Potty Mouth plants come in pots that they’ll usually be happy in for at least a year, so there’s no need to get your hands dirty repotting them for quite a while.
Also, a lot of houseplants are quite happy in pretty snug pots. However, if you can see a lot of roots (not just one or two) growing out of the drainage holes in your plant's pot it might be time to consider repotting.
If this is the case, be sure to only go up 2-3cm in size, otherwise you might stress your plant out and send it into shock.
The plant sizes displayed are the diameter. So for example, if your plant is in a 9cm currently, you might want to graduate to an 11cm pot.
