How large is a typical travel coffee mug?

Travel coffee mugs come in a variety of sizes, but a typical size holds around 12 to 16 ounces (350 to 475 milliliters) of liquid. This is usually enough for a single serving of coffee, tea, or other hot beverage. Some travel mugs may be larger, holding up to 24 ounces (700 milliliters), while others may be smaller, holding only 8 ounces (235 milliliters). The size of a travel mug will depend on the individual's needs and preferences.
