What cover formats does KDP Builder generate?

KDP Builder generates ebook covers (front only, 1600×2560 px), paperback full wraparound covers (front + spine + back, sized to your trim and page count), and hardcover/case laminate covers with 0.0625" bleed per KDP specifications.

Do I need design experience or Photoshop?

Not at all. You describe your book's genre, mood, and key elements in plain text. Our AI generates multiple professional cover concepts in seconds. You pick the one you like, and we deliver a print-ready file.

How does spine width get calculated?

You enter your page count and paper type (white or cream). KDP Builder automatically calculates the correct spine width using Amazon's formula and positions your title and author name on the spine.

Can I use my own images or branding?

Currently the AI generates original artwork based on your description. You can iterate on the design by refining your prompt until the cover matches your vision. Custom image upload is on our roadmap.

What file format do I receive?

You receive a high-resolution PNG or PDF file that meets Amazon KDP's upload specifications, including proper bleed, margins, and DPI requirements.

How much does it cost?

New accounts receive 75 free credits. An ebook cover costs 14 credits and a full print wrap (front, spine, back) costs 16. Additional credits start at just a few dollars.

Can I generate covers for multiple books?

Absolutely. You can create covers for as many books as you want. Many authors use KDP Builder to create cohesive cover sets for entire book series, maintaining consistent branding across titles.
