Line Sizer

A slab type animation preset for After Effects.

Create equal-width text layouts in an instant—procedurally and on a single layer.

Resize all lines to match the first or set a custom target width for precise control.
Use multiple fonts & fill colors per word and choose from two leading modes:

1. Default—Scales leading proportionally, ignores glyph shape
2. Optical—Uses pixel distance between lines, adapts to glyph shape

Features

• Procedural line scaling
• Multiple fonts & fill colors per word
• Two leading modes: Default & Optical
• Bakable via "Convert Expression to Keyframes"

Limitations

• Static text only (no Source Text keyframes)
• Point Text only
