Infographic Design: How to Build One That Actually Explains Something

Most things called infographics are lists with icons. A heading, six bullet points, a small illustration beside each, a logo at the bottom. It is a document that has been decorated rather than a graphic that explains something.

Real infographic design starts from a different question: what relationship in this information is hard to see in words and easy to see in a picture? If there is no such relationship, the answer is a well-formatted list, and that is a perfectly good answer.

This guide covers when an infographic is genuinely the right format, how to structure one, how to choose chart types honestly, and the mistakes that make them unreadable.

When an Infographic Is the Right Format

Visual form earns its place when the information has a shape:

• Comparison — several things measured against the same criteria.
• Process or sequence — steps in a defined order, particularly with branches or loops.
• Proportion — how a whole divides.
• Change over time — a trend that a table obscures.
• Relationship or hierarchy — how parts connect or nest.
• Geographic distribution — anything where location is the point.
• Scale — quantities too large or small to grasp without a reference.

It is the wrong format when the content is a set of unrelated points, when the argument depends on nuance and qualification, when the data is too thin to be interesting, or when the real motivation is that a post needs an image. Decorating six bullet points does not make them more memorable; it just makes them harder to read on a phone.

Start With One Message

Ask what someone should be able to say after looking at it for ten seconds. If you cannot state that in a sentence, the infographic is not ready to design.

That single message then governs every decision — what to include, what to cut, what gets the most visual weight. Infographics that try to convey five things convey none, because the eye has nowhere to land first.

A workable process:

1. Write the one-sentence message.
2. List everything supporting it, then cut anything that does not.
3. Identify the shape — comparison, process, proportion, change over time.
4. Sketch the structure roughly, on paper. This takes five minutes and prevents hours of rework.
5. Decide the reading path — where the eye starts and where it goes.
6. Design it, then remove whatever is not doing work.

Building the Thing

Structure and reading path

An infographic needs a deliberate order, because unlike a paragraph, the eye can enter anywhere.

• A clear entry point. Usually a title stating the message rather than the topic. "Support tickets fell 40% after the form redesign" works harder than "Support ticket analysis".
• An obvious next step. Size, colour and position tell people what to look at second.
• Grouping that reflects meaning. Things near each other are read as related, so proximity must match the logic.
• Consistent direction. Pick top-to-bottom or left-to-right and hold it. Direction that changes halfway loses people.
• A conclusion. Something at the end — a summary, a takeaway, a next step.

On format: tall vertical infographics suit web and social, where scrolling is natural. Landscape suits presentations and print. Designing one and cropping it to the other rarely works, because the reading path changes.

Choosing charts honestly

Most infographic failures are chart failures. A few durable guidelines:

Beyond chart choice, three honesty rules that matter:

• Start bar chart axes at zero. Truncating the axis exaggerates differences and is the most common way charts mislead — usually unintentionally.
• Scale areas by area, not by width. Doubling the width of a circle or icon quadruples its area, so a 2× value looks like 4×.
• Avoid 3D effects. They distort proportions and add nothing.

Also: cite the source, and give the sample size and date where relevant. An infographic with unattributed numbers is decoration. One with a clear source is something people will reference and link to, which is generally the point of making it.

Type and colour

Typography carries most of the hierarchy:

• Two typefaces at most, and one is often better.
• Three or four sizes with clear differences between them. Sizes that are nearly the same read as a mistake.
• Labels large enough to survive the sizes people actually view at.
• Horizontal text wherever possible — rotated labels are hard to read and usually signal a chart type that is not working.

Colour should carry meaning rather than decorate:

• Use a limited palette, with one accent for what matters most.
• Keep the same colour meaning the same thing throughout.
• Check contrast, and never rely on colour alone to distinguish categories — pattern, position or direct labelling should also work.
• Consider colour vision deficiency; red and green as the only distinction is a common and avoidable problem.
• Remember it may be printed in greyscale, where similar tones merge.

Illustration and icons

Icons and illustration are where infographics most often drift into decoration. A few working rules:

• Use one icon set in one style. Mixing outline icons with filled ones, or flat with three-dimensional, reads as assembled rather than designed.
• Icons should label, not fill space. An icon beside a statistic helps someone scan; an icon beside every line of text becomes visual noise the eye has to work past.
• Avoid the generic set — the lightbulb for ideas, the handshake for partnership, the target for goals. They carry no information and date quickly.
• Check licensing on any icon or illustration set before publishing, particularly for commercial use.

The general principle: if removing an element would not change what the reader understands, it is decoration. Some decoration is fine; decoration that competes with the data is not.

Sourcing and checking the numbers

An infographic gives numbers an authority that a sentence does not, which makes accuracy more important rather than less.

• Go to the original source, not to another article citing it. Figures degrade as they are repeated, and rounding errors compound.
• Record the date and the sample. A statistic without a date is unusable within a couple of years.
• Check the figure means what you think. "Growth of 40%" can be year on year, since launch, or against forecast, and those are different claims.
• Do not mix sources in one chart unless methodologies are comparable.
• Cite visibly on the graphic itself, since infographics get shared away from the page they were published on.

Where It Will Be Seen

A common failure is designing at full size on a large monitor and publishing to an audience on phones.

• Social feeds show a small preview, so either design for that size or split long infographics into a carousel.
• Web pages scale images down, so 9pt labels become illegible. Consider offering a full-size or downloadable version.
• Presentations are viewed from a distance, which means fewer elements and much larger type.
• Print needs 300 dpi and CMYK — the requirements are set out in preparing a print-ready PDF.
• Email often blocks images, so essential information should not live only inside the graphic.

On accessibility: an infographic is an image, so its content is invisible to screen readers. Provide a text alternative — a summary in the surrounding content, a data table, or meaningful alternative text. The approach is covered more fully in making documents accessible.

Common Mistakes

• A list with icons, not an infographic.
• Too much content, with no single message.
• Decorative charts that misrepresent the data.
• Truncated axes exaggerating differences.
• Icons scaled by width rather than area.
• No source for the numbers.
• Text too small at real viewing size.
• Colour carrying meaning with no secondary cue.
• No clear reading path, so the eye wanders.
• No text alternative, making the content inaccessible and invisible to search.

Conclusion

An infographic is worth making when information has a shape that words hide — comparison, sequence, proportion, change. It works when it carries one message, has a deliberate reading path, uses chart types honestly, and remains legible at the size people will actually see it.

If you cannot name the single thing someone should take away in ten seconds, the honest answer is usually that the content wants to be a short article with one good chart in it.

Getting Infographics Designed

SBTEXMEDIA designs infographics and data visuals for businesses, consultants, agencies, publishers, schools and non-profits — structure and reading path planned before design, chart types chosen to represent the data accurately, typography and colour used to carry hierarchy rather than decorate, versions prepared for the formats you publish in, and text alternatives provided so the content remains accessible and searchable. Existing infographics can be reviewed and rebuilt where the data is being misrepresented.

Related work on graphic design for small business, presentation design and social media templates is handled by the same team.
