What image size should I choose for 2d game character assets?

Question

Game development

I'm making assets for a 2d game, I want to make them in a regular style (not pixel art). In general, what canvas size should I choose for the character, so that after loading into unity it is neither too small nor too large. Here is the graphic style I am using

I remember exactly that in order to have fewer problems with cross-platform (mobile games), you need to make the texture size a power of two (it seems this is a feature of compression algorithms), i.e. there are not a lot of options, sort out the boundary ones where the image becomes completely ugly or still normal, there will not be many options. It seems like a few years ago 2048x2048 was the maximum recommendation (maybe now it’s already 4k, but will they lie more)
, yes, the right ones can and should be combined into groups for storage on the same texture, but in order to optimally place them there, you also need to bind their size to the size of the texture, divided by the number of adjacent
