Size Guide

Not sure which size to grab? Here's the full fit guide across the PurePrep range — lids, bags, and the faucet tray.

Stretch Lids — 6-Piece Set

Every set includes all six sizes below. The silicone stretches, so if you're between sizes, size up.

Size	Diameter	Best For
XS — 6 cm	~2.4 in	Small cans, sauce jars, shot glasses, small cups
S — 8 cm	~3.1 in	Standard mugs, tuna cans, small bowls, half a lemon or lime
M — 10 cm	~3.9 in	Soup cans, yogurt containers, medium bowls, half an avocado
L — 12 cm	~4.7 in	Cereal bowls, large mugs, medium pots, cut melon
XL — 15 cm	~5.9 in	Dinner bowls, medium mixing bowls, wide pots, watermelon quarter
XXL — 18 cm	~7.1 in	Large mixing bowls, wide pans, salad bowls, large containers

Tips: the lid stretches, so go up a size if you're between. A dry rim gives the strongest seal, and the more you stretch it over the edge, the tighter it grips — it even works on irregular shapes.

Silicone Storage Bags — 3-Pack

Each 3-pack includes one of every size, so you're covered from snacks to bulk storage.

Size	Capacity	Best For
Small	500 ml	Snacks, portions, on-the-go
Medium	1000 ml	Sandwiches, leftovers, everyday meal prep
Large	1500 ml	Bulk storage, freezer, batch cooking

Silicone Faucet Tray

Measure the back edge of your sink where the faucet sits, then match it to a length below. When in doubt, size up so the tray spans the whole splash zone.

Size	Length	Full Dimensions	Best For
Small	37 cm / 14.6 in	37 × 14 × 2.1 cm	Compact & bar sinks
Medium	45 cm / 17.7 in	45 × 14 × 2.1 cm	Most standard kitchen sinks
Large	61 cm / 24 in	61 × 14 × 2.1 cm	Wide, double & farmhouse sinks

Good to know: every size is 14 cm (5.5 in) deep and 2.1 cm tall. The center notch fits around the faucet base, and the tray folds flat for storage.
