Features

Resolution Selector

  • Model-optimised resolution presets (portrait, landscape, square)
  • Empty latent output for direct KSampler connection
  • Custom width/height inputs with independent multiplier and latent

Installation

# 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
