Quick calculations for early project review.

Four straightforward tools for preliminary area and coverage checks. Inputs, assumptions and formulas remain visible so contractors can understand the result.

Preliminary guidance only: These tools provide preliminary estimating guidance only and do not replace a full drawing-based quantity takeoff. Verify dimensions, specifications, deductions, waste factors and procurement requirements before relying on any result.
01

HOW THE NUMBERS WORK

Simple formulas.
No hidden pricing.

Area calculators multiply the stated dimensions. Drywall deducts the entered opening area. Paint uses the room perimeter, wall height, opening deduction, coat count, waste and coverage rate. Results do not include drawings, finish schedules, product rules, labor, local pricing or field conditions.
