The aim of international design is to create experiences that are equally usable, relevant, and meaningful across the globe to amplify the voices of global users.
There are roughly 200 countries and 6500 spoken languages in the world. Culture is deeply rooted in our thinking patterns, and it affects how users interact with and benefit from digital experiences. International design is a complex challenge that goes beyond translation. Acknowledging cultural characteristics and differences is the first step to create richer, world-ready digital experiences.
Here, you'll find recommendations and guardrails for how to start creating user experiences that are scalable globally, and concepts to better understand how varied our user landscape is. Designing for a global audience is not an exact science, but by acknowledging the following issues, we take an important first step to develop more empathy towards our international users and build globally relevant user interfaces.
One of the biggest challenges of designing for a global audience is to create interfaces that can efficiently adapt to different languages that have different writing and reading systems, different grammar rules, different typographic convention, and translating content leads to textual content that can differ drastically in length.
When translating content to different languages, the length of the translated text is likely going to be very different — sometimes up to 300% longer than the original one. Text expansion is one of the main challenges of designing effective global user interfaces.
IBM Globalization Guidelines reported an interesting correlation between the number of characters in a text field and the amount of text expansion. These experimental values clearly indicate that shorter text fields are more susceptible to text expansion, and these values can help us predict the effect on our user interfaces.

|Characters||Max. estimated expansion||Likely mapping to:|
|Up to 10||300%||Buttons, dropdowns, tabs|
|11 to 20||200%||Labels, input fields|
|21 to 30||180%||Large headers|
|31 to 50||160%||Small headers, tooltips|
|51 to 70||140%||Short paragraphs|
Localized content and text expansion have a substantial impact on how user interfaces look and perform across different countries. It’s vital to create layouts that can efficiently flow with the textual content of different length and nature. Checking the readiness of a design solution across multiple languages can be time-consuming, so tools like World Ready (XD Plugin) can help you automate some of the process.
As imagery is closely related to society, culture, beliefs, religion, and political values, it’s extremely important to be careful and intentional about picking pictures for each region or even country.
It’s important to pick models who are dressed appropriately for the region. Editing of portraits also differs with facial manipulation and skin smoothing being popular in many Asian countries such as China and Korea. The amount of skin shown can also be considered too suggestive in some cultures.
Similarly, political, inspirational figures that are celebrated and extremely popular in the United States are likely to be unknown in some regions.
In general, it’s best practice to avoid religious symbolism, hand gestures, and political imagery, as regions may perceive them differently.
Photos of Tibetan monks are perceived in Western cultures as deeply spiritual. In China, on the other hand, Tibetan Buddhist monasteries are a symbol of a long religious and political dispute.
Seasonal content is greatly different country by country, and photography should reflect it accordingly. For example, there is a variety of celebrations, such as Thanksgiving, that are not meaningful in Asian countries, or interpreted in different ways.
Valentine’s day in Japan is quite unique from a western standpoint. The common roles are reversed and it’s the women who present gifts to significant others, usually chocolate or sweets.
It’s often said that the best way to experience a country is to learn and respect its customs. Similarly, when choosing imagery across different cultures, we need to be respectful and aware of different traditions and manners across different regions, and act accordingly.
Pictures like this one would likely represent “relaxation” in the United States, but are inappropriate in countries like Thailand, where you are not supposed to show the soles of your feet.
As mentioned in the Inclusive Design page, it’s important to not refer to objects by color, as users across countries perceive colors in different ways. Similarly, colors are perceived differently around the globe and carry different emotional, political, and cultural meanings.
Let’s consider an example: the design for a finance application. To display how certain stock options are performing, designers from the United States or Europe would likely use the color green to depict good performance and red to display stocks performing poorly. On the other hand, surprisingly, designers in China or Japan would likely take an opposite approach, and reverse the usage of these two colors.
While in the United States and most western countries the color red is often associated with the idea of error or danger. However, in eastern countries the color is tied to the concept of good luck and happiness.
White is a color tied to the concept of purity in western countries, but can be seen as a mourning color in countries like China. In Japan, purple is a color that expresses luxury and financial success, while in Italian popular culture is seen as a color that attracts bad luck. The list goes on.
In general, no color can be assumed to have a consistent meaning across cultures.
When approaching the design of user interfaces for a global audience, colors should not be the only indicator of a specific status or use case. It's always better to integrate with textual or other visual clues.
When designing promotional content, capturing the right tone and emotions from the local audience is key, and colors can have a big impact. It’s important to research specific markets from a cultural standpoint to choose the right creative decision.
Adobe Clean is our standard system typeface. Developed specifically for Adobe's brand identity and user interface design, it provides extensive language support. Please refer to the Typography page for an in-depth overview of our typography system.
Languages like Chinese, Japanese, and Thai use characters that are visually complex compared to the Latin ones.
The peculiar nature of these writing systems has an impact on the character size, which is usually slightly bigger than western typography.
To ensure good readability, it’s important to adjust the line-height value of paragraphs to create some extra breathing room between lines, and when necessary, increase interline spacing between characters. Similarly to text expansion, these differences can have an impact on the width and height of localized paragraphs.
Different cultures have varying expectations around volume of content. Japanese users generally prefer larger amounts of content and greater detail compared to North Americans, so content-heavy interface designers should consider the volume of content expected by these users. We recommend a modular design that allows for additional content. This is both for usability and user satisfaction of our products.
Using bold and italics to emphasize words or phrases is common in Western typography, but for certain languages it might not be the right way of highlighting content.
For example, languages like Chinese, Korean, and Japanese do not commonly rely on italicization because they lack oblique faces, and use alternatives like emphasis dots.
