Measure from the edge of the book that is pressing into your pubic bone. So, essentially TOP (spine) of the book to floor in stocking feet. You don't want the bike tube to be hitting your pubic bone when you stand over it (even in stocking feet) so you want a bike with a SMALLER standover than your bicycling inseam.
If you don't have a firm book handy, use a board. Cutting board works fine. measure from the edge of the cutting board that is pressing into your pubes to the floor as you stand with your back and heels and end of the board against the wall.
