W14×211 vs W18×211
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×211 and W18×211 both weigh 211 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W18×211 is the deeper section at a nominal 18 in., versus 14 in.
W18×211 has the greater bending strength: section modulus Sx of 419 in³ versus 338, about 24% more.
