 This is the first video in a series on how to play football. As you can probably already tell, we're talking about American football here. Sometimes it's called gridiron football and not association football or soccer. If you know nothing about American football, you're in the right place. So this is football. We're just going to start with the very basics in this video. Take a look at the field itself. What do all these lines and markings mean and numbers mean? We're going to break down and explain all that in this video. The first thing you'll notice is that there's all these little lines on the field. These are each three feet apart. Each one is called a yard line because three feet are obviously one yard. From this line here to this line here, this distance here is going to be 100 yards. This is 100 yards. So typically people say the length of a football field is 100 yards. So that's all this distance in here. You can kind of see in the middle here that that is divided in half by the 50 yard line. Each of these numbers on the field represents the number of yards. So it kind of is counting down. It starts in the middle with the 50 and then 40, 30, 20, 10, and then obviously the same thing on both sides. You could probably tell by now that each side of the field is identical. So we start in the middle with the 50 and then the 40 yard line, the 30 yard line, 20 yard line, the 10 yard line. And all this is counting down to is the two lines on both sides here. And these are called goal lines. So this line right here, this gray one, and then this gray one here. These are called goal lines. Each one is just one goal line. And so what the goal line does is it serves as the separation between the rest of the field and then these two unmarked areas on either side. And so these areas here, this one over here, and then everything inside here. These are called the end zones. So then we have another end zone over here. So the distance of the end zone, we saw this was the field itself was 100 yards. The end zone actually leads to the white line there. This distance here will be 10 yards. And then the same thing on the other side. So we can see the total distance is actually 120 yards with the 10 yard end zones on each side. And then of course we have the width of the field. So from this side line here, this line that goes up the side, and then this line there. These are both called the side lines. And in football, these side lines are out of bounds. So if you step on the side line, you're considered out of bounds, which obviously same as in some sports, different in other sports. Football on the line is out of bounds. The two side lines are 160 feet apart. So that's about 53 yards. And so they're about, it's about, obviously the field is about half. I'll put this in here. It's about half of the width as it is along. Or long as it is wide, whichever way you're looking at it. And so those are all, that's the basic rundown of the football field and how it is laid out. One thing, one term you might hear, it's really nothing special as far as markings on the field or anything like that. But anything inside the 20 yard line. From the 20 yard line to the goal line, and then of course the same thing on the other side is this area here. These are some kind, it's sometimes called the red zone. And that is basically just signaling that the team, as we'll see, when you have the ball and you're on offense, and your goal is to get the ball to the end zone, so that means the team would be going this way. So if the team has the ball inside the 20 yard line, we say they're in the red zone. It's basically just, they're getting close. So of course their chances of scoring are increased when they're that close. So maybe it'll make more sense if you see a picture. So here's a photo of a typical NFL game being played. The NFL stands for the National Football League. That's the highest level of play. At least in the United States. So you can actually see in this picture, the team up top here, these guys, they're on offense. And they're heading here down toward the end zone. What you can see is it doesn't have the yard lines. Here's the yard lines in the 10, in the 20, in the 30. So then the end zone is kind of decorated and usually in whatever the home team's colors are. And then you can see the sidelines. Going down the sideline is the real thick one. So of course we said sideline is out of bounds so they make them real thick. Kind of easier to see because plays will often occur along that sideline. So the red team here that's heading toward the end zone is the offensive team. And then this team back here is on defense. And so they are, as we said, the 20 yard line is here. So they are inside. They're actually inside the red zone in this photo. So that's basically how it's set up. And then one last thing to point out. And those would be the field goal uprights. Sometimes usually called the uprights. You wouldn't call it a field goal. It's what happens when you kick the ball through it. And so these uprights, the uprights are at the end in the back of each end zone. So they would actually be located. You can kind of see the little markings here. They would be from here to here. So we'll get into the point of these. Eventually the ball will be kicked through the uprights. So if the ball does go between the uprights, then that will mean points for the team who kicked it. So that's the basic overview and layout of a football field. And so in the next video we'll start getting into how does this whole game work. So we'll see you then.
