W5×16 vs W5×19
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W5×19 is the heavier section at 19 lb per foot, versus 16 for W5×16 (3 lb/ft more).
Both are nominally 5 in. deep.
W5×19 has the greater bending strength: section modulus Sx of 10.2 in³ versus 8.55, about 19% more.
