Picnic hosts sharing a pizza
Compare kcal per 100g across different pizzas, then look at the labelled serving. A half-pizza serving is useful for planning, but it may not match the slices each person takes.
Who is this choice for?
The useful comparison depends on how much pizza you plan to serve and what will happen to it between cooking and eating.
Shoppers comparing calories
Check the exact pizza’s energy figures alongside saturated fat and salt. A vegetable topping or thin crust tells you what the pizza is like, not how its nutrition panel compares with another product.
People taking cooked pizza outdoors
Plan where the pizza will be cooked and how perishable food will be kept cool at the picnic. The Food Standards Agency advises using a cool box or cool bag with ice or frozen gel packs.
What should you check before choosing?
Start with a like-for-like nutrition comparison, then decide whether the labelled portion and the practicalities of serving it outdoors fit your plans.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portions | Compare kcal per 100g, then kcal per labelled serving. Check whether that serving is half a large pizza or one individual pizza, and consider how much you will actually eat. | I’m sharing a pizza, so I want a per-100g comparison without assuming everyone will take the same number of slices. |
| Saturated fat and salt | Read both values per 100g and per serving on the exact pack. Tesco Groceries lists 1.69g salt per half of its Stonebaked Vegetable Pizza, illustrating why the calories alone do not describe the portion. | A lower calorie figure is not my only consideration; I want to see what else is in the portion I plan to serve. |
| Cooking and cooling | Follow the pack’s cooking instructions before serving. For perishable food at a picnic, the Food Standards Agency advises a cool box or cool bag with ice or frozen gel packs. | If the pizza will travel after cooking, I need a workable way to keep it cool until it is needed. |
| Ingredients and allergens | Read the current ingredient and allergen declaration for each variant, particularly when choosing for a group. Do not assume that pizzas with similar names have identical ingredients. | Someone in our group may need to check the exact pizza’s ingredients before we buy it. |
Common mistakes to avoid
-
Assuming thin crust means fewer calories
Crust style alone does not establish a lower energy figure. Tesco Groceries lists 200kcal per 100g for its Stonebaked Vegetable Pizza and 238kcal per 100g for Goodfella's Stonebaked Thin Margherita.
Compare the exact products’ kcal per 100g, then check their labelled portions before deciding how much to serve.
-
Looking at calories but not the rest of the label
Calories do not tell you how much saturated fat or salt a serving contains. ASDA Groceries lists 10g saturates and 2g salt for a quarter of Chicago Town Stuffed Crust Loaded Pepperoni Pizza.
Check saturated fat and salt for the portion you expect to eat, as well as the per-100g figures used to compare products.
-
Treating a labelled serving as everyone’s portion
A half of a large pizza and one whole individual pizza are different serving formats. Tesco Groceries labels one Chicago Town Deep Dish Pepperoni pizza as a 433kcal serving.
Work out whether the pizza is for one person, for sharing or for slices alongside other picnic food, then compare that plan with the label.
-
Leaving cooked pizza out during the picnic
Cooking the pizza before leaving does not remove the need to plan how perishable food will be kept cool outdoors.
Follow Food Standards Agency advice to use a cool box or cool bag with ice or frozen gel packs, and take food out when it is needed.
Brand and own-label examples
These figures describe the named pizzas, not every product made by each brand. Check the current pack when comparing variants or planning portions.
Tesco
Tesco Groceries lists its Stonebaked Vegetable Pizza at 200kcal per 100g and 349kcal per half pizza.
- Its stated per-100g figure gives a point of comparison with the other named pizzas in this article.
- The labelled half pizza also contains 1.69g salt, so compare more than its calorie figure.
Goodfella's
Tesco Groceries lists the 334g Stonebaked Thin Margherita Three Cheese Pizza at 238kcal per 100g and 394kcal per half pizza.
- The half-pizza figure can help when planning to share it.
- That labelled half contains 7.6g saturates; a thin base is not a reason to skip the nutrition panel.
Dr. Oetker
Sainsbury's lists Ristorante Mozzarella Pizza at 240kcal per 100g and 432kcal per half pizza.
- The named Mozzarella variant has both per-100g and half-pizza figures for comparison.
- The Pepperoni-Salame variant has different figures: Sainsbury's lists 280kcal per 100g and 462kcal per half pizza.
Chicago Town
The Deep Dish Pepperoni two-pack uses individual pizzas: Tesco Groceries lists one cooked pizza as one 433kcal serving.
- A whole individual pizza gives picnic hosts a clearly labelled serving format.
- Tesco Groceries lists it at 265kcal per 100g, compared with 200kcal per 100g for its Stonebaked Vegetable Pizza; the individual format does not itself mean fewer calories per 100g.
Sainsbury's
Sainsbury's lists its Vegetable Pizza at 217kcal per 100g and 419kcal per half pizza.
- The per-100g and half-pizza figures allow two different portion checks.
- Its labelled half contains 1.74g salt, which remains relevant when comparing picnic portions.
Asda
ASDA Groceries lists its Double Pepperoni Stonebaked Pizza at 288kcal per 100g and 412kcal per half pizza.
- The named product provides both per-100g and half-pizza energy figures.
- Its 288kcal per 100g exceeds the figures listed here for the Tesco and Sainsbury's vegetable pizzas; compare portions and other label values too.

Frequently asked questions
How do I compare calories in pizzas of different sizes?
Compare kcal per 100g first, then check the labelled serving against the amount you expect to eat. The NHS explains that nutrition information is given per 100g and sometimes per portion; a labelled portion need not be the portion you serve.
Is a thin-crust frozen pizza necessarily lower in calories?
No. Tesco Groceries lists Goodfella's Stonebaked Thin Margherita at 238kcal per 100g and its Stonebaked Vegetable Pizza at 200kcal per 100g. Compare the exact products and intended portions rather than choosing by crust style alone.
Can I take cooked frozen pizza to a picnic?
Yes, if you plan how to cook it and keep perishable food cool until it is needed. The Food Standards Agency advises taking a cool box or cool bag with ice or frozen gel packs.
Should I cook frozen pizza before taking it outdoors?
Yes. Follow the instructions on the exact pack and check that the pizza is thoroughly cooked before serving. If it will be eaten later at the picnic, plan how to keep the cooked food cool during the outing.
