Change your artboard size in the Artboards panel or by double-clicking the artboard edge

The fastest way to change document size in Illustrator is to use the Artboards panel. Open it from the Window menu, select your artboard, and enter new width and height values in the panel on the right. You can also double-click the artboard edge itself and drag to resize it directly on the canvas. A third option is the Artboard tool in the left toolbar — select it, click your artboard, and the dimensions appear in the top toolbar where you can type exact measurements.

The method you choose depends on whether you want precision or speed. Typing numbers gives you exact dimensions. Dragging gives you visual feedback. The Artboards panel works best if you are managing multiple artboards at once, since you can see and adjust them all in one place.

Key Takeaways

  • The Artboards panel (Window > Artboards) shows all your artboards and lets you change width and height by typing new numbers.
  • The Artboard tool in the left toolbar lets you select an artboard and type exact dimensions in the top toolbar, or drag the edges to resize visually.
  • Double-clicking the artboard boundary on the canvas lets you drag to resize without opening any panel.
  • Changing artboard size does not automatically resize objects on it — your content stays the same size unless you manually scale it.

Using the Artboards panel for precise measurements

Go to Window > Artboards to open the Artboards panel on the right side of your screen. You will see a list of all artboards in your document. Click the one you want to resize. Below the list, you will see fields for X, Y, W (width), and H (height). The X and Y values control where the artboard sits on the canvas; W and H control its size.

Click in the W field and type your new width. Press Tab to move to the H field and type your new height. Press Enter to explore the change. If you are working in inches, type the number followed by "in" — for example, 8.5in. For centimeters, type "cm". Illustrator converts automatically. This method is most useful when you know the exact dimensions you need, such as when you are preparing a file for print or web export.

Using the Artboard tool from the toolbar

Click the Artboard tool in the left toolbar — it looks like a rectangle with corner marks. Click once on the artboard you want to resize. The artboard outline turns blue, and the top toolbar changes to show artboard options. You will see fields for W and H on the left side of the top toolbar. Type your new width and height values directly into these fields and press Enter.

The Artboard tool also shows the artboard's current dimensions in the top toolbar, so you can see what you are working with before you change anything. If you prefer to resize by dragging instead of typing, keep the Artboard tool selected, position your cursor over one of the corner or edge handles on the artboard boundary, and drag to the new size. Corner handles resize both dimensions at once; edge handles resize only the dimension they are on.

Resizing by dragging the artboard edge directly

Double-click anywhere on the artboard boundary — the blue line that marks the edge of your document. The artboard enters edit mode and the corners and edges show small square handles. Click and drag any handle to resize. Dragging a corner handle resizes both width and height together. Dragging an edge handle resizes only that dimension.

This method is the quickest if you do not need exact measurements and just want to make the artboard larger or smaller visually. It is also useful for fitting an artboard around existing content — resize until the artboard boundary matches what you want to keep. When you are done, click elsewhere on the canvas to exit edit mode.

What happens to your content when you resize

Changing the artboard size does not automatically scale or move the objects you have drawn on it. Your shapes, text, and images stay exactly where they are and at their original size. If you make the artboard smaller, content that was inside may now extend beyond the artboard boundary — it is still there, just not visible when you export or print.

If you want to resize your content along with the artboard, you must do that separately. Select all your objects (Ctrl+A or Cmd+A), then use the Scale tool or the Transform panel to resize them to match your new artboard dimensions. Alternatively, you can use Object > Artboards > Fit to Selected Art to automatically resize the artboard to match the size of selected objects.

Changing document size vs. artboard size

In Illustrator, "document size" and "artboard size" mean the same thing in most workflows. The artboard is what prints or exports. If you want to change the overall canvas size — the space where you can draw — you are changing the artboard. There is no separate "document size" setting the way there is in some other programs.

If you have multiple artboards and want to change only one, use the Artboards panel or Artboard tool to select that specific artboard before resizing. If you want to resize all artboards at once, you can select multiple artboards in the Artboards panel by holding Ctrl (or Cmd on Mac) and clicking each one, then change the W and H values — the change applies to all selected artboards.

Common sizes and presets

Illustrator does not have a built-in preset menu for common sizes, but you can type standard dimensions directly into the W and H fields. Common print sizes include 8.5in × 11in (letter), 11in × 17in (tabloid), and 4in × 6in (postcard). For web, common sizes are 1920px × 1080px (full HD), 1200px × 630px (social media), and 800px × 600px (older standard).

When you type a number without a unit, Illustrator assumes points by default. To use a different unit, type it after the number: "in" for inches, "cm" for centimeters, "mm" for millimeters, "px" for pixels, or "pt" for points. You can also change the default unit in Edit > Preferences > Units (Windows) or Illustrator > Preferences > Units (Mac), but typing the unit directly is faster if you only need it once.

Frequently Asked Questions

Can I resize an artboard without affecting the objects on it?

Yes. Resizing the artboard does not move or scale objects. They stay in place. If objects extend beyond the new artboard boundary, they are still there but will not print or export unless you manually move them back inside or resize the artboard again.

How do I resize multiple artboards to the same size at once?

Open the Artboards panel, hold Ctrl (or Cmd on Mac), and click each artboard you want to select. With multiple artboards selected, type new W and H values in the panel. The change applies to all selected artboards at the same time.

What if I want the artboard to fit around my artwork automatically?

Select all the objects you want to keep, then go to Object > Artboards > Fit to Selected Art. Illustrator resizes the artboard to the smallest rectangle that contains all selected objects, with a small margin.

Can I change the artboard size using the File menu?

No. The File menu does not have an artboard size option. Use the Artboards panel, the Artboard tool, or double-click the artboard edge. The Artboards panel is the most direct route.

Does changing artboard size affect export settings?

No. The artboard size determines what area exports, but export settings like file format, color mode, and resolution are separate. Change those in the export dialog when you save the file.
