How to Change Canvas Size in Illustrator?

When working on a project in Adobe Illustrator, everything takes place on an artboard. This is Illustrator's general term for a canvas, and multiple artboards can exist within the same workspace. Canvas size in Illustrator is always flexible, and it's easy to change an artboard's dimensions at any point in the creative process. Below, we've outlined how to resize an artboard to your own needs, or to have Illustrator adjust an artboard automatically so that your design always fits. 

How to Manually Resize an Artboard

  1. First, open the Illustrator document that you'd like to edit. Click on the main File tab, and then choose "Document Setup". This will bring up a new window, with a variety of general document settings. 
  2. Click on "Edit Artboards" to bring up all of the artboards in your project. Move your cursor over the artboard you wish to resize, and then press Enter to bring up the Artboard Options menu. 
  3. Here, you'll be able to enter a custom Width and Height, or choose from a range of preset dimensions. While in this menu, you can also just click and drag the artboard handles to resize them. When you're happy with the new sizing, press OK, and your changes will be updated. 
  4. Finally, you can resize your artwork to fit the artboard's new dimensions. To do this, press CTRL+A (Cmd+A on Mac) to select everything on the artboard, and then press CTRL+G (Cmd+G) to create a group. 
  5. Now when you resize the artwork, it will retain the same proportions. Hold down the Shift key, and drag a corner of the selected group to make it larger or smaller.   

How to Automatically Resize an Artboard

With the "Fit to Artwork Bounds" feature, canvas size in Illustrator will automatically adjust to fit the artwork contained inside. To enable this feature, go to the main Objects menu and select "Artboards" > "Fit to Artwork Bounds".
