O’Reilly Media Illustration Guidelines

This document will help you understand the procedure for using screenshots and technical illustrations in your project.

O’Reilly’s books and products have a uniform, branded appearance that has been well received by our customers for over 30 years. Unless specifically agreed upon, all drawn figures will be created to adhere to O’Reilly Media’s style and branding guidelines.

Examples of our illustrations can be viewed here.

If you have any questions, please contact us.

When creating drawn art and screenshots, please keep in mind the size limitations for a printed book. For instance, 16x9 PowerPoint slides will not scale correctly and will result in illegible text.

The maximum figure size for standard O’Reilly “Animal” titles is:

4.8” x 7” (345.6px x 504px)

Please note that the “Pocket Reference” series is considerably smaller.

2.8” x 5.5” (201.6px x 396px)

Drawn Illustrations

Use whatever method is most comfortable for you when first creating your illustrations: they can be sketched, described in text, or generated using a drawing application.


Screenshots will be processed to ensure correct sizing, and may be slightly darkened/lightened to meet printing specifications.

If you need to add callouts (such as arrows, boxes, or explanatory text) to your images, please include two versions of the image: a “clean” version without callouts, and a version that indicates the callouts you want. Our Illustrator will use standard O’Reilly fonts and specs to add callouts to the clean file, using your example as a guide.

Naming Your Files/Organizing with a Figure List

A well-organized figure list allows us to move your book through production more quickly and accurately. The figure list should contain the filename, position of the figure in the book, and other information, such as; required callouts, or notes.
