How big should your book be?

I started writing a book about Donald Trump in early January. I initially thought it would be a short book, with about 150 pages. I figured that the paperback would sell for $9.95 and the ebook for $4.99.

My tentative "pub date" was March 1 (eight days ago). I am now figuring on publishing around April 10. It's not unusual for books to be published later than originally planned. The book has grown, too. It looks like the paperback will have about 220 pages, and will probably sell for $15.95. I think I'll raise the ebook price to $5.99.

Every day I find more material that can go into the book, but at some point I have to stop writing. The book must end, and can't be ridiculously large.

The bigger the book, the longer it takes to finish writing, editing and formatting it, the more it costs to produce and purchase, the more errors it will have, and maybe the fewer people who will buy it.

I almost never go to movies that are longer than two hours, because I know the movie will become a $12 nap. I am similarly reluctant to buy books with more than about 350 pages, because I doubt they will keep me interested.

In an online forum for authors, a newbie discussed his debut novel -- which was planned to have more than 800 pages.

• It will be extremely difficult to persuade people to buy a huge and expensive book written by someone they've never heard of.

Maybe that book should become three books, or should be drastically cut.

• Almost any page can sacrifice a sentence or two without suffering. 
• Most sentences can shed a word or two, and no reader will miss them.

The maxi­­mum number of pages for a book is determined by print­ing and binding equip­ment (if the book is printed) and what people are willing to pay, carry and read.

One the other hand, the United Nations’  Educational, Scientific and Cultural Organ­iz­a­tion declared 49 pages to be the min­imum length for a book. A publication with fewer pages can be a leaflet, pamphlet, booklet or brochure. Call it a book, and you risk offending nearly 200 nations.

Despite the UNESCO decree, no printed book has 49 pages. Pbooks have an even number of pages even if some pages don’t have numbers on them. An individual piece of paper in a book is called a leaf. Each leaf has two sides, called pages. A 100-page book contains 50 leaves. Or leafs.

Publishers don’t have to obey the United Nations. Outskirts Press can make “books” with as few as 18 pages, the minimum from Create­Space is 24 pages, and Lulu can do 32 pages.

Most printers can produce books with as many as 800 to 1,000 pages, but books with more than 500 pages are unusual. With nonfiction, you need to have enough pages to cover your topic adequately. Don’t skimp, or pad.

• The book should not be so big that it will be priced a lot higher than its competitors or seem like “too much to read.”
• It should not be so short that it seems incomplete, or doesn’t offer value for its cost.

The form of a book affects the acceptability of its size. A printed book with 600 pages could be heavy to carry and difficult to lay flat (and expensive to print and ship). 

The cost of each additional page printed is insignificant. The cost of each e-page is zero. There is a prejudice against very thin books, so try for a minimum of about 120 pages. Thin books just don’t seem like real books, and the printing on the book’s spine will be tiny.

Novels can be much longer than nonfiction. Tolstoy’s War and Peace is about 1,300 pages long, and some of Rowling’s Harry Potter books have over 700 pages.

A book’s page count is not final until it is ready to be printed. Many factors determine how many words fit on a page, including page size, type size, line spacing, margins, headers, number and size of illustrations, front and back matter, etc.

An 8.5-by-11-inch manuscript page holds about twice as many words as a common 6-by-9-inch book page. A 200-page manuscript can yield a 400-page book (with no graphics), and have about 100,000 words.

Most ebooks don’t have real pages. I know of one ebook with just nine “pages” and one with 1,594 -- unless the person reading makes an adjustment which changes the total.

With most ebooks, the readers can adjust typeface, type size and vertical/horizontal orientation. That changes the number of apparent pages. A hundred people could read a particular ebook, but they’re not necessarily reading the same book. 

Publishers Weekly analyzed data from Amazon.com and declared that the median average "word count" for books is 64,531 words, which translates to about 290 paper pages. While a mean average might be more useful than the median (half of the books have more words, half have fewer), the number from PW is still useful. It’s probably best for new writers not to stray too far from the average.

It’s normal for writers to love their words -- but readers may not share the love. Some writers who love their words recognize that there are just too many words. I voluntarily cut a book I wrote from 518 pages to 432 pages, and it’s better because of the cuts. It may have been even better at 396.
