Buying too little may leave your room unfinished, while buying too much leads to unnecessary expenses. That’s where a Carpet Measurement Calculator becomes an essential tool.

Practical Example

Imagine you’re carpeting a living room:

• Room Length: 15 ft
• Room Width: 12 ft
• Wastage: 10%
• Carpet Price: $3.00 per sq.ft

Calculation:

• Room Area: 180 sq.ft (15 × 12)
• Total Area (with 10% wastage): 198 sq.ft
• Carpet Needed: 198 sq.ft
• Estimated Total Cost: $594

So, for your living room project, you should budget for approximately $600.
