Best Practices for Word Clouds

What makes a well-designed word cloud? First, let’s be clear: some word clouds are functional, while others are decorative.

A functional word cloud — for work, analysis, or presentations — needs to be readable. That means:

  • Appropriate word sizes for clarity.
  • Good color contrast to ensure words stand out.
  • A well-balanced number of words—too many can clutter the design.

A decorative word cloud — for gifts, social media, or creative projects — can break the rules and still look amazing. Just like in fashion, style matters most. Consider:

  • A birthday word cloud could include 🎈 emojis as words. Sure, they’re small and unnecessary — but a word cloud full of balloons?! Perfect!
  • A New Year’s word cloud might blend into the background in places, but the overall design still captures the spirit of the celebration.

The right combination of words, colors, fonts, and layout makes all the difference. Here’s what to focus on when designing a word cloud.

1. Choosing the Right Words

It’s right in the name: words are the foundation of any word cloud. A strong word cloud:

  • Focuses on key terms rather than generic filler words.
  • Uses relevant words for the intended audience — professional terms for a résumé, emotional words for a gift.
  • Can use a pinned word in a contrasting color and large font to highlight an idea or proclaim the topic.

For a stellar image, apply these bonus tips:

  • Stick to one part of speech — for example, all nouns or all verbs.
  • Balance long and short words, especially when filling a shape. Short words help define the edges and prevent empty spaces.
  • Add small decorative elements. For example, Christmas word clouds often look better with a couple of ❄️ snowflake emojis.
  • On the other hand, if your word cloud is more professional than decorative – like in a business or academic word cloud – skip the decorative elements and filler words to keep it clean and readable.

2. Colors: Balancing Readability and Aesthetic

Words matter, but the color palette sets the tone. A word cloud with amazing words can be ruined by poor color choices. A good word cloud:

  • Uses high contrast between text and background.
  • Sticks to a limited palette for clarity.
  • Matches the theme — e.g., bright and playful for a birthday card, muted and professional for a business report.

Bonus tips to take it to the next level:

  • Use the color picker to match your brand colors or wedding color scheme.
  • Try gradient colors — but don’t overdo it. Gradient words can be hard to read on a gradient background.
  • Consider removing the shape background, border, or both. Let the words themselves form the shape.
  • A transparent background is great for printing.

3. Image Background: To Use or Not to Use?

Background images can enhance a word cloud but should never overwhelm the words. If using a background image:

  • Keep it subtle or use a semi-transparent overlay to maintain readability.
  • Ensure words remain the primary focus by adjusting contrast.

Bonus tips:

  • Use the color picker to match text colors to the background for a cohesive look. Slightly adjust brightness for better contrast.
  • Set the background image to a lower opacity to make words more prominent. This allows the background color to begin showing through. A dark background works well with light text, and vice versa.

4. Shape: Meaning Beyond Words

Shapes influence how a word cloud is perceived. Consider:

  • No shape is often a good choice.
  • Simple shapes (circles, rectangles) suit professional or analytical use.
  • Thematic shapes (hearts, animals, holiday symbols) add personality to creative projects.
  • Custom logos or silhouettes work well for branding and marketing.

Bonus tips:

  • A simple letter or number shape can make a strong statement — like “5” for a 5th birthday or “V” for a Valentine’s Day card.
  • Check out the themed shape packs in the editor for unique designs.

5. Picking Good Fonts

Font choice affects readability and tone. Here are some tips:

  • Match the font to the topic.
    • For professional word clouds, use clean, bold fonts like Bevan or Arial Black.
    • For a fun or decorative look, try handwritten or curly fonts.
  • Mixing fonts can create interesting contrast — e.g., bold DayPoster Black with handwritten Yesteryear.
  • Check readability at small sizes, especially for printing.

Extra tips:

  • Stuck? Try the “Random fonts” button.
  • Some fonts don’t support all languages—if your text isn’t displaying correctly, switch fonts.

6. Font Sizes

Font size distribution should reflect word importance without making small words unreadable. Consider:

  • A mix of large and small words for a dynamic layout.
  • Check the minimum font size.
    • If set too high (e.g., 70), many words won’t fit. If words disappear, adjust font size.
    • If set too small, some words won’t be readable.

7. Image Size and Resolution

For printing, presentations, or social media, resolution matters:

  • Default image size – 1200x1200px – works well for most uses.
  • High-resolution images (higher DPI) are better for printing.
  • Aspect ratios matter for social media:
    • Square for Instagram.
    • Landscape for Twitter and presentations.
    • Portrait for Pinterest and mobile wallpapers.
