1 page = 1 screen works best for me. Yes, changing the font size, etc changes page count, like it would in any physical book. But it is exceedingly rare to mess with those things while in the middle of reading a book. So you still know about how long it will take you to read.

The page count debate is old and settled. Some like the kepub way, some like Adobe page numbers, some like percentage, some like time left. As they said in Diff'rent Strokes "What might be right for you, may not be right for some."

At times, after running those in Sigil, I will then use calibre's editor to merge similar styles—do you really need 6 paragraph styles with the only difference being the line height being set from 1.0 to 1.35?

Out of curiosity, how does that compare to calibre's "Polish book" feature (w/ the related cleanup toggles enabled)?

This is not about the page count for when you are reading, it's about the page count so you have a good idea of how long the eBook may be.

Percent is no good as 100% is useless. Time left is useless as that depends on how long the eBook is and how fast you read. So unless you've read enough of the eBook for the time left to give you a reliable enough number, it's no good. The 1 page = 1 screen also doesn't work because you don't know how many pages there are. And finallt ADE page numbers. They work best because out of the box, they give the most accurate measure.

1 page = 1 screen works very well, it gives me a good idea of how long it will take me to read the current/next chapter, and that's all (i) care about.

It’s uncommon for me to change the font in a significant way in terms of adding or removing pages with 1 screen: 1 page. Thus when I open a book it gives me a good estimate of how long the book is because the text per screen is effectively fixed. Adobe has already been shown to not be fixed as excessive code can cause it to inflate a book by 50-100 pages.

It works for you. Screen to page works for others.

This isn’t a new discussion and the rest of the community has come to accept that we all like different page numbering methods (or don’t care about them at all since pages don’t exist in ebooks).

The same for me. I almost never change the font, its size, line-height or margins. So the text on the screen stays the same size, no matter the book.

100%??? So a book can go from 1000 pages to 0 pages? Or did you mean from 1000 pages to 2000 pages.

And oddly, I tried deleting all the styles from an ebook so only naked tags were left and it changed the compressed size of the epub container by ~7%. This resulted in the synthetic page count dropping by 4%. Repeated strings compress rather well.


Perhaps you were mis-reading jackie_w's post where she mentioned 50-60 pages and in one case 100 pages. On my test book, the page count dropped by 70 pages out of 1750 pages for the original.

Perhaps why saying ADE pages number are consistent for the same edition of an epub on any device is rather common.

When I read an ePub on my Nook (that's where I read ePubs), I tap the screen and a slider comes up telling me how many pages are in a chapter. If it says a chapter is 15 pages, I will have to tap the screen anywhere between 18 and 35 times. When it says there are 2 pages left I may have to read 2, 3 or 4 screens. Possibly five. So yeah, it can vary by 100% (or more).

What you are discussing is the screen page/ratio. What was being discussed was the total number of pages shown by using the Adobe synthetic page algorithm. jackie-w commented how by removing unused and complex CSS which does reduce the size of the text files, the number of pages shown by that algorithm would also reduce. She mentioned losing 50-60 pages and on one occasion, 100 pages. Which a nameless one choose to read as 100%.

As has been made clear in past wars, my opinion is that pages and reflowable text on different screen sizes, font sizes, margins, etc. are at best humourous. The only good thing with the Adobe algorithm is that it is independent of those. Page 348 in an epub will be page 348 no matter what device/screen size/font/font size/etc. the epub is being read on as long as the exact same epub is being read.

We are not talking about while you are reading. This is for the page number stored in Calibre for the entire eBook.

how many pages in this thread though?

[JSWolf]

Whichever page count you prefer is not a problem. It's just that when using the Count Pages plugin, ADE is the only page count that gives you an estimate of how long the book may be.

No it isn’t as has already been discussed to death.
