Robinson and Wrigglesworth measured how much ink common typefaces use by drawing large-scale samples on a wall and letting the remaining ink levels tell the rest of the story. Check it out:
Sorry to see Helvetica ranking just above Comic Sans, but I have long been a lover of Garamond, especially for mapping.
