Mockups: showing a book that does not exist yet
A flat cover is a rectangle. It is obviously an image — a JPEG someone made on a computer, sitting on a screen among other JPEGs.
A mockup is the same artwork rendered as a physical thing: a paperback standing on a table, a stack of three with the top one face up. Nothing about the book has changed. What has changed is that the reader is looking at an object, and people respond to objects in a way they do not respond to files. An object has weight, a thickness you can estimate, a place it could sit on a shelf.
That is the whole trick. A mockup does not make your cover better. It makes your book real.
Where a mockup earns its place
Ads. A paid social ad competes with photographs of actual things. A flat cover reads as a graphic and gets scrolled past; a rendered book reads as a product.
Social posts. Announcements, cover reveals, progress updates, launch day. This is where mockups do the most work, because the feed is full of photographs and a flat file looks like an ad for something unfinished.
Your newsletter. A rendered copy at the top of a launch email says this exists now faster than a sentence can.
Your author site. A book page with a physical copy on it looks like a catalog entry. A book page with a flat cover on it looks like a folder.
A pre-order page. The reader is being asked to commit to something that has not shipped. Showing the object is exactly the reassurance the moment needs.
A press kit. Reviewers, bloggers and local press want an image they can drop into a post. Give them both and let them choose.
Where it does not belong
Never as the main product image on a store listing. Amazon, Ingram and every other retailer want the flat cover, front only, edge to edge, no shadow, no perspective, no table. That image is a specification, not a marketing asset, and a mockup in that slot will look wrong next to every other book in the results — or get rejected outright.
Keep the two jobs separate. Flat cover for the store. Mockup for everywhere you are doing the persuading yourself.

What makes a mockup look fake
Readers cannot usually name the problem. They just feel that something is off, and the shot stops doing its job.
The light has to agree with itself. Perspective and shadow are one system. If the book is turned to the left and the shadow falls to the left as well, the scene is lit from two places at once. Same for a crisp hard shadow under a book in soft, diffuse light. Nobody consciously checks this; everybody notices it.
The spine has to be the real spine. A 400-page novel with a spine that looks like a pamphlet, or a 90-page poetry collection with the spine of a doorstop, reads as wrong even to someone who could not tell you why — because everyone has held books and knows what page count feels like. Spine width comes from the page count and the paper, and a mockup that guesses gets it visibly wrong.
A hardcover is a different object from a paperback. Boards overhang the pages, the cover does not bend, and the corners are square. Showing a hardcover for a book you are printing as a paperback does not look aspirational; it looks like a stock image, which is exactly the impression you were trying to avoid.
Use the finished cover. Not the draft with the placeholder subtitle, not the version before you fixed the title size. A mockup circulates. Early drafts have a way of outliving the moment you shared them.
The honesty line
A mockup is a picture of a book you are going to sell. It should not be a picture of a book you are not.
If your book is ebook-only, a photorealistic paperback on a wooden table is a promise you have no way of keeping. Readers will click through expecting to buy the object you showed them, and finding out there is no such object is a small, specific disappointment that costs you more than the pretty image gained. Show a device mockup instead, or the flat cover. If print is coming later, say so in the post.
The same goes for a hardcover you have not set up and a box of author copies you never ordered. Show what exists, or what you have definitely committed to making.
Motion does more than a still
A short video of the book turning — front, spine, back, front again — outperforms a still on nearly every social platform, because motion is what the feed is built to reward. It also answers a question a still cannot: how thick is it, and what is on the back.
Ten to fifteen seconds is plenty. Vertical, because that is how the feed is held.
In the tools. The Social Pack makes a 15-second vertical video and matching stills from the same cover, so the clip and the images you post around it are the same book. Start a book → · about the tools
