How many pounds of potato salad for 25 people?

A good rule of thumb is to estimate 1/2 to 3/4 pound of potato salad per person.

So, for 25 people, you'd need:

* Minimum: 12.5 pounds (25 x 0.5)

* Average: 18.75 pounds (25 x 0.75)

Consider these factors:

* Appetites: Are your guests big eaters? You might want to go for the higher end of the estimate.

* Other foods: Is there a lot of other food being served? You might be able to get away with a bit less potato salad.

* Leftovers: Do you want to have leftovers? You might want to make a bit extra.

Ultimately, it's best to err on the side of making too much rather than too little. You can always freeze leftover potato salad for later!
