Squircle

A genuinely smooth rounded rectangle, applied straight to a shape layer.

A rounded rectangle whose curvature actually changes smoothly.

A preset that builds a squircle — a smooth rounded rectangle.

Unlike an ordinary rounded rectangle, a squircle inserts a curve of smoothly changing curvature between the constant-curvature arc and the straight edge, which makes the corner read as genuinely smooth.

Installation

  1. Put the preset in the User Presets folder.
    • Windows: C:\Users\[username]\Documents\Adobe\After Effects 20xx\User Presets
    • macOS: Documents/Adobe/After Effects 20xx/User Presets
  2. Create a new shape layer.
  3. Find “Squircle” in Effects & Presets and apply it to the shape layer.
