How a full wrap cover is laid out
Picture your cover unfolded and lying flat. From left to right it reads: back cover → spine → front cover, with a strip of bleed around the outside edges. KDP prints this single wrap and folds it around the pages.
| Piece | Position | What lives here |
|---|---|---|
| Back cover | Left panel | Blurb, author bio — keep lower-right clear for barcode |
| Spine | Centre strip | Title & author (only if thick enough) |
| Front cover | Right panel | Title, subtitle, author, main art |
| Bleed | Outer edge | Background art that gets trimmed off |
The dimensions, in plain terms
The full template size is driven by three things — trim size, page count and paper:
- Width = trim width + spine width + trim width + bleed on both outer edges (0.125″ each).
- Height = trim height + bleed top + bleed bottom (0.125″ each).
- Spine width grows with page count and depends on paper type.
Let the calculators do the math
Get your full wrap size from the cover size calculator and your spine from the spine width calculator.Designing inside the guides
- Keep titles and text inside the safe zone, away from fold and trim lines.
- Extend background art into the bleed so there are no white edges.
- Leave the lower-right back cover clear for the barcode.
- Only add spine text if the spine is wide enough for your page count.
Use an official template as a guide layer
Download a sized template from the KDP cover template generator and place your art on top of it. Full specs are in the KDP Help Center.Submit as one print-ready PDF
Export the finished wrap as a single 300 DPI PDF at the exact full cover dimensions — not separate front and back images. If something gets flagged, our cover rejection guide walks through the fixes.
