Why does the High School and college footballs and field goal posts look different then the NFL?

High School has full striped footballs. College has half striped footballs, and the NFL has no stripes on the football.





The field goal posts at college and high school are shaped like an "H" while the NFL posts are not shaped like an "H".|||the highschools that i know have field goal posts that look like the NFLs|||The striping is a visual aid. All three levels of football are governed by different associations (no, the NFL is not a corporation, but a free-standing association). On a practical level, it's much easier to see a football in the air thrown by an NFL QB because of the mass of professional floodlights that make all fields look liked they're being played on the surface of the sun. Of course HS fields often look like dad is shining a flashlight into a hay field.





Goalposts differ because of economics and updated technology. Most (I would guess virtually all D1 college teams) have the "U on a stick" goalposts like the NFL because it's safer, newer technology. The old "H" goalpost is cheaper. When I say safety I mean less chance of a receiver or db running into the bottom of the posts when there's only one, same reason they moved the goalposts to the back of the end zone years ago.|||There are different governing bodies for the various differnt football leagues. For example, the IHSA, NCAA, and NFL. They all have slightlly different specifications for the footballs. Their respective rules vary as well. many High schools use NCAA spec footballs.





The stripes on the football were originally to show where the offensive and defensive players could line up on the line of scrimmage. The space in the middle was the neutral zone.|||Some highschools have the old H b/c they may be cheaper





I also think the hashmarks in college are a little wider so the angle for kicks are as well|||not all goal posts are diff they look the same like the ones at my school look just like the NFL ones
