Number of Spaces
The total length is split into this many equal spaces. To place N evenly-spaced objects between two ends, use N + 1 spaces — e.g. 2 lights on a 24 ft wall = 3 spaces, giving marks at 0, 8, 16, and 24 ft.

Marks are laid out at this fixed interval from the start. The end of the run is always added as a final mark, even if the last interval is short. Common framing spacings are 16, 19 3/16 (19.2), and 24 inches on-center.
