Margins are the blank space that surrounds a body of text on every page, and it’s one of the most important elements of interior book design.
Every page includes inner margin (gutter), outer margin, top margin, and bottom margin.
When you open a book, the text looks like it is in the center of the page. This is because the inside margin (gutter) is always bigger than the other margins.
The size of the top and the bottom margins will depend on where you place your page information such as author name, book title, chapter name, and page numbers. Sometimes the page number is in the bottom margin.
Sometimes you need to include a bleed area that extends beyond the page margin or the printing area.
Bleed is an extra 0.125-inch area around all edges of the pages or cover of your book. Bleed is needed on any printed document that has any text or graphic elements that should go off the edge of the page or right up to the edge of the page. Basically, documents that have bleed print on oversized paper, and are later cut down to the right final size. The artwork “bleeds” off the edge of the page, hence the term.
This article helps you choose a trim size and suitable margins for your book.
Since printing costs are based on the number of pages you need to keep control of your printing costs or you will not be able to make a profit from your book. Some authors try to reduce the number of pages by reducing margins and line spacing, which creates a tight layout and makes their book crowded.
This method shows the professional design of the book and creates some aesthetic balance in the text.
Line spacing (or leading) improves the readability of the novel a lot. The choice of line spacing will closely depend on the font choice. Some of them are too tight, and the letters are so close to each other that a reader might even get a headache.
The common practice is to use 1.5 lines, which is also good for screen-reading. But normally line spacing should be between 1.25 and 2.00.
The sink is when you start your text almost in the middle of the page with a lot of white space above it. It is also a clever way to add white space in a book while signaling a change in your storyline. This area of white space is a great opportunity to add a little idea or graphical element. Also, you can use a drop cap.
A drop cap is when you use a large capital letter at the beginning of a text block or paragraph and it has the depth of two or more lines of normal text.
Also, In most professional books it’s not regular to use space before starting each paragraph.
