Start with one number or fact, not a whole story

An infographic works best when it shows one thing clearly — a single comparison, a process with three steps, or how one number breaks down. The moment you try to pack five separate ideas into one image, it stops being an infographic and becomes a poster that nobody reads.

Before you open any design tool, write down the one fact or relationship you want to show. "Renewable energy sources in the US" is too broad. "Solar power grew from 2% to 4% of US electricity between 2020 and 2023" is the kind of specific claim that becomes a real infographic. The constraint is what makes it work.

Key Takeaways

  • Choose a chart type that matches your data: bars for comparing amounts, lines for change over time, pie charts only when you have three to five categories that add to 100%.
  • Use no more than three colors, and pick colors that stay distinct when printed in black and white or viewed by someone with color blindness.
  • Label every number, axis, and unit directly on the image so the infographic stands alone without a caption.
  • Canva, Piktochart, and Infogram all let you start from templates and swap in your own data without learning design software.

Pick the right chart shape for what you are showing

The chart type is not a decoration — it is the argument. A bar chart says "these things are different sizes." A line chart says "this changed over time." A pie chart says "these pieces make up a whole." If you pick the wrong one, your reader has to work backward to understand what you meant.

Use a bar chart when you are comparing amounts across categories: "Which streaming service has the most subscribers?" or "How much does rent cost in each neighborhood?" Bars make the size difference obvious at a glance. Use a line chart when something changes over time: "How did unemployment move from 2020 to 2024?" or "When do people use public transit most?" Lines show the direction and speed of change. Use a pie chart only when you have three to five categories that add up to 100% — "Where does the city budget go?" or "What percentage of households have internet?" More than five slices and the chart becomes unreadable.

Avoid doughnut charts, 3D effects, and stacked bars unless you have a specific reason. They look fancier but make the numbers harder to read. Your job is clarity, not decoration.

Label everything so the image works alone

An infographic should make sense without a caption, a headline, or you standing next to it explaining. Every axis needs a label. Every number needs a unit. The title should say what the data shows, not just "2024 Statistics."

Put the label directly on or next to the data, not in a legend off to the side. Instead of a color key that says "Red = North, Blue = South," write "North" and "South" right on the bars or regions. If your chart shows percentages, write the % symbol. If it shows dollars, write $ or "millions of dollars" so the reader knows the scale. A reader should be able to screenshot your infographic, post it anywhere, and someone who has never seen your original article should still understand it.

Use color to separate categories, not to decorate

Color should do work. Use different colors to show different categories — one color for each bar, or one for each line. Use the same color for the same thing every time so the reader's brain can track it. Do not use color just to make the image prettier.

Pick colors that stay distinct when printed in black and white and that work for people with color blindness. Red and green together are hard for many people to tell apart. Blue and orange work better. If you are not sure, test your image by converting it to grayscale in your design tool — if the bars or lines still look different from each other, your colors work. Limit yourself to three colors maximum. More than that and the image gets chaotic.

Use templates to avoid starting from blank

Canva has hundreds of infographic templates organized by type: "Timeline," "Comparison," "Process," "Statistics." You pick a template, delete the sample data, paste in your own numbers, and the layout, fonts, and colors are already done. It is the fastest way to make something that looks professional without learning design software. Canva is free for basic use, with paid templates available.

Piktochart and Infogram work the same way but focus specifically on infographics and data visualization. Infogram is stronger if you have a spreadsheet of data you want to upload all at once. Piktochart is simpler if you are building something small. Both have free tiers with limited templates and paid plans that unlock more.

All three let you change colors, fonts, and layout after you pick a template. The template is a starting point, not a cage. Start there, swap in your data, and adjust until it looks right.

Make sure your numbers are correct before you design

An infographic with wrong data spreads faster than one with right data because it is more memorable. Before you open a design tool, write down every number you plan to use and check it against your source. If you are pulling from a government website, a research paper, or a news article, write down where it came from so you can verify it later if someone asks.

If your data comes from different years or different sources, say so. "2023 data from the Census Bureau" is better than just a number with no context. If you are combining data from multiple places, make sure they are measuring the same thing the same way — unemployment rates from different countries might use different definitions, for example.

Keep text short and let the chart do the work

Every word you add to an infographic is a word the reader has to read instead of looking at the data. Write a title that says what the chart shows. Add a subtitle if you need to explain the time period or source. Then stop. Do not write a paragraph of explanation. If you need paragraphs, you are making an article with a chart in it, not an infographic.

The same rule applies to labels. "Q1" is better than "First Quarter of the Fiscal Year." "Millions of dollars" is better than "The amount of money in millions of US dollars." Short labels let the reader focus on the pattern in the data, not on decoding the words.

Frequently Asked Questions

What size should I make my infographic?

Make it taller than it is wide — roughly 1200 pixels wide by 1600 pixels tall works for most social media and websites. If you are printing it, ask your printer what size they need. Canva, Piktochart, and Infogram all let you change the dimensions before you start, so pick the right size first.

Can I use data from a news article or research paper?

Yes, but cite where it came from. Write the source and year directly on the infographic or in a caption below it. If the original source is behind a paywall or hard to find, link to it in the text around the image so readers can check your work.

What if my data has too many categories to fit in one chart?

Make two infographics instead of one. "Top 5 Reasons" is clearer than "All 12 Reasons Crammed Into One Image." If you have a lot of data, break it into separate infographics, each showing one relationship or comparison.

Do I need to hire a designer?

No. Templates in Canva, Piktochart, and Infogram are designed by professionals and work for most situations. You only need a designer if you have a very specific look you want or if you are making dozens of infographics and want them all to match a custom style.

What if I want to show change over time with multiple categories?

A line chart with multiple lines works if you have three or fewer categories. If you have more, a stacked bar chart (bars divided into colored sections) can work, but it is harder to read. Consider making two separate infographics instead — one for each category over time.
