How to Change Canvas Size in Photoshop CS5: A Step-by-Step Guide

Changing the canvas size in Photoshop CS5 is a straightforward process that can be done in a few simple steps. First, open the image in Photoshop and navigate to the Image menu at the top of the screen. Then, select Canvas Size from the dropdown menu. From there, you can adjust the width and height of the canvas to your desired dimensions. Once you’ve made your changes, click OK to apply them, and voila! You’ve successfully changed the canvas size.

After you’ve changed the canvas size, you’ll notice that your image may have more or less space around it, depending on whether you increased or decreased the canvas size. This additional space can be filled with a background color or left transparent if you’re working with layers.


Ever been in a situation where the dimensions of your digital canvas just didn’t cut it? Whether you’re a graphic designer, a digital artist, or just someone looking to print a photo in a size that doesn’t match the original aspect ratio, knowing how to change the canvas size in Photoshop CS5 is an essential skill. The canvas is essentially the workspace that contains your image, and altering its size can be crucial for various projects. Maybe you need to add some extra space for text, or perhaps you’re looking to create a collage where the pieces don’t quite fit together on the default canvas. Whatever the reason, Photoshop makes it easy to customize your workspace to fit your needs.

And while the term ‘canvas size’ might sound a bit technical – worry not! It’s actually a breeze once you get the hang of it. Plus, mastering this tool opens a world of possibilities in terms of layout and design flexibility. Whether you’re a seasoned professional or a Photoshop newbie, this skill is bound to come in handy. Let’s dive into how to change canvas size in Photoshop CS5 so you can start creating without constraints.

Step by Step Tutorial: How to Change Canvas Size in Photoshop CS5

Before we begin, understand that changing the canvas size is different from changing the image size. The former alters the workspace area around the image, while the latter changes the dimensions of the image itself.

Step 1: Open the Image

First things first, open the image in Photoshop CS5.

Once you’ve opened the image, make sure it’s the active window if you have multiple projects open. This ensures that the changes you make will only affect the image you’re intending to work on.

Step 2: Navigate to the Canvas Size Option

Go to the Image menu and select Canvas Size.

The Image menu is located at the top of the Photoshop interface. Once you click it, a dropdown menu will appear with various options. Canvas Size is typically towards the bottom of this list.

Step 3: Adjust the Canvas Size

In the Canvas Size dialog box, enter the new dimensions for your canvas.

Here you can specify the exact width and height you want the canvas to be. You can also choose the measurement units that work best for you – pixels, inches, centimeters, etc. There’s a handy ‘anchor’ diagram that lets you decide where the image should sit on the new canvas.

Step 4: Apply the Changes

After setting your dimensions, click OK to apply the new canvas size.

Your image will now have a canvas that matches the dimensions you entered. If you made the canvas larger, you’ll see additional space around the image. If you made it smaller, the image might be cropped.


FlexibilityChanging the canvas size allows for more creative flexibility, such as adding borders or additional elements to your design.
CustomizationIt enables you to customize the print size of your image without altering the original image dimensions.
Non-DestructiveThis process is non-destructive, meaning you can always undo the changes or adjust the size again without loss of image quality.


Possible CroppingReducing the canvas size can lead to parts of the image being cropped out if not done carefully.
Unused SpaceIncreasing the canvas size might introduce unnecessary space that needs to be manually filled or cropped out.
Learning CurveFor beginners, the various options and settings within the Canvas Size dialog box can be a bit overwhelming at first.

Additional Information

When changing the canvas size in Photoshop CS5, it’s important to maintain awareness of your project’s needs. If you only need to reframe or crop an image, the Crop tool might be a better option. However, if you need to add space around an image for design purposes, changing the canvas size is the way to go.

Remember that increasing the canvas size might leave you with blank areas that need to be filled. These can be filled with color, patterns, or even by extending elements of your image using various Photoshop tools like the Clone Stamp or the Content-Aware Fill.

Also, when working with layers, it’s important to note that changing the canvas size won’t affect the size of individual layers. If you’re working on a complex project with multiple layers, be sure to lock the proportions or link the layers you want to keep together.

One last tip: always save a copy of your original image before making changes to the canvas size. This will ensure that you have the original to fall back on if needed.


  1. Open the image in Photoshop CS5.
