Enamel Mug Sizes Guide: Diameters, Capacities and Popular Choices

Short answer: Enamel mugs are usually described by their diameter. The most popular sizes are 8, 9 and 10 cm, which hold roughly 300–500 ml (about 10–17 oz). Smaller 6–7 cm mugs suit espresso and children; 12 cm and larger work as soup mugs or for serving.

Enamel mug sizes are usually given in centimeters of diameter rather than in ounces. Capacity also depends on height, so always check the product details. The table below gives typical ranges.
