Vinyl Siding and Metal Siding prices are based per square foot. In siding, a square is a 10 feet by 10 feet area. So, one square covers a 100 square foot area on the side of your house.
Prices for siding can range from $150 to $400 per square, installed. $150 is the very simple, cheaper Dutchlap siding. Most people go with the Centerlock or Charter Oak (shown below). See color options here.
