Shoppers who may eat a whole pizza
If you expect to eat more than one labelled portion, work out the calories for that amount before choosing between pack sizes.
Who needs to plan portions?
Portion planning matters most when the amount served at a Bonfire Night meal may differ from the portion printed on the pack.
Households sharing pizza
A per-half or per-quarter value can help you plan servings for a group. Check how many of those portions the pack contains.
Shoppers with dietary requirements
Check the exact product’s ingredients, allergens and suitability wording first. Then compare its calories, saturated fat and salt for the portion you intend to serve.
What should you compare?
Start with your likely portion, use per-100g figures to compare different-sized pizzas, then check the rest of the label.
| Priority | What to check | Your needs |
|---|---|---|
| Calories eaten | Compare kcal per 100g, calories per labelled serving and servings per pack. Add up the servings you expect to eat. | If I am likely to eat the whole pizza, the half- or quarter-pizza figure alone will not describe my meal. |
| Pack and crust | Check pack weight and serving count before comparing thin, stonebaked or stuffed-crust pizzas. The crust description does not establish the calorie total. | A larger pizza may suit sharing, but I need to decide how much each person will actually have. |
| Saturated fat and salt | Read the values for your intended portion as well as any traffic-light indicators. The Food Standards Agency’s label guidance explains that traffic lights help compare nutrients at a glance. | I want to compare more than calories when choosing between pizzas for the same meal. |
| Dietary suitability | Check the current ingredients and allergen statement on the exact pack. Treat gluten-free or vegetarian wording separately from its nutrition values. | If someone needs a suitable pizza, I cannot assume that its dietary label also means fewer calories. |
Common buying mistakes
-
Reading a portion value as the whole-pizza value
Tesco Groceries lists 423 kcal per quarter of Chicago Town Large Takeaway Cheese Pizza. Four such quarters amount to 1,692 kcal using the labelled portion value.
Check the serving count and calculate the amount you plan to eat. If you expect a whole pizza, compare whole-pack totals too.
-
Assuming thin or gluten-free means fewer calories
Tesco Groceries lists different per-half calorie values for Goodfella’s two thin pizzas, while Sainsbury’s lists 376 kcal per half of its Free From Margherita. Format and dietary suitability do not replace the nutrition panel.
Check kcal for your intended portion on the exact topping and pack, alongside its saturated-fat and salt values.
-
Looking only at calories
The Food Standards Agency’s traffic-light guidance also covers nutrients such as saturated fat and salt. Tesco Groceries lists 9g saturates per quarter of Chicago Town Large Takeaway Cheese Pizza.
When comparing pizzas for the same planned portion, read their saturated-fat and salt information as well as energy.
-
Relying on an old online label
Ingredients and nutrition information can change, which matters particularly when someone needs to avoid an allergen.
Use listings to narrow your choices, then check the current pack’s serving count, nutrition panel, ingredients and cooking instructions before serving.
Brand and product references
These figures describe the named pizzas, not every product from each brand; check the current pack when shopping.
Tesco
Tesco Stonebaked Margherita is a smaller-pack example for comparing portion and whole-pizza calories.
- Tesco Groceries lists a 252g pack, 335 kcal per half pizza and 260 kcal per 100g. Two labelled halves amount to 670 kcal.
- The lower whole-pack total does not mean it has the lowest kcal per 100g among these examples.
Goodfella’s
The Stonebaked Thin pizzas show why toppings and portion values still matter within one format.
- Tesco Groceries lists 238 kcal per 100g and 394 kcal per half for Three Cheese Margherita, versus 251 kcal per 100g and 417 kcal per half for Thin Pepperoni.
- A thin base alone does not tell you the calories in the amount you will eat.
Chicago Town
The Large Takeaway Cheese Pizza illustrates the importance of portions when considering a sharing-sized pizza.
- Tesco Groceries lists 423 kcal per quarter, a usable figure when the pizza is divided into quarters.
- The same listing gives 9g saturates per quarter; eating several quarters changes the meal total substantially.
Sainsbury’s
Free From Margherita is a dietary-suitability example rather than a lower-calorie claim.
- Sainsbury’s labels this pizza gluten free and suitable for coeliacs.
- Its listing gives 271 kcal per 100g and 376 kcal per half pizza, with saturated fat marked high per half.
Frozen pizzas on Joybuy
These options include two thin stonebaked pizzas and two larger stuffed-crust pizzas. Compare the portion you expect to eat; a product’s format alone does not establish its meal calories.

Goodfella’s Margherita Stonebaked Thin 334g
For a shared pizza or a planned half-pizza portion, Tesco Groceries lists 394 kcal per half and 238 kcal per 100g for this 334g Stonebaked Thin Margherita. Two labelled halves amount to 788 kcal; also check saturated fat, salt and the current allergen statement.

Goodfella’s Pepperoni Stonebaked Thin 332g
If you prefer pepperoni, compare its portion value rather than assuming it matches the Margherita. Tesco Groceries lists 417 kcal per half pizza and 251 kcal per 100g for this 332g Stonebaked Thin Pepperoni; check the current pack’s allergens before serving.

Chicago Town Takeaway Stuffed Crust BBQ Chicken, BBQ Sauce Filled Crust 668g
This 668g stuffed-crust pizza calls for portion planning if it is being shared. Check its current label for the calories, saturated fat and salt in the amount each person will eat; do not apply figures from Chicago Town’s different Large Takeaway Cheese Pizza to this BBQ Chicken variant.

Chicago Town Takeaway Stuffed Crust Sweet Honey BBQ Salami 635g
For this 635g stuffed-crust pizza, decide how the pack will be divided before comparing it with a smaller pizza. Use the current pack’s serving count and nutrition panel to assess your planned portion, and check its allergen statement for the group.
Frozen pizza questions
Should I compare calories per 100g or per serving?
Use both: kcal per 100g helps compare differently sized pizzas, while the serving value helps you calculate the calories in the amount you expect to eat. Check how many labelled servings make up the pizza if you may have more than one.
Is a thin frozen pizza automatically lower in calories?
No. Tesco Groceries lists 394 kcal per half pizza for Goodfella’s Stonebaked Thin Three Cheese Margherita and 417 kcal per half for its Thin Pepperoni. Check the exact topping, pack and planned portion rather than relying on the word “thin”.
Does gluten-free mean a pizza has fewer calories?
No. Gluten-free describes dietary suitability, not calorie content. Sainsbury’s lists its Free From Margherita as suitable for coeliacs and gives 376 kcal per half pizza; compare its nutrition panel separately from its suitability label.
What should I check besides calories?
Check saturated fat and salt for the portion you intend to eat. The Food Standards Agency’s traffic-light guidance explains how front-of-pack colours help compare nutrients; use the figures on the current product label when choosing between pizzas.
What if someone eating the pizza has an allergy or needs a gluten-free option?
Check the exact pack’s ingredient list, allergen statement and dietary-suitability wording before cooking. Sainsbury’s specifically labels its Free From Margherita gluten free and suitable for coeliacs; do not assume another pizza has the same suitability because it looks similar.
