W14×61 vs W14×68
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×68 is the heavier section at 68 lb per foot, versus 61 for W14×61 (7 lb/ft more).
Both are nominally 14 in. deep.
W14×68 has the greater bending strength: section modulus Sx of 103 in³ versus 92.1, about 12% more.
