💡 How to Convert Linear Feet to Square Feet
Linear feet to square feet: multiply linear feet by the material width in feet. For example, 100 linear feet of 6-inch-wide boards = 100 × 0.5 = 50 sq ft. To convert back: square feet ÷ width in feet = linear feet.
This conversion is essential for materials sold by the linear foot but needed in square foot coverage, like: flooring boards, siding planks, wall paneling, fabric rolls, and fencing. Width must be converted to feet first (divide inches by 12).
100 linear feet of 6" wide boards = 100 × (6÷12) = 50 sq ft. Conversely, to cover 200 sq ft with 8" boards: 200 ÷ (8÷12) = 300 linear feet.
