Direction is part of the interaction

An Arabic interface needs more than translated labels. Check reading order, directional meaning, mixed strings, regional formats, and the complete task with Arabic content. These ten mistakes are practical review prompts, not a claim that every Arabic-speaking audience has identical preferences.

Ten mistakes and their corrections

  1. Right-aligning text without setting direction. Set the document language and appropriate RTL direction. Alignment alone does not establish reading order or bidirectional behavior.
  2. Mirroring every icon. Mirror an icon when its directional meaning should reverse in the local interaction. Do not automatically flip logos, product imagery, or symbols whose meaning is independent of reading direction.
  3. Leaving navigation behavior in an accidental order. Check back, next, breadcrumbs, tabs, and progressive steps as a coherent flow. Test the expected behavior instead of relying on a blanket CSS transform.
  4. Letting mixed strings reorder unexpectedly. Isolate email addresses, order references, and unknown-direction strings with appropriate HTML direction handling. Test punctuation around them.
  5. Using placeholder Arabic. Test actual headings, messages, names, and addresses. Artificial short strings conceal wrapping and content problems.
  6. Reusing Latin spacing unchanged. Check the Arabic typeface, line height, size, and weight at realistic densities. Avoid letter-spacing rules that damage connected Arabic text.
  7. Assuming one format for all markets. Confirm the expected date, number, currency, phone, and address formats for the product's supported regions.
  8. Changing only the visible form layout. Review label association, focus order, error placement, autocomplete, and the direction of mixed-content fields.
  9. Switching language and losing progress. Preserve the current route, basket, or appropriate form state when users change language. Explain any information that cannot be preserved.
  10. Skipping Arabic usability testing. Test real tasks with relevant Arabic-speaking users, including assistive-technology testing where feasible. Translation review and usability review answer different questions.

Review a complete task

Choose one journey such as finding a product and completing an address. Inspect each transition in Arabic, including empty, loading, error, and confirmation states. Compare visual order with keyboard and reading order. A polished first screen can still lead into an untranslated or confusing recovery state.

Record the problematic string or component and its context. A reference such as “RTL is broken” is difficult to act on; “the order number and closing punctuation reverse in this confirmation message” gives the team a reproducible case.

Before release

  • Review direction at document, component, and mixed-string levels.
  • Use logical spacing properties where the layout should follow direction.
  • Test long Arabic labels alongside Latin codes and phone numbers.
  • Verify keyboard focus, screen-reader labels, and error announcements.
  • Check both language versions after component changes.
