W12×210 vs W36×210
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×210 and W36×210 both weigh 210 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W36×210 is the deeper section at a nominal 36 in., versus 12 in.
W36×210 has the greater bending strength: section modulus Sx of 719 in³ versus 292, about 146% more.
