Hi PH 👋 I built this because the part of cover design that actually gets rejected by KDP is not the artwork — it is the maths. Spine width changes with page count and paper stock, and a stretched front cover on a 120-page book looks wrong in the 3D preview buyers see.
So CoverNice takes your book description, gives you five directions you can edit, then renders the cover onto the real wrap: spine computed from page count + paper, bleed and safe area applied, 300 dpi PDF out, plus a 1600x2560 eBook cover.
The spine width calculator is free and needs no account — use it even if you design in Canva or InDesign: https://covernice.com/kdp-cover-...
Happy to answer anything about KDP print specs. What trim sizes are you publishing in?
