Short answer: one US fluid ounce is 29.5735 ml, so an 8 oz cup is about 237 ml, a 12 oz cup about 355 ml and a 16 oz cup about 473 ml. A1 Traders lists white paper coffee cups in single and double wall, kraft double wall coffee cups, clear juice glasses with dome lids or flat lids, hard plastic glasses and coffee cup lids. The tables below show every listed size with its standard conversion.
Cup sizes are nominal: a cup sold as 8 oz by one brand can hold a little more or less than one from another brand, and the amount you actually serve is less than the brim-full volume. Use the conversions as a guide and check the photo with measurements on each product page.

Choosing cup sizes and matching lids
- Choose by drink and price point: the smaller sizes suit tea and short coffees, the middle sizes a regular coffee, and the large sizes iced drinks, juices and shakes. Many cafés stock two or three sizes rather than every size.
- Double wall for hot drinks. A double wall cup is generally more comfortable to hold with a hot drink than a single wall cup, which some customers hold with a sleeve or a second cup.
- Match lids by rim, not by ounces. A lid fits the cup's rim diameter, and two cups with the same ounce size can have different rims. The coffee cup lid listings do not state which cups they fit, so ask us on WhatsApp to confirm before you order lids and cups together.
- The juice glasses with dome lid are listed with their neck size (92 mm and 98 mm) in the name. Keep glasses and lids of the same neck size together.
- Clear plastic glasses are generally used for cold drinks; use paper cups for hot drinks. For straws and stirrers see paper and plastic straws.
- For takeaway, the bleach card and kraft categories list coffee cup carriers for 1 or 4 cups.
