Measure before you buy.

The short answer
A good caddy liner is a fit problem before it is a shopping problem. Know the caddy size, then pick the liner.
17:02Buying by vibes is how you end up with a tiny bag doing mountaineering over a giant rim.
17:03Start with the caddy. Then choose the bag.
What size means
Food caddies are usually described in litres. That tells you capacity, but it does not tell you everything about shape.
17:08Two caddies can hold a similar amount but have different rims, heights and corners. The bag has to deal with the shape, not the label.
17:09For a kitchen food caddy, check three things: litre size, rim width and enough spare bag to tie it when full.
17:10Council caddies
Councils do not all use one identical kitchen caddy. Some use small indoor caddies, some issue different outdoor food bins, and some rules vary by property.
17:15That is why a fixed size table in a blog is the wrong tool. It goes stale. Use the checker instead.
17:16Very glamorous sentence: local waste-service details should live where they can be updated.
17:17How to choose
Step one: use the council bin checker if your council issued the caddy.
17:22Step two: if your caddy is not listed, measure the rim and check the litre size on the bin or council page.
17:23Step three: choose from the Generation earth liner range and leave yourself enough bag to tie, not just cover the rim.
