According to the Food Network, 1/3 to 1/2 pound of potatoes should be allocated per person when preparing mashed potatoes. When serving roasted potatoes, 2 1/2 pounds of potatoes should be allocated per person.
If you are a new grower, you may want to expect between 5 and 10 lbs for every pound you plant (1/2 to 1 pound per foot of row, or 10,000 to 20,000 lbs/acre). Potatoes can yield much higher than the numbers above, but we advise being cautious about your expectations.
