About MyShopCalc
Built for the shop
MyShopCalc is a suite of free workshop calculators for woodworkers, cabinetmakers, and anyone who thinks in tape measures. Cabinet doors, board feet, deck spacing, stair stringers, miter angles — the math you reach for mid-build, without opening a spreadsheet.
Fast and private by design
Every calculator runs entirely in your browser. Open a page, type a dimension, and the answer appears instantly. Nothing you enter is uploaded, nothing is stored on a server, and there is no account to create. Pages are built as static files, so they load quickly and even work offline once visited.
Fractions, not spreadsheets
Shop results are rendered twice: the exact decimal when you need precision, and a clean fractional cut size to the nearest 1/16" and 1/32" when you're standing at the saw. Fractions are reduced to lowest terms automatically, so you'll never see "14 6/16"" when you mean "14 3/8"".Shop results are rendered with exact decimals when you need precision, giving you precise millimeter measurements when you're standing at the saw.
