Wall Stud Quantity Calculator
Estimate preliminary vertical studs for a straight run of wall before detailing corners, intersections and openings.
How this calculator works
Ceiling[wall length (ft) × 12 ÷ on-center spacing (in)] + 1, then add waste % and round up.
This is a simplified count for one straight wall. Additional studs for headers, king/jack studs, partitions, intersections, blocking, cripple studs and bracing require a full framing layout.
Use field-verified dimensions. This planning estimate does not substitute for a complete takeoff, structural design or local supplier quote.
