IMO It's trial and error depending on your deer densities and the ag / land around you. I can plant 1-2 acres and have beans in the fall but I have quite a bit of ag around me. But that's also changing as our numbers have increased in the last two years.. Others (like jsasker above) have to plant larger fields to keep up.
@Bill I'd be curious to hear your experiences here as well.
I would never plant less then 4 acre of beans if like trooper says I wasn’t surrounded by ag beans on the neighbors place. My farm is cut by a road and while deer cross roads many tend to bed and feed on one side during daylight. I plant a minimum of 4 acres on each side. Not necessarily in the same field, some plots are only 1/2 acre. But they are a short walk to another field for the deer.
Last year I only planted about 3 total acres per side and my neighbor switched to corn. The deer just decimated my beans. This year I upped my beans and the neighbors planted ag beans so I’m in good shape.
One other consideration on a small bean plot is location. In my experience hidey hole plots that are removed from a road, prying eyes or disturbance of a neighbor get hammered. If there is 100 acres of beans near a road and 2 acres of beans in a remote quiet place the deer will choose the 2 acres.
Here is a hidey hole bean plot in August. The beans are behind the rubbing post and about 4 inches tall. I broadcast brassicas into them in July and the deer hammered them as soon as they sprouted also. I broadcast rye into them in Sept and it was kept mowed to the ground also. 400 yards up the hill I had a 4 acre plot that was 2 foot high.
Location matters.
Same field in July.
