Spine thickness S = number of leaves (blank pages included) × paper thickness (+ endpaper thickness allowance). To get the real paper thickness, measure 10 sheets with calipers and divide by 10. W, H: text block width and height; t: board thickness; k: square (board overhang); f: joint gap; e: turn-in. The same cover formulas apply to perfect binding (flat spine).
Values follow typical workshop practice; measure and adjust on your first book.
