How to Change Canva Slide Size

Canva presentations start in 16 by 9 using 1920 by 1080 pixels, which is standard and modern. If you need a different aspect ratio like 4 by 3, 1 by 1, or 9 by 16 vertical, you can switch sizes easily. Canva handles this well and keeps your work intact.
I like that the result looks close to the original version. Animations are intact, which is a big plus. The process is quick and easy to repeat.

How to Change Canva Slide Size
Open your document in Canva.

Click Resize, then choose Magic Switch.

Click Select all under the Resize section.

Choose a preset size or type a custom size in pixels.

For this example I picked Instagram Post at 1080 by 1080 for a square 1 by 1.

Click Continue to generate the preview.

Preview before you Change Canva Slide Size

Canva will create a preview that shows how the design will look after the change. The layout stays familiar and close to the original. Check that key elements and animations still look right.
Copy instead of overwriting when you Change Canva Slide Size
When you are happy with the preview, click Copy and resize. I do not recommend using the single Resize option because it overwrites the original. Always keep a backup so you can return to the original design if needed.

Wait for the process to finish, then click Open Instagram Post. This opens the new copy at the new aspect ratio. It is fast and reliable.

After you Change Canva Slide Size
The new document opens in the new aspect ratio, for example from rectangular to square. I usually find it is 80 to 90 percent similar to the original. A few small adjustments may be needed to perfect spacing and alignment.
