Plan on 1 1/2 potatoes per a person. This depends on how close you want to cut it. If it is important that you don't run out go to 2 potatoes a person. If some of the people are younger or older and can't eat as much this should be taken into account and provide about a half a potato. This estimation is based on a regular sized russet or bakers potato.
Well you will need close to 70 if you wish to feed 70 people. But if you boil then MASH then you will need less. Honestly it depends on how hungry your guests are or how much they like potatoes.
As a guide allow 4 ounces of potato salad per person.
4oz x 70 equals 180oz, that's 17.5 pounds of potato salad.
Some folk may take a little more, some folk won't take any as they might not like potato salad.
Therefore 17.5 pounds should be enough for 70 people.
The normal serving is estimated to be 4 ounces. To feed 70 people you would need just over 17 pounds of potato salad. The quantity may vary depending on what else is served.
good rule of thumb is 2 potatoes per person
To make that kind of judgement we really need to know what else they are having. If only potato salad, then I would use 35 pounds.
Thirty pounds per hundred.
I would serve about 18 pounds .
That is 87.5 pounds
To serve 300 people, you will need about 9.375 gallons of potato salad. This is based on one gallon being 16 cups, so, if you figure 1/2 cup per serving, one gallon should serve 32 people.
Since 25 pounds feeds 100, you'll need 106 1/4 pounds of potato salad.
25 pounds of potatos shoud be about right.
2.5 pounds of potato
5 lbs would make enough for about 20 people. Glad I could help.
The normal serving of potato salad should be around 4 ounces. 1 pound would feed 4 people, so you would need 33 and 3/4 pounds to feed 135 people.
I would serve 4 oz per person. So 5 pounds for 20 people.
potatos
I would get 20 pounds.
Four ounces is considered the normal serving. For 150 to 200 people you will need 40 to 50 pounds. If they are hungry you may want to go more than that!
A good rule of thumb with any potato dish is 1 potato per person. This always works because some will eat less.
