People choosing a single desk snack
If you expect to finish one bag at a break, its kcal per pack tells you more about that portion than a comparison of bag sizes alone. Use kcal per 100g as a second check when choosing between products.
Who is this for?
Office buyers sharing snacks
Individual packs are convenient to set out for colleagues, but dietary suitability depends on the exact product. Check each flavour’s ingredients, allergen warnings and any stated vegan or gluten-free suitability.
Shoppers considering baked or lentil crisps
If a reduced-fat claim draws your attention, compare calories and salt as well. Tyrrells lists 140–141 kcal per 30g serving for the lentil flavours in its nutrition information, despite its range-level reduced-fat claim.
What should you compare?
Start with the amount you are likely to eat at one break. Then compare products on the same per-100g basis and check the details that matter to the people sharing them.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per pack | Read the kcal figure for the sealed pack or stated serving. Check whether the serving is the whole bag. Walkers UK lists 96 kcal for a 22g Oven Baked Sea Salt pack. | I expect to eat one bag at my desk, so I want its calorie figure to describe the portion I will actually have. |
| Bag size and calorie density | Compare bag weights and kcal per 100g as well as kcal per bag. Seabrook lists 126 kcal per 25g LEA & PERRINS bag and 164 kcal per 31.8g Sea Salted bag; the bags contain different amounts. | A smaller bag may suit one break, but I also want to know how two crisps compare at the same weight. |
| Salt and fat | Read salt per pack or serving and fat per 100g for the exact flavour. Compare these figures alongside calories rather than treating a baked or reduced-fat description as a complete nutrition comparison. | Calories are my starting point, but I do not want a lower-calorie pack to make me overlook its salt content. |
| Dietary suitability | Check the exact pack for ingredients, allergen and may-contain statements, and any vegan or gluten-free claim. A claim about one flavour does not establish suitability across a range. | When I buy for colleagues, I need each person to be able to check whether a particular pack meets their requirements. |

Comparing pack calories without checking weight
Seabrook lists 126 kcal for a 25g LEA & PERRINS bag and 164 kcal for a 31.8g Sea Salted bag. Part of the difference is that the Sea Salted bag contains more crisps.
Use kcal per pack for the snack you plan to eat, then kcal per 100g for a like-for-like comparison.

Reading “less fat” as “fewer calories”
Tyrrells states that its Lentil Crisps have 30% less fat than standard potato crisps on average. Its listed Sweet Chilli & Red Pepper and Sour Cream & Onion flavours still provide 140 and 141 kcal per 30g serving respectively.
Check the exact flavour’s kcal per serving, kcal per 100g and salt rather than relying on the fat claim alone.

Assuming a dietary claim covers every allergen
KETTLE describes its Lightly Salted crisps as gluten-free and suitable for vegans and vegetarians. Walkers Oven Baked Sea Salt carries a may-contain allergen statement. Neither example establishes the allergen details of another flavour.
For a colleague with an allergy or a medically required diet, check the ingredients and allergen information on the exact physical pack before sharing it.

Questions about choosing crisps
Should I compare calories per pack or per 100g?
Use kcal per pack if you expect to eat the whole bag, and kcal per 100g to compare products of different weights. Walkers UK lists 96 kcal per 22g pack and 438 kcal per 100g for Oven Baked Sea Salt; Seabrook lists 164 kcal per 31.8g bag and 516 kcal per 100g for Sea Salted.
Do crisps described as lower in fat always have fewer calories?
No: a fat comparison does not tell you the calories in the portion. Tyrrells states that its Lentil Crisps have 30% less fat than standard potato crisps on average, while its listed flavours provide 140–141 kcal per 30g serving. Check the calorie figure and serving weight for the flavour you choose.
Can I use a vegan or gluten-free claim to decide what to share at work?
Use the claim for the exact product as a starting point, but check its full ingredients and allergen information for each colleague’s requirements. KETTLE describes Lightly Salted as gluten-free and suitable for vegans and vegetarians, while Walkers Oven Baked Sea Salt carries a may-contain allergen statement.
