Vanliga Frågor

Why 16 in or 24 in on-center spacing?
These are the most common stud spacings in residential framing — 16 in is typical for standard loads, while 24 in "advanced framing" spacing uses less lumber under lighter loads.
Why do openings add 3 studs each?
Door and window openings typically need a king stud, a jack (trimmer) stud on each side, and framing above — 3 extra studs per opening is a common rule-of-thumb allowance.
