400 feet between home plate and the nearest fence, stand, or other obstruction in the center of the field.

Parks built before that date only had to be 300 feet between home plate and any such obstruction. In addition, those older parks that were not built with lights may have had some other requirement for center field, such as a distance of at least 250 feet from home plate to something else (such as the batter's box or pitcher's mound).

All major league stadiums have distances of at least 330 feet between home plate and either corner of the outfield, though many are closer than that. The Boston Red Sox' Fenway Park is the oldest stadium in Major League Baseball (MLB) history and has been called the "granddaddy" of all modern ballparks because it is still in use today after nearly 90 years. It was also the first park in MLB with lights used for night games.

Fenway Park has 30,542 square feet (2,829 m 2 ) of floor space, including 8,374 square feet (749 m 2 ) of standing room only. That's the most of **any MLB stadium**. It's also the largest ballpark in New England by far.

The official regulations do not specify the design, height, or substance of the wall, nor a precise necessary distance from home plate though Major League Baseball specifies a minimum distance of 250 feet (76 m) at the foul poles and 400 feet (120 m) at center field. As a result, baseball fields can differ significantly along those lines. That said, it is estimated that the average length of a baseball field is 400 feet from home plate.

To determine the distance across a baseball field, we first need to know how far apart the bases are. There are two ways to measure this: visually and with mathematics. The visual way is to use the high-water marks on the dirt as your guide. If you stand in the middle of the field and look down, you should be able to see where the water reaches when it rains. Measure from there to the base of each wall and you have measured the width of the playing surface. Now you just have to figure out how far apart the walls are. You could use a compass to draw circles on the ground and estimate **how many degrees** they overlap, but that's probably not the best method since most balls are hit between 90 and 180 degrees from **home plate**. A much easier way is with mathematics. The distance between the centers of the two bases is called the depth of the ballpark. The total length of the ballpark is its radius. So, to calculate the distance across the ball park, all you have to do is multiply the depth by 3.1416..

Remember that your parking lot is also a component of the puzzle. It can quickly use a lot of space. As a beginning point, consider twenty slots... A Ballpark's Space Requirements

BASEBALL FIELD Typical space needs | |
---|---|

90′ bases (400′ fence) | 4.5 acres |

80′ bases (315′ fence) | 3.0 acres |

70′ bases (275′ fence) | 2.0 acres |

60′ bases (215′ fence) | 1.5 acres |

When the right and left fences are added together, the overall circumference of the field is roughly 628.32 feet + 325 feet + 325 feet = 1278.32 feet. A mile is 5280 feet. To cover a mile, one would have to cover **5280/1278.32 = 4.13 perimeters** or circuits of **a baseball field**. That's how we got there in **four laps**!

The distance between **the center lines** of the two bases is 115 feet. So, if we add them together, we get 150 feet + 115 feet = 265 feet. A quarter of a mile is 160 feet. So, to cover a quarter of a mile, one would need to make 16 trips across the infield (or rounds). This gives us 4 rounds or gates of the baseball field.

The area of a baseball field is approximately 95 acres. So, the perimeter of the baseball field is 2.9 miles.

It takes on average 3 minutes 20 seconds to walk the entire length of a football field. It also takes about 5 hours 40 minutes to walk the length of a marathon. Therefore, it should take on average 3 days 20 hours 20 minutes to walk the length of a baseball field.
