Step 2: Calculation Options
Material Calculations
Add 10-15% extra material for waste when ordering flooring or paint. For painting, remember to subtract window and door areas for accurate coverage estimates.

Measurement Formulas
Area = Length × Width | Perimeter = 2×(Length+Width) | Volume = Length×Width×Height
For rectangular rooms: Area is calculated by multiplying length by width. Perimeter is the sum of all sides. Volume adds height for three-dimensional space. For flooring, multiply area by cost per unit. For painting, calculate wall area (Perimeter×Height) minus openings.
