A standard 20g bag of Quavers contains 88 kcal and 4.5 syns on Slimming World. They're one of the most popular low-syn crisps on plan — cheaper in syns than Mini Cheddars (6.5 syns) and most standard Walkers bags (6–7 syns), but slightly higher than Wotsits Crunchy (4 syns).
The light, airy texture means a 20g bag feels more generous than the weight suggests. Most members find a bag of Quavers genuinely satisfying as an afternoon snack without spending too much of the daily allowance.
A standard 20g bag of Walkers Quavers contains 4.5 syns and 88 kcal. The multipack bags are 16g each and work out at 3.5 syns — a small but useful saving if you buy in bulk.

| Quavers Cheese (standard bag) | 20g | 88 kcal | 4.5 | 4 |

The multipack 16g bags are the better format for anyone on plan — slightly lower syn per bag and portion-controlled by design. A multipack box keeps one bag clearly as one portion, which makes it easier to track through the week.
Quavers at 4.5 syns per 20g bag sit in the lower half of the crisp syn range. Most standard fried crisps (Walkers, Pringles, Tyrrell's) cost 6–8 syns per bag. Quavers are lower because they are a puffed corn snack rather than a fried crisp — the puffing process uses less oil, which keeps fat content and calories down.
A 20g bag of Quavers contains 4.3g of fat. A 25g bag of standard Walkers Ready Salted contains around 7g of fat. That fat difference is the main reason Quavers cost fewer syns per gram eaten.

Wotsits Crunchy and Snack-a-Jacks are both marginally lower syn than a standard 20g Quavers bag — but the multipack 16g Quavers at 3.5 syns beats both. If you're choosing between the three, buy Quavers multipacks for the best syn value.
Yes — crisps are synned rather than banned on Slimming World. Any crisp fits within the daily 5–15 syn allowance. A bag of Quavers at 4.5 syns leaves at least 10 syns for the rest of the day's treats if you're on 15 syns per day.
The approach that works best: buy multipacks, plan one bag as the afternoon snack, and treat it as a guaranteed daily treat rather than an impulse buy. Members who ban crisps entirely tend to end up eating half a tube of Pringles eventually. Members who plan one bag of Quavers every afternoon stay on track.
The Quavers multipack 16g bag at 3.5 syns is the lowest syn mainstream cheese-flavoured crisp available from UK supermarkets. Wotsits Crunchy (4 syns per 16.5g) and Snack-a-Jacks (4 syns per 19g) are close behind. No mainstream fried crisp comes in below 4 syns for a reasonable bag size.
Plain rice cakes are lower still — a standard 4g plain rice cake is around 0.5 syns. They satisfy crunch but not the cheese or flavour craving most crisp lovers are after. For genuine crisp satisfaction at low syn cost, the Quavers multipack bag is the best mainstream option.
