I. Capacity Standard System and Conversion Relationships
1.1 Imperial and Metric Unit Conversion
Paper cup capacity usually uses the imperial ounce as the main unit of measurement, while also indicating the corresponding metric milliliter capacity. In international standards, 1 US fluid ounce equals 29.57353 milliliters, and 1 imperial fluid ounce equals 28.41306 milliliters. To standardize, the paper cup industry usually uses 30 milliliters to approximate the capacity of 1 ounce.
In practical applications, there are subtle differences in the use of ounces in different regions. Some data from the Chinese market shows that 1 ounce is approximately equal to 28.34 milliliters, which is closer to the imperial standard. This small difference in conversion does not significantly affect daily use, but it needs to be considered when precise measurement is required.

IV. Standardization of Capacity Specifications
4.1 International Standard System
In the international standard system, paper cup capacity specifications mainly follow ISO (International Organization for Standardization) standards. According to relevant information, ISO 7781 is the international standard for paper cup dimensions, specifying parameters such as capacity, diameter, and height.
The main characteristics of international standard paper coffee cups include:
The main characteristics of international standard paper coffee cups include:
- Standard capacity: 12 ounces (355 milliliters) is the main specification for ISO standard insulated paper cups
- Cup mouth diameter: Average of 90 millimeters
- Cup bottom diameter: Usually between 60-65 millimeters
- Height: Average of 120 millimeters
- Cup wall thickness: Between 0.25-0.35 millimeters
The global standard size range is from 120 milliliters (4 ounces) to 600 milliliters (20 ounces), which basically covers all daily use needs.
4.2 Chinese National Standards
China has established a strict national standard system for paper coffee cups, mainly including:
GB/T 27590-2022 "paper coffee cups" is the current national standard, issued by the State Administration for Market Regulation and the Standardization Administration of China on July 11, 2022, and implemented on February 1, 2023, replacing the original GB/T 27590-2011 standard. This standard is under the jurisdiction of the National Technical Committee for Standardization of Food Contact Materials and Products (TC397).
The national standard clearly specifies the capacity deviation of paper coffee cups, requiring that the deviation between the actual capacity and the marked capacity must meet the standard requirements. The standard also specifies the physical performance requirements of paper coffee cups, including indicators such as leakage performance and cup body stiffness. For example, cold drink cups need to hold water at 23°C±1°C, and hot drink cups need to hold water at 90°C±5°C, and are checked for leakage after standing for 30 minutes. 4.3 Industry Standards and Enterprise Standards
In addition to international and national standards, the paper cup industry also has various industry and enterprise standards:
Industry standards: For example, QB 2294-2006 "paper cups for hot beverages" and other light industry standards, although superseded by national standards, still have some technical specifications that are of reference value.
Enterprise standards: Major paper cup manufacturers have developed their own product specification systems based on market demand. For example, standards in the Japanese market include 5 ounces (150 ml), 7 ounces (205 ml), 9 ounces (275 ml), 12 ounces (355 ml), 14 ounces (420 ml), etc.

4.4 Capacity Specification Naming Conventions
There are significant differences in the naming of paper cup capacities across different regions and brands, reflecting differences in cultural background and usage habits:
The naming convention in the Chinese market is relatively straightforward, usually divided by capacity size:
The naming convention in the Chinese market is relatively straightforward, usually divided by capacity size:
- Small cup: 6.5 ounces (180 ml)
- Medium cup: 9 ounces (220 ml)
- Large cup: 12 ounces (340 ml)
However, the naming system is different in beverage shops and coffee shops:
- Small cup: 12 ounces
- Medium cup: 16 ounces
- Large cup: 20 ounces
Starbucks' naming system is the most unique, using Italian names:
- Short: 8 ounces (236 ml) - usually not listed on the menu
- Tall: 12 ounces (355 ml)
- Grande: 16 ounces (473 ml)
- Venti: 20 ounces (hot drinks) / 24 ounces (cold drinks) (591/710 ml)
- Trenta: 30 ounces (887 ml) - cold drinks only
The characteristic of this naming system is that "Tall" is actually a medium size, not literally a "large cup." This naming method stems from Starbucks' philosophy of providing more choices to consumers. The internationally recognized naming system is relatively simple:
- Small: 6-12 ounces
- Medium: 12-16 ounces
- Large: 16-20 ounces
- Extra Large: 20 ounces and above
4.5 Special Specifications and Non-Standard Capacities
In addition to the standard specifications mentioned above, many special specifications of paper cups for hot beverages exist on the market:
Non-integer ounce specifications: such as 7.5 ounces (220 ml), 8.6 ounces (240 ml), 14.5 ounces, etc. These specifications are usually customized according to specific needs.
European specifications: For example, an 8-ounce European paper cup has a capacity of 270 ml and dimensions of 81×51×94 mm, which is different from the standard 8 ounces (237 ml).
Special purpose specifications: such as 13A, 13B ounces (both 360 ml), 14B ounces (400 ml), etc. These specifications are mainly used for specific brands or regions.
