How many milliliters are in a shot glass?
Different countries and regions have different methods of measuring spirits, and a standard shot glass typically ranges in size from 20ml to 60ml. For example, 25ml or 35ml is common in the UK, while 30ml or 50ml is more common in Spanish bars. Understanding these differences not only helps consumers mix or drink drinks correctly, but also helps bar owners, catering buyers, and glass importers choose products that better meet local market demands.
This article will introduce the shot glass capacity standards of major countries around the world, the conversion between milliliters and ounces, and how to choose the appropriate shot glass for different applications.

Standard Shot Glass
Shot Glass is a type of glass drinking vessel specifically designed for holding spirits (such as vodka, tequila, whiskey, rum, etc.). It is commonly used for a single serving (Single Shot) or for precise measurement of liquid during cocktail mixing. However, contrary to what most people might think, there is no such thing as a globally unified “standard shot”.
Below are the common capacities for several major countries and regions:
| Country | Common capacity |
| Spain | 30ml / 50ml |
| Britain | 25ml / 35ml |
| Germany | 20ml / 40ml |
| France | 25ml |
| Italy | 40ml |
| United States | 44ml(1.5 oz) |
| Australia | 30ml |
This shows that the same shot can vary by more than double between different countries.
Why do Shot Glass Capacities Differ Between Countries?
The capacities of shot glass are primarily affected by the following factors.
Alcohol regulations
Some European countries have specific regulations regarding the measurement of spirits sold in bars. For instance, in the UK, it is stipulated that bars can only use 25ml or 35ml as the capacity of a single serving of spirits, and as a result, the specifications of wine glasses have also been standardized.
Drinking Culture
The way of drinking varies from country to country. For instance, in Spain and Italy, people prefer to enjoy strong alcohol in social settings, so 30ml and 50ml wine glasses are more common; while in some parts of Germany, they prefer smaller capacity Shots.

Metric and Imperial Measurement Systems
In the United States, ounces (oz) are still widely used as a unit for measuring alcoholic beverages, while in Europe, milliliters (ml) are the standard. This is one of the key reasons for the differences in product specifications across different markets.
How to Convert Milliliters (ml) to Ounces (oz)?
Since the metric system is often used in both Europe and America, it is very important to understand the conversion between milliliters and ounces.
| Milliliter (ml) | Ounce (oz) |
| 20ml | 0.68 oz |
| 25ml | 0.85 oz |
| 30ml | 1.01 oz |
| 35ml | 1.18 oz |
| 40ml | 1.35 oz |
| 50ml | 1.69 oz |
| 60ml | 2.03 oz |
If you plan to purchase Shot Glass, it is recommended to confirm whether the supplier also indicates both ml and oz as the capacity units. This will not only facilitate communication with customers or teams from different countries, but also prevent errors in specification selection due to different measurement units.
Common Types of Shot Glass
Although the capacities vary, Shot Glass comes in many different designs.
Common styles include:
- Classic straight-sided Shot Glass
- Thick-bottomed Shot Glass (Heavy Base)
- High-legged Shooter Glass
- Measuring Shot Glass with scale
- Colored glass Shot Glass
- Sanded Shot Glass
Different designs are suitable for bars, restaurants, brand gifts and the retail market, and can also meet the personalized needs of different brands.

How to Choose the Right Shot Glass for Your Business?
For the bar and catering industries, when choosing wine glasses, not only the capacity but also the usage scenario should be taken into consideration.
For example:
- Bars pay more attention to durability and uniform specifications;
- Hotels place greater emphasis on the design of the exterior;
- Whiskey brands usually customize promotional glasses with logos;
- Gift companies tend to choose special colors or customize the packaging.
Can the Capacity of the Shot Glass be Customized?
The answer is yes. At present, most professional glass manufacturers offer the option to customize Shot Glasses of various capacities to meet the needs of different countries and brands.
Common customization specifications include: 20ml
- 25ml

Summary

In the European market, the main capacities used are 25ml, 30ml, 40ml, and 50ml. However, the specific choice also depends on local regulations, drinking culture, and usage scenarios.
