BindingCalc Book Cost Kit2026

BindingCalc is an offline calculation tool for handmade books, mockups, photo books, portfolios, and small batch book production. It helps you check trim size, page count, paper thickness, spine width, full cover spread, greyboard usage, cover cloth allowance, and per-copy cost before making a book, reducing repeated trial and material waste. The app requires no login, no network connection, and collects no user data. All projects, templates, and calculation records are stored locally on your device, making it useful for personal craft work, independent publishing, design students, pre-print estimates, and early studio quotations. Core features include spine thickness calculation, cover spread sizing, greyboard and cloth material estimates, paper weight and page count templates, per-copy cost breakdown, quantity comparison, project plan saving, common binding templates, local search, and offline export.
