Have you ever tried making pizza at home and ended up with a soggy mess?  Well, pizza mistakes like this may be a thing of the past.

The Daily Mail reports Dr. Eugenia Cheng from the University of Sheffield created a mathematical formula that ensures a perfectly proportioned pizza every time.

While working with the pizza chain PizzaExpress to work out why its larger, thinner crust 14 inch pizza was proving so popular, compared to its classic 11inch, Cheng calculated a dough to topping ratio based on the thickness of the crust and size of the pizza.

She concluded that even if a person keeps the same amount of dough and topping, the ratio of topping to crust in an average bite changes with the size of the pizza.  Smaller pizzas typically have more topping per bite than larger ones, but larger pizzas give diners a more even spread of toppings per bite.

She used d as the constant volume of dough and t for the constant volume of topping to come up with a mathematical formula for the ratio of topping to base in a median bite, reported the Mail.

She explains the size of the pizza's crust is proportional to the thickness of the pizza - the larger the pizza, the thinner the base.  For larger pizzas, it is important how toppings are arranged. The 14 inch pizza cooks just as evenly as the smaller version, but the topping is spread over a larger area on the 14 inch and goes close to the edge of the pizza.

We're not entirely convinced that you need a mathematical formula to figure this out.  But, it's good to keep in mind that the next time you make pizza at home, make sure you don't overload it with too many toppings.  And when in doubt, check out how Dominos does it.
