How much will fit on my gobo??

That is a question that comes up almost everyday when working with custom gobos. The problem is that each lighting instrument that projects gobos takes it’s own unique gobo size, and because sizes are different, some gobos can fit much more, or a larger design, than others can. There are 0ver 75 different gobo sizes and each fixture takes it’s own unique gobo size. Gobo sizes are usually refered to with a corresponding letter, like A size, B size, D size, or even Q size. If you do not know the name or the size of gobo you need, the two sizes that you will need are, the OD (outside diameter), and the IA (image area), the IA is where the design will be placed on the gobo. For example, A size gobos have a 100 mm OD, and a 75 mm IA, but the Q size gobo for the GoboMan projectors, has only a 22mm IA,and a 49 mm outside diameter, so obviously the A size will fit much more and a larger design than the Q size gobo. That said, you can still get up to 13 letters on a Q size gobo depending on the font used. You don’t want to try to get to much on a gobo because you can end up with tiny letters that don’t project a lot of light .
