What should you check?
Decide whether you want a portion of crisps or something more substantial, then compare the exact pack you would eat. Calories per 100g help compare different bag sizes; calories per pack tell you about the portion.
A portioned baked crisp
Choose when: A small pack and lower declared calorie density matter more to you than conventional crisp texture.
Trade-off: The compared Walkers baked product is a crisp snack, not a substitute for a more substantial supper.
Conventional potato crisps
Choose when: The texture or a particular flavour matters more to you, and you can choose the portion you intend to eat.
Trade-off: The conventional products compared here have higher declared kcal per 100g than Walkers Oven Baked Sea Salt; a small bag does not change that per-100g figure.
Another light snack
Choose when: You are hungry and want food that contributes more than savoury crunch.
Trade-off: It may not satisfy a specific craving for crisps; keep the amount appropriate to what you want to eat close to bedtime.

What to check |
Your needs |
| Calories and portion |
Read kcal per pack or serving for the amount you plan to eat. Use kcal per 100g to compare different bag sizes; Walkers UK lists 438 kcal per 100g and 96 kcal per 22g pack for Oven Baked Sea Salt. |
I want a modest portion of crisps, so the figure for the amount I will actually eat matters more than the bag’s appearance. |
| Salt |
Check salt per portion as well as per 100g on the exact flavour. NHS guidance says adults should have no more than 6g of salt a day in total, including salt already in food. |
Calories are not my only consideration; I also want to account for the salt in this snack alongside other food I eat. |
| Reason for eating |
Ask whether a small crisp portion answers a craving for crunch or whether you want a more substantial light snack. Oxford Health NHS Foundation Trust cautions that a heavy meal close to bed can interrupt sleep. |
If I am genuinely hungry, crisps alone may not be the sort of snack I am looking for. |
| Dietary suitability |
Read the ingredients, allergen declaration and any vegetarian, vegan or gluten-free statement on the exact pack. These labels do not tell you its calorie content. |
I need the product to meet my dietary requirements, and I want to check that separately from its kcal figures. |
Brand references
These figures refer to named products, not every flavour or pack a brand makes. Compare the nutrition panel on the exact product you are considering.
Walkers
Walkers UK lists Oven Baked Sea Salt at 438 kcal per 100g and 96 kcal per 22g pack.
- The stated pack size makes its per-pack calorie figure straightforward to compare with a planned snack portion.
- Use the nutrition and ingredient details for this exact baked product rather than applying its figures to other Walkers crisps.
Tyrrells
Tyrrells lists potato crisps, Furrows and lentil crisps as separate parts of its range.
- The range offers different crisp styles to consider if texture is part of your choice.
- Check the nutrition panel for the particular potato-crisp flavour and bag size; a figure for lentil crisps does not describe its potato crisps.
KETTLE Chips
KETTLE Chips lists Sea Salt and Crushed Black Peppercorns at 505 kcal and 1.3g salt per 100g.
- Both declared figures can be compared with other named flavours on a per-100g basis.

Seabrook
Seabrook Crisps lists Sea Salted at 516 kcal and 1.3g salt per 100g.

UK retailer Snackline Direct lists Pipers Anglesey Sea Salt at 532 kcal and 0.94g salt per 100g.
- The listed per-100g figures give a basis for comparing this flavour with the other named products.

Questions about late-night crisps
Which calorie figures should I compare when choosing crisps?
Use kcal per pack or serving for the amount you plan to eat, then kcal per 100g to compare products sold in different bag sizes. Walkers UK lists Oven Baked Sea Salt at 96 kcal per 22g pack and 438 kcal per 100g; the conventional products named in this article have different pack sizes.
Do baked crisps make a suitable late-night supper?
A portion of baked crisps may answer a craving for crunch, but choose something else if you want a more substantial snack. Oxford Health NHS Foundation Trust notes that a light snack can be useful when an empty stomach is distracting, while a heavy meal close to bed can interrupt sleep.
Should I check salt as well as calories?
Yes, if salt matters to your choice, check it for the exact portion you intend to eat. NHS guidance says adults should have no more than 6g of salt a day in total, including salt already in packaged food.
Can traffic-light labels help me compare crisps?
Where present, traffic-light colours give a quick indication of the listed nutrients, but also read the calorie figure and portion size. Food Standards Agency guidance published on GOV.UK for Northern Ireland explains that green, amber and red indicate low, medium and high levels of nutrients shown on the label.
Are vegetarian or gluten-free crisps lower in calories?
Those labels describe dietary suitability, not calorie content. For example, KETTLE Chips lists its Sea Salt and Crushed Black Peppercorns product at 505 kcal per 100g, and Seabrook Crisps lists Sea Salted at 516 kcal per 100g; check the exact pack for both dietary claims and nutrition values.
