Shoppers comparing calories per bag
If you expect to eat a whole bag with your afternoon tea, the stated calories for that bag matter alongside its weight.
Who these choices suit
People who prefer conventional crisps
An individual bag gives you a stated portion. Check calories per 100g as well if you want to compare its recipe with a baked option.
Shoppers checking ingredients or dietary suitability
Use the declaration on the exact flavour and pack, particularly if allergens, gluten-free status or vegan suitability affect your choice.
What to check before choosing
Start with the amount you expect to eat, then use the per-100g label to compare recipes across different bag sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Check kcal for the whole bag or the amount you will serve. Compare kcal per 100g separately; NHS food-label guidance explains that nutrition is shown per 100g and sometimes per portion. | I want to know what my tea-break portion contains, without mistaking a smaller bag for a lower-calorie recipe. |
| Fat and salt | Read the fat and salt figures on the same nutrition label, using per-100g values to compare recipes and portion values for the amount you plan to eat. | Calories are my starting point, but I also want to see the fat and salt figures rather than judging a crisp by its flavour name. |
| Ingredients and allergens | Check the current pack for the exact flavour, including its ingredients, allergen precautions and any dietary-suitability statement. | If an ingredient or dietary restriction matters to me, a plain or sea-salt flavour name is not enough to establish suitability. |
Common buying mistakes
-
Comparing only calories per bag
A smaller bag can have fewer calories because it contains less food. The reviewed individual bags range from 22g to 40g.
If you will eat the whole bag, check its total calories first; then compare kcal per 100g to judge the recipes on the same weight basis.
-
Reading “lightly salted” as “lower calorie”
The flavour description does not establish calorie density. Tyrrells lists Lightly Sea Salted at 519 kcal per 100g, while Walkers UK lists Oven Baked Sea Salt at 438 kcal per 100g.
Use the nutrition figures for the calorie comparison, and treat flavour and dietary-suitability statements as separate information.
-
Treating a sharing bag as one portion
A per-100g figure describes the recipe, not how much you will eat. KETTLE’s Sea Salt & Crushed Black Peppercorns listing is for a sharing-format product.
If it is for one tea break, decide on a portion before serving rather than using the bag as the portion.
-
Skipping the exact pack’s allergen information
Precautions can differ between recipes. Tyrrells says its Lightly Sea Salted crisps may contain milk; a familiar flavour name cannot answer an allergen question.
Read the current ingredients and allergen declaration for the flavour you are buying.
Brand and product references
These figures describe the named products, not every flavour or pack made by each brand.
Walkers
Walkers UK lists Oven Baked Sea Salt at 96 kcal per 22g pack and 438 kcal per 100g, compared with 130 kcal per 25g pack and 518 kcal per 100g for its Ready Salted crisps.
- The Oven Baked Sea Salt bag has the lowest stated pack calories among the reviewed products.
- It is a baked potato snack rather than a conventional sliced, fried crisp; check the exact pack for allergen precautions.
Real Crisps
Tesco lists Real Sea Salt at 176 kcal per 35g bag and 503 kcal per 100g.
- The listing identifies one serving per bag, making the stated pack total straightforward to use for a whole-bag snack.
- Its per-100g calorie figure is higher than Walkers Oven Baked Sea Salt’s; check the current pack for ingredients and suitability.
Kettle Chips
KETTLE lists Sea Salt & Crushed Black Peppercorns at 505 kcal per 100g in a sharing-format listing.
- KETTLE describes this exact product as gluten-free and suitable for vegans and vegetarians.
- The per-100g figure does not specify the calories in a self-served tea-break portion.
Seabrook
Seabrook lists Sea Salted at 164 kcal per 31.8g bag and 516 kcal per 100g.
- The stated bag size and calories make it possible to assess a whole-bag portion.
- Compare its per-100g figure separately from bag totals for differently sized products.
Tyrrells
Tyrrells lists Lightly Sea Salted at 208 kcal per 40g pack and 519 kcal per 100g.
- The stated 40g pack total can be used when comparing whole-bag portions.
- “Lightly” is not a calorie comparison, and Tyrrells states that this product may contain milk.
Pipers
Pipers lists Anglesey Sea Salt at 532 kcal per 100g.
- Pipers describes this exact product as gluten-free and suitable for vegetarians and vegans.
- Use its stated per-100g calories, rather than the simple sea-salt description, when comparing calorie density.
Joybuy product options
These options include baked and popped snacks as well as individual-bag crisp multipacks. A variety pack or different flavour is not interchangeable with the exact product used for the calorie comparisons above; check its own pack before choosing.

Walkers Oven Baked Variety Pack Crisps 6 x 22g
The 22g bags provide individual portions for a break. This is a variety pack, so check each flavour’s calories, ingredients and allergen information rather than applying the Sea Salt figures to every bag.
No image available
PopChips Sour Cream & Onion 85g
This 85g bag is an option if you would rather serve your own tea-break portion. Check the pack’s serving size and allergen declaration before using its nutrition figures for that portion.

Hula Hoops Variety Multipack Crisps 12 x 24g
The multipack contains 24g bags, which may suit a break where you want an individual bag. Check the calorie and ingredient information for the particular variety you choose.
No image available
Walkers Roast Chicken Crisps 6 x 25g
The 25g bags give you a stated individual pack size. If calories are the deciding factor, read this flavour’s own pack total and per-100g figure rather than using figures for Walkers Ready Salted or Oven Baked Sea Salt.

Hula Hoops Cheese & Onion Multipack Crisps 6 x 24g
This multipack provides 24g bags for individual portions. Check the Cheese & Onion pack for its calories, ingredients and allergen information; portion size alone does not establish calorie density.
Questions about choosing crisps
How do I compare differently sized bags?
If you will eat the whole bag, compare its stated kcal first, then use kcal per 100g to compare recipes at the same weight. NHS food-label guidance notes that nutrition is given per 100g and sometimes per portion; the stated portion may not be the amount you serve.
Does “lightly salted” mean fewer calories?
No calorie conclusion follows from the flavour name. Tyrrells lists Lightly Sea Salted at 519 kcal per 100g and 208 kcal per 40g pack; Walkers UK lists Oven Baked Sea Salt at 438 kcal per 100g and 96 kcal per 22g pack. Compare both label figures for the products you are considering.
Should I check fat and salt as well as calories?
Yes, if those figures matter to your choice: they answer different questions from the calorie total. Read fat and salt per 100g to compare recipes, then check the figures for the portion you intend to eat.
Can a plain flavour name tell me whether crisps suit an allergy?
No. Read the current ingredients and allergen declaration for the exact product. Precautionary statements vary: Tyrrells states that its Lightly Sea Salted crisps may contain milk.
Is an online ingredient listing enough to choose a pack?
Use it to narrow your choices, then read the pack before eating. Tesco advises checking the physical product label because ingredients, nutrition information and allergen details can change.
