Episode 104: The Width of the World

When it comes to putting a book together there are quite a few things that perplex me. The one that constantly perplexes me is the width of the book boards for the front and back covers. I've run across a few formulas and they, of course, all differ.
Formula One: The width of the textblock plus the square of the book minus the thickness of the book board times two. Whew. So, a textblock that is 12 cm wide and a square of the book at 2mm with 2mm-thick book boards would result in: 120 + 2 - 4 = 118.
Formula Two: The textblock - 2mm. In the example above the 120 - 2 = 118. Same answer as above, eh?
Formula Three: The textblock + the square of the book - the hinge. The hinge is either 3.5 times the thickness of the book board or 2 times the thickness of the book board, depending on who you ask. So, in our example:
(Hinge = 3.5 x) 120 + 2 - 7 = 115. Or, (Hinge = 2 x) 120 + 2 - 4 = 118. Hmm. There seems to be a consensus of 118, if you follow the 2 times the board thickness.
Personally, I'm not sure which is best but I always go for the simplest to remember. In this case that would be the textblock - 2 mm. (If the board is 2 mm thick.) I hope if there is a simpler or more accepted formula, someone can teach me but so far I think I'll have to stick with the minus 2 mm for my width measurements.
