Deck Board, Lumber and Stair Calculators

Plan surface boards, board-foot quantities, and stair geometry with actual dimensions and explicit limits.

Choose a calculator

Calculate actual board feet, waste allowance, wood volume, and material cost.

Plan riser count, tread count, total run, stringer length, and stair angle.

Estimate straight deck-board rows and stock boards with actual width, gaps, cuts, and board cost.

Nominal wood labels do not always match measured thickness and width.

Complete stock boards must support the intended cutting and joint layout. Linear footage alone can hide waste.

Quantity and geometry tools do not select spans, supports, connections, or compliant stair dimensions.

Estimate deck rows using actual board width and spacing, then convert rows into stock boards without assuming reusable offcuts.
