Why your booklet PDF looks out of order (and why that is correct)
You made a booklet PDF, opened it, and the pages are all over the place: the last page sits next to the first, page 2 next to the second-to-last. It looks broken. It is not. A booklet PDF is laid out for the paper, not for the screen, and once it is printed, folded and nested, every page lands exactly where it belongs.
Short answer: do not fix the order. Print it two-sided, flipped on the short edge, fold the stack in half, and read it. That is the test that counts.
What a booklet PDF actually contains
A booklet is a stack of sheets folded in half. Each sheet carries four pages, two on the front and two on the back, and the outermost sheet holds both the first and the last page. So the PDF is not a list of pages, it is a list of sheet sides, each with two pages next to each other.
An 8-page booklet needs two sheets:
| Front: left | right | Back: left | right | |
|---|---|---|
| Sheet 1 (outside) | 8 | 1 | 2 | 7 |
| Sheet 2 (inside) | 6 | 3 | 4 | 5 |
On screen that reads 8, 1, 2, 7, 6, 3, 4, 5. Fold sheet 2, put it inside sheet 1, fold both, and you turn the pages 1, 2, 3, 4, 5, 6, 7, 8.
The pattern is always the same: on every sheet side, the two page numbers add up to the page count plus one (8 + 1 = 9, 2 + 7 = 9, 6 + 3 = 9, 4 + 5 = 9). If your PDF follows that rule, its order is right.
Check it in one minute, before printing a stack
- Print one copy, two-sided, flipped on the short edge.
- Put the sheets on top of each other in the order they came out of the printer, and fold the whole stack in half.
- Flip through it. If the pages read 1, 2, 3, … the PDF and your printer settings are right, and you can print the rest.
A quick trick if your document has no page numbers: write the numbers on a test copy by hand, then fold.
Three things that really do scramble a booklet
The PDF is rarely the problem. These are:
1. Flipping on the long edge
Booklet sheets are landscape and folded across the middle, so the back has to flip on the short edge. Flip on the long edge and every back side comes out upside down: page 2 and page 7 are standing on their heads. Change one setting in the print dialog and print again.
2. Printing a booklet PDF with the printer's own "booklet" option
Many printer drivers and copiers have a "booklet" or "saddle stitch" layout. It reorders the pages itself. Use it on a PDF that is already a booklet and the pages get reordered twice, which really does scramble them. Use one or the other: either an ordinary PDF with the printer's booklet option, or a booklet PDF printed normally. (Booklet finishing that only folds and staples is fine.)
3. "Fixing" the order on screen
Dragging the pages back into 1, 2, 3 order in a PDF editor before printing undoes the imposition. The printed booklet is then out of order for real.
Why there are blank pages
Every sheet carries four pages, so a booklet always has a multiple of four. A 10-page document becomes 12 pages with two blanks at the end. If your last page is a back cover, put it on the outside instead: BookletPro's Use last page as back cover keeps it there and places the blanks inside.
Let the app do the order
BookletPro makes the booklet PDF from your normal document, shows a note next to the preview that the shuffled order is correct, and from version 3.3 sets up two-sided, short-edge printing for you. Booklets of up to 32 pages are free on iPhone, iPad, Mac, Android and in the browser. Your PDF never leaves your device.
