Quick Answer
For 100 people, you need 200 oz. This provides about 200 servings, assuming 2 servings per person.
Estimated cost: $50 - $100
How We Calculate
We use the industry-standard formula for chips calculations:
-
Each person eats approximately 2 oz
-
Formula: 100 people × 2 servings ÷ 1 = 200 oz

Tips for Ordering 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
Planning Guide: Chip Servings for Your Event
The individual bag versus party-size bag economics heavily favor party-size bags when hosting groups, but presentation matters. A party-size bag (typically 13-16 oz) costs about 40% less per ounce than individual 1-ounce bags, and you avoid the waste of 30+ individual wrappers. However, individual bags offer portion control that prevents the bottomless-chip-bowl syndrome where people mindlessly eat more than they intended. The compromise solution is buying party-size bags but portioning them into medium bowls scattered around the party space rather than one giant bowl. This creates multiple snacking stations, reduces crowding, and surprisingly makes chips last longer because people are more conscious of portions when serving themselves from a smaller bowl. For a 40-person party, plan on 5-6 party-size bags distributed across 8-10 serving bowls placed strategically near seating areas and standing zones.
Chip variety strategy prevents the situation where plain chips remain while flavored chips vanish in 30 minutes. The safe distribution for mixed crowds is 50% plain/lightly salted chips, 30% crowd-pleasing flavors like BBQ or sour cream & onion, and 20% bold flavors like jalapeño or salt & vinegar. This ratio ensures you don't run out of the universal options while still offering variety for adventurous snackers. Corn chips (like Fritos) versus potato chips is worth considering - corn chips are sturdier for dipping and pair better with queso and salsa, while potato chips work better as standalone snacks. For health-conscious crowds, include one option of baked chips or veggie chips, but don't expect them to be as popular as regular chips - people indulge at parties. Kettle-cooked chips are thicker and crunchier, making them more satisfying with dips, but they're also 20-30% more expensive.
Chip freshness preservation during multi-hour events requires vigilance because stale chips ruin the snacking experience. Never pour all your chips out at once - atmospheric humidity starts degrading crispness immediately. Instead, keep backup bags sealed and refill bowls as needed. In humid climates or outdoor settings, chips can go from crispy to chewy in under an hour. The professional trick is using bag clips to reseal opened bags and storing them in a dry location between refills. For outdoor events, position chip bowls under canopies or indoors rather than in direct sunlight or near water features where humidity concentrates. If chips do go slightly stale, you can revive them by spreading on a sheet pan and warming in a 350°F oven for 3-5 minutes, then cooling completely. This re-crisping technique works surprisingly well for chips that have lost their crunch but aren't otherwise spoiled.
