Generally, the hotter the oven, the better the pizza will be. Place a pizza stone on a lower oven rack. Preheat the oven between 450 and 500 degrees F (250 to 260 degrees C) — the stone needs heat up while the oven heats. Large, thick-crusted pizzas might need an oven temperature closer to 400 degrees F (200 degrees C) so the crust can cook completely before the toppings burn.
