W10×22 vs W12×22
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×22 and W12×22 both weigh 22 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W12×22 is the deeper section at a nominal 12 in., versus 10 in.
W12×22 has the greater bending strength: section modulus Sx of 25.4 in³ versus 23.2, about 9% more.
