Fear not, workshop math is not something to be scared of or avoided; Practical Shop Math covers it all from the basic to the advanced.

By its very nature, woodworking requires a basic understanding of math. Various numbers, in the form of thickness, width, and length dimensions, are used to describe the physical size of a a woodworking project and its component parts. Inevitably, these dimensions –written as whole numbers, fractions, and decimals – must be added, subtracted, multiplied, and divided in order to cut and assemble the project.

Although math is an essential part of woodworking, a surprising number of crafters feel intimidated when working with decimals, fractions, geometry, and formula. Fear not; workshop math is not something to be scared of or avoided. Woodworking involves a lot of math and you’ll be at a disadvantage in the workshop if you don’t know or can’t remember how to do basic calculations. Even if you do know how to work with fractions, decimals, and geometric shapes, this tremendously handy and comprehensive guide from a Tom Begnal, a life-long woodworker and former editor at Fine Woodworking, Woodworker’s Journal, and ShopNotes, will increase your capabilities in the workshop many times over.
