Best-Res (area+scale)

BestResolutionFromAreaUpscale

The most efficient way of selecting an optimal resolution: image size selected indirectly - by the total desired resolution (area) + aspect ratio... ... PLUS, account for the immediate upscale right away. Desired resolution (aka image area/megapixels/pixel count) is specified with a side of a square image. This isn't accidental: most models disclose what image resolution they're trained on, and usually they're square: - SD 1.5 - 512x512 pixels - SDXL - 1024x1024 pixels By simply providing this single number and setting your aspect ratio/orientation, you get the width and height to produce the closest total resolution to the training set, while also respecting image proportions and step-rounding.
