W14×370 vs W24×370
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×370 and W24×370 both weigh 370 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W24×370 is the deeper section at a nominal 24 in., versus 14 in.
W24×370 has the greater bending strength: section modulus Sx of 957 in³ versus 607, about 58% more.
