The end zone in American football is 10 yards deep. Each end zone runs the full width of the field, which is 53⅓ yards (160 feet), giving the end zone dimensions of 10 yards by 53⅓ yards. Details:
- Depth: 10 yards (30 feet) from the goal line to the end line. This is true for NFL, NCAA, high school, and most organized American football levels in the United States.
 
- Width: 53⅓ yards (160 feet) across. The overall field length is 120 yards, with 100 yards of play between the end lines and 10-yard end zones at each end, making the end zones 53⅓ yards wide.
 
- Canadian football end zones are deeper (20 yards), but the standard American football end zone depth remains 10 yards.
 
If you’re asking about a specific league (NFL, NCAA, high school) or about Canadian football, I can tailor the measurements accordingly.
