The fastest way to resize your canvas

Open the Artboard tool from the left toolbar (it looks like a rectangle with corner handles), then click on your canvas to select it. The artboard dimensions appear in the Properties panel on the right side of the screen. Change the width and height numbers directly, or drag the artboard edges with your mouse to resize it visually. When you're done, press Enter or click elsewhere to confirm.

If the Properties panel isn't visible, go to Window > Properties to open it. The artboard tool is faster than the menu route because you see your changes in real time as you adjust the numbers.

Key Takeaways

  • The Artboard tool in the left toolbar lets you select and resize your canvas by typing new dimensions or dragging the edges.
  • The Properties panel on the right shows the exact width and height in pixels, inches, or other units—change these numbers to resize when ready.
  • You can have multiple artboards in one file, and each one resizes independently.
  • If you want to fit the canvas around your artwork instead of resizing manually, use Object > Artboards > Fit to Artwork Bounds.

Resizing with the Artboard tool menu

If you prefer using menus instead of the toolbar, go to Object > Artboards > Edit Artboard. This opens the same selection mode as clicking the Artboard tool, and you can then adjust dimensions in the Properties panel or by dragging.

The menu route takes one extra step, but it's useful if you've hidden the left toolbar or prefer keyboard navigation. Once you're in edit mode, the behavior is identical to using the tool directly.

Changing units and preset sizes

The Properties panel shows your artboard dimensions in whatever unit your document uses—pixels, inches, millimeters, or points. To change units for the whole document, go to File > Document Setup and select a new unit from the dropdown. This changes how all measurements display, but doesn't resize your artboard.

Illustrator also includes preset sizes. With the Artboard tool active, look for the Presets dropdown in the Properties panel. You can choose from common sizes like Letter, A4, or Instagram post dimensions. Selecting a preset automatically resizes your artboard to those dimensions.

Fitting the canvas to your artwork

If you've drawn outside your original artboard or want the canvas to match your content exactly, use Object > Artboards > Fit to Artwork Bounds. Illustrator measures all your visible objects and resizes the artboard to contain them with a small margin.

This is faster than manually measuring and typing dimensions, especially if your artwork is irregular or you've added elements in different areas. The artboard will expand or shrink to fit, and you can always adjust it further afterward if needed.

Working with multiple artboards

Illustrator lets you have more than one artboard in a single file. Each artboard is independent—resizing one doesn't affect the others. Select the Artboard tool, then click the artboard you want to modify. Its dimensions appear in the Properties panel, and you can change them just like a single artboard.

To add a new artboard, click the plus icon in the Properties panel while the Artboard tool is active. To delete one, select it and press Delete. This setup is useful for designing multiple pages, variations, or different-sized assets in one project.

Undoing and checking your changes

If you resize your artboard and regret it, press Ctrl+Z (Windows) or Cmd+Z (Mac) to undo. Illustrator remembers your last several actions, so you can step back as far as needed.

To verify your new dimensions, keep the Properties panel open while you work. The numbers update in real time as you drag or type, so you always know the exact size. If you close the Properties panel by accident, reopen it from Window > Properties.

Frequently Asked Questions

Does changing the artboard size crop my artwork?

No. The artboard is just the boundary Illustrator uses for printing and exporting. Objects outside the artboard remain in your file and print if you tell Illustrator to include them. If you want to actually remove content outside the artboard, you must delete it manually or use the crop tool.

Can I make the artboard a different shape, like a circle?

The artboard itself must be rectangular—Illustrator doesn't support non-rectangular artboards. However, you can draw any shape you want on top of it and export just that shape. For printing or exporting, the rectangular artboard boundary is what matters.

What's the difference between artboard size and canvas size?

In Illustrator, the artboard is the canvas. There's no separate "canvas size" setting. The artboard defines what gets printed, exported, or displayed as a page. Anything outside it is still part of your file but won't print unless you change the artboard or export settings.

How do I resize the artboard to fit a specific print size?

Use the Presets dropdown in the Properties panel—it includes standard print sizes like Letter, A4, and tabloid. If your size isn't listed, type the width and height directly into the Properties panel. Make sure your document units match your intended output (inches for US print, millimeters for metric).

Can I resize multiple artboards at once?

No, you must resize each artboard individually. Select one with the Artboard tool, change its dimensions, then move to the next. If all your artboards need to be the same size, you can select one, resize it, then copy and paste it to replace the others.
