Museum visitors don’t want to read a lot. They are standing up; they are usually with family and friends; and they want to go look at more cool stuff. We try to keep our labels down to 50 words or less. (This paragraph has 45.)
Put your main point near the beginning—in the headline if you can. That way, if somebody doesn’t read the entire label, they’ll at least get the main message.
Connect your label to the object by pointing out some feature, and linking your story to that.
Rhyme, rhythm and word play make your label fun to read and memorable.
