Resolution Picker 🪽

Every model has its magic resolutions - 1024x1024 for SDXL, 1344x768 for SDXL widescreen, 1216x832 for 3:2, and so on - and remembering them is a tax you pay every time you build a workflow. Resolution Picker 🪽 is the node that ends the remembering: pick an aspect ratio, pick a resolution from a curated list, and get width and height out as clean INTs to feed an Empty Latent.

How it works

Two dropdowns, cascading:

• aspect_ratio - eight options: 1:1 (Square), 4:3 (Standard), 3:2 (Photo), 16:9 (Widescreen), 21:9 (Ultrawide), 9:16 (Portrait Mobile), 3:4 (Portrait Standard), 2:3 (Portrait Photo).
• resolution - the list of resolutions for that ratio. Pick 16:9 and you get 720p/1080p/1440p/4K/8K plus model-tuned sizes; pick 1:1 and you get SD1.5's 512, SDXL's 1024, Qwen-Image's 1328, 4K, and friends.

The output is width, height (both INT), and an aspect_ratio string. The resolution labels carry the context inline - 1024x1024 (SDXL/SD3/Flux), 1920x1080 (1080p FHD), 1536x640 (SDXL) for 21:9 - so you always know what you're selecting and why it's there. There are 77 resolutions across the eight ratios, covering SD 1.5, SDXL, SD3/SD3.5, Flux, Qwen-Image, DALL-E 3, Midjourney, Hunyuan, Kolors, and plain video standards.

Why you'd reach for it

It's the plumbing-node version of "one less thing to think about." The workflow move: Resolution Picker → width/height into Empty Latent Image, and you've got a canvas that's instantly right for whatever model you're on without looking anything up. The aspect-ratio dropdown also gates the resolution list (that's the cascading widget doing its thing), so you can't accidentally pick a 16:9 resolution while set to 1:1 - the list just changes. If you build a lot of fresh workflows, the "which resolution is native for Flux again?" question disappears entirely.

Installing it

cd ComfyUI/custom_nodes
git clone https://github.com/ThepExcel/ComfyAngel.git

Restart ComfyUI, or search "ComfyAngel" in ComfyUI Manager. Only dependency is Pillow; no model files.

One honest caveat: the resolution list is fixed in the code - you can't add your own custom entry without editing the pack. For most people the 77 presets are more than enough, and the labels make even unfamiliar sizes self-explanatory. It won't change your life, but it'll quietly save you a lookup a week.
