How to figure square footage on your baseball field

How do I figure square footage
of a baseball field or softball field for turf and infield skin?
 

 
Figuring out square footage for your baseball field is required when it comes to using the right amount of seed, fertilizer, or baseball dirt.

Here are three pictures - that may be all you need.  And then the explanation that will allow you to figure out square footage areas whatever your field size is.

And now, the explanation for how to figure this out yourself...

Figuring out square footage is required when it comes to using the right amount of seed, fertilizer, or baseball dirt.

It is a math problem based on the area of a circle. Except that a ball field is one fourth of the circle with another fourth of a circle within it. And on a grass infield you have a square within that smaller wedge.

Use a little league field with a 60 foot length base path as an example.

The homerun fence is 200 feet away from home plate. Home plate usually is at least 15 feet away from the backstop fence behind the plate. So, the distance from the backstop to the homerun fence is about 215 feet. The area of the ball park is one fourth the area of a circle with a radius of 215. Area of a circle is pie X radius squared. So, you have A = 215 * 215 * 3.14. This is about 145,000 square feet. Divide by 4 for the area of the ball park. You get about 36,000 square feet for the whole ball park. This is about three fourths of an acre.

Home to pitcher mound is 46 feet. Pitcher mound to back of infield dirt is 50 feet. Now this is where you have bit of a fudge factor. Do you have grass on the foul area side of your base path or is it dirt? If it is dirt, then from the backstop to the back of the infield dirt is 15 + 46 + 50. 111 feet. Do the math for a circle with a radius of 111 feet. A = 111 x 111 X 3.14. This is about 39,000. Divide by 4. This is about 10,000 square feet for the area that includes the infield dirt and turf. It is OK to round these off to make the math easier.

Next, the infield turf area. Base paths are 60 feet long and are typically 3 feet wide. This means the grass area is a square that is 54 feet by 54 feet. So, the infield grass area is about 2900 square feet. It is really less than that when you account for the base cutouts and the mound, but for planning purposes this number is close enough.

To be technical with this, the mound area is 5 x 5 x 3.14 = about 80 square feet.

Now we subtract the infield turf area (2900) from the entire infield turf / dirt area (10,000) for the area of the dirt. This gives you about 7,000 square feet for the dirt area. This assumes no grass on the foul area between home and the bases.

If you have grass on the foul area by third and first, then the areas change by about 2000 feet. You have 5000 square feet of dirt and about 5000 square feet for turf (2000 for foul area between home and bases and about 3000 for the infield turf).

Either way, the area of the outfield turf is 36000 – 10000 = 26,000. You have 26,000 square feet of outfield turf.

This is long. The pictures might be all that you need!
