Students stocking up for revision breaks
Individual bags make it easier to set aside one snack at a time. Compare how many bags the multipack contains and the weight of each, rather than treating a sharing bag as one portion.
Who is choosing?
The useful pack format depends on whether you want a ready-sized break snack, need to compare nutrition, or must check a particular recipe.
Shoppers comparing salt and fat
Check the figures for the exact pack you will eat. A lower-salt claim and a lower-fat claim describe different comparisons; neither tells you everything about the product’s nutrition.
Households checking dietary labels
Read the ingredient and allergen information for the particular flavour. Seasonings can change whether a crisp is labelled vegan or gluten-free, or carries an allergen warning.
What should you compare?
Start with the amount you intend to serve at each break, then compare nutrition on the same basis and check the exact recipe.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Count the inner bags and note their weight. A sharing bag needs a separate serving decision. | I want one clearly sized snack for each break, without opening a larger bag every time. |
| Portion information | Read the nutrition per inner bag or stated serving, and check how many servings the outer pack contains. Use per-100g figures to compare different bag sizes. | If I choose a sharing bag, I can put the amount I plan to eat in a bowl before returning to revision. |
| Salt and fat | Compare salt and fat for the amount you will eat. Read what a relative claim, such as “less salt”, is compared with. | A lower listed salt amount matters more to me than a baked format, or vice versa; I need to check those as separate features. |
| Ingredients and allergens | Check the exact flavour’s ingredients, suitability statements and allergen warnings on the current packet. | Before buying for someone with a dietary requirement, I need to know whether this particular recipe meets it. |
Common buying mistakes
-
Treating a sharing bag as one snack
Tesco lists nutrition for Kettle Lightly Salted’s 130g bag per 25g serving. Eating more than that serving changes the amount of each nutrient consumed.
Serve the amount you intend to have before starting revision, and put the rest away. An individual-bag multipack removes that portioning step.
-
Reading “less” as a complete nutrition verdict
Tesco’s Walkers Lightly Salted listing compares its salt with the average for regular potato crisps; Waitrose’s Walkers Baked Sea Salt listing makes a separate comparison about fat. Neither claim describes every nutrient in every flavour.
Read the comparison wording, then check salt, fat and calories per pack and per 100g on the product you are buying.
Brand and product-line references
These examples show why pack format and flavour matter more than a brand-wide assumption; check the current label for the product you choose.
Walkers
Its listed options include 6 x 25g Lightly Salted crisps and 6 x 22g Baked Sea Salt crisps.
- Tesco lists 0.15g salt per 25g bag of Lightly Salted; Waitrose lists 96 kcal and 2.8g fat per 22g bag of Baked Sea Salt.
- These are different products and pack sizes. Compare each exact flavour’s label rather than applying either figure across the range.
Seabrook
Tesco lists Sea Salted crisps in a 6 x 25g multipack, labelled gluten-free and suitable for vegans.
- Each 25g bag has a stated portion with 128 kcal and 0.33g salt on the Tesco listing.
- Those nutrition and suitability details belong to Sea Salted; check other flavours separately.
Kettle Chips
Tesco lists Kettle Lightly Salted as a 130g sharing bag and labels that product gluten-free and suitable for vegans.
- The listing gives nutrition per 25g serving, including 124 kcal and 0.16g salt.
- The bag contains multiple servings, so its per-serving figures do not describe the whole bag.
Tyrrells
Tyrrells lists Sea Salt & Cider Vinegar in 40g and 150g bags.
- The brand gives figures for its 40g pack, including 201 kcal and 0.72g salt.
- That recipe includes barley malt vinegar and may contain milk; check its label where those ingredients matter.
McCoy's
McCoy's Salt & Malt Vinegar is a flavoured option with nutrition stated per 100g.
- The brand lists 529 kcal, 31g fat and 2.1g salt per 100g, making the comparison basis clear.
- Its ingredients include barley malt vinegar, and its allergen information includes may-contain warnings. Check the current pack before buying for someone with a dietary requirement.
Real Crisps
Real Crisps lists its Sea Salt flavour in 35g and 150g bags and states that it is suitable for vegetarians and vegans.
- The brand lists potatoes, vegetable oils and sea salt as ingredients for this flavour.
- The 150g format is a sharing bag; choose a serving before a revision break if the amount matters to you.
Joybuy multipack options
These Walkers multipacks offer individual bags for revision breaks, including ready-salted, flavoured and oven-baked variants. Compare the exact flavour and pack label for nutrition and allergens.

Walkers 45% Less Salt Mild Cheese & Onion 6 x 25g
The six 25g bags provide individually sized options for revision breaks. Check the packet for the basis of its “45% less salt” claim, its per-bag nutrition and allergen information; figures for Walkers Lightly Salted do not describe this cheese-and-onion variant.
No image available
Walkers Salt & Shake Crisps 6 x 24g
The 6 x 24g format lets you take one bag for a break. If salt is your deciding factor, check the packet’s preparation instructions and nutrition information for the way you intend to eat it.
No image available
Walkers Ready Salted Crisps 6 x 25g
Six 25g bags provide a ready-salted option in individual portions. Check this variant’s own nutrition and allergen label rather than using figures from another Walkers flavour.
No image available
Walkers Oven Baked Cheese & Onion Crisps Flavour 6 x 22g
The 22g bags give this oven-baked flavour a defined pack size for a break. Compare its own fat and calorie figures with other options: figures for Baked Sea Salt cannot be applied to Cheese & Onion.

Walkers Meaty Variety 20 x 25g
The 20 x 25g format offers more individual bags for repeated breaks. Because it is a variety pack, check the flavours and each relevant ingredient and allergen listing before buying for someone with dietary requirements.
Questions about revision snacks
How do I compare nutrition when crisp bags are different sizes?
Use the per-pack or per-serving figures to understand the amount you plan to eat, then compare per-100g figures across different bag sizes. A 22g bag and a 25g bag are not equal portions, so their per-bag numbers alone do not make an equal-weight comparison. GOV.UK’s traffic-light guidance describes the colours as indicators of whether listed nutrients are low, medium or high.
Does “lightly salted” tell me how much salt is in one bag?
No. Read the salt figure for the exact bag size and the basis of any comparative claim. Tesco lists 0.15g salt per 25g bag for Walkers Lightly Salted, but that figure should not be assumed for another flavour bearing a similar name.
Are sea-salt and vinegar flavours always vegan or gluten-free?
No; check the exact recipe. Tesco labels Seabrook Sea Salted and Kettle Lightly Salted as gluten-free and suitable for vegans, while Tyrrells lists barley malt vinegar in its Sea Salt & Cider Vinegar recipe and warns that it may contain milk. Check the current packet when an allergy or dietary requirement applies.
Can a sharing bag work for a long revision session?
Yes, if you decide how much to serve before you start. Tesco gives nutrition for Kettle Lightly Salted’s 130g bag per 25g serving, not for the whole bag as a single snack; put your chosen amount in a bowl and set the remainder aside.
