Paper cups are named in ounces (oz), but when you order, the real question is how much the cup holds. This guide puts each size’s volume, dimensions, typical use and matching lid in one place.
Why oz isn’t exactly ml
One fluid ounce is about 29.6 ml. On cups, though, oz is a trade size: cups sold as “8 oz” can differ slightly in volume from one maker to another. When comparing, look at the volume and rim diameter rather than the oz name.
The cc values in the table below are catalogue volumes. The drink actually served usually sits a little below that, since space is left at the top.
Size table
| Size | Volume | Top Ø | Height | Typical use | Lid |
|---|---|---|---|---|---|
| 4 oz | 100 cc | 62 mm | 60 mm | Espresso, tasting | Ø62 |
| 7 oz | 150 cc | 70 mm | 80 mm | Vending, tea | Ø70 |
| 7.5 oz | 180 cc | 70 mm | 90 mm | Vending | Ø70 |
| 8 oz | 250 cc | 80 mm | 92 mm | Standard coffee and tea | Ø80 |
| 12 oz | 300 cc | 80 mm | 117 mm | Latte, takeaway | Ø80 |
| 14 oz | 350 cc | 90 mm | 110 mm | Large | Ø90 |
| 16 oz | 450 cc | 90 mm | 132 mm | Large, cold drinks | Ø90 |
Which size to choose
- 4 oz is enough for espresso and tastings.
- Vending machines use 7 or 7.5 oz, to suit the machine’s cup holder.
- 8 oz is the most common size for standard coffee and tea.
- 12 oz suits lattes and takeaway drinks.
- 14–16 oz works for large and cold drinks.
Lid fit
Lids are chosen by rim diameter, not by the cup’s name. The Ø62 lid fits 4 oz, Ø70 fits 7 and 7.5 oz, Ø80 fits 8 and 12 oz, and Ø90 fits 14, 16, 20 and 22 oz. The 3 and 5 oz cups have no lid. Sizes that share a rim share a lid, so ordering 8 and 12 oz together needs just one lid type.
