Normally, when you start to work on a new design in Canva, you choose your preferred design type, such as an Instagram Post, poster, YouTube video, etc. The type of design determines the dimensions of the workspace.
In the free version of Canva, once you choose the type and start to create it, you’re pretty much committed to that size.
But if you’re halfway through your work and decide that you want the post to be for Facebook instead of Instagram, you’re stuck. This means that you either have to start over or somehow copy from one design to the other.
In the Pro version, however, you can use the Magic Resize tool at the top left corner of the screen. With a few clicks, you can create duplicates of your creation in other sizes. In those copies, you may need to move some elements around to make them fit better, but the basic layout remains.
This is a great timesaver if you plan to post the same thing on multiple social media platforms. Another example is when you want to create multiple materials to represent the same brand, like a website header, letterheads, and presentations.
