Who we are
This site is run by a small editorial team that cares about one thing: helping you plan a deck project with realistic numbers before you spend money on materials. We are not tied to any board manufacturer or hardware chain, and we have no products to sell you. The calculator and the articles exist to make the planning stage easier and the shopping list more accurate.
What the calculator does
The calculator estimates how many linear meters or feet of deck boards your project needs, and roughly how many screws to buy. It works from the inputs that actually drive material quantities: the deck area, the width of the boards you are considering, the gap you plan to leave between them, a waste allowance for cuts and offcuts, and the spacing of the joists underneath.
Change any of those inputs and the estimate updates, so you can compare board widths or test how much a tighter gap really saves before you commit to anything.
How to read the numbers
Every figure the calculator produces is an estimate meant for planning, not a final order sheet. Our assumptions are based on common industry practice and the rules of thumb professionals use, but products differ. The installation instructions from your board and screw manufacturer always take precedence over our general guidance, on spacing, fastening patterns, and everything else.
Use the calculator to get a solid starting point, check it against the products you actually plan to buy, and you will walk into the lumber yard with far fewer surprises ahead of you.
