Late-night snackers comparing calories
If you plan to eat one packet, its stated weight and calories help you compare the portion you would actually open. Use calories per 100g as well when packet sizes differ.
Who is this choice for?
Buyers who prefer conventional potato crisps
If you want a traditional hand-cooked crisp, compare its nutrition panel with baked options at the same weight rather than relying on a flavour name or pack description.
Buyers open to a different snack
A pre-portioned lentil snack may be worth considering if potato content is not essential. Check its own pack and nutrition information rather than treating it as the same product as a potato crisp.
What should you compare?
Start with the portion you expect to eat, then compare calories per 100g so different pack sizes do not obscure the difference between products.
| Priority | What to check | Your needs |
|---|---|---|
| Calories | Compare kcal per 100g at an equal weight, then check kcal for the portion you intend to eat. Walkers UK lists Oven Baked Sea Salt at 438 kcal per 100g and 96 kcal per typical 22g pack. | I want to know both how this crisp compares with others and what one packet would contain. |
| Portion format | Check the packet weight and whether the nutrition panel describes the whole packet or a smaller serving. Decide how much to take from a sharing bag before opening it. | A single packet would make my planned late-night portion simpler; with a larger bag, I would measure one out. |
| Snack type | Check whether the product is a potato crisp or a lentil-based alternative. Walkers Oven Baked Sea Salt uses potato flakes and starch, while the Seabrook and Tyrrells lentil products are not potato crisps. | Potato content matters to me, or I am happy to consider a different type of savoury snack. |
| Ingredients and labels | Read the exact flavour’s ingredients, allergen statement, salt declaration and pack weight. A “lightly salted” name or a vegan or gluten-free declaration does not state its calorie content. | I need the flavour I choose to meet my ingredient or allergen requirements, alongside the portion and calorie figure. |
What can make comparisons misleading?
-
Choosing by the smallest packet figure alone
A smaller packet can contain fewer calories because it contains less food, even when its calories per 100g are higher.
Compare products per 100g, then check the calories in the portion you plan to eat.
-
Reading “lightly salted” as “lower calorie”
KETTLE Chips lists Lightly Salted at 516 kcal per 100g, while Walkers UK lists Oven Baked Sea Salt at 438 kcal per 100g. Their names do not establish that comparison.
Use the nutrition panels for the exact products, and check salt separately if it matters to your choice.
-
Treating lentil snacks as potato crisps
A small lentil-snack packet can have a useful stated portion size, but it is a different product from a potato crisp.
Keep the comparison within potato-based products if that is what you want; otherwise compare each alternative’s pack size and nutrition on its own terms.
Which brands are relevant?
Walkers
The Oven Baked range offers a potato-based option for comparing with conventional crisps.
- Walkers UK lists Oven Baked Sea Salt at 96 kcal per typical 22g pack and 438 kcal per 100g.
- This product uses potato flakes and starch rather than sliced potato. Check the exact pack’s allergen statement.
Tyrrells
Its lentil crisps are an alternative for buyers who do not require a potato crisp.
- Tyrrells lists 140–141 kcal per 30g serving for its Sweet Chilli & Red Pepper and Sour Cream & Onion lentil crisps.
- Those figures describe lentil crisps, not the brand’s potato crisps.
KETTLE Chips
Lightly Salted is a conventional hand-cooked potato crisp to compare by its nutrition panel.
- KETTLE Chips lists 0.7g salt per 100g for Lightly Salted.
- The same product is listed at 516 kcal per 100g; its name alone does not indicate a lower-calorie crisp.
Seabrook
Its baked red-lentil hoops provide a separately portioned alternative to potato crisps.
- Seabrook lists Sour Cream & Chive Lentil Hoops at 75 kcal per 17g bag.
- The hoops are lentil-based, so the small-bag figure should not be used as a like-for-like potato-crisp comparison.
Pipers
Anglesey Sea Salt is a conventional potato-crisp example for buyers comparing salted varieties.
- Pipers lists Anglesey Sea Salt at 532 kcal and 0.94g salt per 100g.
- Compare its stated portion weight with a smaller packet before judging what you would eat in one sitting.
REAL Hand Cooked Crisps
Sea Salt & Black Pepper is another conventional potato-crisp example for a per-100g comparison.
- REAL Hand Cooked Crisps lists this flavour at 495 kcal per 100g.
- That figure belongs to Sea Salt & Black Pepper; check other flavours individually.
Joybuy crisp options
These options include oven-baked multipacks, a PopChips bag, a ridge-cut multipack and a larger sharing bag. Compare the exact flavour’s label and the portion you intend to eat; the Walkers Oven Baked Sea Salt figures above do not automatically apply to other varieties.

Walkers Oven Baked Variety Pack Crisps, 6 × 22g
The 6 × 22g format lets you choose one packet for a late-night snack. Check each included flavour’s nutrition and allergen label rather than applying the separate Sea Salt product’s figures to the whole variety pack.

Walkers Oven Baked Cheese & Onion Crisps, 6 × 22g
Each packet in this 6 × 22g multipack has a stated weight, which makes it straightforward to check the calories for one packet. Read the Cheese & Onion nutrition and allergen label rather than borrowing figures from Oven Baked Sea Salt.

PopChips Sour Cream & Onion, 85g
For an 85g bag, decide how much you intend to eat before using any per-serving calorie figure. Check the Sour Cream & Onion label for the stated serving size and allergens.

McCoys Ridge Cut Mighty Meaty Crisps, 6 × 25g
The 6 × 25g ridge-cut multipack offers individual packets if you prefer a conventional crisp format. Compare this flavour’s calories per packet and per 100g with other options, and check its allergen label.

Sensations Thai Sweet Chilli Crisps, 150g
With a 150g bag, check the stated serving size if you want less than the whole pack as a midnight snack. Use the Thai Sweet Chilli label for its calorie and allergen information.
Common questions
Are baked potato crisps always lower in calories?
No conclusion about every baked crisp follows from its cooking method. Walkers UK lists Oven Baked Sea Salt at 96 kcal per typical 22g pack and 438 kcal per 100g; check the nutrition panel and pack size of any other product you are considering.
Should I compare calories per bag or per 100g?
Use both: calories per 100g allow a comparison across different pack sizes, while calories for the amount you plan to eat address your actual portion. Check whether a bag contains more than the serving described on its label.
Does “lightly salted” mean a crisp is lower in calories?
No. KETTLE Chips lists Lightly Salted at 516 kcal and 0.7g salt per 100g. Check calorie and salt declarations separately for the exact flavour instead of using its name as a substitute for either figure.
