PET Cup Sizes and Lid Fit Chart
PET cup lids are sized by the cup rim in millimeters, not by ounces. In our line, 9oz cups take the 92mm lid; 12oz, 16oz, 20oz and 24oz cups take the 98mm lid; 32oz cups take the 107mm lid. Any 98mm lid (flat, flat with straw hole, dome or slip-through) fits every 98mm cup, so one lid stock covers four cup sizes.
- 92mm 9oz
- 98mm 12oz to 24oz
- 107mm 32oz
- 1,000 cups per case

PET cup lid types
Flat lids with a straw hole are the default for iced coffee, tea and soft drinks. Dome lids leave room for whipped cream and blended drinks. Slip-through lids let a straw pass without a separate hole.
| Lid type | Fits rim | Case pack | Cases / pallet |
|---|---|---|---|
| Flat Lid | 107mm | 500/Case | 45 |
| Dome Lid | 98mm | 1000/Case | 45 |
| Flat Lid With Hole | 98mm | 1000/Case | 50 |
| Slip Thru Lid | 98mm | 1000/Case | 45 |
How to choose a cup size
- 9oz: kids’ drinks, samples, water cups and smaller cold desserts.
- 12oz to 16oz: the standard small and medium for iced coffee, tea and soft drinks.
- 20oz to 24oz: large iced drinks, smoothies and boba.
- 32oz: extra-large drinks and party-size servings; it takes its own 107mm lid.
Standardizing on the 98mm rim (12oz to 24oz) is the easiest way to cut lid SKUs: four cup sizes, one lid size.
