How can you change the canvas size in Photoshop?

To change the canvas size in Photoshop, you navigate to the "Image" menu and select "Canvas Size." This method specifically adjusts the dimensions of the canvas, which is the area surrounding your artwork. It allows you to add or reduce space around your image without affecting its size. This is particularly useful when you want to extend your working area or fit your artwork into a specific layout.

Choosing "Canvas Size" lets you input new dimensions for the canvas in various units and offers options for anchor points, determining how the existing content will be positioned relative to the new canvas size.

Other methods mentioned, such as resizing the image directly or using transformation tools, focus on changing the size of the image itself rather than the canvas. This distinction is important for maintaining the integrity of your artwork while adjusting the working space around it.
