Ok so something I've never really got to grips with is what leading should you use when you have a title in capitals which goes onto two lines. For instance, using InDesign I might have a title in 48pt and it will default the leading to 57.6pt which is fine for sentences but way to deep for capitals. Even making it 48/48pt seems a bit too much. Is there a rule of thumb to get the visually correct leading? I think great typography plays a big part in design work and I'd like to figure it out once and for all!
