Practical Example

Let’s say you are measuring a small apartment room:

• Length: 12 ft
• Width: 10 ft
• Number of Rooms: 2
• Extra Area: 20 sqft

Calculation Breakdown:

• Single Room Area = 12 × 10 = 120 sqft
• Total Rooms Area = 120 × 2 = 240 sqft
• Extra Area = 20 sqft
• Final Total Area = 260 sqft

Result Category:

Since 260 sqft falls between 150 and 400 sqft, the tool classifies it as a Medium Room.

This makes it easy for homeowners and designers to quickly understand space usage.
