To determine the number of floor joists for a 12 by 21-foot deck, you typically space the joists 16 inches apart on center. The total length of the deck is 21 feet, which equals 252 inches. Dividing this by the 16-inch spacing gives you approximately 15.75, so you'll need 16 joists across the 12-foot width, plus one additional joist for the edge, resulting in a total of 17 joists.

How many 2x8 floor joists will you need for a 12x16 floor?
To determine the number of 2x8 floor joists needed for a 12x16 floor, first calculate the area of the floor, which is 192 square feet (12 feet x 16 feet). Assuming the joists are spaced 16 inches apart on center, you will need about 12 joists running the 16-foot length (16 feet = 192 inches; 192 inches ÷ 16 inches = 12). Therefore, you will need approximately 12 joists to support the floor.

How many 2x4's will you need to build a 10ft by 10ft deck?
It's unlikely you would use many 2X4s on a deck. The joists (under the decking) are usually 2X6 or larger. The larger the joist, the fewer you need, because you can space them further apart. The decking is made of 1X6s nailed or screwed to the top of the joists, and running perpendicular to the joists or at an angle to the joists. The amount of decking you need depends on whether you intend to make a pattern (herringbone) or a typical deck. The railing might include 2X4s as the top rail, but the support posts are usually 4X4s, and in between those, you usually use small stock to add the decorative posts/slats.
