There are no hard rules for sizes and Teacups can of course vary plus it depends on how you pour! As a guide an average Teacup is said to contain 150ml when filled to 1.5cm of the rim. Thus Teapots sized up to 0.6L pour 3-4 cups, up to 1L 5-6 cups, up to 1.2L 7-8 cups, up to 1.5L 9-10 cups and our largest 2.0L 12-13 cups. If in doubt check the size of your Teacup first and remember with a Mug you will get half the number of Cups!
