Some pizza styles make their personality known before you even take a bite. Neapolitan arrives soft, blistered, and alive — you fold it, you eat it fast. Pizza al taglio hands you a slab wrapped in paper, made for Roman streets. Then there is Pizza Romana Tonda: round, thin, crisp, and quietly sure of itself.
At 170 Grammi Pizzeria, it is not a style we landed on by accident. It sits at the centre of what we do — not because it is fashionable, but because it suits the way Sydneysiders actually eat. Shared plates. Long tables. The kind of dinner that stretches across a few hours without anyone feeling too full to order dessert.
What Is Pizza Romana Tonda?
The name is literal: tonda simply means round. The label exists to separate this style from other Roman formats — pizza al taglio chief among them — which are baked in trays and sold by the rectangular slice.
But the shape is the least interesting thing about it. What defines Pizza Romana Tonda is structure. The base is thin and stretched, baked until it has real snap, designed to hold its form from the moment it leaves the oven to the last slice on the board. Where a Neapolitan pizza invites you to chase a soft, pillowy cornicione, Roman round pizza is more composed. The crust is restrained. The base does the heavy lifting — or rather, the light lifting.
For anyone used to soft, foldable pizza, the difference is immediate. A slice should lift cleanly, carry its toppings without drama, and deliver a crisp bite that does not tip into dry or brittle territory. It is firmer. Neater. More considered.
Why Roman Round Pizza Feels So Different at the Table
The difference is not just textural — it is structural, and it shapes the whole experience of eating.
Because the base is thin and crisp, it does not dominate the meal. It gives the table room to breathe. You can open with antipasti, move through two or three pizzas, add a pasta, pour another glass, and still feel like the evening has momentum. Nothing collapses. Nothing weighs you down.
Toppings stay where they belong. San Marzano tomato tastes bright. Fior di latte sits creamy on the surface rather than pooling into the dough. Guanciale, pecorino, artichoke, basil — everything reads clearly. When the base is too soft, flavours blur together. When it is too hard, the whole thing feels like a cracker. Pizza Romana Tonda sits squarely between the two: crisp enough to define each bite, considered enough to carry flavour with some elegance.
That balance is particularly well-suited to Surry Hills dining, where a night out can be casual, celebratory, spontaneous or somewhere between all three. The pizza holds its shape while conversation moves around it.
For a broader look at how this style sits within Roman pizza culture, our guide to what makes Roman pizza different is worth a read before your first visit.
The Crunch Is a Consequence, Not the Point
Crispness is the most obvious feature, but it is not the goal in itself. A great Roman base should have contrast — the kind you notice without consciously analysing it. The outside snaps; the inside still has enough air and structure to feel refined rather than hollow.
That distinction matters. A pizza that is all crunch and no depth can feel punishing after two slices. Pizza Romana Tonda should invite the third. The base is doing quiet work: holding its shape, supporting toppings, staying dry without going brittle. It is the kind of precision that disappears when it is done well and announces itself loudly when it is not.
How the Dough Gets There
Behind the simple round shape is a technical process. Roman pizza relies on control at every stage — hydration, fermentation, handling, bake temperature — and each decision leaves a mark on the finished base.
Hydration and Lightness
Hydration shapes how the dough opens, stretches, and bakes. The aim is a base that crisps cleanly while still feeling light in the mouth — not a biscuit, not a flatbread, not something that sits in your stomach like a paving stone. Handled well, a well-hydrated dough develops an open, airy internal structure that explains why many diners describe Roman pizza as easier to eat across a long, shared meal.
Fermentation and Flavour
Fermentation gives dough time to develop depth before a single topping is added. A rushed dough can still bake. It will not taste the same. Longer, controlled fermentation also builds the structural quality the base needs: it has to crisp cleanly, hold its shape under heat, and stay balanced once toppings go on.
Our piece on why Roman pizza feels lighter goes into more detail on the relationship between fermentation, texture, and the way the pizza eats over the course of a meal.
The Bake
The final character comes from the oven. Heat has to create crispness without burning away the balance — a dry, clean finish where the base feels precise from edge to centre, and the toppings still taste fresh. This is where Roman pizza becomes less about spectacle and more about discipline. There is no drama in a well-baked Roman base. The beauty is in how neatly everything holds together.
Pizza Romana Tonda vs Pizza al Taglio
The confusion is common and completely understandable: both are Roman, both are beloved, and both involve a very good relationship with a hot oven.
Pizza al taglio is baked in rectangular trays, sold by weight or cut, and deeply embedded in Roman street food culture. It is casual and flexible and made for eating on the move. Pizza Romana Tonda is round, usually served whole, and more naturally at home in a sit-down pizzeria setting.
Neither is more authentic. Rome has always had room for both. One is for quick variety on a Tuesday lunch; the other is for the rhythm of the table — ordered whole, sliced, shared, and enjoyed alongside drinks, antipasti and conversation that goes longer than planned.
What to Pay Attention To When You Eat It
The best way to understand Pizza Romana Tonda is to slow down for the first slice. Lift it and notice how it holds — no sagging, no drooping toppings. Listen for the bite. Watch how each ingredient sits clearly on the surface rather than sinking into a soft layer of dough beneath it.
Then notice the finish. A good Roman pizza should not leave you feeling heavy after two slices. It should make you want another taste, another topping, another shared plate from somewhere else on the table. The experience is crisp, clean and generous without tipping into excess.
That is the quiet appeal of Pizza Romana Tonda. It is not trying to compete with other traditions. It offers a different kind of pleasure: lighter in feel, sharper in texture, and deeply satisfying when it is made with care.
A Roman Style With a Sydney Table in Mind
Pizza Romana Tonda proves that round pizza does not have to play by one set of rules. It can be thin without being plain, crisp without being harsh, and traditional without feeling like a museum piece.
For 170 Grammi, the style is how we express Roman pizza culture in Sydney with some honesty: a crisp base, balanced toppings, and a dining experience built around sharing rather than spectacle. Roman by technique. Generous by spirit. Distinctive from the very first bite.

Frequently Asked Questions
It means round Roman pizza. Tonda is Italian for round, and the name separates this style from rectangular Roman formats like pizza al taglio.
No. Pizza Romana Tonda is round and served whole, while pizza al taglio is baked in trays and sold by the slice or weight. Both are Roman styles, but they suit different settings and occasions.
Yes. The base is thin, structured, and baked to a clean crispness. It holds its shape when sliced and delivers a firm, clear bite — not brittle, but definitely not soft.
Neapolitan pizza is softer with a puffier, charred cornicione. Pizza Romana Tonda is thinner, crisper and more structured, with less focus on the crust edge and more on the overall balance of base and toppings.
A carefully fermented, well-hydrated dough baked to a crisp finish creates a base that does not feel dense or heavy. Most people find they can eat more of it across a shared meal without feeling weighed down.
It is genuinely built for it. The crisp structure makes slicing clean and easy, toppings stay distinct, and the lighter texture means it sits comfortably alongside antipasti, pasta and other dishes without dominating the table.
