Deck plans.
Built from the ground up.
Move from usable space to board rows, framing quantities, stair geometry, fasteners, and a complete-scope budget—with structural limits kept explicit.
All-purpose estimator
Deck Board Calculator
Choose board direction, enter actual board coverage, and translate the surface into rows, linear feet, and whole stock boards.
Calculate deck boards →Calculators
Run the numbers.
Each tool keeps measurements, allowances, package rounding, and costs visible.
Deck Board Calculator
Estimate deck-board rows, linear footage and stock boards using actual width, gap and allowance.
Open calculator →02Deck Cost Calculator
Build an editable deck budget from surface area, local rates, railing, stairs and fixed costs.
Open calculator →03Deck Joist Calculator
Estimate joist count and equalized spacing from deck width, joist run and a verified on-center maximum.
Open calculator →04Deck Stair Calculator
Divide total rise into equal risers, estimate treads and compare projected run with available space.
Open calculator →05Deck Fastener Calculator
Estimate deck fasteners from board rows, joist lines, fasteners per intersection and package size.
Open calculator →Field notes
Measure smarter.
Plan the details.
How Many Deck Boards?
Choose board direction, divide the perpendicular deck dimension by actual installed board coverage, and multiply the resulting rows by each run length.
Read guide →Guide 02Deck Board Spacing
Use the decking manufacturer’s current gap and end-spacing instructions for the exact product and installation temperature; do not apply one universal gap to wood and composite.
Read guide →Guide 03Composite vs. Wood Cost
Compare specified systems—not labels—using decking, substructure, fasteners, fascia, railing, labor, waste, maintenance, repair, warranty, and expected ownership period.
Read guide →Guide 04Deck Size Guide
List the people, furniture, cooking, circulation, doors, stairs, and clearances the deck must support, then test a scaled layout within property and structural constraints.
Read guide →Guide 05Deck Materials List
Organize the takeoff by foundations, posts, beams, house connection, joists, decking, guards, stairs, hardware, water management, finishes, and site work.
