Square Footage Calculator
A square footage calculator measures total floor and wall area in square feet and square yards from room length and width dimensions. Built to estimate home remodeling materials, it sums multiple rooms into a single tally, showing that a 12-by-15-foot room contains exactly 180 square feet.

How Do You Calculate Square Footage Step by Step?
A bedroom measuring 14 feet 6 inches by 12 feetLength: 14.5 ft
Width: 12 ft
Cost/sq ft: $4.50
Area: 14.5 ft × 12 ft = 174 sq ft
In square yards: 174 ÷ 9 = 19.33 sq yds
Cost estimate: 174 × $4.50 = $783.00
Final Solution:174 sq ft ($783.00 at $4.50/sq ft)
