How much weight can a 2×6 ceiling joist hold?

Fine Homebuilding notes that 2-inch by 6-inch garage joists will support a weight of up to 50 pounds per square foot. If you overload your garage’s ceiling joists, the ceiling may appear to sag from the strain.

How much weight will a ceiling joist hold?

50lb/sqftRegular garage ceiling joists of modern construction can generally support 50lb/sqft. If you have trusses or your joists are supporting more than just sheetrock or your garage is older this number could be significantly less. Remember to spread the load ACROSS your joists and not along them.

Beam bending strength is proportional to the width of the beam, but to the cube of the height.
