Siding Selection & Planning
The selection / how-to / reference cluster: a material selector, a lifespan & maintenance reference, a how-to-measure-for-siding calculator (smallest of three), an exposure / reveal by material reference, and a coverage-per-square reference. Labeled planning typicals — confirm on the manufacturer's installation instructions and stated coverage; pre-1978 lead paint on old siding follows the EPA RRP rule.
Measure your actual walls and gables and follow the manufacturer’s exposure and installation instructions. Complex layouts, many corners and gables, and shingles or diagonal patterns all use more material — allow extra for waste and trim, and round up to whole squares/boxes/bundles. Coverage per box and exposure vary by product; read the manufacturer’s stated coverage.
Typical published planning values — NOT a certified spec or professional advice. Coverage and exposure vary by product and installation; confirm on the manufacturer’s installation instructions and stated coverage. Moisture, flashing, sheathing and pre-1978 lead paint on old siding are a pro’s call — follow the manufacturer’s instructions, local code and the EPA RRP rule and hire a certified firm; lead-paint abatement, structural and moisture repairs and code certification are not engineered here.
Material Selector ReferencePick a siding material by your top priority — budget, low upkeep, durability, fire resistance, look or lifespan. A labeled planning guide, no brand sold.Lifespan & Maintenance ReferenceTypical siding lifespan in years and upkeep by material: vinyl, aluminum, wood/cedar, engineered wood, fiber cement and steel. Labeled ranges, not a warranty.How to Measure for SidingMeasure a house for siding: walls (perimeter × smallest height) plus gable triangles minus door, window and garage openings for the net area. Round up + waste.Exposure / Reveal ReferenceTypical siding exposure and reveal by material — vinyl double-4/5, cedar shake, fiber cement, wood and metal lap, board & batten — plus coverage per unit.Coverage-per-Square ReferenceConvert siding area into squares, boxes or bundles by material coverage. Enter area and waste; get whole units, rounded up. 1 square = 100 sq ft.
Every Siding Selection & Planning tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table, and works on the walls you measure and the prices you enter from your own quotes. Background reading is in the guides.
