Behr lists its Barn & Fence Paint at 200 to 500 sq ft per gallon. Rough or weathered boards sit at the low end.

How the gallons are worked out

Area = length × height × sides. Gallons = area ÷ coverage for the first coat + area ÷ coverage for each extra coat.

Example: a 150 ft fence, 6 ft tall, one side, is 900 ft². At 200 ft² per gallon for the first coat and 200 for the second you need 9.0 gallons, so buy 9.
