The models on the BetterWaifu site are descended from SDXL, which was trained at a base resolution of 1024×1024, but was further fine-tuned on multiple aspect ratios.
All width and height measurements on BetterWaifu must to rounded to a multiple of 8. This is used to guarantee quality of generations.
By using these aspect ratios for your generations, you will get the most optimal results — here are some recommendations. Standard designation usually guarantees a higher quality.
