How to Create a Coloring Book by Numbers

Coloring book by numbers, also known as paint by number or picture by number is a fun and relaxing hobby for kids and adults alike. Similar to paint-by-number paintings, this niche is relatively rare on Amazon KDP but has the potential for profitability if targeted properly.

To begin, you’ll need to determine the dimensions of your finished coloring book. This is important because your printer will only be able to print within certain size parameters, depending on the type of equipment they use for production. By choosing to design your coloring book to one of the printer’s standard page sizes, you can help keep the costs down as much as possible.

Once the page size has been determined, you’ll need to determine your binding style and page count. Choosing a saddle-stitch binding is usually recommended as it allows the coloring book to lie fairly flat when opened. If your coloring book has a high page count, it may be necessary to choose the Perfect Binding option, which attaches the pages and cover together with a strong glue that will not weaken over time.

To finish the book, it’s also common to include finishing services such as perforating and corner rounding. The perforations are placed near the spine, so that each page can be easily removed from the book and taken to a different work surface for coloring. Corner rounding is a process that gives the edges of the printed pages a soft and rounded appearance.
