ResolutionSelector for ComfyUI

Resolution Selector Plus - Custom node for ComfyUI

Custom node for ComfyUI providing easy resolution and empty latent selection for image generation workflows.

Features

Resolution Selector

• Model-optimised resolution presets (portrait, landscape, square)
• Empty latent output for direct KSampler connection, with the correct latent channel count per model (4 for SD 1.5 / SDXL, 16 for Flux / Qwen Image / Z-Image)
• Custom width/height inputs with independent multiplier and latent

Note: with model set to "All" the latent uses 4 channels. Pick the specific model (Flux, Qwen Image, Z-Image) to get a 16-channel latent for that model's sampler.

Installation

ComfyUI Manager (recommended)

In ComfyUI, open Manager > Custom Nodes Manager, search for ComfyUI_ResolutionSelectorPlus, click Install, then restart ComfyUI.

Manual install

# Change to the directory you installed ComfyUI
cd pathTo/ComfyUI

# Change to the custom_nodes directory
cd custom_nodes

# Clone the repo into custom_nodes
git clone https://github.com/bradsec/ComfyUI_ResolutionSelectorPlus.git

# Restart ComfyUI

Usage

Resolution Selector Plus

Add Node: Add Node > utils > Resolution Selector Plus

Inputs:

• model (dropdown) - Select your image generation model or "All" for all resolutions
• resolution (dropdown) - Choose from model-optimized presets with aspect ratios (e.g., "1920x1080 (16:9 Landscape)")
• resolution_multiplier (dropdown) - Multiply preset resolution (1x, 2x, 3x, 4x)
• batch_size (number) - Number of latent samples to generate (1-64, default: 1)
• custom_width (optional) - Override with custom width (0-4096, step 8)
• custom_height (optional) - Override with custom height (0-4096, step 8)
• custom_multiplier (optional) - Independent multiplier for custom dimensions (1x, 2x, 3x, 4x)
• custom_batch (optional) - Number of latent samples for custom resolution (1-64, default: 1)

Outputs:

• width (INT) - Preset resolution width in pixels
• height (INT) - Preset resolution height in pixels
• latent (LATENT) - Empty latent tensor for preset resolution (batch_size samples)
• custom_width (INT) - Custom width (0 if not set)
• custom_height (INT) - Custom height (0 if not set)
• custom_latent (LATENT) - Empty latent tensor for custom resolution (custom_batch samples)

Example Workflows:

Basic preset with multiplier:

Resolution Selector Plus (model: SDXL, resolution: "1024x1024 (1:1 Square)", multiplier: 2x)
  -> width: 2048, height: 2048
  -> latent -> KSampler

Custom dimensions with independent multiplier:

Resolution Selector Plus (custom_width: 1024, custom_height: 768, custom_multiplier: 2x)
  -> custom_width: 2048, custom_height: 1536
  -> custom_latent -> KSampler

Using "All" model option:

Resolution Selector Plus (model: All, resolution: "1920x1080 (16:9 Landscape)")
  -> Shows all 74 unique resolutions from all models

Compatibility

Dual API: exports the legacy V1 NODE_CLASS_MAPPINGS and a V3 comfy_entrypoint (comfy_api). Verified on ComfyUI 0.25.0. On builds whose loader reads NODE_CLASS_MAPPINGS first, the V1 path is used and comfy_entrypoint is skipped, so nodes are not registered twice.
