Day-trippers packing a single snack
For travel, a beach day or an attraction visit, the calories in the bag you will actually eat may be more useful than a per-100g figure alone. Check the bag weight as well as its calorie count.
Who is choosing these snacks?
Parents packing snacks for an outing
Individual bags make portions visible when packing. The NHS advises checking packaging and nutrition labels for packaged snacks; read the ingredients and allergen information for each flavour too.
Buyers with dietary requirements
A calorie figure cannot establish whether a snack meets an allergy-related requirement or a dietary preference. Check the exact product and flavour, including any precautionary allergen wording, rather than relying on the brand name.
What should you compare?
Choose the portion you are likely to eat, then compare its calories, salt and ingredients. Use per-100g figures when you need a like-for-like comparison between different bag sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bag | Read kcal alongside the stated bag weight. Walkers lists 86 kcal per 16g Quavers Cheese pack; Seabrook lists 81 kcal per 18g Salt & Vinegar Crunchies bag. | I want to pack one bag for an outing without having to divide up a sharing pack. |
| Salt | Check salt separately from calories on the exact flavour. Seabrook lists 0.39g salt in its 18g Salt & Vinegar Crunchies bag. | A lower calorie figure matters to me, but I also want to compare the salt shown on the pack. |
| Ingredients and allergens | Read the ingredients, allergen statement and any precautionary wording for every flavour in a variety pack. Recheck the pack received. | Someone eating the snack has an allergy, intolerance or dietary preference, so the precise flavour matters. |
| Sharing-bag portions | Compare per-100g energy and the amount you plan to serve. KETTLE lists 516 kcal per 100g for Lightly Salted crisps; that figure is not the calories in an unspecified handful. | I may take a sharing bag, but I need to decide how much goes into each outing portion. |
Common buying mistakes
-
Comparing bag calories without noticing bag size
An individual bag and a sharing bag describe different amounts of food. Seabrook lists 81 kcal for an 18g Crunchies bag, while KETTLE gives 516 kcal per 100g for Lightly Salted crisps; those figures are not for equal portions.
Check the weight you expect to eat and its stated calories. Use the per-100g figures if you want to compare the products on the same weight basis.
-
Assuming fewer calories means less salt
Energy and salt are separate label entries. Seabrook Salt & Vinegar Crunchies list 81 kcal and 0.39g salt per 18g bag.
Check both entries for the exact flavour. Where traffic-light information appears, use it as a quick comparison aid and read the nutrition table for the amounts.
-
Checking only the outer name of a variety pack
Flavours within a range can have different ingredients and allergen statements. A familiar brand name does not establish what is in every inner bag.
If an allergy or intolerance is relevant, check each flavour on the pack received before it is eaten.
-
Using a reduced-fat claim as a calorie comparison
A claim about fat does not tell you which of two differently sized bags has fewer calories. Portion size still affects the amount eaten.
Compare kcal for the intended portion, then check fat and salt separately if those figures matter to your choice.
Brand and product-range references
These examples show why the exact product and pack size matter more than the brand name alone.
Walkers
Its range includes several small crisp-style packs with different weights and ingredients.
- Walkers lists 86 kcal per 16g Quavers Cheese pack, 96 kcal per 22g Oven Baked Sea Salt pack and 97 kcal per 22g Squares pack.
- Check nutrition and allergens for the particular product and flavour, especially in a variety pack.
Tyrrells
Its lentil crisps offer a different base ingredient from conventional potato crisps.
- Tyrrells states that its lentil crisps have 30% less fat than standard potato crisps on average.
- That brand comparison does not establish the calories in the portion you will eat; check the exact flavour and serving.
KETTLE Chips
Its Lightly Salted product is a conventional potato-crisp option to assess by portion size.
- KETTLE lists 516 kcal per 100g for Lightly Salted crisps.
- A per-100g figure does not specify the calories in the amount served from a sharing pack.
Seabrook
Its small Crunchies bag and Sea Salted potato-crisp bag illustrate different portion sizes within one brand.
- Seabrook lists 81 kcal and 0.39g salt per 18g Salt & Vinegar Crunchies bag.
- Its Sea Salted potato crisps list 164 kcal per 31.8g bag; do not apply the Crunchies figure across the range.
McCoy's
Its Salted crisps provide another conventional crisp to compare by weight and intended portion.
- McCoy's lists 533 kcal per 100g for its Salted flavour.
- Check the calories for the amount you plan to eat rather than treating the per-100g figure as a single-pack value.
REAL Hand Cooked Crisps
Its Sea Salt & Black Pepper product is a hand-cooked potato-crisp option.
- REAL Hand Cooked Crisps lists 495 kcal per 100g for Sea Salt & Black Pepper.
- If you are serving it from a larger bag, check the portion weight to understand the calories eaten.
Crisp-style multipacks on Joybuy
These individually bagged multipacks offer portions to consider for summer outings. Compare the calorie, salt and allergen information on the exact pack; an individual bag is not necessarily under 100 kcal.

Walkers Oven Baked Variety Pack Crisps 6 x 22g

Wheat Crunchies Crispy Bacon 6 x 20g
Six 20g bags give you individual portions rather than a sharing bag. As the product is named Wheat Crunchies, check its full ingredient and allergen label if wheat or another ingredient is relevant to the person eating it.

Roysters T-Bone Steak Multipack Crisps 6 x 21g
The six individual 21g bags offer a defined portion for an outing. If your aim is fewer than 100 kcal in one bag, check this product’s per-bag figure before choosing it; portion-controlled does not by itself mean under 100 kcal.
Questions about choosing crisps
Should I compare calories per 100g or per bag?
Start with per-bag calories if you expect to eat one whole bag, then use per-100g figures to compare products on an equal-weight basis. Seabrook lists 81 kcal per 18g Crunchies bag, while Walkers lists 96 kcal per 22g Oven Baked Sea Salt pack; the stated portions are different sizes.
Does a lower calorie figure mean less salt?
No: check salt as a separate entry on the exact pack. Seabrook lists 81 kcal and 0.39g salt per 18g Salt & Vinegar Crunchies bag. GOV.UK advises comparing calorie, fat, sugar and salt information on food labels; traffic-light labels can help where they are displayed.
How do I check a crisp multipack for allergens?
Read the ingredients, allergen statement and any precautionary wording for each flavour on the pack received. Do not assume that two flavours—or two products from the same brand—have identical ingredients.
Can a sharing bag work when I want a smaller snack portion?
Yes, if you decide how much to serve and use the label to work out what that portion represents. A per-100g figure is not the calories in an unspecified serving: KETTLE lists 516 kcal per 100g for Lightly Salted crisps, so the amount taken from the bag matters.
