resize an image in the gimp

Gimp is one of the most popular free graphics editors for Linux and Windows. If Windows still has Photoshop, then for Linux Gimp is the most functional when it comes to editing photos or images. Sometimes it becomes necessary to change the size of the image, for example, increase or decrease it.

In this short article, we’ll look at how to resize an image in Gimp, as well as how to resize the artboard and objects in the image.

Change the scale of the work area

If you do not need to change the image itself, but only consider some small object or, on the contrary, look at the image from a distance, you can scale the working window. To do this, hold down the Ctrl button and roll the mouse wheel up to zoom in and down to zoom out.

This setting only affects the interface, no changes are applied to the image itself. The current scale of the interface can be viewed in the menu View -> Scale… For example, in this image, the scale is 150%. Other standard options can also be selected.

Resizing canvas in Gimp

The canvas is the area in which you are working with the image. If you created a new image, painted something on it, and then realized that the current size of the canvas is not enough for you, you can increase it. To do this, open the menu Image -> Canvas size… Here you can select a new size.

If it is necessary for the size to change in proportion to the current image, concatenate the length and width using a special switch. This must be done before you change the size.

Also pay attention to point Resize layers… By default, the layers will remain as they were. This means that you cannot paint on the new area. For it, you will need to create a new layer or expand existing ones. To expand the size of the layers to the size of the new canvas, select All layers… If you have not done this, you can increase the size of the layer later, to do this, on the right panel, go to the tab Layers, click on the desired layer and select Layer to Image Size.

Resizing an image in the Gimp

Most often, you need to resize the image itself. This is done in the same way as resizing the canvas, only it is much easier, because you don’t need to think about layers here, they will be automatically scaled. Open the menu Image -> Resize the image. Here select whether the size should be resized proportionally, and then select a new size.

After pressing the button Change the image will be scaled. Now you know how to resize a Gimp image.

Resizing objects in an image

The previous method will only work for the whole image. If you want to scale only some part of the image, then you need to use the tool Scaling… First select a tool Rectangular selection and select the area you want.

Then activate the tool Scaling… If it is not in the panel on the left, you can find it in the menu Instruments -> Transformation -> Change… Next, click on the selected area. The scaling window will open. You can manually specify the size or drag the squares on the sides of the image. Using the square in the center, you can move it.

When everything is ready, press the button Change… This is how you can resize the selected Gimp image.


In this short article, we looked at how to resize an image in the Gimp. As you can see, it is not difficult at all and now you know not only how to resize the entire image, but also the size of layers, as well as arbitrary areas in the image.
