Symbols

Symbols is a powerful feature in Sketch that allows you to reuse elements easily across your document’s Artboards and Pages, or even multiple documents.

A Symbol is made up of two parts: a “master”, which takes the appearance of an Artboard—and an “instance”, which is a flattened representation of the master.

As you create a Symbol, you can automatically send the Symbol Artboard, or master to a separate page. When you make a change to a Symbol’s master, the changes are applied to all Artboards and Pages in your document. In addition, each instance of a Symbol can be customized with overrides. In the video below, we’ve created a quick tutorial on how you can use Symbols to save time and improve your workflow.

A Symbol instance is a single layer that mirrors the content from its master. In the Layer List it is displayed with a purple icon with syncing arrows . A common example of a Symbol is an element that is re-used throughout your design such as buttons, or a cell in a table view.

Layers

Not only that, Symbol instances can be individually resized, and you can apply resizing constraints to layers inside the Symbol to determine how they should behave when resizing.

Symbols and Other Documents

As mentioned, these Symbols can be used across multiple documents under the guise of our Libraries feature. However, take a couple of moments to get to grips with how Symbols work before skipping over to the next section.
