Many different types of screen exist, ranging from the simplest - manual screen, tensioned screen - to the most complex - electric screen with increased luminosity coating, integrated runners with flap valves in the false ceiling, and masking to permit different projection formats (4/3, 16/9, 14/9, etc.)
Standard sizes on the market range from 120 cm to 600 cm wide by an equivalent height.
It is of course possible to add made-to-measure screens to this already very wide range. There is no limit to the size. To date the biggest we have installed was more than 20 metres wide and 8 metres high.
