For a portioned potato crisp snack, Walkers Oven Baked Sea Salt provides 96 kcal per 22g pack, according to Walkers UK. Compare calories per pack as well as per 100g before choosing: a smaller packet can have fewer calories without being much lower in calories by weight. Salt and the exact flavour’s allergen statement matter too.
The useful comparison depends on whether you are packing one portion, comparing crisp recipes or checking a particular child’s dietary requirements.
An individual pack makes the serving size clear for a trip or lunchbox-style outing. Walkers UK, for example, lists nutrition for a 22g Oven Baked Sea Salt pack; check the weight of other packs rather than assuming they contain the same portion.
Look at both the whole-pack figure and calories per 100g. The first reflects the amount eaten if the packet is finished; the second helps compare products sold in different sizes.
A calorie figure cannot establish whether a flavour meets a child’s dietary requirements. Read its salt value, ingredients and allergen statement on the exact pack.
Start with the amount likely to be eaten, then compare products on the same per-100g basis. Check salt and dietary labelling separately; neither follows from the calorie figure.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Read the pack weight and calories per serving. Use calories per 100g to compare different pack sizes: Walkers UK lists Oven Baked Sea Salt at 96 kcal per 22g pack and 438 kcal per 100g. | I’m packing one snack for an outing, so I want to know what eating the whole packet would mean—not just whether the front says “baked”. |
| Salt | Compare salt for the amount likely to be eaten as well as per 100g. The stated values differ across products: Walkers UK lists 0.19g per 22g Oven Baked Sea Salt pack; Tyrrells lists 0.63g per 30g Sweet Chilli & Red Pepper lentil-crisp serving. | A lower-calorie packet may still have a salt value I want to compare with another flavour. |
| Ingredients and allergens | Read the statement for the exact flavour and pack, including any precautionary warnings. Do not carry a gluten-free or vegan claim from one product across a brand’s range. | Where a child has a dietary requirement, I need the labelling for the packet I’m actually buying. |
| Snack setting | Decide whether you need an individual pack or will serve a portion from a larger bag. For snacks at home, NHS Healthier Families advises choosing fruit and vegetables and aiming for no more than two packaged snacks a day. | For a day out, a single pack is straightforward to carry; at home, I can also consider snacks other than crisps. |
Those descriptions do not tell you how many calories are in the portion. Walkers UK lists 96 kcal for a 22g Oven Baked Sea Salt pack, while Tyrrells lists 140 kcal for a 30g Sweet Chilli & Red Pepper lentil-crisp serving.
Compare the serving you would offer, then use the per-100g figures for a comparison unaffected by pack size.
A larger bag does not define how much one person will eat. KETTLE Chips lists 516 kcal per 100g for Lightly Salted, and McCoy’s lists 533 kcal per 100g for Salted.
If using a sharing bag, serve the intended amount separately and check its weight against the label.
Walkers UK lists 0.19g salt per 22g Oven Baked Sea Salt pack. Its product information also includes precautionary allergen warnings, so the calorie figure alone cannot settle a dietary choice.
Check the salt, ingredients and allergen statement for the exact flavour, particularly where an allergy is relevant.
The Requirements for School Food Regulations 2014 concern food and drink provided to pupils in maintained schools and pupil referral units in England. That scope is different from a household choosing snacks to eat at home during the holidays.
If food is being provided through a school or organised scheme, check which rules and provider requirements apply to that setting.
These examples show why the exact product and serving matter more than a brand name alone.

Use both: per-pack calories describe the stated portion, while per-100g values help compare different pack sizes. Walkers UK lists Oven Baked Sea Salt at 96 kcal per 22g pack and 438 kcal per 100g; Tyrrells lists Sweet Chilli & Red Pepper Lentil Crisps at 140 kcal per 30g serving and 467 kcal per 100g.
The Requirements for School Food Regulations 2014 apply to food and drink provided to pupils in maintained schools and pupil referral units in England; they do not establish a rule for a household snack eaten at home. For food supplied through a school or organised scheme, check the requirements applicable to that provider.
Read the ingredients, allergen statement and any dietary claim on the exact flavour and pack. Walkers Oven Baked Sea Salt has precautionary allergen warnings, while Seabrook describes its Sea Salted product as gluten-free and suitable for vegetarians and vegans; neither product’s labelling establishes what applies to every flavour from that brand.
