[RMMZ] ARE THERE ANY TEMPLATES FOR 16X16 TILESETS?

I just made the move from 2k3 to MZ, and I want to use the 16x16 option for tilesets, but I'm not sure what size I should make it or where to draw autotiles, since before I'd just use the RTP and draw over it to know what goes where. I've looked on the internet for 16x16 MZ tilesets for me to use as a base to know where to draw autotiles and the such, but I just can't find one that's already formatted to MZ's editor. I'm rather new to making tilesets in general, so I'm just confused about how I can tile in 16x16. Any tips or suggestions would be greatly appreciated. Thank you!
