I'm not wholly sure, but I believe they reduced significantly over time. The early ones had a whole bunch of extra symbols and ligatured letters (think ae, and a bunch of others that gradually went out of fashion). This was the figure I found for the late fifteenth / early sixteenth century ones. Might also have been a fonts thing?
