Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Regulatory standards & verification citations

  • CFS stud count = ceil(wall length ÷ spacing) + 1 — the standard layout method, counting both end studs plus intermediate studs at 16 in or 24 in o.c. per SSMA/IBC/ASCE, identical in method to wood stud framing

Frequently asked questions

Why add 1 to the divided result?
Dividing wall length by spacing gives the number of spaces between studs; adding 1 accounts for the stud that starts the run, so the count covers both end studs plus every intermediate stud.
Should I use 16 in or 24 in on-center spacing?
16 in o.c. is the most common CFS wall spacing. 24 in o.c. can reduce stud count and cost, but only where the stud size, gauge, and applied loading (per AISI S100 and the wall's design) support the wider spacing — confirm against your project's structural requirements.
Does this account for extra studs at openings, corners, or T-intersections?
No — this gives the base field stud count for a straight run at uniform spacing only. King/jack studs at door and window openings, corner framing, and backing at T-intersections need to be added on top of this count.
