LineGrid

A lightweight, pixel-perfect grid overlay to help you position and align your UI, unit frames, action bars and addons. Works on both Retail and WoW Forever.

Features
- Pixel-perfect grid that matches your real screen pixels, regardless of your UI scale.
- Center lines (horizontal and vertical) marking the exact middle of your screen, perfect for symmetrical layouts.
- Custom colors: pick your own color and opacity for the grid lines and the center lines separately.
- Adjustable square size in pixels, saved as your default.
- Grid is built outward from the center, so both sides of the screen always mirror each other.
- Does not block the mouse: keep it open while using Edit Mode, ElvUI, or any addon mover.
- Automatically redraws when you change resolution or UI scale.
- Zero dependencies, very small footprint.

Commands
/linegrid - Show or hide the grid
/linegrid 20 - Set the square size to 20 pixels and show the grid
/linegrid config - Open the settings panel

Settings
Go to Esc > Options > AddOns > LineGrid to customize the grid:
- Square size (4 to 512 pixels). This value is used every time you type /linegrid.
- Grid lines color and center lines color, with opacity. Changes show up live while the grid is open.
- Restore default colors (red center lines, black grid lines) with one click.
