How many slices in an 18 inch pizza?

Answer 1

The number and size of slices of circular foods eaten from the hand, such as pies, breads, cakes and Pizza, is determined by the circumference and diameter of the food.

The outer crust end of the slice needs to be sufficiently wide as to be held easily in the hand, while not so long from crust to point that the tapering end of the slice sags.

So, the amount and type of topping is a factor in determining how the pizza will be sliced. With a pizza 18in (about 46cm) in diameter, which is a small pizza, six slices would be comfortable with a traditional Italian-style topping with pepperoni; four slices better if the topping has more ingredients and so is heavy.

The thickness of the dough base is also a factor; I'm assuming an Italian-style base, which is not usually thick.

Of course, the number of slices of your pizza can also depend on the number of people sharing it. If you've between two and six sharing an 18" pizza you could cut it into between two and six slices. If it's just you eating it you needn't cut it at all if you're hungry.

If you simply need to estimate how many calories or kilojoules you're eating per slice of pizza, this will vary considerably between products. You can ask the restaurant for an estimate if eating out, or check the packaging if eating at home. If you've made the pizza yourself, you'll have a fair idea how it fits in with your diet.
