The black (general waste), brown (bottles, cans, plastics) and green (garden) are the regular size - and we can get the monster bins which are 50% bigger if there is a good reason - but the blue (used to be a plastic box with elesticated plastic cover - for paper and cardboard) is the small/skinny size. That is the one that fills up and the excess goes into general waste.
For a small household like ours it works OK although we weren’t sure when the frequency was first reduced, then reduced again and again. At least we have all plastic bins, not bags that the dogs, cats, foxes and bears will shred and scatter around.
The weekly cycle is black - blue - black - brown - black - blue and so on with the green on a separate 4 weekly cycle for 6 months of the year.
