Lumber Calculator

Our lumber calculator helps you determine how many studs and plates you need for framing walls. Whether you're building an interior partition or framing an addition, this tool calculates the number of studs based on your wall length and standard on-center spacing.

The calculator accounts for top and bottom plates (the horizontal members that studs attach to) and includes end studs. It also provides an estimate of total board feet to help you compare prices between suppliers who may price lumber differently.

This tool is perfect for DIY homeowners planning framing projects, contractors preparing material lists, and anyone asking "how many studs do I need for a 20-foot wall?" Remember to add extra studs for corners, door/window king studs, and cripple studs.
