Joist span refers to the length of the joist from one end to the other, while joist spacing is the distance between each joist, which is typically measured from the center of one joist to the center of the next joist. This type of measurement is known as on-center-spacing.

The span and spacing of the deck joists can vary depending on the type of material used in the construction of the deck. For instance, metal joists can typically span several more feet than a standard wooden joist.
