Here comes the dreaded answer... it depends. Usually, you can start with about 4-5 small pieces of wood to get your fire going and your oven up to temperature. The Alfa box contains 10-12 pieces of wood, each about 12 inches long.
Depending on your oven's heat retention (ie, brick ovens hold heat better than stainless ovens) and how long you are cooking, you may only need to add a few other pieces of wood to maintain the temperature or you might need to continually add a piece of wood as necessary while you are cooking pizzas.
A box of wood should last for at lease 2 firings.
