Snackers setting a whole-bag allowance
If you want one bag for a film or episode, compare its total calories rather than estimating a serving from a sharing bag.
Who is a single bag useful for?
An individual bag makes the amount you intend to eat easier to identify; whether that amount suits you still depends on its weight and label.
Shoppers weighing portion size against calories
A 30g serving may appeal more than a 17g to 22g bag if you are comfortable with its stated calories. Compare salt and fat as well as pack weight.
People checking ingredients and allergens
Compare the statement on the exact flavour and pack you intend to buy. Possible milk, gluten, soya or sulphite exposure differs between the products discussed here.
What should you compare?
Decide how much of the pack you expect to eat, then compare calories, pack weight and salt on that basis. Per-100g figures help you compare products of different sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bag calories | Check calories for the full bag if you will eat it all. If the label gives a smaller serving, check how many servings the bag contains. | I want to know the calories in the amount I will actually eat, without measuring crisps from an open sharing bag. |
| Pack weight | Compare grams alongside calories. Use per-100g energy values to distinguish a smaller portion from a difference in energy density. | A 17g bag may fit my planned snack, or I may prefer a larger stated serving and account for its calories. |
| Salt and other label values | Compare salt for the amount you will eat and per 100g. Check the label for fat and saturates too; do not assume a baked product has less salt. | Calories are not my only consideration, especially when choosing between savoury flavours with different salt figures. |
| Pack format | Check the weight of each bag in a multipack and the serving information on sharing packs. A promotion does not change the nutrition figures. | I would rather plan one bag for the evening than let an offer decide the amount I eat. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 survey of 611 Northern Ireland adults, 49% said a promotion made them more likely to buy chocolate confectionery, crisps and snacks; that figure describes purchasing, not consumption. |
| Ingredients and allergens | Read the ingredients and allergen statement for the specific product and flavour. Check them again when changing from potato crisps to lentil- or wheat-based snacks. | I need a snack whose current pack information fits my ingredient requirements, not just a calorie figure that fits my plan. |
What is easy to overlook?
-
Assuming the lowest-calorie bag is the same-sized snack
Seabrook lists 75 kcal for its 17g Sour Cream & Chive Lentil Hoops bag; Tyrrells lists 140 kcal for a 30g serving of Sweet Chilli & Red Pepper Lentil Crisps. Those amounts are not equivalent portions.
Choose an amount you expect to eat, then check both its weight and its stated calories.
-
Comparing calories but overlooking salt
Walkers lists 0.19g salt for a 22g Oven Baked Sea Salt pack. Seabrook lists 0.39g for an 18g Salt & Vinegar Crunchies bag, so their calorie figures do not tell the whole story.
Use per-bag salt for the portion you plan to eat and per-100g salt when comparing differently sized products.
-
Letting a multipack offer set the portion
A multipack contains several individual bags. Buying one does not mean that the nutrition figures printed for one bag apply to the whole pack.
Check how many bags are included and choose the number you intend to eat before opening the pack.
Brand and product-line references
These examples show how pack size and nutrition differ across particular products; the figures do not apply to every flavour from a brand.
Walkers
Walkers Oven Baked Sea Salt is an individually portioned potato-crisp option listed by Walkers at 96 kcal per 22g pack.
- Walkers lists 2.8g fat, 0.3g saturates and 0.19g salt per pack.
- The 22g pack is smaller than a 30g serving. Check the pack’s allergen statement, including its possible milk, wheat, gluten, barley, soya, celery and mustard exposure.
Seabrook
Seabrook lists 75 kcal for a 17g Sour Cream & Chive Lentil Hoops bag, 81 kcal for 18g Salt & Vinegar Crunchies and 82 kcal for 18g Sea Salted Crunchies.
- Each of these products has a stated calorie figure for one small bag.
- Allergen statements differ: the lentil hoops may contain milk, soya and sulphites; the checked Crunchies may also contain cereals containing gluten.
Tyrrells
Tyrrells lists 140 kcal per 30g serving of Sweet Chilli & Red Pepper Lentil Crisps and 141 kcal per 30g serving of Sour Cream & Onion Lentil Crisps.
- The stated 30g serving offers a different portion-size choice from a 17g or 18g snack bag.
- The respective salt figures are 0.63g and 0.60g per 30g. Tyrrells’ own less-fat comparison with standard potato crisps is not a comparison of calories or salt.
KETTLE Chips
KETTLE Chips Lightly Salted is a hand-cooked potato crisp; the brand lists 516 kcal and 29.5g fat per 100g.
- The brand describes this particular product as gluten-free and suitable for vegans and vegetarians.
- For a set snack allowance, check the portion you will take from a larger pack rather than treating the per-100g figure as a bag total.
McCoy's
McCoy's Salt & Malt Vinegar is a standard potato crisp listed by McCoy's at 529 kcal and 2.1g salt per 100g.
- The per-100g label allows a size-adjusted comparison with other crisps.
- It contains barley malt vinegar extract and may contain milk, soya, gluten and mustard. Check the intended serving for its calorie and salt totals.
REAL Hand Cooked Crisps
REAL lists 515 kcal and 30g fat per 100g for its Sea Salt hand-cooked potato crisps, with 35g and 150g bag sizes.
- REAL describes its range as vegetarian and gluten-free; check the particular pack when those details matter.
- The 150g bag contains more than one 35g-sized amount, so decide how much you will serve before using its nutrition figures for a TV-night snack.

Questions about TV-night crisps
Should I compare calories per bag or per 100g?
Use the whole-bag figure when you expect to eat the whole bag, and compare per-100g figures when pack sizes differ. The NHS notes that a manufacturer’s stated portion may not match the amount you actually eat, so check how many portions are in a sharing pack.
Are baked crisps necessarily lower in calories and salt?
No conclusion about every baked crisp follows from its cooking method. Walkers lists 96 kcal and 0.19g salt for its 22g Oven Baked Sea Salt pack; check the figures for the exact flavour and portion you are buying.
Is a smaller, lower-calorie bag always the right TV snack?
Not if you would prefer a larger planned portion. Seabrook lists 75 kcal for 17g Sour Cream & Chive Lentil Hoops, while Tyrrells lists 140 kcal for a 30g serving of Sweet Chilli & Red Pepper Lentil Crisps. Compare the quantity as well as calories and salt before choosing.
What allergens should I check in crisp-style snacks?
Read the statement on each specific pack. Seabrook says its Sour Cream & Chive Lentil Hoops may contain milk, soya and sulphites; its checked Crunchies may also contain cereals containing gluten. Walkers lists further possible allergens for Oven Baked Sea Salt, including wheat, barley, celery and mustard.
