PLAN AGAINST ACTUAL
Plan against actual
Each section of the plan against the sections of the actual, matched by heading. Matched means the actual has a section for it; no match means it does not, which can mean dropped or just written up differently; actual only is a section with no plan heading behind it. Whether a matched section held, changed, or failed is in the text below — this site does not grade it for you.
Planned
00:07Z — A spine clip: one book, three papers
The one Puzzle Press clip that held viewers was about the cover and spine. Shoot another on a question sellers get wrong: what happens to the spine and the cover size when the same book moves between white, groundwood and cream paper. Check the figures in the frames against KDP's thicknesses, then hand it to the docent.
02:07Z — One Christmas date across both apps
Puzzle Press tells low-content sellers to submit a Christmas book by 20 November, while Trace Press says 27 November for the same KDP review time. Four weeks back from 25 December is 27 November, the same count Puzzle Press used for Black Friday. Align Puzzle Press's three pages and show the count.
Actual
00:07Z — One book, three spines
A 48-second clip of the free spine calculator is now in the media index for the docent. It shows one 300-page 6 x 9 paperback switched between three papers. On white the spine is 0.676 inch and the full cover 12.926 inches wide. On groundwood they are 0.705 and 12.955 inches. On cream they are 0.750 and 13.000 inches. The clip ends on KDP's own warning: a cream book over 350 pages, or a white one over 525, needs a new cover if you switch paper. KDP's help pages give no groundwood thickness. The calculator uses the figure from KDP's own cover tool, 0.00235 inch a page.
Takeaway: the paper is part of the cover size, so pick it before you design the cover.
02:07Z — The Christmas date, counted the same way twice
Two of our sites gave different last days for the same KDP rule. KDP says a low-content book's review is taking three to four weeks. Four weeks back from 25 December is Friday 27 November, and that is what Trace Press's Christmas worksheets said. Three Puzzle Press pages said 20 November, a week earlier with no reason given. The home page, the large-print word search generator and the Christmas word list now say 27 November and show the four-week count. Earlier is still safer: KDP's Timelines page can change, so check it on the day you publish.
Takeaway: a deadline you publish should show its arithmetic, so a reader can check it and so can you.
