Canva custom size workflow
Calculate the KDP cover size, then create a Canva design with that full width and height in inches. Arrange the left side as back cover, the center as spine, and the right side as front cover.
If you already designed only the front cover, create a new full-wrap document instead of stretching the front design across the whole file.
Canva export caution
Export settings, compression, and PDF options can affect upload quality. Review the exported file size and verify in KDP Previewer.

FAQ
Should I make a separate front cover in Canva?
For paperback upload, KDP needs a full wrap cover. A front-cover-only design is useful as source artwork but not the final cover file.
What unit should I use?
Use inches for the easiest match with KDP cover dimensions.
