If you're designing a square-shaped icon, like the one for Terminal seen above, then consider using these common measurements \(in pixels\) for each icon:

### Drop Shadow
+{% hint style="warning" %}
+This section is deprecated, and will be removed in the future, following the resolution of [elementary/icons#1353](https://github.com/elementary/icons/issues/1353). New application icons should not use a drop shadow.
+{% endhint %}

To draw the shadow, you'll start by drawing a rectangle. Then fill it with a linear gradient that is perpendicular to the bottom margin of the icon. The gradient has three stops, the first and last of which have zero opacity. Then this entire shape is set to **60% opacity**.
