PixelPerfectUIScale

📐 PixelPerfectUIScale

PixelPerfectUIScale is a lightweight addon that ensures your World of Warcraft UI always uses a pixel-perfect scale.

It calculates the correct scale (768 / screenHeight) and applies it automatically when the game loads, when display settings change, or when Edit Mode is applied.

🌟 Background

This addon is a conversion of the WeakAura “Pixel perfect ui scale” created by potat0nerd:
https://wago.io/_F7SrQJMS

With the WeakAuras team announcing there will be no “Midnight release” of WeakAuras for future expansions, I wanted to preserve this functionality in a standalone addon that does not depend on WeakAuras.

This is something I rely on to keep my UI scale perfectly accurate.

✨ Features

✅ Automatically enforces pixel-perfect scale (768 / screenHeight)

✅ Custom scale modifier
You can set a personal scale multiplier using:

/ppscale modifier <number>

Example:

/ppscale modifier 1.5

This multiplies the base pixel-perfect scale by 1.5 — ideal for 4K or ultrawide displays where the default scale looks too small.

• Saved between sessions
• Supported range: 0.5 to 3.0

✅ Listens for scale-changing events

• PLAYER_LOGIN
• PLAYER_ENTERING_WORLD
• DISPLAY_SIZE_CHANGED
• UI_SCALE_CHANGED
• EDIT_MODE_LAYOUTS_UPDATED

✅ Safe handling during combat (Midnight compatible)
If you enter combat, the addon defers applying UI scale changes until you leave combat, preventing protected-call errors.

✅ Optionally syncs Blizzard’s uiScale CVars
Keeps the Settings UI consistent with the actual applied scale when enabled.
