Android game and tile size standard

[alain.roger]

Hi,

I'm new to android game development and I have several ideas to develop games. However after watching several videos about unity, I could see different tile sizes (in tiles sets).

So what is the standard tiles size to create a nice HD game ? I guess it's better to create nice and high defined tile as it is easier to reduce camera view and tile size, than increase in the game tile size.

I saw 32*32, 64*64, 128*128 pixels tiles.

So I was wondering if there is a document / standard where I can find the best practices for tile size and tiles set ?

thx
