Hvad er Deck Calculator?

▾

A deck calculator estimates the decking boards, joists, posts, and fixings needed to build a timber or composite deck. It also estimates the total cost based on material choice.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Sådan Deck Calculator

▾
  1. 1Calculate deck area (length × width)
  2. 2Board count: area ÷ (board width − gap) × board length; add 10% for diagonal or waste
  3. 3Joist spacing: typically 400mm centres; number = deck length ÷ 0.4 + 1
  4. 4Posts: typically every 1.5–2m where frame meets ground

Composite decking (wood-plastic) costs 2–3× more upfront than treated softwood but has a lifespan of 25+ years vs 10–15 years for softwood, making it often cheaper long-term.
