OK so I could have measured it but my husband ordered it not me and he likes huge cooking pots because they make bigger portions. It is way to large to store in a cupboard so has to live on the hob - luckily we have six rings and it sits on the one which is too large and never gets used. It does clean up nicely so looks very professional. My previous steamer turned black/brown with use which is why I wanted a replacement as it looked dirty even though thoroughly scrubbed. This is also very lightweight though doesn't feel flimsy for that. I anticipate it will last for many years.
