How to Resize An Image in GIMP

BY Sourav



Resizing an image to the desired size is a common practice before uploading it on social media or printing it. GIMP (GNU Image Manipulation Program) is an excellent image editor to give photos a retouch. It has all the necessary editing tools that even a beginner can easily understand.

When you want to resize an image in Gimp, there’re two straightforward ways to do that. You can resize it either numerically using Scale Image or manually using the Scale Tool. Let’s learn about them one by one.

How to Resize an Image Using Scale Image in Gimp

To resize an image in Gimp, the easiest way is to do it using the Scale Image option. This allows you to insert your preferred ratio in numerics (percentage, pixels, mm, or inches) to get the best resolution in a perfect size.

Here’s the step-by-step guide to do it:

1. With Gimp open, navigate to File> Open and choose an image.

2. Click Image> Scale Image.

3. A Scale Image dialog box will show up.

4. To check your image size in percent, inches, or other values, use the drop-down beside the value.

5. Enter the new size by setting the width and height.

6. Click Scale to apply the changes.

How to Resize an Image with Gimp Scale Tool

This method is helpful when you don’t understand what ratio or size will be perfect for the image. 

Gimp’s in-built tool called Scale Tool that’s used for scaling individual layers of an image. Keep in mind that even if your image has multiple layers, Gimp’s Scale Tool will scale only individual layers instead of the whole image.

In short, when resizing an image with multiple players with this method, the changes will only apply to one layer.

  1. Select the Scale Tool from the menu list in the top-left corner. Alternatively, select Shift + S to open it quickly.
  2. Click on the image and the square scaling handles will appear in the corner and side of it. You’ll also see a dialogue box to adjust the image size numerically similar to the previous method.
  3. Click and drag the scaling handles to resize the image.

When you resize the image, you’ll notice the image will scale proportionately by default. It means the aspect ratio will be locked without changing the height and width.

So, while resizing an image with this process, hold the shift key while clicking and dragging. So, the aspect ratio lock will be released and you can adjust the image size.

Once you’re done, press enter to save and apply the changes.

  1. Resize the canvas to fit the image size using the Crop to Content feature.
  2. Select Image > Crop to Content and the canvas will be the same size as the new image. 

That’s all. Gimp is an amazing image editing software to resize any image. These are the two methods that you can use to resize an image to your preferred size.
