W14×132 vs W21×132
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×132 and W21×132 both weigh 132 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W21×132 is the deeper section at a nominal 21 in., versus 14 in.
W21×132 has the greater bending strength: section modulus Sx of 295 in³ versus 209, about 41% more.
