Every cell is the same arithmetic the sheet does: one stud on each layout line from the left end, plus the end stud, rounded up. A 12 ft wall at 16 in on center is 144 over 16, nine bays, ten studs. What the table cannot show is the part that changes the order — corners, walls butting in, and the kings, jacks and cripples each door and window brings with it. That is what sheet S-202 counts, against 2 documents: APA’s description of conventional and advanced framing, and the code section that sends stud size, height and spacing to a table this site links rather than reprints. No precut length, no waste default and no price are built in: nothing we opened publishes one.
