There are three different ways to resize an image with Gimp. Below are details about the three methods, and examples of what they do.

Scale image

Scaling refers to the process by which and image is enlarged or reduced by a given parameter. To scale an image, click the arrow menu in the upper left corner of the Gimp image window and select the Image menu. Then click "Scale Image..." to open the Scale Image Dialog window.

You can choose whether to change your image by pixels or percentage, and whether to keep the ratio the same (by clicking on the chain to the right of the ratio entries). Below are some examples of scaling operations.

Original Image	Scaled to 150% ratio locked	Scaled to 50% ratio unlocked

Crop image

To crop an image means to cut out the unwanted parts of the image. The crop tool allows you to select a rectangular area of the image and cut the rest away. An example is below.

Original Image	Image Cropped

Adjust Canvas

The Adjust canvas feature is the least useful feature for changing the image size, but there are times that you might want to use it. In essence, it allows you to add more space to your image without distorting the images you already have.

Original Image	More Canvas

Note: Unless you are using layers to manage your document, you will probably find this option pretty useless. If you're only using one layer, you won't be able to draw on the new area that you've created without scaling your image to fit the new area.
