QuickSize for ComfyUI

<img src="QuicksizeLogo.png" width="300">

QuickSize provides easy-to-use dropdown selectors for common image resolutions across multiple diffusion models in ComfyUI.
Each node outputs width and height integers based on a predefined aspect ratio, megapixel tier (or multiplier), and orientation (horizontal or vertical). No more keeping track of native image dimensions for different models.

✨ Features

  • 🧩 Nodes for Flux, Qwen, Wan, SDXL, and SD1.5 native dimensions
  • 🖼️ Aspect ratio selector (1:1, 2:3, 4:3, 16:9, 21:9, etc.)
  • 📏 Megapixel presets (1.0 MP, 1.5 MP, 2.0 MP) or multiplier options (e.g. 1.5×)
  • 🔄 Orientation switch — flip between vertical or horizontal
  • ⚡ Clean integer outputs ready for Empty Latent Image or any node requiring width/height

📦 Installation

Option 1 — Manual

  1. Navigate to your ComfyUI installation directory.
  2. Clone this repository inside ComfyUI/custom_nodes/:
   cd ComfyUI/custom_nodes  
   git clone https://github.com/rh6423/ComfyUI-QuickSize.git
  1. Restart ComfyUI.

Option 2 — ComfyUI Manager

Search for “QuickSize” in the ComfyUI Node Registry and click Install.

🧠 Usage

  1. Add one of the QuickSize nodes (e.g., QuickSize (Flux)).
  2. Choose:
    • Megapixels / Multiplier — overall output scale
    • Aspect Ratio — 1:1, 2:3, 4:3, 16:9, 21:9
    • Orientation — horizontal / vertical
  3. Connect the width and height outputs to any node that accepts image dimensions.

Each model-specific node is tuned to its model’s recommended resolution ranges.

🧩 Included Nodes

| Node Name | Purpose | |------------|----------| | QuickSize (Flux) | Presets for the Flux model | | QuickSize (Qwen) | Presets for Qwen image model | | QuickSize (Wan) | Presets for the Wan model | | QuickSize (SDXL) | Presets for Stable Diffusion XL | | QuickSize (SD1.5) | Presets for Stable Diffusion 1.5 |

(Add or remove rows as your repository evolves.)

🧰 Size presets

Each node is implemented as an individual Python file under:

src/quicksize/

The pixel resolutions are inside each node's .py file. More user friendly resolution lists are in the backlog right now.
