KDP's print specs call for 0.125" (3.2 mm) of bleed on the top, bottom and outside edges. So an 8.5" × 8.5" book with bleed should be exported at 8.625" × 8.75". The dimension calculator above does this math for any trim size.
Page size versus your trim and bleed setting, art that stops at the trim line instead of extending into the bleed, art touching the edge on no-bleed books, and text or content inside the outside and gutter margins. Always confirm in KDP's official previewer too.
