ComfyUI CYH Aspect Ratio

A ComfyUI custom node that generates empty latent images with model-specific aspect ratios and resolutions.

Features

• Model Selection: Choose between Flux, Qwen Image, and SDXL models
• Aspect Ratios: 1:1, 4:3, 3:2, 16:9, 21:9 presets
• Orientation Control: Portrait or Landscape modes
• Resolution Scaling: Multiplier with automatic rounding to multiples of 32
• Batch Support: Generate multiple latents at once

Installation

1. Copy the Chye_ASPLatent folder to your ComfyUI custom_nodes directory
2. Restart ComfyUI

Usage

1. Add the 🔹 CYH Aspect Ratio node to your workflow

2. Configure settings:

   • Model Type: Select your target model
   • Aspect Ratio: Choose desired ratio
   • Orientation: Portrait (default) or Landscape
   • Multiplier: Scale resolution (0.1-10.0)
   • Batch Size: Number of latents to generate

3. Connect the LATENT output to your sampler

Example Workflows

Basic Generation

[CYH Aspect Ratio] → [KSampler] → [VAE Decode]

Multiplier Example

Model: SDXL
Aspect: 16:9 
Orientation: Landscape
Multiplier: 1.5
→ Output: 1536×864 latent

Resolution Reference

Model	1:1	4:3	3:2	16:9	21:9
Flux	1024×1024	1280×960	1152×768	1344×768	1792×768
Qwen	1328×1328	1472×1140	1536×1024	1664×928	1984×864
SDXL	1024×1024	1024×768	1152×768	1024×576	1344×576

Notes

• All dimensions are automatically rounded to multiples of 32
• Portrait orientation swaps width/height when appropriate
• Multiplier scales base resolution before rounding
