Lunch buyers choosing a portion
Decide whether crisps are a small side or a larger snack, then check the weight of the individual bag rather than relying on its appearance.
Who is this for?
Shoppers comparing nutrition labels
Compare calories, fat, saturates, sugars and salt for the amount you expect to eat, especially when the bags are different sizes.
Shoppers with dietary requirements
Check the declaration, ingredients and allergen advice for the exact flavour and pack you intend to buy.
What should you check?
Choose a portion for your lunch first, then compare the label and the exact product format.
| Priority | What to check | Your needs |
|---|---|---|
| Portion | Check the bag weight, servings per pack and whole-bag kcal. The researched examples include 25g, 40g and 45g individual bags. | If crisps are just a side to my lunch, I may want a smaller bag; for a larger snack, I can compare the bigger portions. |
| Nutrition | Compare calories, fat, saturates, sugars and salt on the same per-pack basis. GOV.UK explains that traffic-light labels show high, medium or low amounts of four nutrients. | I want to know what is in the bag I will eat, not compare differently sized packs by their front designs. |
| Ingredients | Read the exact flavour’s dietary declaration, ingredients and allergen advice. Do not apply one flavour’s information to an entire range. | For a dietary requirement or allergy, I need the information on the pack I am buying. |
| Style and format | Check whether the product is potato or vegetable-based, and whether you are buying one bag or a multipack. Compare the nutrition panel even when crisp styles differ. | I might want a particular flavour or texture, or several individual bags to put aside for future lunches. |
Common buying mistakes
-
Treating every individual bag as the same portion
The researched bags range from 25g to 45g. Tesco Groceries lists 128 kcal for a Seabrook Sea Salted 25g bag and 238 kcal for a McCoy's Salt & Vinegar 45g bag; those are different products as well as different portions.
Compare net weight, servings per pack and whole-bag kcal before choosing.
-
Judging nutrition by crisp style
Vegetable-based or hand-cooked does not tell you the amounts of sugars, fat or salt. Tesco Groceries lists 9.4g sugars per 40g bag of Tyrrells Mixed Root Vegetable Crisps.
Choose the style you prefer, then compare its pack nutrition with the alternative you would buy.
-
Assuming dietary details apply across a brand
Kettle Chips lists Lightly Salted as suitable for vegans, while its Mature Cheddar & Red Onion ingredients include milk products. Flavour-specific ingredients matter.
Check the current pack’s ingredients and allergen advice, particularly if you have an allergy or intolerance.
-
Relying on a particular bag for a meal deal
Retailer snack eligibility and stock can change, so a preferred crisp bag may not be an option for a particular lunch purchase.
Check the retailer’s current listing and meal-deal terms before you choose your lunch.
Brand and product references
These examples illustrate pack sizes and label differences; a brand name alone does not establish the details of every flavour.
Walkers
Ready Salted appears in both a 45g grab bag and 25g nutrition information.
- Tesco Groceries lists 234 kcal, 14g fat and 0.54g salt per 45g Ready Salted bag.
- Walkers’ 25g Ready Salted figures describe a different portion; check which pack size you have.
Tyrrells
Mixed Root Vegetable Crisps provide a 40g vegetable-crisp example.
- Tesco Groceries lists the 40g bag as vegan and gluten-free, with 4.5g fibre per bag.
- The same bag lists 209 kcal and 9.4g sugars; compare its full panel rather than judging it by its ingredients.
Kettle Chips
Lightly Salted is a 40g bag with product-specific dietary declarations.
- Tesco Groceries lists it as gluten-free, vegan and kosher, with 198 kcal and 0.26g salt per bag.

Seabrook
Sea Salted comes as individual 25g bags in a researched 6-pack format.
- Tesco Groceries lists 128 kcal and 0.33g salt per 25g bag.

- The whole pack lists 238 kcal, 14g fat and 0.95g salt, with high front-of-pack labels for fat and salt.

REAL’s direct shop lists 35g bags in case and pub-card formats for stocking several lunches.

Frequently asked questions
What size crisp bag should I choose with lunch?
Choose by the part crisps will play in your lunch: a 25g bag is a smaller side, while the researched 40g and 45g bags provide larger portions. Check the whole-pack nutrition as well as the weight, because values vary between products.
Should I compare nutrition per 100g or per bag?
Use per-bag figures to see the amounts in the portion you plan to eat. Per-100g figures offer a further way to compare products when their bag sizes differ.
What does a traffic-light label show?
GOV.UK explains that it shows whether fat, saturates, sugars and salt are high, medium or low, alongside energy information. Read it with the serving or pack quantity so you know which amount the figures describe.
Can I rely on a brand name for vegan or allergen information?
No. Check the exact flavour’s current ingredients and allergen advice. Kettle Chips lists Lightly Salted as suitable for vegans, while ingredients listed for its Mature Cheddar & Red Onion flavour include milk products.
