📐 Resolution Preset

Every ComfyUI user has typo'd a resolution into an Empty Latent node and ended up with a 1023×1025 latent that the VAE quietly hates. ResolutionPreset is the node that makes that impossible: it outputs an exact width and height, guaranteed divisible by the alignment you choose, picked from presets, direct input, or a draggable canvas widget.

That's the whole job, and it does it without lecturing you. It has no classic inputs - everything lives in the widget - and its two outputs are simply Width (INT) and Height (INT), which you wire into an Empty Latent Image or a loader's width/height ports.

The alignment bit

Dimensions snap to an alignment you pick: 8, 16, 32, or 64 pixels. Multiples of 8 is the baseline that samplers and VAE decode are happiest with, and it's the convention every workflow assumes; 16/32/64 are for when you're being strict about patch sizes. The clever fallback: if you choose a built-in preset that can't satisfy the current alignment, the node falls back to that preset's 8px alignment so the output is still exact - you never get a "1, the preset didn't fit" empty state.

How you pick dimensions

• Eleven built-in presets, deliberately model-agnostic - including the portrait/landscape pair 1080×1920 and 1920×1080 that anime checkpoints and video tools keep wanting.
• Personal presets you save yourself, each keeping its own alignment, stored in the current ComfyUI user directory (per user, not baked into the workflow).
• Direct width/height entry, which still snaps to alignment.
• A draggable canvas with corner handles, so you can eyeball an aspect ratio and get a clean number out.

The honest limits

The README says it better than I can paraphrase: this node doesn't compute a target resolution from megapixels, doesn't recommend a model, and performs no image operations. If you want "0.5MP portrait" style math that derives dimensions from a pixel budget, use ComfyUI's own ResolutionSelector instead - that's its lane, not this node's. ResolutionPreset is for "I want exactly 1024×1024, exactly divisible by 8, and I don't want to catch myself typing 1042."

Install

Same pack as the rest of Aaalice's nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/Aaalice233/ComfyUI-Aaalice-Nodes.git
cd ComfyUI-Aaalice-Nodes
pip install -r requirements.txt

or search ComfyUI-Aaalice-Nodes in ComfyUI Manager, then restart. No models, certifi is the only extra dependency. It's a V3-node pack, so it wants a recent ComfyUI - classic canvas and Nodes 2.0 work, App Mode doesn't.

It's a small node with a small, exact job. If you've ever fought a latent whose side length wasn't divisible by 8, you'll appreciate it exactly once per session - which, over a year of sessions, is a lot of saved annoyance.
