However, by the time you get done stealing a few inches from each dimension, soon your 100-foot wide four-row free-stall barn becomes a 95-foot wide barn. That makes a big difference to your cows. The goal: A four-row free-stall barn should be 100 feet wide. Thatâs two 10-foot back alleys, two sets of head-to-head free-stalls at 16 feet apiece, two front alleys at a width of 14 feet apiece, and a center drive-through feed alley at 20 feet. Added up, you need a 100-foot wide barn.
