Open the Artboard Tool and Select Your Canvas

To change canvas size in Illustrator, you first need to access the Artboard Tool, which controls the boundaries of your working space. Click the Artboard Tool in the left toolbar — it looks like a rectangle with corner handles — or press Shift + O on your keyboard.

Once the tool is active, click on the artboard (canvas) you want to resize. The artboard will show selection handles at its corners and edges. If you have multiple artboards in your document, make sure you click the one you intend to change.

Key Takeaways

  • The Artboard Tool (Shift + O) is the primary way to resize your canvas in Illustrator, and it shows handles you can drag to change dimensions.
  • You can resize by dragging the corner or edge handles, or by entering exact width and height measurements in the Properties panel on the right.
  • The Properties panel also holds preset canvas sizes — select one to when ready match common dimensions like letter, tabloid, or custom web sizes.
  • Double-clicking the artboard name in the Artboards panel lets you rename it and access additional settings like orientation and bleed.

Resize by Dragging Handles or Entering Exact Dimensions

Once your artboard is selected, you have two ways to change its size. The quickest method is to drag the corner or edge handles outward to enlarge the canvas, or inward to shrink it. Dragging a corner handle resizes both width and height at once; dragging an edge handle changes only that dimension.

For precise measurements, look at the Properties panel on the right side of your screen. You will see fields labeled W (width) and H (height). Click into either field, type your desired measurement, and press Enter. Illustrator accepts measurements in inches, centimeters, pixels, or points — just type the number followed by the unit (for example, 8.5in for 8.5 inches).

Use Preset Sizes from the Properties Panel

The Properties panel also contains a dropdown menu with preset artboard sizes. Click the dropdown at the top of the Properties panel to see options like Letter, Tabloid, A4, A3, and web-specific sizes such as 1920 x 1080 or Instagram Post. Selecting a preset when ready resizes your artboard to those dimensions.

This is useful if you are working on a project with a standard size requirement — for instance, if you need to match a specific print format or social media dimension. The preset menu saves you from having to look up and type measurements yourself.

Change Orientation Between Portrait and Landscape

In the Properties panel, you will see two orientation buttons next to the width and height fields — one shows a vertical rectangle (portrait) and one shows a horizontal rectangle (landscape). Click either button to flip your artboard between these orientations. The width and height values swap automatically.

This is faster than manually changing the numbers if you straightforward need to rotate your canvas orientation. The button approach is especially helpful when you are switching between a vertical design (like a mobile app mockup) and a horizontal one (like a landscape poster).

Adjust Position and Bleed Settings

If you need to move your artboard to a different location on the canvas, the Properties panel shows X and Y coordinates. Changing these values shifts where the artboard sits in your document space without changing its size. This is useful if you have multiple artboards and want to reposition one.

For print projects, you may also need to set bleed — the extra space beyond the artboard edge that accounts for cutting. Double-click the artboard name in the Artboards panel (Window > Artboards if it is not visible) to open the Artboard Options dialog. Here you can enter bleed values on all four sides. Bleed is measured in the same units as your artboard and is typically 0.125 inches for standard print work.

Delete or Add Artboards if You Need Multiple Canvases

If you have more than one artboard and want to remove one, select it with the Artboard Tool and press Delete. The artboard disappears, but your artwork on other artboards remains untouched.

To add a new artboard, click the plus icon in the Artboards panel, or right-click in the Artboards panel and select New Artboard. You can then resize and position this new artboard the same way as any other. This is helpful when you are designing multiple versions of the same project — for example, different page layouts or social media post sizes — all in one file.

Frequently Asked Questions

Can I resize the canvas without affecting my artwork?

Yes. Resizing the artboard changes only the visible canvas boundary, not your artwork itself. If your design extends beyond the new artboard edge, it will be hidden from view but not deleted. You can always enlarge the artboard again to see it.

What is the difference between artboard size and canvas size?

In Illustrator, the artboard is the canvas — they are the same thing. The artboard defines what will print or export. The larger canvas you see in the background is just your working area; only content on the artboard itself is included in output.

How do I resize all artboards at once?

You cannot resize all artboards simultaneously with a single command. You must select each artboard with the Artboard Tool and resize it individually. If you need many artboards to be the same size, resize one, then use the Properties panel to copy its dimensions and explore them to the others by hand.

Can I set a custom artboard size that is not in the presets?

Yes. straightforward type your own width and height values directly into the W and H fields in the Properties panel. Illustrator accepts any measurement you enter, so you can create artboards of any custom dimension you need.
