Understanding Canvas Size

Before we delve into the process of changing canvas size in Krita, let’s first clarify what it means and why it’s important. The canvas size refers to the dimensions of your digital workspace, representing the area where you can create your artwork. It determines the width, height, and aspect ratio of your canvas, playing a crucial role in various aspects of digital art creation.

Importance of Canvas Size

The canvas size is like the foundation of your artwork, providing the framework for your creative expression. It affects the overall composition, print and display options, and compatibility with different devices and platforms.

A well-chosen canvas size ensures the best possible outcome, whether you’re printing your artwork or showcasing it digitally. It allows you to maintain the desired level of detail, ensures the correct proportions, and enhances the overall visual impact of your artwork.

Canvas size also plays a significant role in adapting your artwork for different platforms, such as social media or websites. Each platform may have specific requirements or display limitations, and understanding how to change canvas size will enable you to optimize your artwork accordingly.

Now that we’ve established the importance of canvas size, let’s move on to the step-by-step tutorial on how to change canvas size in Krita.

Changing Canvas Size in Krita: Step by Step Tutorial

Now that we have a solid understanding of the importance of canvas size, let’s explore how to change it in Krita. Follow the step-by-step tutorial below to resize your canvas according to your desired dimensions:

Step 1: Open your artwork

The first step is to open the artwork you wish to resize in Krita. You can either create a new document or open an existing one. To create a new document, go to the “File” menu, select “New,” and specify the dimensions for your canvas. If you’re opening an existing document, go to the “File” menu and select “Open.”

Step 2: Access the “Canvas” settings

Once your artwork is open, navigate to the top menu and click on “Image.” From the dropdown menu, select “Canvas Size” or “Resize Canvas” to access the canvas settings. Alternatively, you can use the shortcut keys Ctrl+Alt+C.

Step 3: Adjust the canvas dimensions

In the canvas settings window, you will see options to modify the width, height, and resolution of your canvas. Enter the desired values for each parameter:


The width determines the horizontal dimension of your canvas. You can either enter a specific value or use the up and down arrows to adjust it incrementally. Krita supports various units of measurement, such as pixels, inches, centimeters, or millimeters.


The height determines the vertical dimension of your canvas. Similar to the width, you can input a specific value or use the arrows to make adjustments. Ensure that the units of measurement are consistent with those used for the width.


The resolution refers to the number of pixels per unit of length in your artwork. It affects the image quality and pixel density. Higher resolutions generally result in sharper and more detailed images, while lower resolutions may appear more pixelated or less refined. Choose a resolution that suits your specific needs, considering factors such as printing requirements or display preferences.

Aspect Ratio

The aspect ratio represents the proportional relationship between the width and height of your canvas. It ensures that your artwork retains the original shape and proportions when changing the dimensions. Krita provides an option to lock the aspect ratio, so any modifications to the width or height will be proportionally applied.

Step 4: Choose the resizing method

Krita offers different methods for resizing your canvas. Depending on your specific requirements, you can select either “Crop to result” or “Scale image.”

Crop to Result

If you choose “Crop to result,” Krita will automatically remove any excess canvas areas that are not part of your artwork. This option is useful when you want to focus on a specific area of your artwork and eliminate unnecessary background or empty spaces.

Scale Image

On the other hand, if you select “Scale image,” Krita will resize the entire artwork, including the canvas and its contents. This option is ideal when you want to maintain the overall composition and proportions of your artwork while changing the canvas size.

Step 5: Preview and Confirm

Before applying the changes, Krita provides a preview of the resized canvas. This allows you to assess the modifications and ensure they align with your desired outcome. Take a moment to review the preview, paying attention to the composition, proportions, and overall impact of the resized canvas.

If you’re satisfied with the preview, click on “OK” to confirm the new canvas size and apply the changes. If you want to make further adjustments, you can modify the dimensions or resolution in the canvas settings and preview the changes again before finalizing them.

Step 6: Adapt Your Artwork

After resizing the canvas, you may need to readjust your artwork to fit the new dimensions. Depending on the extent of the change, your artwork elements might become distorted or positioned incorrectly.

Use Krita’s transformation tools, such as the “Move,” “Scale,” or “Rotate,” to modify and position your elements accordingly. You can select individual layers or objects and apply the necessary transformations to ensure they align with the resized canvas.

Take this opportunity to refine your artwork, make any necessary tweaks, and ensure that it looks its best in the new canvas size.

Step 7: Save Your Resized Artwork

Finally, once you are satisfied with the changes, save your resized artwork using the “Save” or “Save As” options in the “File” menu. It is recommended to save it under a new name to preserve the original version.

Choosing an appropriate file format is crucial. Consider factors such as image quality, compatibility, and future editing requirements. Popular file formats for saving digital artwork include JPEG, PNG, and TIFF.

By following these step-by-step instructions, you can easily change the canvas size in Krita to fit your artistic vision.

Canvas Size Options

When changing the canvas size in Krita, you have several options available to customize your digital workspace:


The width option allows you to adjust the horizontal dimension of your canvas. You can increase or decrease the width depending on your requirements. Keep in mind that modifying the width without maintaining the aspect ratio may result in stretched or distorted artwork.


The height option, similar to the width, allows you to modify the vertical dimension of your canvas. It enables you to expand or shrink the canvas vertically, giving you more or less space to work with.


The resolution option controls the image quality and pixel density of your artwork. Higher resolutions result in sharper and more detailed images, while lower resolutions may appear more pixelated. Consider the intended use of your artwork, such as printing or digital display, when selecting the resolution.

Aspect Ratio

The aspect ratio ensures that the proportions of your artwork remain consistent when changing the canvas dimensions. It maintains the original shape and prevents distortion. By locking the aspect ratio, any adjustments made to the width or height will be proportionally applied, preserving the integrity of your artwork.

Consider experimenting with different canvas sizes and aspect ratios to explore new creative possibilities and determine the best fit for your specific artistic vision.
