Right-to-Left (RTL) UX Design Considerations

When we think about designing digital experiences, most of us default to Left-to-Right (LTR) languages like English. However, millions of people around the world read and write in Right-to-Left (RTL) scripts such as Arabic, Hebrew, Persian, and Urdu. Ignoring RTL design not only alienates a significant audience but can also harm accessibility and usability. Creating RTL-friendly interfaces ensures inclusivity and a seamless user experience across cultures.

Why RTL Design Matters


According to estimates, over 300 million Arabic speakers and 9 million Hebrew speakers use RTL scripts daily. For these users, websites or apps that don’t properly support RTL text feel awkward, confusing, or even unusable. By addressing RTL considerations, brands can expand their reach globally, improve accessibility, and demonstrate cultural sensitivity.

Key RTL UX Design Considerations

1. Mirroring Layouts


In RTL design, the entire interface often needs to be mirrored. For example:

Navigation bars move to the right side.

Progress indicators flow from right to left.

Buttons such as “Next” and “Back” swap positions.
The goal is to make the design feel natural for RTL readers, where the primary action should align with the reading flow.

2. Typography and Fonts


Not all fonts support RTL scripts properly. Designers must select fonts optimized for RTL languages to avoid broken characters or poor readability. Line height, kerning, and character spacing should also be adjusted, as Arabic or Persian scripts often have more curves and connections compared to Latin characters.

3. Text Alignment and Wrapping


Text alignment defaults to the right in RTL scripts. Designers must ensure that text wrapping and truncation don’t cut off critical parts of a word. Proper testing with long strings of Arabic or Hebrew text is crucial for maintaining clarity.

4. Icons and Symbols


Some icons are direction-sensitive. For example:

A forward arrow should point left in RTL layouts (opposite of LTR).

Breadcrumb trails should reverse direction.

Play buttons, sliders, and timelines should flow from right to left.
However, not all icons need mirroring—universal symbols like a gear for settings or a magnifying glass for search remain unchanged.

5. Forms and Inputs


Input fields must adapt properly to RTL typing. Numbers and mixed text (like phone numbers or email addresses) often remain LTR even in RTL contexts. Designers should handle these scenarios carefully to avoid misalignment or confusion.

6. Consistency Across Platforms


Users often switch between devices and platforms. An app that supports RTL on mobile but not on desktop can frustrate users. Consistency in layout, alignment, and behavior across platforms ensures trust and usability.

7. Testing with Native Speakers


No matter how carefully you design, testing with actual RTL users is essential. They can quickly spot cultural nuances, misaligned layouts, or confusing flows that non-native designers might miss.

Conclusion

Designing for RTL languages isn’t just a technical adjustment—it’s a cultural commitment. By mirroring layouts, choosing RTL-friendly fonts, aligning icons correctly, and thoroughly testing, UX designers can create inclusive and user-friendly experiences for millions of users worldwide. Ultimately, supporting RTL is not just about accessibility—it’s about respect, inclusivity, and creating global digital products that work for everyone.
