For a lower-calorie potato-crisp snack on a road trip, compare both calories per 100g and calories in the bag you expect to eat. Walkers lists 96 kcal per 22g pack and 438 kcal per 100g for Oven Baked Sea Salt; the KETTLE Lightly Salted and Seabrook Sea Salted potato crisps considered here each list 516 kcal per 100g. A smaller bag helps you judge the portion, while flavour names such as ‘lightly salted’ do not establish a calorie difference.
A single-serve pack lets you compare the calories in the snack you plan to eat. Walkers lists 96 kcal for its 22g Oven Baked Sea Salt pack; Seabrook lists 164 kcal for its larger, 31.8g Sea Salted bag. Check per-100g figures as well, so pack size does not obscure the product difference.
If reducing fat matters more than choosing a potato crisp, lentil crisps are another product type to consider. Tyrrells describes its lentil crisps as having 30% less fat than standard potato crisps on its own comparison basis; the listed flavours still contain 140–141 kcal per 30g serving.
Compare the salt stated for the pack or serving alongside the rest of the food you intend to take. The NHS advises adults to have no more than 6g of salt a day. Check the exact flavour’s ingredient, allergen and suitability information rather than relying on a range-wide description.
Start with the bag you are likely to eat, then use the per-100g panel to compare different products on the same basis.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and pack size | Read kcal per 100g and per whole bag. Walkers Oven Baked Sea Salt is 438 kcal per 100g and 96 kcal per 22g pack; Seabrook Sea Salted is 516 kcal per 100g and 164 kcal per 31.8g bag, according to the brands’ product information. | I want to know the calories in the bag I will actually eat, without treating differently sized bags as equivalent. |
| Type of crisp | Compare the exact product’s nutrition panel, not its cooking method or flavour name alone. KETTLE lists 516 kcal per 100g for Lightly Salted potato crisps; Tyrrells lists 140–141 kcal per 30g serving for its lentil-crisp flavours. | I may switch from potato crisps to lentil crisps, but only after comparing the serving size and calories. |
| Salt | Find the salt amount for the serving or whole bag and consider other food on the journey. The NHS advises adults to have no more than 6g of salt a day. | If I am keeping track of salt, the crisp bag needs to be considered alongside my other snacks and meals. |
| Ingredients and suitability | Read the current label for the exact flavour, including ingredients, allergens and may-contain statements. KETTLE describes its Lightly Salted potato crisps as gluten-free and suitable for vegans and vegetarians; that description does not establish the status of other flavours. | When an ingredient or dietary requirement matters, I need the information for the particular bag I am buying. |
Salt-related wording does not tell you the calorie density. KETTLE lists 516 kcal per 100g for Lightly Salted potato crisps, compared with Walkers’ 438 kcal per 100g for Oven Baked Sea Salt.
Compare kcal on the exact packs using the same per-100g basis, then check the amount in each bag.
Walkers’ 22g Oven Baked Sea Salt pack contains 96 kcal, while Seabrook’s 31.8g Sea Salted bag contains 164 kcal. Those bags differ in both weight and calories per 100g.
Use per-100g values to compare the crisps, and per-bag values to judge the portion you intend to eat.
Tyrrells lists 140–141 kcal per 30g serving for its lentil crisps, despite its lower-fat comparison with standard potato crisps. KETTLE lists 514 kcal per 100g for Lightly Salted vegetable chips.
Treat the base ingredient as a choice of product type; check calories and serving size separately.
Salt and ingredient information varies by product and flavour. A broad description of a crisp range may not answer a question about the bag in your hand.
Read the selected pack’s salt, ingredient and allergen information before you set off, particularly where an allergy or specific dietary restriction applies.
These examples show why the exact product and pack matter more than a brand name when comparing road-trip snacks.

Six 22g bags make it straightforward to choose one bag for a stop on the journey. The variety pack includes Sea Salt, Cheese & Onion, and Salt & Malt Vinegar; check the chosen flavour’s nutrition and allergen label rather than applying the Sea Salt figures to every bag.

Five 17g bags offer another small-pack option for the journey. Compare the exact bag’s calories and ingredients with the other crisps you are considering, especially if you have an allergen-related requirement.
Use kcal per 100g to compare the products, then kcal per whole bag for the portion you expect to eat. Walkers lists 438 kcal per 100g and 96 kcal per 22g pack for Oven Baked Sea Salt; Seabrook lists 516 kcal per 100g and 164 kcal per 31.8g bag for Sea Salted.
No calorie difference follows from that wording alone. KETTLE Lightly Salted potato crisps list 516 kcal per 100g, while Tyrrells Lightly Sea Salted potato crisps list 519 kcal per 100g. Read the nutrition panel for the exact product.
Not automatically. Tyrrells lists 140–141 kcal per 30g serving for its lentil-crisp flavours and describes them as 30% lower in fat than standard potato crisps on its own comparison basis. They are not potato crisps, so compare calories, salt and portion size before switching.
Check the salt stated for the bag alongside the rest of the day’s food. The NHS advises adults to have no more than 6g of salt a day, including salt already present in packaged food.
