You can get a whole pizza for $5?
For traditional toppings like mushrooms, pepperoni, sausages or anchovies add something between 0.5 and 1.5 euros.
That's for a take out or a delivery (it might sound strange but pizza being delivered costs a little bit less per sé, because it's considered of a lower quality, pizza should be eaten fresh from the oven, but add the delivery fee and the prices are more or less the same)
If you sit at a restaurant, it's usually a couple euros more.
And I'm talking about the prices I actually pay in Rome, in the city centre, I live at 5 minutes walking distance from the Colosseum.
On deliveroo, 7-9 euros for something that’s easily 3x higher quality and taste than in the US

You will find a great variety of pizza sizes, from the giants to the tiny, I for example prefer smaller pizzas, I don't like feeling bloated after eating a big one, but the price is always the same (more or less, you can pay 15 euros for a pizza in Italy, but it's not the norm )
If you refer to the fact that pizza is usually shared in US, we have a different kind of pizza for that, it's called pizza al taglio (sliced pizza, but it's not really the same thing) and you can have an entire pan for 12-18 euros, but at least 4-5 people can feed on it and you can have different toppings
