When it comes to B2B design, simplicity is your best friend. Overcomplicating layouts, colors, or messaging can confuse your audience and dilute your brand. That’s where the rule of 3 comes in. It’s a simple, memorable framework that helps you create clean, professional designs without needing a design degree.

In this post, we’ll break down how the rule of 3 applies to fonts, colors, layout, and more. By the end, you’ll have a toolkit of easy-to-apply tips to instantly improve your B2B design.

‍

1. 3 fonts max: keep it clean and consistent

Fonts are one of the easiest ways to make or break your design. Too many fonts can make your content look chaotic, while too few can feel flat. The sweet spot? Three fonts max. Here’s how to use them effectively:

• Headline font: Choose something bold and attention-grabbing for titles and headers.
• Body font: Pick a clean, easy-to-read font for paragraphs and longer text.
• Accent font: Use a decorative or stylized font sparingly for emphasis (e.g., quotes or callouts).

Pro tip: Stick to fonts that align with your brand personality. For example, sans-serif fonts like Helvetica feel modern and clean, while serif fonts like Times New Roman feel more traditional and formal.

2. 3 colors max: balance and brand consistency

Color is a powerful tool in design, but it’s easy to overdo it. Using too many colors can overwhelm your audience and dilute your brand identity. Instead, stick to three colors max:

• Primary color: Your main brand color, used for headlines, buttons, or key elements.
• Secondary color: A complementary color for accents or highlights.
• Neutral color: A background or balancing color like white, black, or gray.

This approach keeps your designs cohesive and professional while ensuring your brand colors shine.

3. Divide your space into thirds: embrace white space

White space (or negative space) is one of the most underrated design tools. It gives your content room to breathe and makes your designs look polished. A good rule of thumb? Keep one-third of your design empty.

Here’s how to apply this:

• Use grids to divide your layout into thirds.
• Leave one-third of the space empty to create balance.
• Avoid cramming too much text or imagery into a single area.

Remember, white space isn’t wasted space—it’s what makes your design feel clean and professional.

4. 3 levels of hierarchy: guide the viewer’s eye

Good design isn’t just about looking pretty—it’s about communication. To make your message clear, use three levels of hierarchy:

1. Headlines: The largest and boldest text, designed to grab attention.
2. Subheadings: Slightly smaller text that provides context or breaks up sections.
3. Body text: The smallest text, used for detailed information.

This structure helps your audience quickly scan your content and understand the key takeaways.

5. 3 sizes for elements: create contrast

Contrast is what makes a design visually appealing. One easy way to achieve this is by using three distinct sizes for your design elements:

• Large: For the most important elements, like headlines or hero images.
• Medium: For supporting elements, like subheadings or secondary visuals.
• Small: For details, like body text or icons.

This approach creates a sense of balance and ensures your design doesn’t feel flat.

6. 3-second rule: simplify your message

In the fast-paced world of B2B, your audience doesn’t have time to decode complex designs. That’s why your design should communicate its main message in 3 seconds or less.

Here’s how to achieve this:

• Use clear, concise headlines.
• Highlight key points with bold text or visuals.
• Avoid clutter—less is more.

If your design takes longer than 3 seconds to understand, it’s time to simplify.

Why the rule of 3 works

The rule of 3 isn’t just a random guideline—it’s rooted in psychology. Our brains are wired to process information in groups of three. It’s why we remember phrases like “stop, drop, and roll” or “life, liberty, and the pursuit of happiness.”

By applying the rule of 3 to your B2B design, you’re making it easier for your audience to process and remember your message. And in a world where attention spans are shrinking, that’s a huge win.

Final thoughts: design made simple

The rule of 3 is your shortcut to better B2B design. Whether you’re working on a presentation, a social media post, or a landing page, these principles will help you create designs that are clean, professional, and effective.

Here’s a quick recap:

• Use 3 fonts max for consistency.
• Stick to 3 colors max for balance.
• Divide your space into thirds to embrace white space.
• Apply 3 levels of hierarchy to guide the viewer’s eye.
• Create contrast with 3 sizes for elements.
• Simplify your message with the 3-second rule.

But here’s the thing: while the rule of 3 is a fantastic thumb rule, it’s not a one-size-fits-all solution. Every brand, audience, and project is unique, and sometimes breaking the rules is what makes a design stand out. That’s where we come in.
