Book Cover Gen

What is Book Cover Gen?

BookCoverGen helps indie authors size a KDP paperback wrap before upload. Enter trim size and page count; the free calculator returns spine width, bleed, and safe-area measurements you can use on a wrap. Authors can also generate a free watermarked AI cover preview with no account. If you already have a near-finished cover and want a designer to polish the front file, that work starts at $19 and is quoted before it begins—this is cover polish of an existing file, not a full custom commission. No subscription is required for the free calculator or the watermarked preview.
