It answers one question: how much siding and trim does this house need? A 40 by 30 ft one-story house with two gable ends at 6 in 12, 8 windows and 2 doors comes to 13.01 squares with 10 % waste: 157 panels of double 4 in vinyl in 7 cartons, 13 starter strips and 21 pieces of J-channel (open this house in the calculator).
What it counts: wall and gable area, windows and doors, waste, squares, pieces, vinyl cartons, starter strip, J-channel around openings and gable rakes, and corner posts. What it does not count: soffit, fascia, F-channel and undersill trim, and it gives no prices.
Where the numbers come from: the rules are taken from the published estimating guides and coverage charts of the Vinyl Siding Institute, CertainTeed, LP, Ply Gem, the Western Red Cedar Lumber Association and others. Where those sources disagree, the rule we chose is marked on How we calculate with the others beside it. The calculator and the tables in the guides come from the same tested functions.
CladCount is not affiliated with any siding maker or store. Brand names appear only as the publisher of a chart or a number we cite; we do not recommend products. Nobody here writes reviews or collects ratings.
Your measurements stay in your browser: the arithmetic runs on your device, and a copied link carries the numbers only after the # sign, which browsers do not send to servers (see the privacy policy). If a number looks wrong, the contact form reaches the person who maintains the site.
