Headline Google Calendar

With over 500 million users Google Calendar is one of the most used products in the world. During my four years with the team, I guided them through two major design overhauls and worked on numerous Interaction and Visual Design projects across the mobile and desktop apps.

During my time with Google Calendar, I led the design system efforts for both mobile and desktop platforms. This included the implementation of two major design updates: Material Design 2 and the recent Material You (Material Design 3).
Throughout these multi-year efforts, we wanted to improve cross-platform consistency to create a more cohesive user experience. Furthermore, we aimed to create a distinct visual language for Google Calendar to strengthen brand recognition and user association with the product.

As Google Workspace products became increasingly integrated, a unified design system was crucial to break down silos and create a holistic user experience across the suite of products. 

The initial vision for Google’s biggest design update in years, Material You, only included a basic idea for the overall look and feel. Therefore, my main challenge for this effort was to not only lead the implementation of the new design system within Google Calendar, but to also collaborate with designers across the Workspace and Material Design teams to define the new visual language. To achieve this, I co-led a working group spanning eight Workspace teams, facilitated workshops with product managers and engineers, and developed internal design guidelines and tooling. The biggest hurdle in all of this? Over 500 million users rely on Google Calendar regularly. Therefore, making changes without disrupting established workflows was a top priority.

The task: Create a consistent Calendar design framework

The challenge: How to embrace the Google brand identity without giving away Calendar’s visual character?

Material Design’s core principles were key to achieving a strong brand identity and consistent user experience. These included leveraging white space as an active design element and expressing Google’s brand through componentry.

Google Calendar prioritizes clean layouts by embracing generous white space. This eliminates the need for visual containers and unnecessary dividers. Instead, the design relies on clear element alignment and an adaptive spacing system to ensure a structured user interface across all platforms.

However, to truly elevate Calendar's brand identity within the suite, we prioritized core Calendar elements like the grid and today indicator.

While the importance of a unified today indicator seemed self-evident, numerous design variations previously existed across desktop, mobile, emails, and marketing materials. The new design streamlined the user experience by providing a clear visual focal point within the app.

This achievement wasn't solely reliant on UI design; The biggest challenge for me was to achieve consensus among stakeholders and ensure consistent technical implementation across multiple teams.

By leading a design collaboration across several teams, a central design library was born, extending beyond Calendar-specific components to share and reuse elements across all Workspace products. I helped develop a pipeline for creating, maintaining, and adding components to the library, which became the cornerstone of the visual design framework, ensuring a consistent user experience.

The Calendar library is used by over 200 teams across Google, with more than 20,000 component insertions per week.
And since a design library in Figma only gets you so far, I closely collaborated with engineers on Android, iOS and the web to actually implement components and design tokens into the product.

DARK THEME

The frequently requested dark theme was a natural next step for Google Calendar. I led both Interaction and Visual Design for the project. The key challenge? Google Calendar's functionality relies heavily on color distinction – and the product's vibrant color scheme could lead to increased eye strain in low-light conditions.

To address usability concerns in low-light environments, I explored various proposals for color mapping between light and dark mode. The final solution – a subtle yet effective approach – maintained consistent color rendering across most setups. This was achieved through dynamic adjustments to color saturation and perceived brightness, ultimately reducing eye strain and significantly improving usability in challenging lighting conditions.

The Material Design team showcased our system at Google I/O , and it was later adopted by other products like Google Home.

iOS WIDGET

With Apple introducing widgets on iOS we had the unique opportunity to design a tailored experience for Google Calendar from the ground up. I led the entire project from the UX side – from initial vision and feature set definition through to implementation.
The final widget came in two sizes, offering essential features for users to manage their day without needing to open the full app. The widget seamlessly integrated with the Google Workspace environment, providing users with one-tap actions to join meetings, initiate chats, and create new events or tasks – all without ever leaving their home screen.

Google aimed to launch all their widgets on day one – which required close collaboration with other designers, project managers and engineers across the company. Furthermore, Apple’s own Calendar widget obviously had a head start. We defined a feature set which clearly differentiated Google Calendar as a product and provided even more value to our more business-focussed target audience.

As with all other design efforts within the Workspace and Google ecosystem this project required close collaboration across teams and disciplines. While each implementation had its own personality, key UX and UI patterns were shared on both the design and engineering side. This collaborative approach significantly reduced development timeframes, enabling us to deliver the entire suite of widgets within a mere few weeks.

While each Google widget has its own personality, we designed key components in partnership for both the design and engineering side, thereby significantly reducing development times.

Moving beyond a static list of events, the widget dynamically adjusts its rendering throughout the day. This also includes intelligently grouping calendar entries to make optimal use of the limited space available.

Color labels

Many Calendar users rely heavily on color coding their events for a more structured scheduling experience. To better support this behavior we explored various ways to add semantic meaning to calendar entries.

The challenges: right from the outset, we knew that we wouldn’t be able to launch color labels on all platforms simultaneously. Additionally, users often sync their calendars with other products like Outlook or by sharing .ics files. In essence, we had to make sure that the users’ workflows didn't break even if the feature was not supported on every client.

The final solution was straightforward and intuitive, primarily due to its inherent simplicity. Rather than introducing a completely new labeling mechanism, we capitalized on the existing calendar color system, enabling users to assign custom names for better organization. This approach ensured cross-platform and cross-calendar-client compatibility, as labels could be effortlessly included or excluded within .ics files.

With color labels we saw an additional opportunity: a few months earlier the team had introduced Time Insights – a new way to help users better understand how they spend their time. Initially, Time Insights focused solely on event types and meeting attendees. We recognized the potential for even greater user value and strategically expanded the feature to include breakdowns based on user-defined color labels.

Google Workspace Rebrand

As Google's work tools achieved tighter integration and a wealth of new features, the G Suite brand no longer fully captured their potential. To clearly communicate this evolution and position the suite as the premier productivity solution, we partnered with Wolff Ollins to launch Google Workspace.

Together with Visual Designers from across the org I closely collaborated with the agency to guide the process from the product side. This included briefings and feedback check-ins, but also design solutions for specific use cases, such as Calendar's dynamic logo, system icons, and favicons. Additionally, I partnered with an external motion designer to bring Calendar's logo to life – not just for marketing purposes, but also for the app's splash screen.
