Frequently Asked Questions

How do you calculate square feet from feet and inches?

Convert inches to feet by dividing by 12 (e.g. 6 inches = 6/12 = 0.5 ft). Add that to the feet portion (12 ft + 0.5 ft = 12.5 ft). Multiply total length in feet by total width in feet to get square feet.

How much extra square footage should I buy for wastage?

For straight flooring or tile installations, add a 5% to 10% wastage buffer. For diagonal, herringbone, or complex room shapes with multiple corners, add 10% to 15% extra.

How many Square Feet are in 1 Gaj (Square Yard)?

1 Gaj (Square Yard) is exactly 9 Square Feet (3 feet × 3 feet). To convert Square Feet to Gaj, divide the square feet by 9.

How do I convert Square Feet to Square Meters?

Divide the square footage by 10.7639 (or multiply by 0.092903). For example, 1,000 sq ft is approximately 92.9 m².
