ABOUT HOMESIDINGCALCULATOR.COM
A small, focused set of tools — built one at a time, and built properly.
Most siding quotes start with a rough number a homeowner has no way to sanity-check. HomeSidingCalculator.com exists to give U.S. homeowners and contractors a fast, free, private way to estimate materials, waste, and rough cost before a contractor visit — using the same "siding squares" method contractors themselves use to quote jobs.
Why this exists
A calculator you can trust starts with showing its work. Every number here is built from the same math a contractor uses to measure a job — not a black box.
How the numbers work
The calculator measures your wall and gable area, subtracts window and door openings, adds a waste allowance for cuts and mistakes, then converts the result into siding squares (100 sq ft each) and an estimated board count. Material and labor costs shown are rough U.S. national averages, not a quote — actual pricing depends on your region, home condition, and contractor.
What's live today
The general Siding Calculator, plus dedicated Vinyl, Fiber Cement, and Wood calculators, are all live now — each with material-specific board sizing, waste defaults, and cost rates. More material-specific tools are still on the way; see the full calculator list for what's built and what's coming next.
