ResolutionSelector - ComfyUI Built-in Node Documentation

The Resolution Selector node calculates the pixel width and height for an image based on a chosen aspect ratio and a target total resolution in megapixels. It is useful for generating consistent dimensions for other nodes, such as the Empty Latent Image node. The output dimensions are always rounded to the nearest multiple of 8.

Inputs

Parameter	Description	Data Type	Required	Range
`aspect_ratio`	The aspect ratio for the output dimensions (default: `"1:1 (Square)"`).	COMBO	Yes	`"1:1 (Square)"` `"3:2 (Photo)"` `"4:3 (Standard)"` `"16:9 (Widescreen)"` `"21:9 (Ultrawide)"` `"2:3 (Portrait Photo)"` `"3:4 (Portrait Standard)"` `"9:16 (Portrait Widescreen)"`
`megapixels`	Target total megapixels. 1.0 MP ≈ 1024×1024 for a square aspect ratio (default: 1.0).	FLOAT	Yes	0.1 - 16.0

Outputs

Output Name	Description	Data Type
`width`	The calculated width in pixels, which is a multiple of 8.	INT
`height`	The calculated height in pixels, which is a multiple of 8.	INT
