A 10x16 deck covers 160 square feet and costs about $2,816 – $4,400 installed in pressure-treated pine, up to $6,144 – $9,600 in composite. It takes about 24 decking boards at 16 ft, 13 joists, 3 footings and 36 linear feet of railing.

A 10x16 deck is 160 square feet. In pressure-treated pine, expect roughly $2,816 – $4,400 installed. Cedar runs about $4,096 – $6,400 and composite about $6,144 – $9,600. Building it yourself typically removes 40 to 55 percent of those figures, because labour is around half of a finished deck price.
Laying boards across the 10 ft direction, you need 22 rows — that is 352 linear feet of decking, or about 24 boards at 16 ft with a waste allowance. A 16 ft board crosses the deck in one piece, so there are no butt joints.
About 3, one under each post, with posts at no more than 8 feet along the beam. That is roughly 0.37 cubic yards of concrete for 12 inch tubes poured 42 inches below grade — around 17 eighty-pound bags. Your own frost depth sets the real number and is not negotiable.
