Siding Cost Per Square
Siding is quoted by the square — 100 square feet — so knowing the per-square cost is how you price and order accurately.
Quick answer: Per square (100 sq ft) installed: vinyl $400–$800, fiber cement $600–$1,200, wood $800–$1,400.
Square vs square foot
One square equals 100 square feet of coverage. Divide a per-square price by 100 for the per-square-foot figure, or multiply per-square-foot by 100 the other way. Ordering in squares is why the unit matters — a small mix-up mis-orders a whole wall.
Turn squares into a total
Multiply your wall squares (with waste) by the per-square price, add trim and labor, and you have a bid. The siding calculator keeps the units straight so the order and the quote match.
