W10×26 vs W12×26
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×26 and W12×26 both weigh 26 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W12×26 is the deeper section at a nominal 12 in., versus 10 in.
W12×26 has the greater bending strength: section modulus Sx of 33.4 in³ versus 27.9, about 20% more.
