Decking Framing Calculator

Before the first pier goes in the ground, this app counts the whole deck for you — piers, posts, beams, joists, boards and screws — and hands you one material list to take to the timber yard. TWO WAYS TO SET THE SHAPE - Measure in AR: tap the corners in your garden and the edges snap square - Or just type the dimensions: rectangle, L-shape, or your own polygon - No AR device needed — the whole app works from typed numbers THE WHOLE FRAME, NOT JUST THE BOARDS - Piers and posts, counted under every beam - Beams and joists at the spacing you choose - Post height, and the sizes of every member - A section drawing that shows how the five layers stack up BOARDS THE WAY YOU'LL LAY THEM - Aligned joints, or staggered one row at a time - The board count changes with the pattern — and tells you when your deck is short enough that it makes no difference - Board size, length, gap and waste allowance, all editable ONE MATERIAL LIST - Every member with its size and quantity in a single table - Screws by count and by box - Save each deck and re-run it with different specs HONEST ABOUT WHAT IT SHOWS - Quantities are estimates — check key edges with a tape measure. - The app counts materials. It does not judge whether your spacing or sizes are strong enough: follow your local building regulations and the material's own instructions. No account, no subscription, works completely offline.
