W12×16 vs W12×19
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×19 is the heavier section at 19 lb per foot, versus 16 for W12×16 (3 lb/ft more).
Both are nominally 12 in. deep.
W12×19 has the greater bending strength: section modulus Sx of 21.3 in³ versus 17.1, about 25% more.
