Choose a 25g individual bag if you want a smaller, defined afternoon portion; consider a 35g–45g bag when you deliberately want more crisps. Pack weight alone does not tell you the nutrition or allergen details: Walkers UK lists 128 kcal for its 25g Salt & Vinegar bag, Tesco lists 174 kcal for a 35g REAL Roast Ox bag, and ASDA lists 238 kcal for a 45g McCoy's Salt & Malt Vinegar bag. Check the figures and ingredients for the exact flavour you choose.
If you want a short afternoon break rather than a larger bag, start by comparing individual 25g packs with 35g–45g options. Read the nutrition per bag as well as its weight: Walkers UK lists 128 kcal for a 25g Salt & Vinegar bag, while ASDA lists 238 kcal for a 45g McCoy's Salt & Malt Vinegar bag.
If the hand-cooked style matters more to you than choosing the smallest bag, Tyrrells lists a 40g Lightly Sea Salted format, while Tesco lists REAL Roast Ox in a 35g pack. Compare the individual pack sizes before treating either as equivalent to a 25g multipack bag.
Choose by the exact flavour and its current ingredients, suitability statements and precautionary allergen wording. A claim attached to one recipe should not be assumed to cover every crisp from the same brand.
Decide how much you want in one bag, then compare the exact flavour's per-pack nutrition and ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Bag size | Read the weight of each individual bag, not just the multipack weight. Compare nutrition for the whole bag if that is the amount you plan to eat. | I want a small, defined afternoon portion, so a 25g bag is my starting point. If I want more crisps at once, I can compare 35g, 40g and 45g packs instead. |
| Flavour and salt | Check salt for the exact flavour and serving size. If a pack makes a reduced-salt claim, read both its stated comparison and its own salt figure. | Flavour matters to me, but I do not want to assume two recipes have the same salt content because their bags weigh the same. |
| Allergens | Read the current ingredient list and any “may contain” statement. Check the particular recipe for relevant ingredients, including milk or cereals containing gluten. | Where an ingredient or precautionary warning matters to me, I need the declaration for the bag I am buying—not another flavour's label. |
| Dietary labels | Look for vegan, vegetarian or gluten-free wording on the exact product. Check the ingredients alongside the suitability statement. | I may want a particular dietary label or a short ingredient list; neither tells me the nutrition of a different recipe. |
| Vegetable crisps | Compare per-100g figures on like-for-like products, then check the weight of the bag you will eat. KETTLE Chips lists 32.9g fat, 21.3g sugars and 1.0g salt per 100g for its Lightly Salted Veg Chips. | I might choose vegetable crisps for their ingredients, but I will compare the label rather than assume “veg” means a lower figure. |
A 25g multipack bag and a 45g grab bag contain different amounts of crisps. Their flavour-specific nutrition can differ too.
Choose the individual bag weight that fits the occasion, then read nutrition for that whole bag.
Vegetable ingredients do not establish how a finished crisp compares with a potato crisp. KETTLE Chips lists 32.9g fat, 21.3g sugars and 1.0g salt per 100g for its Lightly Salted Veg Chips.
Compare the same nutrients on a per-100g basis, then check the bag size for the amount you plan to eat.
Ingredients and precautionary warnings can differ between crisp recipes, including flavours from one brand.
Read the current pack's ingredients and “may contain” wording before choosing a flavour when an allergen is relevant to you.
These examples illustrate pack formats and label details to compare; a statement about one flavour does not describe every product from its brand.
Individual 25g bags offer a defined multipack portion for an afternoon snack.
Tyrrells lists Lightly Sea Salted hand-cooked crisps in a 40g format.
The Lightly Salted potato-crisp line provides an example with specific dietary suitability statements.
A classic variety-box format offers individually packed 25g bags and a choice of flavours.
Ridge-cut crisps appear in both smaller multipack bags and larger grab-bag formats.
The 35g Roast Ox pack sits between the 25g and 40g–45g examples by bag weight.
These McCoy's and Walkers multipacks contain individual 25g bags for separate afternoon snack occasions. They represent the smaller-portion route, not the 35g–45g single-bag options discussed above.

Six individual 25g bags provide a defined portion for separate snack occasions. This is a multipack rather than one larger grab bag; check the current flavour's ingredients and allergen warning if relevant.

The 6 × 25g format suits choosing one individual bag at a time. Check the Cheddar & Onion pack's ingredients and allergen declaration rather than relying on another McCoy's flavour.

Six 25g bags let you choose one smaller portion for an afternoon break. Read this Roast Chicken recipe's own nutrition and precautionary allergen wording; figures for other Walkers flavours do not describe it.

This multipack contains six individual 25g bags for separate snacks. Check the Prawn Cocktail pack's ingredients and allergen information if either affects your choice.

Six individual 25g bags offer a smaller portion for each snack occasion. The multipack's flavours call for a pack-by-pack ingredient and allergen check; compare nutrition for a 25g bag when deciding how it fits your afternoon snack.
Start with an individual 25g bag if a defined, smaller portion is what you want. Bag size is not a substitute for reading the label: Walkers UK lists 128 kcal for its 25g Salt & Vinegar bag, while Tesco lists 174 kcal for a 35g REAL Roast Ox bag and ASDA lists 238 kcal for a 45g McCoy's Salt & Malt Vinegar bag.
No such conclusion follows from the vegetable ingredients alone. KETTLE Chips lists 32.9g fat, 21.3g sugars and 1.0g salt per 100g for its Lightly Salted Veg Chips; compare the exact products' per-100g labels and the sizes of the bags.
Check the statement on the exact product rather than applying it across a brand. KETTLE Chips labels its Lightly Salted product gluten-free and suitable for vegans and vegetarians; that statement does not establish the status of every KETTLE flavour.
Read both the current ingredient list and any precautionary “may contain” wording for the particular flavour. If milk, cereals containing gluten, soya, mustard or celery matter to you, do not substitute another flavour's declaration for the bag you intend to eat.
