Shelf Board Count Calculator
Count boards for a run of shelves.
How the Shelf Board Count Calculator works
Shelf Board Count Calculator turns wall width inches, shelves, board length inches and waste percent into boards needed. It computes that as total shelf length divided by board length, grown by waste.
Worked example: with Wall width inches 96, Shelves 4, Board length inches 48, Waste percent 0, this tool returns boards needed 8 boards, total shelf length 384 in. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
