Metal stud walls are framed with vertical studs running between a top and bottom track, so ordering materials means figuring out two separate things: how many studs fit the wall at the required spacing, and how much track is needed to run along both the floor and ceiling. Stud count follows the same logic as wood framing — divide the wall length by the on-center spacing (converted to feet) and add one for the starting stud at the wall's beginning.

Track is needed on both the top and bottom of the wall, so total track footage is twice the wall length, which then gets divided by the length each track piece is sold in (commonly 10 ft) to get a shopping-list count, rounded up since track is not typically spliced mid-piece.
