A 50,000-word manuscript is approximately 182 pages in a standard 6" x 9" book with 11pt font and 1.15 line spacing (~275 words per page). In a smaller 5" x 8" format, it would be around 222 pages. Page count varies significantly based on trim size, font size, line spacing, and margins.
A typical book page contains 250-300 words in a 6" x 9" format with standard formatting. Smaller trim sizes like 5" x 8" fit about 200-225 words per page, while larger formats like 8.5" x 11" can hold 400+ words per page. Font size, line spacing, and margins all affect words per page.
Most novels fall between 40,000 and 100,000 words. Genre conventions vary: Romance novels typically run 70,000-100,000 words, Thrillers 70,000-90,000, Fantasy 90,000-120,000, and Young Adult 50,000-80,000. First-time authors are generally advised to stay between 70,000-90,000 words.
An 80,000-word book is approximately 291 pages in a 6" x 9" format with standard 11pt font and 1.15 spacing. This is a typical length for a novel. In a 5.5" x 8.5" format, it would be around 334 pages.

Spine width depends on page count and paper type. For KDP white paper, multiply your page count by 0.002252 inches. For example, a 300-page book has a spine width of 0.676 inches (about 17.2mm). Our calculator computes this automatically for each trim size.
Yes, font choice significantly affects page count. Garamond tends to be more compact, fitting about 5% more words per page than Times New Roman. Georgia is slightly larger, fitting about 5% fewer words per page. Choosing the right font can add or remove 10-20 pages from your book.
A 100,000-word manuscript is approximately 364 pages in a standard 6" x 9" book with 11pt font and 1.15 spacing. In a 5" x 8" format, it would be about 445 pages. This is a common length for Fantasy, Science Fiction, and Literary Fiction novels.
The most popular trim size for novels is 6" x 9" or 5.5" x 8.5". For non-fiction and self-help, 6" x 9" is standard. Children's books often use 8.5" x 11". Choose a trim size that matches reader expectations for your genre and keeps page count reasonable (not too thin or too thick).
Line spacing has a major impact on page count. Switching from 1.15 spacing to double spacing can increase your page count by roughly 60%. Single spacing reduces it by about 20%. Most traditionally published books use 1.15 to 1.5 spacing for comfortable readability.
