What image size should I use to design book cover? [closed]

I have got a project of Book Cover design. The client is telling me that book cover should be print ready and ready to upload on Create Space.

I know if design is in CMYK color mode, means it is print ready so no problem with this. Create Space allows only 300dpi resolution cover design so my question is;

What image size should I use to design book cover?
I am designing both front and back sides with spine.
