ComfyUI-ResolutionSelector

A simple and editable resolution preset selector node for ComfyUI.

This custom node lets you quickly select common image or video resolutions from a dropdown list, or define your own manual resolution.
Presets are stored in a separate resolutions.json file that you can freely edit. The node also generates an Empty Latent (1×4×H/8×W/8), so you can plug it directly instead of an Empty Latent Image node.

Features

• ✅ Dropdown list of predefined image/video resolutions
• ✅ Easy manual input via “Custom (manual input)” option
• ✅ External resolutions.json file — editable at runtime
• ✅ Works with Reload Custom Nodes (no restart)
• ✅ Clean output: (width, height) for direct wiring to Empty Latent Image, WANVideo, etc.

   git clone https://github.com/dodemedexter/ComfyUI-ResolutionSelector.git
   

Usage

Find it under the Utilities category:
Utilities → Resolution Selector
Select a preset (e.g. WAN - 9:16 HD [544x960 portrait])
Connect the outputs:
(width, height) → Empty Latent Image

🧾 Editing the presets

The list of resolutions is stored in resolutions.json. You can edit this file freely to add, rename, or remove entries.

Example:
{
"IMAGE 1:1 [1024x1024 square]": {"width": 1024, "height": 1024},
"WAN - 9:16 HD [544x960 portrait]": {"width": 544, "height": 960},
"Custom (manual input)": {"width": 512, "height": 512}
}

After editing, just click Reload Custom Nodes in ComfyUI Manager — no need to restart.

Dependencies

None. This node uses only the standard ComfyUI API and the Python standard library.
