Example Calculation

Let’s say you have a room with the following dimensions:

Length: 20 ft
Width: 15 ft
Height: 10 ft

Step 1: Calculate Floor Area
Floor Area = Length × Width = 20 × 15 = 300 sq ft

Step 2: Calculate Wall Area
Wall Area = 2 × Height × (Length + Width) = 2 × 10 × (20 + 15) = 2 × 10 × 35 = 700 sq ft

Step 3: Calculate Ceiling Area
Ceiling Area = Floor Area = 300 sq ft

Using the Floor Plan Calculator, these calculations are performed instantly, saving you time and reducing the chance of error.
