Frequently asked questions

What size is a 8.5 x 8.5 Lulu paperback cover?

It depends on page count. A 8.5 x 8.5 in Lulu paperback with 200 pages needs a full cover of 17.760 × 8.750 in (5329 × 2625 px at 300 DPI). The height is always 8.750 in.

How much bleed does a Lulu 8.5 x 8.5 cover need?

0.125 in on every outside edge. Keep text at least 0.5 in inside the trim line. Lulu recommends this 0.5 in safety margin on all covers.

Can I put text on the spine?

Lulu allows spine text from 81 pages. Leave some space between the text and each spine edge, because the fold can shift slightly in production.
