Trim Size

The Trim Size of the book is pretty much the outside dimensions.

 

Do you know how you want your book to look?

The considerations are;

  • Your preferences – No further comment needed.
  • Industry standards
  • Printer requirements
  • Number of pages

 

Industry Standards/Printer Requiements

 

These are really quite broad, for example should you choose Amazon’s ‘Create Space’ these are the allowable trim sizes;

 

5 x 8       Inches – (12.7 x 20.32 centimeters)
5.06 x 7.81 Inches – (12.9 x 19.8 centimeters)
5.25 x 8    Inches – (13.335 x 20.32 centimeters)
5.5 x 8.5   Inches – (13.97 x 21.59 centimeters)
6 x 9       Inches – (15.24 x 22.86 centimeters)
6.14 x 9.21 Inches – (15.6 x 23.4 centimeters)
6.69 x 9.61 Inches – (17 x 24.4 centimeters)
7 x 10      Inches – (17.78 x 25.4 centimeters)
7.44 x 9.69 Inches – (18.9 x 24.6 centimeters)
7.5 x 9.25  Inches – (19.1 x 23.5 centimeters)
8 x 10      Inches – (20.32 x 25.4 centimeters)
8.25 x 6    Inches – (20.955 x 15.24 centimeters)
8.25 x 8.25 Inches – (20.955 x 20.955 centimeters)
8.5 x 11    Inches – (21.59 x 27.94 centimeters)
8.5 x 8.5   Inches – (21.59 x 21.59 centimeters)

 

Even the most restrictive digital publishers allow;

 

5 x 8   Inches –  (13 x 20 cm)
6 x 9   Inches –  (15 x 23 cm)
7 x 7   Inches –  (18 x 18 cm)
8 x 10  Inches –  (20 x 25 cm)
10 x 8  Inches –  (25 x 20 cm)
13 x 11 Inches –  (33 x 28 cm)
12 x 12 Inches –  (30 x 30 cm)

 

So I guess unless you were being driven by a particular look it could be wiser to choose from the restricted list. Should you do this for a novel, rather than a non fiction or picture book, industry standards produces an even smaller list, namely;

 

5 x 8   Inches –  (13 x 20 cm)
6 x 9   Inches –  (15 x 23 cm)

 

Your choice above will affect the number of pages you book contains. This in turn can affect your commission from a Print on Demand Service. So if commission is a driving factor for you may select the 6 x 9 option.

 

It looked complicated but we now have a choice between two. It’s time to get a tape measure and explore your own library. Which of these two sizes would you prefer?

 

I often think to myself, “Am I wasting my time writing this blog?” and it’s a good question? Years ago in an earlier life I was a Trade Teacher, the wisdom in the college was… if you want to understand a subject – teach it. When I was doing this research I became side-tracked with internal book design, as it too affects the number of pages contained within the book. I was glad I decided to write this section as it has clarified my thinking.

 

For me income is not the deciding factor and I much prefer the less pretentious 8 x 5, so there we go… one decision made.
