Below is a table giving the minimum size floor joists needed for 16â³ and 24â³ on center (o.c.) spacing when using #2 lumber with 10 pounds per square foot of dead load and 40 pounds of live load. You can always use bigger lumber, closer spacing, or a smaller span; just donât go smaller, further apart, or a longer span.
Estimating Wood and Screws for the Lower Frame. If the width parallel to the joists is W feet, the length perpendicular to the joists is L feet, and the spacing between the joists is J inches, then the length of board needed for the frame is. 12LW/J + W + 2L (feet). The number 12 is for converting joist inches to feet.Assuming that you put two screws per joint, the number of screws needed for the frame is at least. 412L/J + 4. You may need more if you double the joists. Always add about 3%-5% extra for wood and screws so you don't run short of building materials.he number 12 is for converting joist inches to feet.
