Last Updated on June 10, 2024 by UX World

What Are UI Design Guidelines?

While working on UI design, there is a need to follow a few principles and guidelines that help you design a standard and consistent experience throughout your products.

UI design guidelines define the best design practices of different UI components. Also, they describe the behavior of these components by providing real examples.

These guidelines are usually decided at an organizational level and equally helpful for all team members including designers, developers, and testers.

“A guideline is a visual language communicating the design goals to the team, it is important to make sure that everyone can understand it and to enforce its usage.” — Yuki Gu

A few popular organizations have published their guidelines for audiences across the world. These include Google, Microsoft, Apple, and many others.

This is helpful for companies and individuals who create apps and plug-ins for them. Also, anyone can customize and use these guidelines as per their requirements.

Why are UI Guidelines Important?

“User interface is easy to make a mess out of. You can start a project with one style and end with another. It doesn’t matter if you are a guru or just dabbling, inconsistencies in the design will most probably arise. Don’t Worry! There is an easy solution: UI guidelines.” — Yuki Gu

Principles and guidelines are defined and followed in the UX design process for several reasons.

• They enforce consistent experience throughout your products.
• In addition to specs of UI components, guidelines also describe best practices. It makes it easier for a reader to decide about the right choice.
• They make learning easier. New members are trained in UI standards and behaviors with a little effort.
• Designers don’t have to create specs each time they design a feature.
• Developers don’t have to wait for specs. They can refer to guidelines and build interfaces.
• It is convenient to update guidelines based on new UI standards and trends and update your designs accordingly.

Hence, if you want to design a cohesive and consistent experience across your products, you must have a set of guidelines to follow.

Types of UI Guidelines

Based on their usage, UI guidelines can be categorized as follows.

Style

Style guidelines define the visual expression of an organization that it presents to the world. Every organization has its style guide which is used to build logos, colors, icons, and typography.

Layout

Layout guidelines define the overall structure of the interface. UI can be designed using a grid layout or list layout.

This section of guidelines also contains the behavior of responsive design.

UI Components

These guidelines provide specs and usage of UI components that display on the interface and a user interacts with them.

UI components include input controls, windows, dialogs, panels, menus, views, scrollbars, buttons, and other similar items.

Text

Textual guidelines cover the tone and style of text to be used on UI. The text should be understandable for different cultures and audiences.

Text specs like font size, color, and style are part of these guidelines. Text displays on the UI as fields, labels, messages, and information for users.

Interaction And Behavior

Types of interaction (click, gesture, voice) that a user performs with the design, and the system response to these interactions are part of these guidelines.

Platform

Platforms are changing rapidly and websites and apps are being developed for mobile, wearable, and auto car devices in addition to conventional desktop systems.

The UI guidelines of an organization cover details of all types of supported platforms and resolutions.

Accessibility

Designing an accessible system requires a specific set of guidelines for different types of disabled users so that they can access the design like a normal user.

Patterns

Reusable design patterns are included in UI guidelines. These patterns define behavior for certain controls.

A few examples are navigation, search, forms, data formats, states, and pagination.

Resources

Guidelines have a collection of resources that can be used while designing a system.

These resources contain layout templates for multiple devices, icon sets, font libraries, UI components, and color palettes.

How To Create UI Guidelines?

There are two approaches to creating UI guidelines.

1. Using Your Existing Products

If your organization has a detailed product, review it, extract guidelines from its design, and document them.

Add any required improvements in product behavior in the guidelines. Later, existing products can be updated.

2. Customizing Available Guidelines

Use existing guidelines of an organization like Google or Microsoft, and customize them as per your design requirements.
