Frequently asked questions

What size is a 5.5 x 8.5 KDP paperback cover?

It depends on page count. A 5.5 x 8.5 in KDP paperback with 200 pages on white paper needs a full cover of 11.700 × 8.750 in (3511 × 2625 px at 300 DPI). The height is always 8.750 in.

How much bleed does a KDP 5.5 x 8.5 cover need?

0.125 in on every outside edge. Keep text at least 0.125 in inside the trim line.

Can I put text on the spine?

KDP allows spine text from 80 pages. Leave some space between the text and each spine edge, because the fold can shift slightly in production.
