<h1 id="resolution-normalizer-(comfyui-node)">Resolution Normalizer (ComfyUI Node)</h1>Resolution Normalizer is a utility node for ComfyUI that rescales image resolutions while preserving the aspect ratio.The node supports multiple normalization strategies, allowing you to normalize an image resolution by its minimum side, maximum side, or the sum of width and height.This makes it useful for preparing images for Stable Diffusion pipelines, resizing reference images, or normalizing resolutions across workflows.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/3afb6af5-3bc5-4241-9d55-4c3759d0c7e1/original=true/3afb6af5-3bc5-4241-9d55-4c3759d0c7e1.jpeg" /><hr /><h2 id="features">Features</h2><ul><li>Preserve the original aspect ratio</li><li>Normalize resolution using different strategies</li><li>Automatically upscale or downscale</li><li>Display the resulting resolution as a formatted string (debug)</li></ul><hr /><h2 id="installation">Installation</h2><ol><li>Download the zip file.</li><li>Extract it into the ComfyUI <code>custom_nodes</code> directory:</li><li>Restart ComfyUI.</li></ol>The Resolution Normalizer node will appear in the node menu.<hr /><h2 id="normalization-modes">Normalization Modes</h2><h3 id="min-mode">Min Mode</h3>Ensures the smallest side of the image equals the target value.Example:Input image: 1920 × 1080 Target value: 480 Result: 853 × 480<h3 id="max-mode">Max Mode</h3>Ensures the largest side of the image equals the target value.Example:Input image: 1920 × 1080 Target value: 1024 Result: 1024 × 576<h3 id="sum-mode">Sum Mode</h3>Ensures the sum of width and height equals the target value.Example:Input image: 1920 × 1080 Target value: 2000 Result: 1280 × 720<hr /><h2 id="example-use-cases">Example Use Cases</h2><h3 id="preparing-images-for-stable-diffusion">Preparing images for Stable Diffusion</h3>Resize images so the shortest side matches a given resolution.<h3 id="limiting-maximum-image-size">Limiting maximum image size</h3>Resize images so the longest side matches a given resolution.<h3 id="sum-of-sides">Sum of sides</h3>Resize images so the sum of the sides of the output image is equal to a given value.This is useful to keep the computational cost constant.<hr /><h2 id="example-workflow">Example Workflow</h2>Load Image ➔ Resolution Normalizer ➔ Empty Latent Image<hr />

Resolution Normalizer

Added 3 different modes: Min ModeEnsures the smallest side of the image equals the target value.Example:Input image: 1920 × 1080 Target value: 480 Result: 853 × 480Max ModeEnsures the largest side of the image equals the target value.Example:Input image: 1920 × 1080 Target value: 1024 Result: 1024 × 576Sum ModeEnsures the sum of width and height equals the target value.Example:Input image: 1920 × 1080 Target value: 2000 Result: 1280 × 720
