A normal blank for a stock with a cheek piece is 2 1/4 inches thick. A blank that is 1 7/8 and 2 inches would be considered a thin blank and would work on rifles without a cheek piece or a smaller check piece and some shotguns. Also on our website we listed a few extra-thick blanks under rifles and mannlichers. These are 2 1/2 inches and thicker blanks. I will also list blanks that are 2 7/16 inches thick since it is only 1/16 less than 2 1/2 inches. The woodcutters do not like to cut thicker blanks due to the loss of how many blanks they are able to yield from a tree.
