How Much Pizza Per Person Should You Order?
19 August 2026 · 4 min read
If you’ve ever stood over an order form guessing whether 8 pizzas is too many or way too few for 25 coworkers, you’re not alone. We’ve catered enough Friedrichshain office lunches, birthdays, and team parties at Zia Maria to give you a real number instead of a guess. Here it is, plus the “why” behind it.
2 slices per person
That’s our house rule at Zia Maria, every pizza cut into 3 generous, Roman-style slices.
Our dough rests for days before it bakes and is thin, so a slice is a real meal, not a nibble. Two of those and most guests are genuinely full. That works out to roughly 2 pizzas for every 3 people, simple enough to do the math on the spot.
Quick Reference
| Guests | Slices | Pizzas |
|---|---|---|
| 10 | 20 | 7 |
| 25 | 50 | 17 |
| 50 | 100 | 34 |
| 100 | 200 | 67 |
A Real Order
60 guests, 100 slices, one keg of beer. Textbook math said 120 slices, but with drinks flowing, people graze slower and eat over a longer window. When alcohol’s part of the event, you can often trim 10–15% off the standard count without anyone going hungry.
Does the Crowd Change the Number?
People ask us all the time if an all-male team or a mixed office needs different amounts. Honestly? It usually evens out, 2 slices per person holds up across most groups we cater. What actually shifts the number is the event itself: a seated lunch needs a fuller portion per person, while an evening party where pizza is the main event lets guests graze for hours, so the same total feels more generous.

Before You Book
Flag dietary needs early
Tell us about vegan or vegetarian guests up front, we’ve got great options, but not last-minute.
Pick delivery or pickup first
It changes timing and how we stage the bake so pizza arrives warm.
Mention if timing is loose
“Whenever the meeting wraps” is fine, just tell us so we can plan around it.
Round up for daytime lunches
Evening parties self-correct over hours; a one-hour lunch doesn’t.
Why We Care About This
We’re a Roman-style pizzeria right in Friedrichshain, and this neighborhood runs on pizza parties, offices, studios, and teams just steps from our door. Our goal isn’t to be another delivery option. It’s to be the name Berlin businesses think of first, because we treat catering with the same care as a table for two: fresh dough, real ingredients, and enough food that nobody’s rationing their last slice.
