A design system is a collection of reusable components, guidelines, and standards that define how your digital products look and behave. Think of it as a shared language between your designers, developers, and anyone else who builds or maintains your digital presence.
If that sounds like something only Google and Airbnb need, it’s not. Any business with more than one digital touchpoint benefits from a system. Here’s why.
The problem it solves
Without a design system, every new page, feature, or campaign starts from scratch. A designer creates a new button style because they didn’t know one already existed. A developer builds a card component that looks slightly different from the one on another page. The marketing team creates landing pages that don’t quite match the main site.
Over time, small inconsistencies accumulate. The product starts to feel fragmented. Updating the brand means hunting through dozens of files and pages to find every instance of the old style. Quality drops because there’s no shared standard.
This isn’t a theoretical problem. I see it on almost every site we audit. Buttons in three different sizes. Headings in four different weights. Spacing that varies randomly from page to page. Not because anyone made a bad decision, but because there was no system to make good decisions easy.
What a design system actually contains
At its simplest, a design system includes colour definitions (primary, secondary, accent, semantic colours for success/warning/error), typography (font families, sizes, weights, line heights for each heading level and body text), spacing (a consistent scale, usually based on multiples of 4 or 8 pixels), and a component library (buttons, forms, cards, navigation, modals, and any other UI element that appears more than once).
A more mature system also includes interaction patterns (how things behave on hover, focus, click), accessibility standards (contrast ratios, keyboard navigation, screen reader requirements), content guidelines (tone of voice, writing conventions, terminology), and documentation that explains when and how to use each component.
The business case
Design systems save time and money. That’s the bottom line.
When a developer needs a button, they use the existing button component. They don’t design a new one, get it approved, build it, and test it. The work has already been done once and done well.
When you rebrand or update your visual identity, you change the system once and the changes flow through to everything that uses it. Instead of updating 50 pages individually, you update the design tokens and the components inherit the changes.
When you hire new team members, the system is their onboarding. They don’t need to reverse-engineer the design decisions from existing pages. The decisions are documented and available.
When you add new features or pages, they feel consistent with the rest of the product from day one. No design review meetings to catch inconsistencies. No QA cycles to flag visual bugs.
You don’t need to build Spotify’s design system
The scale of your design system should match the scale of your business.
A startup with a 10-page marketing site doesn’t need a 200-component library with Storybook documentation and versioning. They need a clear set of colours, fonts, spacing values, and a handful of reusable components. That might fit in a single Figma file and a CSS stylesheet.
A SaaS company with a complex product interface needs something more structured. Documented components with usage guidelines, coded equivalents, and a governance process for adding new components.
The point is to start with what you need now and build from there. A small system that people actually use is infinitely more valuable than a comprehensive system that sits in a folder nobody opens.
Common objections
"We’re too small for a design system." If you have a website and any other digital touchpoint (email templates, social media graphics, presentations), you benefit from consistent design standards. You don’t need to call it a design system. Just define your colours, fonts, and key components in one place.
"It will slow us down." The opposite is true. It feels slower at the start because you’re investing time in building the system. But once it exists, every subsequent project is faster because you’re not redesigning from scratch.
"Our designers will feel restricted." A good design system isn’t a cage. It handles the boring, repetitive decisions (what shade of blue, how much padding, what font size) so designers can focus their energy on solving actual problems. Constraints breed creativity.
"We’ll build one when we have time." You won’t. The best time to start a design system is during a project that’s already happening. Build the system as part of the work, not as a separate initiative.
How to get started
Start with an audit. Look at your existing digital products and catalogue the inconsistencies. How many button styles exist? How many shades of grey? How many different heading treatments?
Then define the basics: colour palette, type scale, spacing scale, and your most common components. Document them in a shared location where designers and developers can both access them.
Use the system on your next project. Refine it based on what works and what doesn’t. Add new components as you need them.
The system is never finished. It evolves with your product. That’s the point.
What we do
When we build websites, we build systems. Every project gets a set of design tokens, a component library, and documentation proportional to its complexity. It means the site is consistent on launch and maintainable after we hand it over.
