Why Coffee Shop Iced Sizes Differ from Boba
In the North American coffee market, iced beverages are dominated by the 98mm caliber PET cup. Unlike the 95mm standard common in Asian boba shops, the 98mm width provides a wider profile that accommodates larger amounts of ice and fits universal US cup holders. Understanding how giants like Starbucks and Dunkin size their drinks is key to choosing your own inventory.
Starbucks Iced Cup Sizes (oz to ml)
Starbucks uses unique names for its volumes. If you want to offer a "Trenta" equivalent, you need our 107mm jumbo series.
| Name | oz | ml | Sourcing Equivalent |
|---|---|---|---|
| Tall | 12 oz | 355 ml | 98-12oz (98mm) |
| Grande | 16 oz | 473 ml | 98-16oz (98mm) |
| Venti | 24 oz | 709 ml | 98-24oz (98mm) |
| Trenta | 31 oz | 916 ml | 107-10701 (32oz) |
Dunkin Iced Cup Sizes (oz to ml)
Dunkin sizes are typically larger than Starbucks at the "Small" and "Medium" tiers, favoring high-volume iced coffee drinkers.
| Name | oz | ml | Sourcing Equivalent |
|---|---|---|---|
| Small | 16 oz | 473 ml | 98-16oz (98mm) |
| Medium | 24 oz | 709 ml | 98-24oz (98mm) |
| Large | 32 oz | 946 ml | 107-10701 (32oz) |
Choosing the Right Caliber for Coffee
If you are targeting the US or European coffee market, we recommend standardizing on the 98mm PET caliber. This allows you to use one lid size across 12oz, 16oz, and 24oz cups, significantly reducing storage needs. For premium "Trenta" or 32oz sharing sizes, the 107mm caliber (Model 107-10701) provides the necessary structural rigidity for heavy, ice-filled drinks.
