W18×192 vs W24×192
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W18×192 and W24×192 both weigh 192 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W24×192 is the deeper section at a nominal 24 in., versus 18 in.
W24×192 has the greater bending strength: section modulus Sx of 491 in³ versus 380, about 29% more.
