Deck Material Joist and Decking

This decking calculator helps you estimate the required number of joists, beams, and decking boards based on your deck's dimensions and material specifications. It also calculates the lineal footage needed for each component and provides an optional total cost estimation based on material prices. This tool is useful for builders and homeowners planning deck construction projects.

Calculator

1. the length of deck in feet and inches (The distance away from the house in feet and inches)
2. the width of the deck in feet and inches (The joist count is based on the width of the deck)
3. the on-centre spacing of the deck joist (e.g., 12, 16, 24)
4. the number of ply's of the beam
5. the width of the decking board in inches
6. the per lineal foot price of the joist material
7. the per lineal foot price of the beam material
8. the lineal foot price of the decking material

Results

1. the number of joists required (does not include doubling of the end joists)
2. the length of each joist based on the deck length
3. the total lineal footage required for joists (this calculation includes the ledger and the rim joist plus doubling the two end joists for structural stability)
4. the beams in a lineal foot amount
5. the number of decking boards required
6. the lineal footage of decking boards
7. the estimated cost of joists, beams, and decking materials
