-Size of your Led Wall: Led walls come in all kinds of sizes. The answer to this question depends mostly on your space. You don’t want too small of a screen, nor would you want too big of a screen in a smaller venue. The next important question to answer is how much space do you have on your stage? -Should I use indoor or outdoor Led? Weather often plays a huge factor when deciding if your led wall should be indoor or outdoor. Sometimes you want to avoid hot weather or humid conditions. Indoor led walls, most of the time, are non-weatherproof and have a smaller pixel pitch, while outdoor led walls tend to be larger with a higher pixel pitch and most important, weatherproof. – Which pixel pitch will you need? Pixel pitch dictates how the picture appears based on the person’s viewing distance from the screen. This is calculated by measuring the millimeters of two pixels of the led screen. For a large Led wall you will need a higher pixel pitch, while lower pitches are better for closer viewing distance.
