Whether you are hosting a Dinner Party for 10 or a Graduation Party for 100…you need to know how much food to buy and prepare. Serving your guests is an important part of the party and you want it to go smoothly, not enough food is embarrassing, and too much food means leftovers for days.

How to Best Estimate Food for a Party

How to Best Estimate Food for a Party

Here are some basic guidelines that I found on About.com for individual serving sizes of various foods. Multiply these estimates by your number of guests and always round up your estimates, extra food is always best.

How to Estimate Portion Size Per Person

Hors D’oeuvres

  • 6 bites when preceding a meal.
  • 4 – 6 bites per hour when hors d’oeuvres are the meal.
  • The longer your party and the larger your guest list, the greater the number of selections you should offer.

The Main Meal

  • Poultry, meat, or fish – 6 ounces when you have one main dish, 8 ounces when you offer two or more main courses.
  • Rice, grains – 1.5 ounces as a side dish, 2 ounces in a main dish such as risotto.
  • Potatoes – 5 ounces
  • Vegetables – 4 ounces
  • Beans – 2 ounces as a side dish
  • Pasta – 2 ounces for a side dish, 3 ounces for a first course, 4 ounces for a main dish
  • Green Salad – 1-ounce undressed weight


  • 1 slice cake, tart, or pastry
  • 4 ounces creamy desserts such as pudding or mousse
  • 5 ounces of ice cream
  • When serving two of the above, reduce each by a little less than half.

Menu Planning Tips

  • Don’t repeat the main ingredient. For example, don’t serve a shrimp appetizer and shrimp as the main dish.
  • Consider the colors of the food that will be served together and make sure there is variety.
  • Offer both hot and cold foods on a buffet.
  • Mix textures such as a crisp potato galette served with a soft vegetable puree as side dishes.
  • So what about drinks? Should you serve soda in a can or bottle? Lemonade or Juice? And what about alcohol?
