I would make 125 pounds of salad.
For 25 people, 10-11 lbs. of salad should be plenty. However, just to be sure, 12 lbs. would be more than plenty.
1 Gallon of potato salad feeds about 30 people, so 3.33 Gallons.
You should plan for about 1/2 cup per person. That make 250 cups which would be just under 16 gallons of potato salad.
