The fastest way to resize your canvas

Open the File menu and select Document Setup. In the dialog box that appears, you will see fields for Width and Height under the Artboard section. Change these numbers to your new dimensions, then click OK. Your canvas resizes when ready, and any artwork positioned within the new boundaries stays in place.

If you are working with multiple artboards, this method changes only the active artboard — the one you have selected. You can tell which artboard is active by the thick black border around it on your canvas.

Key Takeaways

  • Document Setup (File menu) is the standard way to change artboard dimensions for a single canvas.
  • You can set width and height in pixels, inches, centimeters, or other units by typing the unit abbreviation after the number.
  • The Artboard tool lets you resize by dragging corners directly on the canvas instead of typing numbers.
  • Changing canvas size does not automatically scale your artwork — it only changes the boundary of what will print or export.

Using the Artboard tool to resize by dragging

Select the Artboard tool from the left toolbar (it looks like a rectangle with corner handles), or press Shift + O. Click on the artboard you want to resize. Small squares appear at the corners and edges of the artboard boundary.

Drag any corner handle outward to enlarge the canvas or inward to shrink it. Drag an edge handle to change only the width or height. As you drag, Illustrator displays the new dimensions in a tooltip. Release the mouse when you reach the size you need.

This method is faster if you want to resize by eye rather than enter exact numbers. It also works well when you need to adjust the canvas to fit artwork that extends beyond the current boundary.

Changing units and entering precise dimensions

In Document Setup, the width and height fields accept any unit of measurement. Type the number followed by the unit abbreviation: in for inches, cm for centimeters, mm for millimeters, pt for points, or px for pixels. For example, typing 8.5in sets the width to 8.5 inches.

If you do not type a unit, Illustrator uses whatever unit is set as the default in your preferences. You can change the default by going to Illustrator (Mac) or Edit (Windows) > Preferences > Units, then selecting your preferred measurement system.

Moving artwork when you resize the canvas

Changing canvas size does not move your artwork automatically. If you shrink the canvas and your artwork extends beyond the new boundary, that artwork will be hidden when you print or export — but it remains in the file and can be moved back into view.

To reposition artwork after resizing, use the Selection tool (press V) to click and drag objects to where you want them. If you need to see what lies outside the current canvas, zoom out or use the View menu to fit the entire artboard in your window.

Resizing multiple artboards at once

If your document contains several artboards and you want them all to be the same size, select the Artboard tool and then hold Shift while clicking each artboard you want to resize. All selected artboards will have selection handles around them.

Now drag a corner or edge handle. All selected artboards resize together, maintaining their relative positions. This is useful when you are setting up a template with consistent canvas sizes across multiple pages or variations.

Setting canvas size for print or web export

The artboard size determines what gets printed or exported as a single file. If you are preparing artwork for print, set your canvas to match your paper size — for example, 8.5 by 11 inches for a standard letter page. For web graphics, use pixel dimensions like 1920 by 1080 for a banner or 1000 by 1000 for a square social media image.

You can also set the artboard orientation (portrait or landscape) in Document Setup by clicking the orientation buttons next to the width and height fields. This is faster than manually swapping the two numbers.

Frequently Asked Questions

Does changing canvas size scale my artwork?

No. Changing the artboard size only changes the boundary of what will print or export. Your artwork stays the same size. If you want to scale the artwork itself, use the Scale tool or the Transform panel instead.

Can I undo a canvas resize?

Yes. Press Ctrl + Z (Windows) or Command + Z (Mac) when ready after resizing. You can also go to Edit > Undo Document Setup to revert the change.

What happens to artwork outside the canvas boundary?

It remains in your file but will not print or export unless you expand the canvas again or move the artwork back inside the boundary. You can always see it by zooming out or using View > Fit All in Window.

How do I resize the canvas to fit all my artwork?

Go to File > Document Setup, then click the button labeled Edit Artboards. Select Fit to Artwork Bounds from the menu. Illustrator automatically resizes the artboard to the smallest rectangle that contains all your artwork.

Can I have different canvas sizes for different artboards in the same file?

Yes. Select the Artboard tool, click the artboard you want to change, and resize it independently. Each artboard can have its own dimensions. This is useful when you are creating multiple designs at different sizes in a single document.
