W12×53 vs W14×53

A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.

W12×53 and W14×53 both weigh 53 lb per foot, so the choice comes down to depth and stiffness rather than weight.

W14×53 is the deeper section at a nominal 14 in., versus 12 in.

W14×53 has the greater bending strength: section modulus Sx of 77.8 in³ versus 70.6, about 10% more.
