ComfyUI_aspect_ratios

| English | 日本語 |

I created an aspect ratio selector for ComfyUI based on sd-webui-ar.

Usage

Replace Empty Latent Image with Aspect Ratios Node.

• size: Reference size
• aspect_ratios: Set aspect ratios
• standard: Choose whether the reference size is based on width or height
• swap_aspect_ratio: Swap aspect ratios (change 1:2 to 2:1, for example)
• batch_size: Number of images to create

Configuration

A configuration file, aspect_ratios.txt, will be created in ComfyUI\custom_nodes\ComfyUI_aspect_ratios.

Configure the aspect ratios in the file aspect_ratios.txt, following the specified format. For example:

1:1, 1/1 # 1:1 ratio based on minimum dimension
3:2, 3/2 # Set width based on 3:2 ratio to height
4:3, 4/3 # Set width based on 4:3 ratio to height
16:9, 16/9 # Set width based on 16:9 ratio to height
1.618:1, 1.618/1
# 1.414:1, 1.414/1

• The initial 1:1 is what is displayed in the UI.
• The next 1/1 is the value processed internally.
  • Do not include any characters other than numbers and /.
• The last line, # 1:1 ratio based on minimum dimension, is a comment.

The line starting with # is a comment and will not be read.

Example

Setting standard to width results in a width-based reference, with a width of 1024 and a height of 512.

---

Setting standard to height results in a height-based reference, with a height of 1024 and a width of 2048.

Understanding Aspect Ratios

Aspect ratios represent the ratio of width to height. For example, the aspect ratio "16:9" signifies a ratio where the width is 16 and the height is 9.

Simple Interpretation "16:9 = Width:Height"
