Ground Coverage & Setback Calculator
Max footprint after setbacks and the coverage percentage check.
Whichever is SMALLER — the setback rectangle or the coverage percentage — governs your ground floor. Small plots are usually setback-bound; large plots coverage-bound.
Formula
Ground Coverage & Setback Calculator is a free ground coverage for surveyors, civil engineers and property buyers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Ground Coverage & Setback Calculator
Max footprint after setbacks and the coverage percentage check. The calculation implements footprint = (L−front−rear)×(W−2×side); check vs coverage % (Model building bye-laws; local DCR). Whichever is SMALLER — the setback rectangle or the coverage percentage — governs your ground floor. Small plots are usually setback-bound; large plots coverage-bound.
