Case Study: Multi-Country Typeface Evaluation for a Global Client

Client: Anonymous (Global Brand Rollout)

Problem
A global company was preparing to introduce a new typeface family to replace its existing corporate type across digital products, print, and international markets. Because the rollout would reach millions of readers in multiple regions, the client needed to ensure the fonts would:

Perform reliably across languages and writing systems.

Support both short-form UI text and long-form reading.

Work for readers of different ages and visual abilities.

The company sought independent validation before making the typeface a cornerstone of its brand identity.

Solution
Typ designed a multi-site, multi-language study involving participants in five countries: Brazil, Denmark, Germany, Spain, and the United States.
Two controlled experiments were conducted:

Visual Acuity Study: Measured the critical print size (the smallest readable size) across multiple font styles and sizes ranging from large display text to small UI text.

Reading Performance Study: Tested fonts in continuous reading tasks, with participants asked to locate words in running passages, capturing both speed and comprehension.

Over 130 participants were recruited across regions, representing a range of ages. The methodology ensured cross-cultural reliability, while also accounting for age-related reading differences.

Outcome for the Client
The client received a confidential report providing:

Clear evidence on the minimum recommended sizes for safe legibility across contexts.

Guidance on which typeface variants to prioritize for UI, display, and long-form text.

Region-specific insights on how age and language influence readability.
