NFL Football Field Dimensions Guide
Exact NFL Length, Width & Measurement Guide
July 21, 2025
An NFL football field measures 120 yards long by 53⅓ yards wide (360 ft × 160 ft), with two 10-yard end zones and hash marks spaced 18 feet 6 inches apart. Total playing area is 57,600 square feet.
Getting the dimensions right on a professional football field makes a big difference. Accurate measurements help ensure the field is safe, meets league standards, and supports smooth game-day operations. From field width to hash mark spacing, every detail affects how the game plays and how the field is maintained. This guide covers all the standard field specifications and offers practical tips for selecting field covers, sideline tarps, and goalpost padding sized for regulation NFL fields.
Standard Professional Football Field Dimensions
Overall NFL Playing Surface
- Football field length: 100 yards (300 ft) between goal lines.
- Football field width: 53⅓ yards (160 ft) sideline-to-sideline.
- Add two 10-yard end zones for a 120-yard (360 ft) total footprint—commonly cited as 360 ft × 160 ft.
End Zones & Goal Lines
- End-zone depth: 10 yards (30 ft).
- Goal line marks the scoring plane. Goalposts sit on the end line at the back of the end zone, so any full-field cover must extend the full 30 ft beyond each goal line.
Yard Lines, Hash Marks & Sidelines
- Yard lines every 5 yards, stopping 8 inches short of the 6-foot white border.
- NFL hash-mark gap: 18 feet, 6 inches (sits 70 ft 9 in from each sideline)—narrower than college or high-school spacing, affecting seam placement on full-field covers.
Goalposts & Buffer Zones
- Crossbar height: 10 ft above turf
- Inside post spacing matches the NFL hash mark gap at 18 ft 6 in
- Upright height: 35 ft minimum
- Restricted area: A six-foot safety border outside every sideline and end line must stay clear for officials and cameras—ideal real estate for football sideline covers or football goal post padding that meets league specs.
NFL Football Field Size at a Glance
A regulation NFL football field measures 120 yards long by 53⅓ yards wide, with 10-yard end zones and hash marks 18 feet 6 inches apart. The table below converts every key dimension into yards, feet, and meters.
Measurement | Yards | Feet | Meters |
Total field length (with end zones) | 120 yd | 360 ft | 109.7 m |
Playing field (goal-to-goal) | 100 yd | 300 ft | 91.4 m |
Field width (sideline to sideline) | 53⅓ yd | 160 ft | 48.8 m |
End zone depth | 10 yd | 30 ft | 9.14 m |
Hash mark gap | 6⅙ yd | 18 ft 6 in | 5.64 m |
Goal post inside width | 6⅙ yd | 18 ft 6 in | 5.64 m |
Total playing area | 6,400 yd² | 57,600 ft² | 5,351 m² |
Why Accurate Field Dimensions Make a Difference for Covers
Knowing the numbers is only half the work. Translating them into protective equipment that actually fits is where field directors and grounds crews earn their reputation. A cover sized even a few inches off spec leads to corner bunching, seam stress, and sideline trip hazards no head coach wants to see during pregame walkthroughs.
When the football field covers match the NFL's exact 360 ft × 160 ft layout, including the 18 ft 6 in hash mark gap and six-foot sideline buffer, the cover lies flat, stays put in wind, and rolls back into storage without dragging across fresh paint. Full-field covers made from 10-ounce vinyl-coated polyester perform best when the two-foot seam overlaps align with the yard line grid, a small specification detail that compounds into years of additional cover life.
Sideline protection has its own dimensional logic. Mesh sideline tarps cut to 120 yards by 6 feet roll out smoothly across the team box and retract without smudging paint. Goalpost pads at six feet tall and 18 inches in diameter absorb impact during return play while keeping officials' sight lines clear.
Get the measurements right from the start, from grommet spacing to seam placement to custom team graphics positioning, and you'll see fewer on-site adjustments, longer-lasting covers, and a field that stays game-ready all season.
NFL vs NCAA vs High School Football Field Dimensions Compared
NFL, NCAA, and NFHS high school football fields share the same 120-yard length and 53⅓-yard width, but hash mark spacing and goal post width vary by level. Flag football and youth tackle fields use smaller footprints entirely.
Level | Total Length | Width | Hash Mark Gap | Goal Post Width |
NFL (Professional) | 120 yd | 53⅓ yd | 18 ft 6 in | 18 ft 6 in |
120 yd | 53⅓ yd | 40 ft | 18 ft 6 in | |
120 yd | 53⅓ yd | 40 ft | 23 ft 4 in | |
70 yd (50 yd goal-to-goal) | 25 (30 yd tournament) | None | None | |
80 yd | 23⅓ yd | None | Varies by league |
Takeaway: All three top-tier formats (NFL, NCAA, NFHS) share the same 120 × 53⅓ yard footprint. The tighter NFL hash-mark gap (18 ft 6 in vs 40 ft for NCAA/NFHS) changes run-and-pass angles, kicker targeting, and field cover seam layouts. End zones are 10 yards at all tackle levels; flag and youth fields shrink to 8-yard end zones in most layouts.
How to Measure an NFL Football Field
- Gather a 300-foot tape or laser meter, chalk line, and two ground stakes.
- Measure from the inside edge of one goal line pylon to the far goal line.
- Mark the 50-yard line and use the 3 4 5 triangle method to square all corners.
- Measure 70 ft 9 in in from each sideline to position the hash mark stripes, then chalk a 4-inch hash at every yard line.
- Record all measurements in a spreadsheet and share with your fabricator for a smooth, wrinkle-free fit.
Recent NFL Rule Updates Affecting Field Layout
- No Dimensional Changes: NFL football field dimensions remain unchanged in the current season.
- Dynamic Kickoff Goes Permanent: Touchbacks now start at the 35, tightening kickoff alignment boxes.
- Hawk-Eye First-Down Tech: Laser-true measurements replace chains, demanding unobstructed sight-lines along hash marks.
Accurate field dimensions go beyond meeting league requirements. They simplify grounds crew work, support player safety, and keep your field looking its best all season.

Frequently Asked Questions
How long is a football field?
A regulation NFL football field is 120 yards (360 feet) long, including both 10-yard end zones, or 100 yards (300 feet) from goal line to goal line.
How many feet is a football field?
360 feet long, including both end zones, or 300 feet from goal line to goal line. The field is 160 feet wide from sideline to sideline.
How wide is an NFL football field?
53⅓ yards, or 160 feet, from sideline to sideline. The width is identical at the high school, college, and professional levels.
How many yards is a football field?
120 yards total — 100 yards of playing field plus two 10-yard end zones. The width is 53⅓ yards.
How big is an NFL football field?
A regulation NFL field covers 57,600 square feet of playing surface (6,400 square yards), measured 360 feet by 160 feet, including both end zones.
How far apart are the hash marks on an NFL field?
18 feet 6 inches — the narrowest hash mark spacing of any football level. NCAA and high school fields use 40-foot spacing by comparison.
Can one cover size fit both NFL and college football fields?
Overall length and width match, but the wider NCAA hash marks shift seam placement. Order covers cut for each level to avoid wrinkles and premature wear.
Do field dimensions affect the type of turf cover I need?
Yes. An oversized tarp wrinkles and risks tearing; a too-small tarp won't reach the edges. Measure first, then order a custom football field cover sized to NFL specifications.
