Packet-conscious snackers
If you expect to finish one packet at your morning break, its declared packet calories and weight tell you more about that break than a per-100g figure alone.
Who is this choice for?
Shoppers checking more than calories
Compare salt and saturates on the same serving basis, and read the ingredients and allergen statement for the exact flavour. A calorie figure cannot answer those separate questions.
People choosing a multipack or sharing bag
An individual packet sets out a portion; a larger bag calls for a decision about how much to serve. Tyrrells, for example, lists five 30g servings in its 150g Lightly Sea Salted bag.
What should you compare?
Start with the amount you will eat at one break, then compare the other label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Packet calories | Find the kcal for the whole packet or your intended serving. Check its weight before comparing it with another pack. | I expect to finish one packet at my break, so I want its total calories rather than only a per-100g figure. |
| Portion format | Check whether the pack contains one serving or several. Tyrrells lists 208 kcal for its 40g Lightly Sea Salted pack, but 156 kcal per stated 30g serving from its 150g bag. | A single packet makes my planned portion clear; with a sharing bag, I would serve the amount I intend to eat. |
| Salt and fat | Compare salt, fat and saturates for the same packet or serving basis. The Food Standards Agency says traffic-light labels, where present, distinguish these measures from calories. | Even when I choose by packet calories, I also want to see the salt and saturates figures for that flavour. |
| Ingredients and allergens | Read the exact flavour’s ingredients, allergen warnings and any stated dietary-suitability information on the pack. | A plain-sounding flavour name is not enough if I need to avoid an ingredient or allergen. |
Common buying mistakes
-
Comparing only calories per 100g
A 22g packet and a 40g packet represent different amounts to eat, even when both labels also give values per 100g.
Compare the declared calories for the whole packet or the serving you plan to have. Use per-100g values when you want a comparison at the same weight.
-
Assuming every baked flavour has the same figures
Walkers UK’s 96 kcal declaration applies to a 22g Oven Baked Sea Salt packet. Another flavour or pack format needs its own label checked.
Confirm the packet calories, salt and allergen statement for the particular baked crisps you are buying.
-
Treating a sharing bag as one serving
Tyrrells lists five 30g servings in its 150g Lightly Sea Salted bag, with 156 kcal declared per serving. Eating a different amount changes the calorie total.
Check the serving weight and portion out the amount you intend to eat before your break.
-
Letting a calorie figure stand in for the whole label
Calories, salt and saturates are separate measures, while ingredient and allergen statements can differ between flavours.
Read the exact pack’s nutrition and ingredient information, particularly when changing flavour or pack format.
Brand and product-line references
These examples show why a brand name alone cannot settle a packet-calorie comparison: the named products and serving sizes matter.
Walkers
Walkers lists both conventional crisps and an Oven Baked range, allowing a comparison of specific packets within the brand.
- Walkers UK declares 96 kcal per 22g Oven Baked Sea Salt packet and 127 kcal per 25g Roast Chicken packet.
- Those figures apply to the named flavours and sizes; check each flavour’s allergen statement separately.
Tyrrells
Lightly Sea Salted comes in an individual pack and a larger bag with stated servings.
- Tyrrells declares 208 kcal for its 40g pack and 156 kcal per 30g serving from its 150g bag.
- The larger bag’s per-serving figure does not describe the calories in the whole bag.
Kettle Chips
For Sea Salt and Crushed Black Peppercorns, Kettle Chips gives nutrition figures per 100g.
- The brand declares 505 kcal and 27.3g fat per 100g for that flavour.
- Check the pack weight or stated serving before comparing its tea-break calories with an individual packet.
Seabrook
Seabrook provides per-bag nutrition for its Sea Salted crinkle-cut crisps.
- Seabrook declares 164 kcal and 0.4g salt per 31.8g Sea Salted bag.
- The brand’s dietary-suitability statements for Sea Salted should not be assumed for other flavours.
Pipers
Pipers Anglesey Sea Salt is an example with published nutrition values per 100g.
- Pipers declares 532 kcal and 0.94g salt per 100g for Anglesey Sea Salt.
- Check the weight of the pack you choose to work out what its stated nutrition basis means for your portion.
Real Crisps
REAL Sea Salt is sold in 35g bags within a 24-pack case.
- REAL Hand Cooked Crisps declares 515 kcal and 1.3g salt per 100g for REAL Sea Salt.

Questions about choosing crisps
Which calorie figure matters for one tea-break packet?
Use the calories for the whole packet if you expect to eat it all. Walkers UK declares 96 kcal for its 22g Oven Baked Sea Salt packet, while Tyrrells declares 208 kcal for its 40g Lightly Sea Salted pack; a per-100g figure alone does not describe either whole packet.
Does a lower packet-calorie figure also mean less salt?
Not necessarily: calories and salt are separate label measures. The Food Standards Agency explains that traffic-light labels, where present, show salt alongside fat, saturates and sugars; compare the figures for the portion you intend to eat.
Should I check allergens on plain or sea-salt crisps?
Yes. Check the ingredients and allergen statement for the exact product rather than relying on its flavour name. Walkers UK gives precautionary allergen advice for Oven Baked Sea Salt, while Seabrook describes its own Sea Salted product as gluten-free; neither statement establishes the status of other flavours.
How do I compare a sharing bag with a single packet?
Choose the amount you would eat from the larger bag, then compare calories for that serving with the calories in the whole single packet. Tyrrells lists five 30g servings in its 150g Lightly Sea Salted bag and one serving in its separate 40g pack.
