The fastest way to change canvas size in Illustrator

Open your document, then go to File > Document Setup. In the dialog that opens, you'll see fields for width and height under the artboard section. Change these numbers to your new dimensions, choose your unit of measurement (inches, pixels, centimeters, or points), and click OK. The canvas resizes immediately.

If you're working with multiple artboards, this method changes all of them at once. If you need to resize just one artboard, use the Artboard tool instead: select it from the toolbar on the left (it looks like a rectangle with corner marks), click the artboard you want to change, then adjust the width and height in the properties panel on the right side of your screen.

Key Takeaways

  • Document Setup resizes all artboards in your file at once, while the Artboard tool lets you resize individual artboards separately.
  • You can set exact dimensions by typing numbers into the width and height fields, or drag the artboard edges with the Artboard tool to resize visually.
  • The anchor point position matters: changing it determines which direction the artboard expands or shrinks from.
  • Resizing the canvas does not automatically scale your artwork — objects stay their original size unless you manually scale them.

Using the Artboard tool for single artboards

The Artboard tool gives you more control when you're working with one artboard at a time. Press Shift + O to activate it, or click the Artboard tool in the toolbar. Once it's active, click the artboard you want to resize and you'll see handles at the corners and edges.

Drag any corner handle to resize both dimensions at once, or drag an edge handle to change just the width or height. If you want exact numbers instead of dragging, the properties panel on the right shows width and height fields — type your new dimensions there. You can also change the position of the artboard by adjusting the X and Y coordinates in that same panel.

Understanding anchor points and resize direction

When you resize an artboard, the anchor point determines which direction it grows or shrinks. The anchor point is a small square in the properties panel that shows nine positions — the center and the four corners and four edges of the artboard.

If your anchor is set to the top-left corner and you increase the width, the artboard expands to the right. If it's set to the center and you increase the width, the artboard expands equally in both directions. Click the position you want in the anchor diagram before you change your dimensions, and the resize will happen from that point outward.

What happens to your artwork when you resize

Changing the canvas size does not move or scale the objects you've drawn. If your artwork was positioned near the edge of the old canvas and you make the canvas smaller, parts of your artwork may now sit outside the visible artboard area. You won't lose the artwork — it's still there in your file — but it won't print or export unless you move it back inside the artboard boundaries.

If you want your artwork to scale along with the canvas, you need to select all your objects first (press Ctrl + A on Windows or Command + A on Mac), then manually scale them using the Scale tool or the Transform panel. The canvas resize itself never touches your artwork's size.

Resizing multiple artboards at different sizes

If you have several artboards and need them to be different sizes from each other, use the Artboard tool on each one individually. Select the Artboard tool, click the first artboard, change its dimensions in the properties panel, then click the next artboard and repeat. This is slower than Document Setup but gives you complete control over each artboard's final size.

You can also arrange artboards in a grid by going to File > Document Setup, clicking the Edit Artboards button, and choosing a grid layout. This is useful if you're designing multiple pages or variations that need to be organized, though it applies the same size to all artboards in the grid.

Exporting and printing at your new canvas size

Once you've resized your artboard, your export and print settings will use the new dimensions by default. When you export (File > Export), Illustrator shows you a preview of what will be included — anything outside the artboard boundaries won't be part of the export unless you manually adjust the export settings to include hidden artwork.

If you're printing, go to File > Print and check the preview there as well. The printer will output only what's inside the artboard area. If your artwork extends beyond the artboard and you want it included, either move the artwork back inside the boundaries or change your export/print settings to include the full document rather than just the artboard.

Frequently Asked Questions

Can I resize the canvas without moving my artwork?

Yes. Resizing the canvas never moves your artwork automatically. If parts of your artwork end up outside the new artboard boundaries, they stay where they are — they just won't be visible or exported. Use the Selection tool to move artwork back inside if needed.

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

In Illustrator, the artboard is the canvas. They're the same thing. The artboard defines what will print or export. Anything outside the artboard boundary exists in your file but won't be included in output unless you change your export settings.

How do I resize just one artboard when I have multiple?

Use the Artboard tool (Shift + O), click the specific artboard you want to change, then adjust its width and height in the properties panel. Document Setup changes all artboards at once, so the Artboard tool is your option for individual control.

Does resizing the canvas scale my text and objects?

No. Resizing the artboard changes only the boundary of what will print or export. Your text, shapes, and images stay their original size. If you want everything to scale proportionally with the new canvas size, select all objects first and use the Scale tool manually.
