#### Chapter 1.4

Are there rules to where players can be on a field? What does inbounds and out-of-bounds mean? Get ready to learn about the boundary lines of a football field.

### The Boundary Lines

We've learned in past chapters about the end lines and sidelines. Together, these lines make up the boundary lines of a football field.

You can think of anything inside of the rectangle in the picture above as inbounds. Everything on or outside of this rectangle is considered out-of-bounds.

### Inbounds vs. Out-of-Bounds

So what does inbounds and out-of-bounds even mean? When players are on the field playing football they are always either inbounds or out-of-bounds. There are rules associated with the boundary lines. For example,

### Touching the Lines

What about the lines themselves? Are they considered inbounds or out-of-bounds?

If a player touches any part of the boundary lines or crosses the boundary lines in any way he/she is considered out-of-bounds.

### Catching Plays

In high school and college NCAA football, a player that catches a pass needs to only have one foot inbounds when catching a pass for it to count. In professional NFL football, a player needs both feet inbounds when catching a pass for it to count.

KEY TAKEAWAY: one (1) foot must be inbounds in high school and NCAA college football. Two (2) feet must be inbounds in NFL football.
