A set of drinking glasses may seem straightforward at first glance: choose the quantity, capacity and design, place your order and you’re done. In practice, unclear product information often leads to disappointing purchases. Some glasses are intended for cold drinks only, while others require hand washing or are not suitable for use in the microwave. The set size can also be misleading if the individual glasses are considerably smaller than expected.
This Joybuy Product Recommendation Officer’s guide explains which details really matter when choosing glass sets and which models are suitable for different uses.
The specifications 30 cl, 38 cl or 40 cl generally refer to the capacity when filled to the rim. For water, juice or soft drinks, you will usually leave a little space at the top. If you plan to serve large portions or use ice cubes, you should therefore avoid choosing a capacity that is too small.
For everyday use, water glasses and juice glasses are often around 25 to 40 cl. Smaller glasses, on the other hand, are better suited to espresso, aperitifs or spirits.
Standard soda-lime glass may be suitable for cold drinks, but it is not necessarily resistant to sudden temperature changes. Pouring hot water into a cold glass can cause thermal shock. One model explicitly states that it is not made from heat-resistant glass and that sudden temperature changes of more than 60 °C should be avoided.
For coffee, tea or hot chocolate, double-walled glasses or borosilicate glass are therefore a more suitable option, provided the manufacturer explicitly approves this use.
The care instructions should be followed when using dishwasher-safe drinking glasses. High temperatures, harsh detergents and contact with other tableware can eventually cause clouding, scratches or chips. Wooden lids, seals and specialist drinking straws often need to be cleaned separately.
For a household with several people, six glasses are practical, as there will be enough available when guests visit. A set of two may be sufficient for coffee drinks, a desk or a smaller household. For offices, cafés, restaurants and hotels, the option to purchase additional glasses, consistent shapes and easy cleaning are also important.
Pay attention to the actual number of glasses included. The quantity stated on the packaging or carton is not always the same as the sales unit.
When serving hot drinks, never rely solely on terms such as ‘insulated’ or ‘thermal glass’. The material, permitted temperature range and instructions regarding microwave or oven use are what really matter.
Short tumbler glasses are stable and can be stored in a space-saving way. Tall glasses are suitable for water, iced tea, cocktails, smoothies and layered drinks. Check the diameter, height and cupboard clearance before buying.
A smooth inner surface makes cleaning easier. Textured designs, wooden lids or glass straws may look appealing, but they require additional care. If glasses are damaged, cracked or chipped, stop using them immediately.
Why this product suits this profile: The set contains six glasses in different colours, each with a capacity of 30 cl. This makes them easy to tell apart in a busy family household or at a party.
The product details clearly state the quantity, material and capacity. The set is also specifically intended for cold drinks and not for hot liquids.
Six glasses, 30 cl per glass, in a compact format measuring 7,9 cm in diameter and 9,3 cm in height. Hand washing is recommended.
Why this product suits this profile: The double-walled design is intended to provide comfortable use with both warm and cold drinks. The set of six is ideal for households and hosts who prefer a coordinated look.
The insulation reduces direct contact between your hand and the surface containing the drink. However, you should still follow the manufacturer’s guidance on temperature changes and care.
Six double-walled glasses with a capacity of 0,4 l; suitable for different types of drinks according to the manufacturer’s specifications.
Why this product suits this profile: The tall 38 cl format is suitable for water, juice, iced tea, cocktails and soft drinks. The product description states that it is suitable for everyday use and social occasions.
The specifications distinguish between microwave suitability and heat resistance: the glass is approved for microwave use, but is not heat-resistant. Boiling water and sudden temperature changes should be avoided.
38 cl capacity, transparent soda-lime glass and dishwasher suitability according to the product details. Check for cracks or chips before use.
We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
For a household with several people, six glasses are a practical starting point. If you regularly have guests, or are buying for an office or hospitality setting, a larger quantity may be more suitable. For special drinks such as espresso or cold brew, sets of two are often sufficient.
Glasses of around 25 to 40 cl are versatile enough for water, juice and soft drinks. If you use ice cubes or serve large portions, choose a larger glass. However, capacity alone does not indicate the amount that will actually be poured.
That depends on the individual model. Some glasses are explicitly described as dishwasher-safe, while others should be washed by hand. Double-walled glasses, decorative finishes, wooden lids and specialist accessories often have different care requirements. The product description and manufacturer’s specifications should therefore be checked before purchase.
