8 cm tall X 15 cm wide at top X 13 cm wide at base.
Height 4 1/2 cm x 12 cm diameter at the top x 10 cm diameter at the base.
or roughly: 1 3/4 inches tall x 4 3/4 inches diameter at the top x 4 inches diameter at the base.
If these measurements are correct, this lower example is the smallest kettle I have come across so far!
My copy of a period kettle.
12 cm tall x 18 cm diameter at the top x 13.5 cm diameter at the base.
So if I were to cut the height of this kettle down to 8 cm tall, this would be pretty much the same size as the first kettle at the top.
