In architecture and engineering, a joist is one of the horizontal supporting members that run between foundations, walls, or beams to support a ceiling or floor. Typically, a joist has the cross section of a plank. Joists are often supported by beams laid out in repetitive patterns.
Best Answer: Ceiling joists are usually part of the roof truss system and would typically be 24 on center. If the home is not trussed, but is built with a stick framed roof, ceiling joists could be 16, 24 or less commonly 19.2 (19 3/8) on center. Depends upon the span and loading requirements. Wall studs will be either 16 or 24 on center.
