Choosing coffee cups and coffee glasses: sizes, materials and suitable sets compared

Whether it is your morning coffee at home, an espresso after a meal or a coffee break at the office: coffee cups and coffee glasses can differ considerably in capacity, material, heat retention and care requirements. Choosing carefully helps prevent an attractive product from becoming impractical in everyday use.

Common pitfalls when buying coffee cups and coffee glasses

1. The stated capacity is misjudged

A cup with a capacity of 200 ml cannot automatically be filled with 200 ml of coffee right up to the rim. Manufacturers’ specifications often refer to the maximum volume. For practical use, you should leave some space for milk, milk foam or safe carrying.

As a guide:

  • Small coffee cups with 60 to 100 ml are suitable for espresso, ristretto and short coffee specialities.
  • Coffee cups with 200 ml are ideal for filter coffee, Americano or smaller portions of milky coffee.
  • Cups and glasses with 270 to 300 ml offer more room for cappuccino, tea or larger hot drinks.

2. “Heat-resistant” is taken to mean suitable for every use

Glass may be suitable for hot drinks, but it is not automatically ovenproof or protected against extreme temperature changes. With borosilicate glass cups in particular, you should follow the specific care and safety instructions. Moving directly from very cold to boiling-hot conditions can be problematic even for temperature-resistant glass.

With double-walled models, the benefit lies in the construction: the layer of air between the glass walls reduces heat exchange. As a result, the outer glass can feel more comfortable to hold when filled with hot drinks. Actual use should nevertheless follow the manufacturer’s specifications.

3. Dishwasher and microwave suitability are not checked

The product information should explicitly state that the cups are dishwasher-safe. With printed, glazed or very delicate surfaces, aggressive detergents and high temperatures can affect their appearance over time.

“Microwave-safe” is also not a general feature of every ceramic or glass cup. Metal components, metallic decoration and certain double-walled constructions must be ruled out. Before buying, it is therefore worth checking the care instructions rather than relying solely on the product image.

The most important selection criteria at a glance

Capacity to suit the coffee speciality

The quantity of the drink should match the shape of the cup. For espresso, a small espresso cup set of around 7 to 10 cl is recommended. Cappuccino requires more capacity to accommodate the espresso, milk and milk foam. For tea or longer coffee specialities, tea cup sets or larger drinking vessels with a capacity of 200 ml or more are more practical.

Material: ceramic or glass?

Ceramic coffee cups retain heat comparatively well and are available in a wide range of shapes and designs. A thicker wall can be comfortable for everyday use, but it often increases the weight.

Borosilicate glass cups make the colour and crema clearly visible. Double-walled coffee glasses also create an insulating space between the walls. However, glass remains vulnerable to breakage if it falls onto a hard surface or is knocked against something. Before each use, check for visible cracks or chips.

Cleaning, storage and safety

Before buying, check the following:

  • Is the vessel explicitly dishwasher-safe?
  • Is it marked as microwave-safe?
  • Can it be stacked?
  • Are the handles, glass walls and base sufficiently sturdy for the intended use?
  • Is a saucer, stand or storage solution included?

Double-walled glasses are not always designed to be stacked. This can be important in a small kitchen cupboard or for larger households.

FAQ about coffee cups and coffee glasses

What size is suitable for regular coffee?

For filter coffee and smaller portions of milky coffee, 200 ml is often sufficient. If you serve larger drinks or plenty of milk foam, it is better to choose 270 to 300 ml. The usable capacity is usually below the maximum volume up to the rim.

Are double-walled coffee glasses dishwasher-safe?

This depends on the individual model. Some double-walled coffee glasses made from borosilicate glass are explicitly described as dishwasher-safe. You should still follow the manufacturer’s instructions, as aggressive detergents and high temperatures can affect transparency over time.

Which is more durable: ceramic coffee cups or glass?

Both materials can provide long-lasting use when handled correctly. Ceramic is often less susceptible to minor knocks in everyday use, but it can chip at the edges. Glass makes drinks clearly visible, but can break if dropped or subjected to hard impacts. Material thickness, care and safe storage are key to product longevity.
