Understanding Chips Portions

Essential party snack. Plan for about 2 oz per person for snacking. When planning for a group, the key is knowing that the average adult consumes 2 servings of chips.

Factors That Affect Portion Size

  • Time of day: Lunch portions are typically 20% smaller than dinner portions.
  • Other foods: When serving multiple dishes, reduce chips by 25-30%.
  • Guest demographics: Teenagers eat more, seniors and young children eat less.
  • Event type: Casual events see more eating; formal events see less.
  • Duration: Longer events need more food as people graze over time.

The Formula

To calculate chips for any group:

Number of Guests ร— 2 = Total Servings

Pro Tips for Chip Servings

  • One large party-size bag (16oz) serves 8 people
  • Offer 2-3 dips alongside
  • Pour into bowls - don't serve from the bag
  • Keep opened bags clipped for freshness
  • Include veggie chips for variety

Common Mistakes to Avoid

  • Don't assume everyone eats the same amountโ€”always add a 10-15% buffer
  • Don't forget about dietary restrictionsโ€”have alternatives ready
  • Don't order last minute for large groupsโ€”plan ahead for best selection
  • Don't underestimate hungry crowdsโ€”when in doubt, order more

How many oz does one person eat?

On average, one person eats 2 oz of chips. This can vary based on appetite, whether it's a main dish or appetizer, and what other foods are being served.

How do I calculate chips for a group?

Multiply the number of guests by 2 (the average per person). For example, for 20 people: 20 ร— 2 = 40 oz.

Should I order extra chips?

Yes, it's smart to order 10-15% extra to account for big appetites, unexpected guests, or leftovers. It's better to have a little too much than run out during your event.

Do kids eat less chips than adults?
