Using illustrations in work manuals and step-by-step guides

Published: 10月 6, 2026

In a work manual or step-by-step guide, illustrations are not decoration. They show what to do at a glance and reduce mistakes. Here is how to use them well when writing manuals.

One step, one illustration

The basic rule for procedures is one illustration per step. With a picture beside each numbered step, readers can follow the flow without reading every word. Try to show several steps in one picture and it becomes unclear which action belongs to which step.

Stamping a document illustration (Line style) — Stamp the document → put it in an envelope → sort into trays: one illustration per step

Actions versus tools

Illustrations fall into two broad groups: actions, showing a person doing something, and tools, showing objects on their own.

Action illustrations show what to do — for example, stamping a document or weighing a package
Tool illustrations show what to use or prepare — for example, a checklist of supplies or where equipment is kept

Use tools for “what you need” lists and actions for the steps, and the structure of the manual becomes easy to follow.

Say the same thing in words and pictures

An illustration supports the text; it does not replace it. When “Stamp the bottom right of the form” sits next to a picture of someone stamping a form, readers can confirm the same point twice. Putting important information only in the picture — or only in the text — invites mistakes.

Make cautions stand out with color and placement

For steps where errors are risky, set them apart: change the illustration’s line color to your warning color (a red tone, for example) or place it inside a caution box. Highlight only what truly matters — if every step is emphasized, nothing is.

Inspecting a fire extinguisher illustration (Line style) — For safety and equipment checks, use illustrations that show the task being done

Reuse the same illustration for the same action

If the same action appears several times in a manual, use the same illustration every time. Readers learn that “this picture means this task,” so later steps are understood at a glance. A similar but different picture makes them wonder whether it is a different task.
