How to measure a house for siding (the reliable method)Measure a house for siding the way an estimator does: walk the perimeter, take the smallest wall height, add the gable triangles, subtract the openings.How much siding do I need? (squares, area & waste explained)How much siding you need in one number: net wall and gable area, times a waste factor, over 100, rounded up to whole squares. Formula, example and edge cases.What is a “square” of siding? (and how many you need)A square of siding is 100 square feet of coverage. Here is why the trade prices by the square, how it maps to boxes and bundles, and how to convert your area.Siding waste factor — how much extra to buyThe siding waste factor explained: why 10–15% is standard, what pushes it higher, and how it changes your square and box count. With a worked example.Vinyl vs fiber cement vs wood vs metal siding (cost, lifespan, maintenance)Compare vinyl, fiber cement, wood/cedar, engineered wood and metal siding on installed cost, lifespan and maintenance, with labeled bands and how to choose.How much does it cost to side a house?

The line items, a worked example and how to split them.Fiber cement (James Hardie) siding cost & coverageFiber cement / James Hardie siding cost and coverage: the installed band, why labor is a bigger share, how to count planks per square, and a worked example.Board & batten and cedar shake siding — quantity & costBoard & batten and cedar shake siding: how to count boards, battens and bundles, why the waste factor runs higher, and a worked example for each pattern.Soffit, fascia & siding trim explainedWhat soffit, fascia and siding trim are, how to measure and price them by the linear and square foot, and where the gutter stops and the siding trade begins.House wrap & weather barrier — how much you needHow much house wrap you need under siding: the roll-count formula, why the overlap allowance matters, a worked example, and why the barrier is required.Re-siding vs repair vs painting — cost & when to do whichRe-siding, repairing or painting existing siding: how the three compare on cost and scope, when each makes sense, and why tear-off changes the re-side math.How to read a siding contractor’s quote (DIY vs pro, what’s in the price)How to read a siding contractor quote: derive the implied price per square foot, check it against labeled bands, spot missing line items, and read the number.
