Area Calculator: Feet and Inches

Use the feet and inches calculator to find square footage. Choose to multiply lengths and widths in feet and inches to get results in square feet (ft²) or square inches (in²).

For example, calculate the area of a dog kennel with walls measuring 2 feet 6 inches by 1 foot 5 inches:

• Convert feet and inches to total inches: 1 ft 5 in = 17 in; 2 ft 6 in = 30 in.
• Multiply converted lengths: 17 in × 30 in = 510 in².

This quick method helps accurately determine necessary materials or space planning.

How to Add Feet and Inches?

Add feet and inches by separating the units and summing feet and inches separately:

Example: 2 ft 3 in + 5 ft 6 in

• Feet: 2 + 5 = 7 ft
• Inches: 3 + 6 = 9 in

Result: 7 ft 9 in

Remember to convert inches beyond 12 to feet, as 12 inches equals 1 foot.

Adding Inches with Fractions

When adding inches with fractions, first add whole feet and inches normally, then handle fractions.

Example: 2 ft 10 1/4 in + 1 ft 2 9/16 in

• Add feet: 2 + 1 = 3 ft
• Add inches: 10 + 2 = 12 in = 1 ft, carry over to feet making total 4 ft inches reset to 0
• Add fractions: 1/4 + 9/16; convert to common denominator (16), total 13/16 in.

Final result: 4 ft 13/16 in

Frequently Asked Questions (FAQs)

How should I write feet and inches?

Feet are abbreviated as ft or denoted by a single apostrophe (e.g., 4′). Inches are abbreviated as in or represented by double apostrophes (e.g., 10″).

How many feet are 12 inches?

12 inches equal 1 foot since there are 12 inches in a foot. To convert inches to feet, divide by 12.

How can I write 62 inches as feet and inches?

62 inches equal 5 feet 2 inches. Divide 62 by 12 to get 5 feet remainder 2 inches.

How do I multiply feet and inches?

Convert feet to inches (1 ft = 12 in), add any fractional inches, then multiply. For example, multiplying 4 ft 3/8 in by 2 ft converts 4 ft to 48 inches plus 0.375 inches, totals 48.375 inches, multiplied by 24 inches (2 ft) results in 1161 in².
