Pan size not only affects how much you can put in it but also how it cooks in your oven depending on the amount of space your bakewares uses. Knowing what pan size to use will help you achieve baking success.
For traditional cake pans and pie plates (or dishes), the pan size can be found by turning the pan over and measuring across the bottom.
Determine the volume of dishes by filling them with water and then measuring the water. For example, if your cake pan holds approximately 8 cups/2000 ml then it will be suitable for a recipe calling for a 2 L cake pan.
Correct Pan Size
Before you buy large bakeware, you may want to measure your oven racks. You’ll want to ensure your new bakeware will not only fit inside your oven but also leave room to allow air to circulate around it.
For instance, baking sheets should have two inches of room on each side for air to circulate. A standard 30-inch oven has a 22-inch wide rack which leaves room for an 18-inch wide sheet.
Converting Round Pans to Square
The volume of round pans and square pans are different. Changing the shape asked for in a recipe will require a similar volume pan in the other shape.
Below are some conversions for switching between round and square pans:
- 12 cm (5in) square = 15 cm (6in) round
- 15 cm (6in) square = 18 cm (7in) round
- 18 cm (7in) square = 20 cm (8in) round
- 20 cm (8in) square = 23 cm (9in) round
- 23 cm (9in) square = 25 cm (10in) round
- 25 cm (10in) square = 28 cm (11in) round
- 28 cm (11in) square = 30 cm (12 in) round
- 30 cm (12 in) square = 33 cm (13in) round
