A football field is approximately 0.0000175 square miles. This calculation is based on the standard dimensions of an American football field.
So, how many square miles is a football field? It’s a tiny fraction, and we’ll break down exactly why and how we get to that number. Many people wonder about the sheer scale of a football field, especially when thinking about larger units of measurement. While we often think of football fields in terms of yards or feet, converting that to miles helps put things into a different perspective.
This article will delve deep into the football field dimensions in acres, the area of an American football field, and football field size in square feet. We’ll also touch upon the dimensions of a soccer pitch for comparison and explore how big is a football field in various units. Finally, we’ll look at the football field length and width and the different football field measurement units used.

Deciphering the Football Field’s Size
When we talk about a football field, we’re usually referring to the playing area itself, not including the end zones or the sidelines. However, official regulations often include these areas. For the purposes of this discussion, we’ll stick to the most commonly accepted playing field dimensions.
The Standard Dimensions
The National Football League (NFL) and NCAA (college football) have standardized dimensions for their fields. These are crucial for fair play and consistent competition.
- Length: The playing field itself is 100 yards long.
- Width: The field is 53.3 yards wide.
It’s important to note that these are the dimensions of the gridiron, the actual playing surface where the ball is in play.
Converting Yards to Feet
To get a better sense of the size, let’s convert these measurements into feet, as feet are a more commonly used unit in everyday life.
- 1 yard = 3 feet
Therefore:
- Length in feet: 100 yards * 3 feet/yard = 300 feet
- Width in feet: 53.3 yards * 3 feet/yard = 160 feet (approximately, as 53.3 yards is often rounded from 160 feet)
So, the playing area of a regulation football field is 300 feet long and 160 feet wide. This gives us the core figures to calculate the area.
Calculating the Area of an American Football Field
Now that we have the length and width in feet, we can easily calculate the area. The formula for the area of a rectangle is:
Area = Length × Width
Using our figures:
- Area of an American football field: 300 feet × 160 feet = 48,000 square feet.
This figure represents the playing area itself.
Including End Zones
However, American football fields also have end zones at each end. Each end zone is 10 yards deep.
- End zone depth in feet: 10 yards * 3 feet/yard = 30 feet
So, each end zone is 160 feet wide and 30 feet deep.
- Area of one end zone: 160 feet * 30 feet = 4,800 square feet
- Total area of both end zones: 4,800 sq ft * 2 = 9,600 square feet
If we include the end zones, the total length of the field becomes:
- Total length with end zones: 300 feet (playing field) + 30 feet (end zone 1) + 30 feet (end zone 2) = 360 feet
The total area, including the end zones, is:
- Total area with end zones: 360 feet * 160 feet = 57,600 square feet.
For consistency and often when discussing the “field,” we’ll focus on the playing area of 48,000 square feet unless specified otherwise.
Football Field Size in Square Feet
To reiterate, the football field size in square feet for the playing area is 48,000 square feet. When including the end zones, it expands to 57,600 square feet.
Converting to Other Units: Acres and Square Meters
The question specifically asks about square miles, but it’s useful to see how the field’s size translates into other common units like acres and square meters.
Football Field Dimensions in Acres
An acre is a larger unit of area, commonly used for land measurement.
- 1 acre = 43,560 square feet
Now, let’s see how our football field measures up:
- Football field in acres (playing area only): 48,000 square feet / 43,560 square feet/acre ≈ 1.10 acres
So, the playing area of an American football field is just over 1 acre.
- Football field in acres (including end zones): 57,600 square feet / 43,560 square feet/acre ≈ 1.32 acres
This gives us a good benchmark for comparing the field’s size to familiar land areas.
Square Meters of a Football Field
In metric countries, area is often measured in square meters.
- 1 foot = 0.3048 meters
- 1 square foot = (0.3048 meters)^2 ≈ 0.092903 square meters
Let’s convert our football field dimensions:
- Length in meters: 300 feet * 0.3048 meters/foot = 91.44 meters
- Width in meters: 160 feet * 0.3048 meters/foot = 48.768 meters
Now, the area in square meters:
- Square meters of a football field (playing area): 91.44 meters * 48.768 meters ≈ 4,461 square meters
If we include the end zones:
- Total length in meters (with end zones): 360 feet * 0.3048 meters/foot = 109.728 meters
- Square meters of a football field (including end zones): 109.728 meters * 48.768 meters ≈ 5,354 square meters
The Ultimate Conversion: Square Miles
Finally, we arrive at the core question: How many square miles is a football field?
First, we need to know the conversion factor between square feet and square miles.
- 1 mile = 5,280 feet
- 1 square mile = (5,280 feet)^2 = 27,878,400 square feet
Now, we can perform the calculation for the playing area of the football field:
- Square miles in a football field (playing area): 48,000 square feet / 27,878,400 square feet/square mile
Let’s do the math:
48,000 / 27,878,400 ≈ 0.00172176
Therefore, the playing area of an American football field is approximately 0.00172 square miles.
If we consider the total area including the end zones:
- Square miles in a football field (including end zones): 57,600 square feet / 27,878,400 square feet/square mile
57,600 / 27,878,400 ≈ 0.002066
So, including the end zones, it’s approximately 0.00207 square miles.
It’s clear that a football field is an incredibly small fraction of a square mile. To put it in perspective, you would need over 58,000 football fields (playing area only) to cover a single square mile.
Comparing with Soccer Pitch Dimensions
It’s helpful to compare the dimensions of a soccer pitch to an American football field to appreciate the differences in scale and sport design. Soccer, or football as it’s known globally, is played on a much larger field.
FIFA (Fédération Internationale de Football Association) regulations specify a range for soccer pitch dimensions:
- Length: Minimum 100 yards (90 meters), Maximum 130 yards (120 meters)
- Width: Minimum 50 yards (45 meters), Maximum 100 yards (90 meters)
For international matches, the dimensions are more specific:
- Length: 110-120 yards (100-110 meters)
- Width: 70-80 yards (64-75 meters)
Let’s take a common international size for comparison: 115 yards long by 75 yards wide.
- Length in feet: 115 yards * 3 feet/yard = 345 feet
- Width in feet: 75 yards * 3 feet/yard = 225 feet
Now, let’s calculate the area:
- Area of a soccer pitch: 345 feet * 225 feet = 77,625 square feet
Comparing this to an American football field’s playing area of 48,000 square feet:
- A soccer pitch is significantly larger than an American football field. It’s roughly 1.6 times larger in terms of area.
Let’s convert the soccer pitch area to square miles for a direct comparison:
- Square miles in a soccer pitch: 77,625 square feet / 27,878,400 square feet/square mile ≈ 0.00278 square miles.
This highlights that while both are playing fields, their sizes are quite different, catering to the distinct demands of each sport.

The Concept of “Field”
It’s important to consider what “football field” refers to. When people ask “how many square miles is a football field,” they usually mean the playing surface. However, stadium footprints, including seating, concourses, and other facilities, are vastly larger. A full stadium can cover many acres, but that’s not what’s being measured here.
The Importance of Standardized Measurements
The standardization of size of a regulation football field is critical for the integrity of the sport. It ensures that:
- Fair Competition: All teams play on a field of the same dimensions, removing any environmental advantages related to field size.
- Player Safety: Uniform dimensions help in designing plays and understanding field boundaries, contributing to player safety.
- Coaching and Strategy: Coaches and players develop strategies based on specific field dimensions, including the distances for plays, kicks, and defensive formations.
- Equipment and Field Maintenance: Manufacturers and groundskeepers know the exact specifications for field marking and maintenance.
