Tailors measure only to the bottom of where the boys hang, and the difference for someone gifted (Arnold Palmer enters the discussion) the difference could well be 2.5". I also believe you need to be barefoot when doing this?
By big I am thinking top to bottom. It should be around 1” thick.
I will stand either barefoot or in socks against a wall on a hard floor against a wall with the bottom of the book against the wall to keep it square and the spine against my crotch firmly.
I tried using a standard size hardcover book. Alone. It didn’t work.
