Snackers planning a defined portion
If you want to know the calories before a long film starts, an individual bag makes the quantity straightforward to identify. Compare its labelled calories and weight, rather than choosing by flavour alone.
Who is choosing crisps for movie night?
Buyers comparing salt as well as calories
Salt can change the choice even between similarly sized bags. Walkers labels Lightly Salted at 0.17g salt per 25g bag and Ready Salted at 0.34g per 25g bag; their labelled calories are 132 and 130 kcal respectively.
Hosts checking guests’ dietary requirements
Check the exact flavour and current pack before serving it. Ingredients, allergen statements and dietary-suitability labels can differ between products, including flavours sold under the same brand.
What should you compare on the pack?
Start with the amount you expect to serve, then compare the label for that amount. Calories per bag, calories per 100g and salt per bag answer different questions.
| Priority | What to check | Your needs |
|---|---|---|
| Individual portion | Check the bag weight and labelled kcal per bag. Joybuy labels Walkers French Fries Ready Salted at 78 kcal per 18g bag; Seabrook Crisps labels its Lea & Perrins potato crisps at 126 kcal per 25g bag. These are different snack formats and serving sizes. | I want one bag whose labelled quantity matches what I plan to eat during the film, and I want to know whether it is a sliced crisp or another potato snack. |
| Sharing portions | Check the sharing bag’s total weight, its stated serving size and its kcal per 100g. KETTLE Chips labels Sour Cream & Sweet Onion at 507 kcal per 100g; the reviewed format is a 130g bag. | If a bowl will be shared, I would rather serve a portion deliberately than treat the whole bag as one serving. |
| Salt | Compare salt for the same stated quantity where possible. Walkers labels its Lightly Salted crisps at 0.17g per 25g bag and Ready Salted at 0.34g per 25g bag; their calorie figures do not follow the same order. | Salt matters to my choice alongside calories, so I need to compare both figures on the pack. |
| Ingredients and allergens | Read the current pack’s ingredients, emphasised allergens and any precautionary allergen statement. Check dietary-suitability claims for the exact flavour. The Food Standards Agency says allergens present in prepacked food must be emphasised in its ingredients list. | When buying for guests, I need to check each flavour against their requirements rather than assume every crisp in a range has the same ingredients. |
Which buying mistakes are easy to make?
-
Comparing per-100g calories, then eating the sharing bag
A per-100g value is a comparison measure, not a cap on what you consume. KETTLE Chips labels the reviewed Sour Cream & Sweet Onion crisps at 507 kcal per 100g, and the bag format is 130g.
Check the serving information and put the amount you intend to eat into a bowl before the film, or choose an individual bag.
-
Reading “lower fat” as “lower calorie”
Tyrrells states that its lentil crisps have 30% less fat than standard potato crisps on the brand’s stated comparison basis. Its Sour Cream & Onion lentil crisps are labelled at 141 kcal per 30g serving, and they are not potato crisps.
Compare kcal for the amount you intend to eat, as well as fat and the type of snack you want.
-
Assuming less salt also means fewer calories
Walkers labels Lightly Salted at 0.17g salt and 132 kcal per 25g bag, compared with 0.34g salt and 130 kcal for its Ready Salted crisps.
Use the salt figure to decide on salt and the calorie figure to decide on calories; one does not stand in for the other.
-
Assuming a flavour’s ingredients from its name
Flavoured crisps can have different ingredient and allergen statements, so a general impression of a brand or flavour is not enough when buying for someone with a dietary requirement.
Read the exact current pack, including its ingredients, highlighted allergens and precautionary wording.
What do the relevant brands offer?
These brand examples show why pack format and the exact product label matter more to this decision than a brand name alone.
Walkers
Walkers offers conventional potato crisps in individual bags alongside potato-snack formats.
- Walkers labels Ready Salted at 130 kcal per 25g bag and Lightly Salted at 132 kcal and 0.17g salt per 25g bag.
- The 78 kcal figure for French Fries Ready Salted applies to a smaller, 18g potato-granule snack bag, not a 25g sliced-potato crisp bag.
Seabrook
Seabrook has individually bagged conventional potato crisps, including plain and flavoured varieties.
- Seabrook Crisps labels Lea & Perrins Worcestershire Sauce at 126 kcal per 25g bag.
- Its Sea Salted bag is a different size, at 31.8g and a labelled 164 kcal per bag. Check the weight before comparing bag totals.
Tyrrells
Tyrrells sells potato crisps in several bag sizes and also has a separate lentil-crisp range.
- Tyrrells lists its Lightly Sea Salted potato crisps in 40g, 150g and 600g formats, giving buyers different quantities to portion.
- A fat comparison for Tyrrells lentil crisps does not establish a lower-calorie potato-crisp choice; its Sour Cream & Onion lentil variety is labelled at 141 kcal per 30g serving.
KETTLE Chips
The reviewed KETTLE Chips product is a larger sharing format rather than an individual bag.
- KETTLE Chips gives a per-100g nutrition figure for its Sour Cream & Sweet Onion crisps: 507 kcal.
- For the reviewed 130g bag, decide how much to serve before using that figure to assess a movie-night portion.
Pipers
Pipers describes its potato crisps as strongly flavoured, with seasonings chosen for individual varieties.
- The flavour range offers a consideration for buyers choosing by seasoning.
- For a calorie-based choice, check the nutrition and bag weight of the particular Pipers product you intend to serve.
REAL Hand Cooked Crisps
REAL Hand Cooked Crisps offers potato-crisp flavours, including a Sea Salt product.
- The listed Sea Salt ingredients are potatoes, vegetable oils and sea salt; the reviewed case contains 24 × 35g bags.
- Compare nutrition for one 35g bag with the portion you intend to eat, rather than comparing a case with a single smaller bag.
Joybuy crisps and potato snacks to consider
These options include individual bags of Walkers potato crisps and smaller potato-snack formats. For movie night, use the weight and nutrition of the exact flavour and pack you choose; a figure for another flavour or multipack is not interchangeable.

Walkers Salt & Shake Crisps 6 × 24g
The six 24g bags offer an individual-bag format for planning movie-night portions. Check the current pack’s calorie, salt and allergen information when deciding whether this variety suits your needs.
Image unavailable
Walkers Ready Salted Crisps 6 × 25g
These 25g bags suit a plan to serve one conventional ready-salted crisp pack per person. Walkers labels Ready Salted at 130 kcal and 0.34g salt per 25g; check the current pack’s allergen statement before serving.
Image unavailable
Pom-Bear Original Potato Crisps 12 × 13g
The 13g bags provide a smaller stated quantity than the 24g and 25g Walkers crisp bags shown here. Compare calories per bag on the current label, and check that this potato-snack format is the one you want.
Image unavailable
Walkers BBQ Crisps 6 × 25g
This flavoured option comes as six 25g bags, making the pack quantity easy to compare with a plain 25g crisp bag. Check the BBQ flavour’s own calories, salt and ingredients rather than using another Walkers flavour’s figures.
Image unavailable
Walkers French Fries Variety 6 × 18g
The 18g bags are a smaller-format alternative to conventional 25g potato-crisp bags. This is a variety multipack: check each flavour’s own nutrition and allergen label rather than applying the Ready Salted flavour’s figures to every bag.
Movie-night crisp questions
Should I compare calories per bag or per 100g?
Compare calories for the amount you expect to eat. Per-100g figures help compare products on a common weight basis, but a bag’s calories depend on its size: Walkers labels French Fries Ready Salted at 78 kcal per 18g bag, while the reviewed conventional 25g potato-crisp bags are labelled at 126–132 kcal. French Fries is a different potato-snack format, not a sliced potato crisp.
Can a sharing bag fit a planned movie-night portion?
Yes, if you serve the quantity you intend to eat rather than treating the bag as one portion. The reviewed KETTLE Chips Sour Cream & Sweet Onion format is 130g and labelled at 507 kcal per 100g, so check the amount you put in the bowl.
Which of the reviewed Walkers crisps has less salt?
Walkers labels Lightly Salted at 0.17g salt per 25g bag, compared with 0.34g for Ready Salted in the same bag size. Their labelled calorie figures are 132 and 130 kcal respectively, so choose according to the figure that matters to your comparison.
Is a plain or vegan-labelled crisp necessarily suitable for someone with an allergy?
No: check the exact current pack’s ingredients, highlighted allergens and any precautionary statement. The Food Standards Agency says prepacked food must have an ingredients list in which allergens present are emphasised; a flavour name or vegan label does not replace that check.
Do lower-fat lentil crisps provide a lower-calorie potato-crisp choice?
Not on the fat claim alone, and lentil crisps are not potato crisps. Tyrrells states that its lentil crisps have 30% less fat than standard potato crisps on its stated comparison basis, while its Sour Cream & Onion lentil variety is labelled at 141 kcal per 30g serving. Compare calories for the portion you would actually eat.
