​There are a number of things to consider when trying to decide what size screen you should rent:​

- Ceiling Height: You don't want your screen to be too tall or too shorty. Knowing the height of the ceiling of your presentation venue allows you to determine the appropriate screen size.

- Distance from Screen to Audience: You want to make sure that all audience members can see your presentation clearly, without making them strain their eyes. The viewers that are furthest away from the screen will determine the minimum screen width. A screen should be at least as wide as 1/6 of the distance between the screen and the farthest viewer.

- Projector Native Resolution: By knowing your projectors native resolution, you know which aspect ratio to select for your screen. Having this info on hand when you speak with your Tech Travel Agent will be a big help.
