Quick answer
Choose the LUX Tumbler 400ml if you want a roomy, oven-safe glass for generous drinks or small baking; choose the 240ml if you prefer a compact, lightweight tumbler for everyday coffee or tea.
Capacity and dimensions: how they change your daily use
The LUX Tumbler 400ml stands 120mm tall with a 85mm diameter, making it a substantial glass that suits larger servings like iced coffee, smoothies, or even small desserts. The 240ml version is shorter at 70mm and slightly wider at 88mm, giving it a low, stable profile that fits neatly under a coffee machine or in a compact kitchen shelf.
Because the 240ml is about 120g lighter, it feels noticeably easier to handle when you're moving around. The 400ml, while heavier, offers more room for creative drinks and food presentation.
Heat and oven safety: a key difference
Both tumblers share the same heat tolerance: they withstand a temperature difference of 120°C and are safe for microwave, dishwasher, and oven use up to about 200°C in a home oven. This makes both versatile for hot drinks and reheating.
However, the larger 400ml capacity is more practical for oven use—think baking small custards or individual gratins. The 240ml is better for quick reheating of a single serving or using as a ramekin, but its smaller size limits what you can prepare.
Always use oven mitts after heating, place on a mat or coaster to avoid table marks, and never freeze food in these glasses because expansion can cause breakage.
Trade-offs at a glance
- Capacity: 400ml holds nearly double the volume of the 240ml, so you can enjoy larger beverages or use it for oven-cooked single portions. The 240ml is perfect for standard coffee or tea servings. Think about your typical drink size: if you often fill a 300ml mug, the 240ml may feel too small.
- Weight and handling: The 400ml is about 120g heavier, which gives a more substantial feel but can be tiring to hold for long periods. The 240ml is lighter and easier to carry around the house or office. If you plan to use the glass while moving, the 240ml is more comfortable.
- Oven versatility: Both are oven-safe up to about 200°C, but the 400ml's larger capacity makes it more practical for baking small dishes. The 240ml works for reheating small portions or as a ramekin. Choose the 400ml if you want a glass that doubles as a baking dish.
