Sizes Pixaroma

Sizes Pixaroma is your personal list of exact resolutions, one click away. Add the width × height sizes you actually use, pick one, and the node sends out the width and height as numbers - ready to wire into an empty latent or a resize node. The twist that makes it worth it: a Portrait / Landscape button flips the whole list between tall and wide, so you add 1024 × 1536 once and use it in either orientation.

If you generate at a handful of sizes over and over, this replaces retyping the numbers each time. It's the "favorites" version of the pack's Resolution Pixaroma - that node offers preset aspect ratios, this one is your own curated exact sizes.

How it works

A fresh node starts with just 1024 × 1024. Open the settings (the gear) to add, remove, and reorder sizes, load a set of common sizes to start from, or set the snap - keep every size on a multiple of 8, 16, 32, or 64. That snap matters more than it looks: models (and their VAEs) are famously fussy about dimensions, and a size that isn't VAE-friendly produces a warning or a wasted run. Wire the two INT outputs - width and height - straight into an empty latent or any size input.

The Portrait / Landscape buttons flip the currently chosen size: Portrait makes the smaller number the width, Landscape makes the larger number the width. Square sizes are unaffected, and adding a size you already have doesn't create a duplicate - it just points you at the existing one. A small arrow folds the node down to just the selected size when you want it out of the way, and the whole thing recolors if you want.

When you'd reach for it

• You've settled on a set of working resolutions (SDXL, Flux, a video model's native sizes) and want them as one-click choices.
• You want to build an empty latent that matches an exact output size without math.
• You flip between portrait and landscape versions of the same base size and are tired of editing two WH nodes.

Install and gotchas

Standard Pixaroma install - ComfyUI Manager (search "Pixaroma") or:

cd ComfyUI/custom_nodes
git clone https://github.com/pixaroma/ComfyUI-Pixaroma

Restart. No dependencies or model downloads.

Two things worth remembering. The snap setting applies when you add sizes - add a size then toggle snap and the existing entry won't retroactively snap. And the pack-wide caveat: after an update, hard-refresh with Ctrl+Shift+R (Cmd+Shift+R on Mac) if a node looks blank; the browser cache is the usual culprit.
