American Football Field Dimensions
American Football Field Dimensions
To people unfamiliar with the game, football is football. Regardless of the type being
played or age of players, the structure is the same, the rules are the same, and the field is
the same. In reality, that’s not an accurate view of football at all. Though they’re subtle,

differences is with the layout of the fields. Below is an overview of the characteristics that
set each of football’s different levels apart; click on the pictures in each section to view
a diagram of the dimensions for each type of field.

The National Football League (NFL) is considered the definitive
form of American Football, although football at the collegiate level
enjoys a healthy audience as well. Being that professional football is
the most popular of all the forms, the dimensions and
characteristics listed below will all focus on an NFL field.
Overall Dimensions: At the professional level, the total size of the field is 120 yards (360
feet) long by 53.5 yards (160 feet) wide; that total length is broken down into 100 yards of
playing field and two end zones that are each 10 yards in length.
Personnel Boundaries: All team personnel members are required to stay within an area
marked by two ‘Restraining Lines’ at each 30-yard line, and behind the six-foot-wide area
that marks the boundaries. This is the area where players, coaches, staff, etc. must remain
for the duration of the game.
Markings: The lines marking the playing area (side lines, goal lines, lines at the back of
the end zone) are all four inches wide. A solid white border, six feet in width, surrounds the
end zones to mark the boundaries. This border usually extends along both sidelines and
encompasses the lines marking the playing area. It is common for each team to have their
logos painted at the exact middle point of the field, and a similar design in the end zones.
Regardless of the design, the only rule regarding non-measurement markings on the field
is that they must be approved by the NFL.
Solid Yard Lines: Starting at each goal line and moving inward, there are solid
lines painted every five yards that run the width of the field; the smaller individual
lines representing single yards are placed at one-yard intervals between these solid
lines.
Individual Yard Lines: Because progress is measured in yards, the lines
indicating individual yards are the most important.There are four sets of small lines
(2 feet in width) that indicate each yard between both goal lines and the exact
middle of the field at the 50-yard line. Of those four sets, two are always placed
four inches in from both sidelines, and the other two are placed at 70 feet, 9 inches
in from each sideline.
Field Numbers: Every ten yards, numbers measuring 4 feet wide by 6 feet high

indicate the distance of each of these lines from their respective goal line. The
numbered lines from both ends of the field meet, and end, at the 50-yard line.
Uprights Measurements: Though it's not technically associated with the field dimensions,
the uprights are considered a part of the playing field. In the NFL, the uprights stand from
a goal-post situated at the very middle of the back boundary line of each end zone. The
goal-post crossbar is 10 feet from the ground, with the uprights being at least 20 feet high
and spaced 18 feet, 6 inches apart.
Collegiate Football
Football at the college level is played on a field that looks almost exactly the same as a
standard NFL field. The size of the field is the same, as are the goal-post and uprights.
The dimensions and markings are the same with one exception: The inside set of hash
marks (those not touching the sidelines) are situated differently, resting 60 feet in from
each sideline rather than at 70 feet 9 inches.
High School Football
In terms of overall size and boundaries, a high school football field
is also almost the exact same as an NFL field. However, just like on
a college field, the inside pair of hash marks are positioned
differently; at the secondary grade level, they sit 53 feet, 4 inches in
from each sideline. The only other difference is in the spacing of the
uprights posts; while the distance between them measures 18 feet,
6 inches in both professional and collegiate football, at the high school level they are 23
feet, 4 inches apart.
Youth Football Modifications
Sometimes youth football is played on a smaller version of a normal
High School field. Different places have different qualifications for
“Youth,” but it’s usually any team that fields players not yet in a
secondary grade, usually either sixth or seventh grade. When
modifications are made, the following field measurement changes
are simply marked off with the help of pylons or cones:
The length of the field is 80 yards, and the width is 70 feet, not yards.
The end zones are eight yards deep.
Because of the shortened length, the middle of the field is the 40-yard line, not the
50.
These are ust a few of the possible modifications that get made for younger football
players. Exact field dimensions and specifications will vary according to the different youth
football leagues/organizations that exist, as well as the specific age of the players.
Arena Football
While technically still a branch of American football, Arena football
has a unique set of rules, especially regarding the field on which it’s
played.
Overall Dimensions: Unlike a normal football stadium (which can
be indoor or outdoor), Arena football is played exclusively indoors,
in venues where basketball and hockey are commonly played. In fact, if you were to make
a hockey rink completely rectangular in shape, it would be the exact same size as an
Arena football field: 66 yards long (50-yard field, 8-yard long end zones) by 28.5 yards
wide.
There are two big differences between Arena football and all other types: Boards and field
size. The field itself is only 50 yards long, literally half as long as other fields, and
surrounded by boards. These boards are technically referred to as ‘sideline barriers.’ They
are 4 feet high, and must be covered in league-approved, high-density foam padding.
Uprights Measurements: Another big difference deals with the uprights, and specifically
how missed field goals are handled. Unless it is physically blocked by a player, a missed
field goal in other types of football means the play is over. In Arena football, however, the
uprights (which measure 9 feet high by 15 feet wide) are flanked on both sides by two taut
‘rebound nets.’ If the ball bounces off these nets, it is considered live and can be played by
either team.
Markings: Other minor differences are with the size of the numbers on field (3 feet by 18
inches, located 15 feet from the sidelines), and the positioning of the hash marks (outside
sets are 13.5 feet from the middle of the field, inside sets are 4.5 feet from the middle of
the field).
Canadian Football
Canadian football fields share many of the same characteristics as
NFL fields, including the various types of markings found both on
and outside the field, as well as the size and dimensions of the
uprights. However, there are a few significant differences:
Overall Dimensions: The Canadian Football League plays its
games on a larger field than its American counterpart. The total size of a Canadian field is
150 yards (450 feet) long by 65 yards (195 feet) wide, including end zones that are 20
yards deep.
Markings: The on-field markings for Canadian football are very similar to those found on
American football fields, with a few notable exceptions:
Because the field is 110 yards longs, the exact middle of it falls on the 55-yard line,
which is marked by two instances of a ‘C.’
The interior sets of hash marks are placed 24 yards in from both sidelines.
Much like the field, the actual game structure of Canadian football is similar to that of the
NFL, but unique enough to stand on its own.
Ball
Different levels also use a different size of football. Here is a
breakdown of the sizes of football used at each level:
Youth football: Depending on their age, players would use a
Size 1 or Size 3 ball made of rubber or leather.
High school football: Players use a Size 4 ball made of
rubber or leather.
Collegiate, Professional Level, and Arena: The short circumference is 20.75 –
21.25 inches; the long circumference is 27.75 - 28.5 inches; the weight is
approximately 14-15 ounces; the length is 16 inches long; and it is inflated to have
between 12.5 and 13.5 pounds per square inch.
CFL: The short circumference is between 20.875 and 21.125 inches; the long
circumference is between 27.75 and 28.25 inches; it is inflated to hold between
12.5 and 13.5 pounds per square inch; and it should weigh between 14 and 15
ounces.
Differences Aside
These aren’t the only characteristics that distinguish the various types of football from each
other, but they are among the most important and noticeable in a game with very
elaborate rules and regulations. Hopefully you now have a better understanding of the
more distinguishing characteristics that exist between the different levels of the game!

The NFL game appears to be played in a warped space, since the length of the ball is
given as 16 inches, and the long circumference as 28 inches. In our normal 3-D space the
long circumference would have to be greater than twice the length.

It just seems that your grammar and spelling errors are unsatisfactory in my opinion.

Just seems that a high school football field is 3/4 that of a professional field. Maybe if the
field had a 60,000 seating capacity instead of 300. It would seem bigger. But i could swear
the pro ball fields r much bigger.
