W10×68 vs W14×68
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×68 and W14×68 both weigh 68 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W14×68 is the deeper section at a nominal 14 in., versus 10 in.
W14×68 has the greater bending strength: section modulus Sx of 103 in³ versus 75.7, about 36% more.
