What Are Visuals and Screenshots Best Practices?
Visuals and screenshots should support understanding, not replace it. They show what something looks like, where something lives, or how something changes. They don’t explain why it matters or what to expect.
A good visual reduces friction, while a redundant one adds noise.
What It Looks Like in Practice
Using visuals well usually means you:
- Add a screenshot when layout or location matters
- Highlight the specific area the reader should focus on
- Keep images current with the interface
- Avoid screenshots for information that is clearer in text
For example, in a user guide explaining where to find a rarely used configuration panel, a screenshot with a clear highlight around the exact menu path prevents scanning and guesswork.
The image supports the instruction. It does not replace it.
Why This Matters
Screenshots age quickly. Interfaces change. Labels move.
If your documentation depends entirely on visuals, it becomes brittle.
At the same time, some instructions are unnecessarily difficult without them. Describing a complex navigation path in pure text can create more confusion than clarity.
The goal is balance. Use visuals when they reduce effort. Use text when it explains meaning.
Where Do Visuals and Screenshots Apply?
Visuals are most effective in onboarding material and user guides where spatial orientation matters, such as showing where a button lives, what a dashboard looks like, or how a workflow progresses. When a user is new to an interface, a screenshot can do in seconds what several paragraphs of description cannot.
In API reference documentation, visuals are rarely necessary. Code samples, parameter tables, and structured reference content do the work. Diagrams can be useful for illustrating how systems relate to each other, but screenshots of UI rarely add value here.
Use screenshots with caution in internal knowledge bases and any documentation for fast-changing products. Screenshots are the most maintenance-intensive content type in documentation. An outdated screenshot can mislead more effectively than no screenshot at all. If your product iterates frequently, favor annotated diagrams or described workflows over screenshots where possible.
The question to ask before adding any visual: does this communicate something that text cannot do as well, and will it still be accurate in six months?
Common Misunderstandings
“More screenshots make documentation easier.”
Not always. Too many images slow scanning and make pages harder to maintain.
“A screenshot is enough.”
It isn’t. Images show state. They rarely explain behavior, constraints, or outcomes.
Example
In a troubleshooting knowledge base article:
Instruction:
“Open the Advanced Network Settings panel and turn off the ‘Secondary Routing’ toggle to prevent traffic from being routed through the backup network.”
Without visual support:
The instruction appears alone in text.
With intentional visual support:
Include a screenshot of the panel with the ‘Secondary Routing’ toggle clearly highlighted to confirm location and reduce the chance of toggling the wrong setting.
In the second version, the text still carries the instruction. The screenshot confirms location and reduces the chance of toggling the wrong setting.

Visuals are part of structure. They should be deliberate.
Takeaways
- Add visuals when they reduce friction. Remove them when they don’t.
- Screenshots should support understanding, not compensate for unclear writing.
