With images, the canvas size is determined by the resolution of the file. If you’re working on a graphic design project, you’ll input your canvas’s dimensions when starting out.

The problem is, how do you change the canvas size in GIMP after you’ve started a project? Or if the image size doesn’t match the dimensions required?

Today, I’ll show you how easy it is to change your canvas size, either larger or smaller, regardless of where you are in your workflow.

How To Change the Size of Your Canvas in GIMP

Whether you’re editing an image or working on a design project, the steps are the same.

Step 1: Open or Create a New Document

Either open an image or create a new document in GIMP to get started.

Step 2: Resize the Canvas

Resizing your canvas is as simple as selecting “Canvas Size” from the Image menu.

Step 3: Adjust the Measurement

Depending on your final project’s output source, it may require measurement in pixels, inches, or something else. Make sure to select the measurement type via the drop-down menu to the right.

Step 4: Unlock the Chain Link For the Exact Size

By default, the width and height are linked together. When you input one, the other will auto-update to keep the aspect ratios intact. To input, the exact dimensions for both the width and height unlock the “chain” icon.

Step 5: Input & Adjust For the Crop

Input the dimensions into the width and height. If your new canvas size doesn’t match the image’s aspect ratio and you’re making it smaller, cropping will occur.

Observe the preview of the image to see an outline that represents the crop that will occur. Click on the preview and move the image according to change how the crop will be applied.

Once you’re done with your inputs and crop adjustments, hit the Resize button.

Pro Tip:

When increasing the canvas size, you’ll want to make sure the image resolution matches (as closely as possible) the canvas size required. Otherwise, your image will end up pixelated (soft – low quality).
