Size Presets

ComfyUI Size Presets

Save and load image sizes — and named INT/FLOAT values — with categories.

Two nodes, one local SQLite library: classic width/height presets, plus dynamic Value Presets for any named numbers (cfg, steps, denoise, …) with typed sockets.

Features

Size Presets

• Native width / height — INT widgets you can pin and wire to Empty Latent Image, etc.
• Save / Load / Manager — categories, search, copy/move
• Switch size — swap width ↔ height
• Size = identity — 1024 × 768 (no extra naming)

Value Presets

• Dynamic fields — name + INT/FLOAT + value (up to 16); empty node allowed
• Typed outputs — each field is an INT or FLOAT socket (type fixed after create; replace via type badge)
• Reorder — drag handle + position number
• Field library — reusable defs with min / max / step, category, notes; gear → Save to library
• Same library UX — Load / Save / Manager with categories and notes
• Search — category/… · category:… · category\…, then AND tokens; optional Search in fields
• Manager — Presets + Fields tabs; edit / copy / move / delete

Quick start

Sizes

1. Add Size Presets, set width/height (or connect inputs).
2. Save preset → pick a category.
3. Load preset → click a size card.
4. Wire width / height to latent or resize nodes.

Values

1. Add Value Presets.
2. Add field → blank (pick INT/FLOAT) or from the field library.
3. Name fields, set values; gear for limits / save to library.
4. Save/load presets; outputs match field types.

---

Library

Presets are stored in db/presets.sqlite (auto-created on first use).

• Sizes: unique (category, width, height)
• Values: unique (category, preset name)
• Field defs: unique by name (shared library)

Default bucket: Uncategorised. Size, value, and field categories are separate tables.
