| It's largely subjective, though the rules of thumb are pretty well agreed-on.
My church, for example, has ridiculously low ceilings. That makes really only the middle third of the screens usable for lyrics: the bottom third is obstructed by people's heads, and the top third is obstructed for many seats by the main speaker arrays. With room size and screen size considered, that makes for a practical limit of about 3 lines, maybe four in some cases, of text, being about two "lines" of a song. From there, it's all about logically breaking the lyrics down into screens and lines to be the most natural.
Too much text on the screen is information overload and the congregation can get lost. Too little and the words aren't up long enough to read. That's true for lyrics, scripture, anything involving words.
For sermon graphics, the Midnight Oil guys among others pioneered the use of imagery rather than text, hopefully signaling an end to the era of "bad sermon Powerpoints" full of flying bullet points. |
