KDP Publishing EASY 3 min read

How long does a KDP cover update really take?

“I just uploaded a new cover for my paperback on KDP, hoping to boost sales. The page says it went through review in about 72 hours, but now my 'Look Inside' preview is still showing the old cover after a week. I expected everything to update at once. How much longer do I need to wait, and is this normal?”

A The answer · Cover Maker studio · Updated August 19, 2026

Swapping out your cover is often the single best move for a stagnant book. On KDP, it’s a straightforward, free process that doesn’t disrupt your book’s vital stats. The real hurdles for most authors are the waiting periods and a few specific, easy-to-overlook rules.

What Stays the Same After You Swap

All the crucial elements of your book’s listing remain intact. Your ASIN, all accumulated reviews, your sales rank, and the book’s URL are permanent. Think of a cover update as simply replacing a file, not re-publishing the entire work. Importantly, your book stays live for sale throughout the review process; customers will just see the old cover until the new one is approved.

The Realistic Timetable You Can Expect

Here’s a breakdown of what happens and how long each step typically takes:

Step Expected Duration
KDP review of the new cover file Up to 72 hours (can be longer during busy periods; low-content books may take up to 10 business days)
New cover appears on the store listing Usually happens as soon as the review is complete
Search results update to show the new cover Can take an additional 72 hours
Look Inside / Read Sample updates 7–10 business days (ebooks ~7–8, print ~9–10) — this is consistently the slowest part

The delay in the Look Inside preview is a common source of confusion. Don’t be alarmed if your product page shows the stunning new cover while the preview stubbornly displays the old one. Give it up to 10 business days. If it hasn’t updated by then, reach out to KDP Support with your ASIN.

Crucial Checks Before You Hit Upload

  1. Title and Author Must Match Exactly. Your new cover’s title and author name must be identical to what’s in your KDP metadata. Even a creative redesign that changes the font or styling can be rejected if the text doesn’t match precisely.
  2. Recalculate Your Cover Size if the Interior Changed. Did you also revise the manuscript, changing the page count or paper type? If so, the spine width is now different, and you must rebuild the entire cover wrap. Always verify the new dimensions with the cover size calculator. Using a new design on an old template is a direct path to the cropped-cover problem.
  3. Update Both Paperback and eBook Covers. The paperback wrap and the eBook cover (which must be 1600 × 2560 pixels, per the specifications here) are separate uploads. Swapping one but forgetting the other creates a glaring mismatch on your book’s sales page.
  4. Declare AI-Generated Art if Applicable. The rules about disclosing AI-generated content apply to cover updates as well. Be sure you know what needs to be declared.

Where the Old Cover Might Stick Around

Platforms like Goodreads, BookBub, other retailers, and even some reader apps maintain their own cached cover images. Goodreads, in particular, does not automatically sync with Amazon; updates there are typically handled by volunteer librarians upon request. Expect it to take a week or two for the wider book ecosystem to reflect your change. Avoid the temptation to re-upload repeatedly on KDP—the lag is happening elsewhere.
