Choosing the correct projection screen size for your event
You have heard the saying “it’s always better on a big screen”. That is not necessarily the case, there are a few things to take into account when deciding which size screen(s) to use for your event. For the best results you need a screen that is big enough so those in the back row can read the subject matter easily, but not so large as to overwhelm the closest viewer. Here is a few pointers to help guide you:
- Distance from the screen to the audience?
The general “rule of thumb” is that the width of the screen should be a fifth of the distance between the screen and the farthest audience member. For example if the back row of venue is 15m from the screen, the screen should be 3m wide.
- Aspect Ratio?
This determines the height of the screen. The most common aspect ratio is 4:3 and is the same as standard television picture. Alternatively you can project in 16:9 wide screen format, provided that the content is in the correct format to avoid stretching.
- Height of the venue ceiling?
The lower part of the screen should be visible from all seats and should ideally be 1.2m from the ground. This is not always possible in a venue with a low roof. For example if the ceiling height is 2m and the screen height is 1.7m the bottom of the screen will be 30cm off the ground and audience members in the back rows won’t be able to see the lower part of the screen. Consider using multiple smaller screens in these situations.
- Other considerations?
A projection screen is not always the best choice. There are instances where there is not enough space, in terms of ceiling height or projection distance, or the venue can’t be darkened sufficiently to allow for projection. In these cases flat screens are a better option.
