Packed-lunch portion planners
If you pack one individual bag, its stated calories, weight and salt are more useful for planning that portion than an impression that the range is lighter.
Who is choosing?
The useful comparison depends on what matters alongside the crisp portion: pack size, crisp style or the ingredients in the exact flavour.
Shoppers comparing crisp styles
Baked, lentil, hand-cooked and crinkle-cut products come in different portions. Compare the particular bags rather than assuming a cooking style or reduced-fat statement answers the calorie question.
Lunch packers checking allergens
If an allergy or intolerance is relevant, check the ingredients and precautionary allergen wording on the actual flavour and pack, especially when changing product lines.
What should you compare?
Start with the portion you will eat. Then compare packs on a common per-100g basis where their weights differ, without losing sight of salt or ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bag | Read kcal and weight for the individual bag, not just the multipack. Walkers UK lists 78 kcal per 18g Ready Salted French Fries bag, 86 kcal per 16g Quavers Cheese bag and 96 kcal per 22g Oven Baked Sea Salt bag. | For a lunch accompaniment, I want to know the calories in the one bag I intend to pack and eat. |
| Pack size | Compare bag weight alongside kcal per bag and kcal per 100g. NHS food-label guidance explains that nutrition information is given per 100g and sometimes per portion; those figures answer different questions. | A smaller bag may fit my planned crisp portion, but I also want a like-for-like comparison when the bag sizes differ. |
| Salt | Check salt per bag and per 100g. Walkers UK lists 0.45g salt per 18g Ready Salted French Fries bag, or 2.50g per 100g; the NHS describes more than 1.5g salt per 100g as high. | I want to consider the bag’s salt as well as its calories alongside the rest of lunch. |
| Fat claims | Read the stated comparator and the kcal for your serving separately. Walkers UK compares Oven Baked Sea Salt’s fat content with regular potato crisps; Tyrrells lists 141 kcal per 30g serving of Sour Cream & Onion lentil crisps. | If I choose baked or lentil crisps for their style or ingredients, I still want to check the calories in the portion I will eat. |
| Ingredients | Check the exact flavour’s ingredients and precautionary allergen statement on the pack. Walkers UK lists milk, soya, barley and wheat for Quavers Cheese; allergen wording differs between products. | When packing lunch for someone with an allergy or intolerance, I need the information for that particular bag, not another flavour in the range. |
Common buying mistakes
-
Reading “less fat” as “fewer calories”
Walkers UK says its Oven Baked Sea Salt product has 50% less fat than regular potato crisps. That is a fat comparison; the specified 22g bag lists 96 kcal.
Use the kcal for the bag you intend to eat to compare crisp portions, and consider fat as a separate figure.
-
Using only the per-100g calorie figure
Per-100g figures help compare products at the same weight, but the examined individual bags weigh 16g, 18g and 22g. Their per-bag figures describe different-sized portions.
Read the bag weight, kcal per bag and kcal per 100g together before choosing a lunch portion.
-
Assuming fewer calories means less salt
Walkers UK lists 78 kcal and 0.45g salt for its 18g Ready Salted French Fries bag. It lists 2.50g salt per 100g for that product, above the NHS threshold of 1.5g per 100g for a high-salt food.
Compare salt for the bag as well as calories, particularly if other items in the lunch also contain salt.
-
Relying on another flavour’s allergen details
The examined Quavers Cheese and Oven Baked Sea Salt products have different allergen statements. A familiar brand name does not identify the ingredients of every flavour.
If allergens matter, read the ingredients and precautionary wording on the particular pack before it is eaten.
Brand and product-line references
These examples show why the exact product and pack size matter more than a brand-wide description. They do not establish that every flavour in a range has the same nutrition values.
Walkers
The examined range includes individual bags of different weights and crisp styles.
- Walkers UK lists 78 kcal per 18g Ready Salted French Fries bag, 86 kcal per 16g Quavers Cheese bag and 96 kcal per 22g Oven Baked Sea Salt bag.
- Salt and allergen details differ between these products; the figures do not describe every Walkers crisp.
Tyrrells
Its examined Sour Cream & Onion lentil crisps provide an alternative base ingredient to potato crisps.
- Tyrrells lists 141 kcal, 3.9g protein and 0.60g salt per 30g serving.
- The brand’s reduced-fat comparison refers to a reviewed set of standard potato crisps from March 2021; it is not a comparison of calories in these individual bags.
Kettle Chips
Lightly Salted is an examined hand-cooked potato-crisp option.
- Kettle Chips lists 516 kcal and 0.7g salt per 100g for Lightly Salted.
- “Lightly Salted” does not describe its calorie content. Check the weight of the pack you plan to eat.
Seabrook
Sea Salted is an examined crinkle-cut potato crisp with nutrition stated per bag.
- Seabrook lists 164 kcal and 0.4g salt per 31.8g Sea Salted bag.
- Those values apply to the named flavour and bag size, not the whole range.
McCoy's
McCoy's lists ridged crisps among its range for shoppers who prefer that style.
- To compare a particular bag with the portions above, check its stated pack weight and kcal.
Real Crisps
Sea Salt is an examined hand-cooked potato crisp offered in a 35g bag size.
- REAL Hand Cooked Crisps lists 515 kcal per 100g for Sea Salt.
- Use the nutrition information for the particular bag when planning a lunch portion; the per-100g figure is not a per-bag value.
Joybuy options for packed lunches
These multipacks contain individual bags that can be packed with lunch. Compare the nutrition and allergen information for the exact flavour you choose; figures for a different flavour or product line should not be carried across.

Questions about crisp portions
Should I compare calories per bag or per 100g?
Use kcal per bag for the portion you intend to eat, and kcal per 100g to compare products at the same weight. Check the bag weight too: a smaller bag can have fewer total calories without being less energy-dense.
Does “less fat” mean a bag has fewer calories?
Not necessarily. Walkers UK’s “50% less fat” statement for Oven Baked Sea Salt compares fat with regular potato crisps; its specified 22g bag lists 96 kcal. Compare per-bag kcal directly when calories are your deciding factor.
Can a small bag of crisps stand in for lunch?
A bag’s calorie figure describes that crisp portion, not an entire lunch. Plan what else you are taking separately rather than using the crisp pack as a measure of the whole meal.
What if someone eating the lunch has a food allergy?
Check the ingredients and precautionary allergen wording on the actual pack for the specific flavour. For example, Walkers UK lists milk, soya, barley and wheat for Quavers Cheese; do not assume another product in the range has the same statement.
Does a “low calorie” search result establish a nutrition claim?
No. Search wording is not a substitute for the product’s stated kcal and portion size. GOV.UK says businesses making nutrition claims must follow specific rules, so assess the exact pack information rather than treating a search phrase as a product claim.
