Oven sizes
The standard sized single oven is about 60 cm high by 60 cm wide by 60 cm deep (H60 x W60 x D60); the capacity is about 55 litres. Built-in double ovens are usually about 90 cm high. However, there are plenty of other sizes, both built-in and slot-in, such as 70 cm wide, 90 cm wide, or 110 cm wide.
If there is a choice of sizes that you can use, work out how much oven space you'll need when you cook for a maximum number of guests. For instance: for a traditional Christmas dinner, you'll need enough space for the turkey, plus shelves for roast potatoes, and perhaps also for a roast ham. It's better to think big: cooks seldom complain of having too much oven space.
