The maximum print area size for Print Then Cut projects is 9.25" x 6.75". If your printable image exceeds these dimensions, Design Space will display a warning message to reduce the image size to less than 9.25" x 6.75."
I don't want to print; I just want to cut
When Design Space tells you that the "Printable Image is too large," this means that the image you are trying to cut is set to Print Then Cut, but the image exceeds the Print Then Cut size limitations. If you do not wish to Print Then Cut, and would rather cut only, you can easily change your image's line type from Print to Cut. Follow the instructions found here to change the image line type.
Note: Cut images do not retain any internal patterns or colors. When you change an image from a Print Then Cut image to a Cut image, internal patterns and colors will disappear.
If your image does not have the shape you wish it to have after changing it to a Cut image, upload the image again and proceed through the clean-up steps. This time, be sure to use the Preview option in the cleaning step. This option shows you the current cut paths of your uploaded image. You may need to erase some of the background or areas inside the image to achieve the desired shape and cut result.
When you have finished cleaning the image, proceed to the next screen and select "Save as a Cut image" before saving the image to your library.
