Students stocking a new room or shared kitchen
Individual bags give you a stated pack size to compare with a sharing bag. Check the calories for the whole bag if that is the amount you expect to eat.
Who these choices suit
The useful starting point depends on whether you care most about the calories in one bag, salt, or the ingredients in a particular flavour.
Students comparing salt as well as calories
Salt and calories are different figures on the label. A lightly salted option is worth checking for salt, but its name alone cannot tell you how many calories are in a bag.
Students with dietary or allergen requirements
Check the ingredients and allergen statement for the exact flavour. Products from the same brand can have different ingredients and warnings.
What to check before buying
Choose the amount you are likely to eat, then compare its label with other bags of a similar size. Use the per-100g figures when you want to compare the crisps themselves rather than the pack sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Read kcal per pack or serving, the weight in grams, and kcal per 100g. The NHS notes that a stated serving may differ from the amount you eat. | I want to know the calories in the amount I will actually have, especially if I am comparing a small bag with a sharing pack. |
| Salt and fat | Compare salt and fat separately from kcal, using the same serving basis. Walkers UK lists 0.17g salt and 132 kcal per 25g pack for Lightly Salted, versus 0.19g salt and 96 kcal per 22g pack for Oven Baked Sea Salt. | If salt is my main concern, I will check the salt figure rather than assume a lightly salted bag is also the lower-calorie choice. |
| Ingredients and allergens | Read the current ingredients, allergen statement and dietary information for the exact flavour. Walkers UK lists milk ingredients in Oven Baked Cheese & Onion. | I need a flavour that meets my dietary requirements, not just a general claim about a brand or range. |
| Sharing packs | Check how many servings the bag contains and the weight of each serving. Tyrrells lists five 30g servings in its 150g Lightly Sea Salted bag, at 156 kcal per stated serving. | For a bag kept in my room, I want to decide whether I will eat one serving or more before comparing it with a single bag. |
Easy mistakes to avoid
-
Assuming a smaller bag is lower in calories per gram
A 22g bag can have fewer calories than a larger bag partly because it contains less food. Pack totals answer a different question from per-100g figures.
Use kcal per pack for the snack you plan to eat, and kcal per 100g to compare products on the same weight basis.
-
Reading “lightly salted” as “lower calorie”
Walkers UK lists 132 kcal per 25g pack for Lightly Salted and 96 kcal per 22g pack for Oven Baked Sea Salt. The packs also differ in size.
Check salt in grams when salt matters to you, and kcal for your intended portion when calories matter.
-
Treating a sharing bag as one serving
Tyrrells describes its 150g Lightly Sea Salted bag as five 30g servings. Its 156 kcal figure applies to one stated serving, not the whole bag.
If you want a defined amount, choose an individual bag or measure a serving from the larger one.
-
Assuming every flavour has the same ingredients
Walkers UK lists milk ingredients in Oven Baked Cheese & Onion, while its Sea Salt product carries may-contain allergen warnings.
Read the current label on the exact pack, particularly when an ingredient or allergen affects whether you can eat it.
Brand and range references
These examples help distinguish pack sizes, flavours and dietary information; a brand name alone does not establish the calories or ingredients of every product in its range.
Walkers
Its Oven Baked single-flavour packs and conventional Lightly Salted pack illustrate why calories and salt need separate comparisons.
- Walkers UK lists 96 kcal per 22g pack for Oven Baked Sea Salt and Cheese & Onion.
- Walkers UK lists 132 kcal per 25g pack for Lightly Salted; check allergens by flavour.
Seabrook
Its labelled individual bags provide conventional potato-crisp examples at different pack weights.
- Seabrook Crisps lists 126 kcal per 25g bag for Canadian Ham Flavour and 164 kcal per 31.8g bag for Sea Salted.
- Check dietary and allergen information for the flavour you choose; the Sea Salted product is listed as suitable for vegetarians and vegans and as gluten-free.
Tyrrells
Lightly Sea Salted comes in both a single pack and a sharing format, so the stated serving matters.
- Tyrrells lists 208 kcal for its 40g pack and 156 kcal per 30g serving from its 150g bag.
- The 150g bag contains five stated servings; do not compare one serving with a whole single pack without checking the weights.
KETTLE Chips
Lightly Salted is a hand-cooked option with product-specific dietary information.
- KETTLE Chips describes this product as gluten-free and suitable for vegans and vegetarians.
- Its listed 516 kcal per 100g is not a per-bag figure; check the serving size before comparing it with an individual pack.
Pipers
Pipers describes a range built around potatoes and varied flavourings.
- The range offers flavours to consider if flavour is a deciding factor.
- Check the nutrition label and pack weight of the particular flavour before choosing it for a calorie-based comparison.
REAL Hand Cooked Crisps
REAL describes its range as vegetarian and gluten-free.
- The brand’s stated range information can help narrow a dietary search.
- Check the exact pack for allergens, ingredients and calories rather than assuming a dietary statement also means fewer calories.
Joybuy product options
These options include portioned baked potato snacks, a potato-based variety pack and a corn-based alternative. For a potato-crisp choice, check the product type as well as the size of each bag.

Walkers Oven Baked Variety Pack, 6 x 22g
Six individual bags offer a defined pack size for stocking a new room. Joybuy lists Sea Salt, Cheese & Onion and Salt & Malt Vinegar in the variety pack; Walkers UK lists 96 kcal per 22g for the Sea Salt and Cheese & Onion products separately. Check each flavour’s pack for its own nutrition and allergens.

Walkers Oven Baked Cheese & Onion, 6 x 22g
This single-flavour multipack keeps each bag to 22g. Walkers UK lists 96 kcal per 22g Cheese & Onion pack and milk-derived ingredients; check the current pack for the full allergen statement.

Smiths Frazzles Crispy Bacon Flavour, 6 x 20g
The six individual 20g bags may suit someone looking for a portioned savoury snack. Frazzles are corn-based rather than potato crisps, so choose them as an alternative to the main potato-crisp options. Check the pack for ingredients and allergens.

Hula Hoops Variety Multipack, 12 x 24g
Twelve individual 24g bags provide a defined size for each snack and a choice of flavours. Check the nutrition and allergen information for the particular bag you intend to eat; the multipack format alone does not establish its calorie content.
Questions about choosing crisps
Which crisps offer a smaller-calorie single snack?
Walkers UK lists 96 kcal per 22g pack for Oven Baked Sea Salt and Cheese & Onion. That is below the pack totals listed by Seabrook Crisps for its 25g Canadian Ham Flavour bag at 126 kcal and by Tyrrells for its 40g Lightly Sea Salted bag at 208 kcal. The weights differ, so also compare kcal per 100g if you want a same-weight comparison.
Should I compare calories per pack or per 100g?
Use the pack or serving figure to judge the amount you expect to eat, and the per-100g figure to compare crisps at the same weight. The NHS notes that a manufacturer’s stated portion may differ from yours, which matters particularly with sharing bags.
Does “lightly salted” mean fewer calories?
No: the description concerns salt, not the calorie count. Walkers UK lists 0.17g salt and 132 kcal per 25g pack for Lightly Salted, compared with 0.19g salt and 96 kcal per 22g pack for Oven Baked Sea Salt. Check the figure for the nutrient that matters to your choice and account for the different pack weights.
Can I rely on a brand-wide dietary description for every flavour?
Check the exact flavour’s current ingredients and allergen statement instead. Walkers UK lists milk ingredients in Oven Baked Cheese & Onion and may-contain warnings for Oven Baked Sea Salt, showing why the individual pack matters.
