What is a Design System, and Why Do I Need One?

As websites grow, maintaining a consistent, cohesive experience can become increasingly difficult. Teams change, content evolves, and small design decisions start to add up, often leading to inconsistency over time. This is especially true for organizations managing large, content-driven sites with multiple contributors.

At Reaktiv, we think about scalability not just in terms of infrastructure and performance, but in how a site looks and feels as it grows. How do you ensure that design and usability remain consistent, clear, and cohesive over time?”

A design system is the answer! It is a collection of visual rules and definitions for how your site looks, behaves, and scales. We create design systems as part of our process for many of our builds, and have found it to be tremendously helpful for not only our design and development teams, but most importantly, for our clients and their editorial teams.

What is a design system?

A design system is a library of documented styles, components, and patterns that can be reused by design, development, and editorial teams. Defined styles for things like fonts provide a consistent base for everything on the site, and components like buttons can be mixed and matched to create patterns and layouts.

Most design systems have three parts:

Style guide

The style guide provides examples of the base typography, colors, icons, and other styles to be used on the site. These styles are the basic “rules” that developers can implement in the code, like the color, font, and size for each heading (H1-H6) element. This ensures that every page on the site has the same visual foundation, creating a cohesive experience as users move through the site.

Component library

These styles are then used to create components: reusable elements that can stand alone or be put together in different patterns and templates. Google’s Material Design 3 system is a helpful reference for common components, including:

• Buttons
• Input fields
• Menus
• Cards
• Alert bars

Since these are likely things that you use in multiple places on your site, having a single, reusable look and feel for each of them will ensure that your site feels cohesive and consistent.

Pattern library

Finally, components can be combined to create patterns: templated sets of components. For example, this Subscribe CTA pattern from our redesign for Upworthy:

This pattern, a Subscribe CTA, includes:

• H3 style
• Link style
• Input field
• Background color style

Patterns must be well-defined so it is clear when, how, and why they should be used. Each pattern should have:

• Unique name
• Basic rules for usage – Can this pattern be used anywhere on the site? Should it always be paired with another pattern?
• States – How does a button change on hover, for example?
• Variables – How, if at all, can this component be changed? For example, in the Subscribe CTA above, is there an alternate color palette where the background is black and the text is white?

With well-defined patterns and components, building a new page is just a matter of mixing and matching components and patterns within your page layout. This way, you get the flexibility to choose from a variety of content display options, along with the consistency of a coherent look and feel.

Why do I need a design system?

A design system brings consistency, efficiency, and organization to both design and development. This is important when building out a site, but it becomes even more critical when it’s time for content managers and site owners to take over and manage the site day-to-day.

With WordPress’ Full Site Editing, Reaktiv is able to directly translate the design system into blocks, patterns, color palettes, and other styles. This way, content managers have the flexibility to create their own content and layouts while still staying within the guidelines of the design system.

For example, let’s say you’re regularly building landing pages that have a call to action, like registering for an event. Calls to action typically include text and/or images alongside a button, but these can be laid out in a million different ways and use different styles, colors, and fonts.

With a design system, we can create a reusable call to action pattern, like this version we did for GOOD:

This pattern can be added to any post or page with one click, and the specific layout, colors, fonts, and hierarchy are all pre-set. All the editorial team has to do is swap out the content.

How do I create a design system?

You probably already have everything you need to create a design system, but it’s just scattered and not-so-defined. Start with the style guide: any brand documentation that you already have should define (or help you define) base styles like typography and colors.

Then, move on to components and patterns by identifying the commonly used UI elements throughout your site. For example, buttons, CTAs, accordions, and newsletter sign-ups. You can track them by taking screenshots and noting where they appear.

Once you’ve identified these elements, you’ll need to consolidate them into single, standardized components and patterns. This could mean standardizing one of the existing versions or working with design to create a new one. One word of advice: Be ruthless! Start small and you can always add more components and patterns if and when you really need them.

Finally, document your components and patterns as part of the design system and commit to using them as documented. You can then replace any flagged versions of content on your site to ensure consistency between older and newer content.

How do I maintain a design system?

The most critical and difficult part of maintaining an effective design system is actually using and staying within the design system. It’s so easy to start making tiny, “one-time” tweaks that ultimately make the design system fall apart over time.

When someone requests a change to a design system style, component, or pattern, think critically whether it is actually needed. Is there another component or pattern that can be used for what they’d like to do? Will this functionality be needed in the future, or is it just a one-time thing?

Whenever possible, consider creating variants of existing components and patterns as opposed to entirely new and different versions. For example, in our redesign for GOOD, this Featured Stories pattern always displays the article category under the featured image:

A variant of this pattern could hide these categories if desired. This could be documented as a variant in the design system to show how the pattern should look with categories hidden, and developers could add a new option for hiding or showing the categories.

Wrapping Up

Even a basic design system can significantly improve consistency, scalability, and team efficiency. Organizations with mature design systems often see faster editorial and development cycles and more consistent user experiences across teams.
