11 oz: our standard mug size
The 11 oz mug is the standard size in our range. It holds 0.33 l, stands 3.74 in high and has a diameter of 3.15 in. It is the size most people picture when they think of a classic coffee mug: easy to hold and right for a regular coffee.
15 oz: more room in the same shape
The 15 oz mug holds 0.44 l. At 4.61 in high with a diameter of 3.43 in, it gives you a third more coffee and a wider surface for the design that wraps around the outside.
11 oz vs 15 oz mug: which one should you choose?
- Choose 11 oz if you drink one regular coffee at a time and like a mug that feels compact in your hand.
- Choose 15 oz if you like a generous pour, or if you want the design to have more space.
What stays the same in both sizes
Both mug sizes are made of durable white ceramic with a glossy finish and a comfortable C-handle. Both are microwave-safe and dishwasher-safe, and the ceramic is lead and BPA-free. The only difference is how much they hold.
