Designing Websites for Arabic and RTL Languages

For businesses in Bahrain and the Gulf, supporting Arabic is not optional. It is the language your customers read, search in and expect to interact with. A bilingual website is not just an English site with translated text. It requires a fundamentally different approach to layout, typography, navigation, SEO and content management.

This guide covers everything you need to design an effective bilingual Arabic and English website. We will look at layout mirroring, Arabic font selection, information architecture for two languages, hreflang implementation, Arabic-specific SEO and the most common mistakes that make bilingual sites feel like an afterthought.

RTL layout fundamentals

Right-to-left layout mirrors the entire visual flow of an English site. The navigation shifts to the right side of the screen, text aligns to the right, the logo is on the right, and the reading order moves from right to left. If your design team starts from an English wireframe and simply translates the content, the layout will feel unnatural to Arabic readers.

The simplest and most sustainable approach is to use CSS logical properties. Instead of hardcoding left and right values, use inline-start and inline-end. The browser automatically interprets these based on the direction of the content. For example, margin-inline-start replaces margin-left in LTR mode and becomes margin-right in RTL mode. Padding-inline-end replaces padding-right in LTR and becomes padding-left in RTL.

Set the dir attribute on the html tag to rtl for Arabic pages and ltr for English pages. With logical properties in your CSS, most layout adjustments happen automatically. Flexbox and CSS Grid both support logical properties natively, making them the preferred layout methods for bilingual sites.

Arabic typography and font selection

Arabic script is cursive, meaning letters within a word are connected. The shape of each letter changes depending on its position in the word: initial, medial, final or isolated. A font that does not support all four letter forms and the full range of ligatures will render Arabic text incorrectly or with visible gaps between letters.

Google Fonts offers several excellent Arabic typefaces that are free to use and optimised for screen rendering. Noto Sans Arabic is a versatile choice that supports the full Arabic character set including Quranic marks and Arabic sign language. Cairo has a distinctive geometric style suitable for headings and display text. Almarai was designed specifically for digital reading with clear, open letterforms and excellent readability at small sizes. IBM Plex Sans Arabic brings a clean, modern aesthetic that pairs well with Latin typefaces.

A critical consideration is that Arabic text typically needs a larger font size than English text for equivalent readability. The cursive nature of the script and the presence of diacritical marks require more vertical space. Plan for Arabic body text to be approximately 10 to 20% larger in font size than the English equivalent. Line height should also be increased to prevent diacritics from overlapping with the line above.

When pairing Arabic and English fonts, choose typefaces from the same design family or complementary designs. Noto Sans Arabic pairs naturally with Noto Sans. IBM Plex Sans Arabic matches IBM Plex Sans. Mixing a traditional Arabic font with a modern English font creates visual tension that makes the site feel disjointed.

Bilingual information architecture

Decide how the English and Arabic versions of your site relate to each other before you write any code. The standard approach is a language switcher in the header that toggles between versions. Each version must have its own URL structure with clear, consistent patterns.

Using subdirectories with language codes is the recommended approach: yourdomain.com/en/ for English and yourdomain.com/ar/ for Arabic. This keeps both versions under the same domain, consolidates SEO authority and simplifies analytics tracking. Subdomains like en.yourdomain.com and ar.yourdomain.com also work but split SEO authority across domains.

The language switcher should persist across sessions. If a user selects Arabic, every page they visit for the rest of their session should remain in Arabic until they explicitly switch. The switcher should be clearly labelled in both languages: English and العربية. Place it in a consistent location, typically in the header or the main navigation bar.

Content that exists in one language but not the other creates a poor user experience. Decide how to handle pages that have not been translated. Options include hiding the link in the language version where content does not exist, showing a placeholder, or redirecting to a main page. Consistency is more important than any specific approach.

Hreflang tags for multilingual sites

Hreflang tags tell search engines which language version of a page to show in search results for a given language or region. Without hreflang tags, Google may show the wrong language version to users, causing confusion and increasing bounce rates.

Every page on your site should include hreflang tags in the HTML head or in the XML sitemap. The tag points to the English version, the Arabic version and a default fallback version. Use hreflang=en for English content, hreflang=ar for Arabic content and hreflang=x-default for the fallback language, typically English.

Each language version must link to all other language versions using reciprocal hreflang tags. If the English page at /en/about/ links to the Arabic version at /ar/about/, the Arabic version must link back to the English version. Broken reciprocal links cause search engines to ignore your hreflang annotations.

Hreflang tags can include region subcodes for country-specific content. For example, hreflang=ar-BH targets Arabic speakers in Bahrain while hreflang=ar-SA targets Arabic speakers in Saudi Arabia. Use region subcodes only when the content differs by country.

Arabic SEO considerations

Arabic SEO follows the same fundamental principles as English SEO but with important differences in execution. Keyword research must account for the difference between Modern Standard Arabic and local dialects. The word for car is sayara in MSA but varies across Gulf dialects. A Bahrain business targeting local customers should use local vocabulary where appropriate.

URL slugs can use Arabic script or transliterated English. Google handles Arabic URLs correctly and displays them in search results. However, some social media platforms and email clients may not handle Arabic URLs correctly, and users may struggle to type or share them. Transliterated English slugs provide a practical middle ground.

Meta titles and descriptions in Arabic must be crafted carefully. Search results display Arabic text right-to-left, which can cause awkward visual rendering when the title contains numbers, dates or English words mixed with Arabic. Test how your titles and descriptions appear in search result previews and adjust the wording to avoid broken visual flow.

Arabic content indexing requires proper language declaration. Use the lang attribute on the html tag and ensure your CMS sets the correct language metadata. Arabic text without proper language declaration may be processed with the wrong stemming algorithm or character encoding.

Common mistakes to avoid

Translating the English design. The most common mistake bilingual sites make. An English wireframe translated into Arabic creates a left-to-right reading experience for Arabic users, which is confusing and unnatural. Design the Arabic layout independently, starting from the right edge of the screen.

Missing bidirectional support. Arabic pages frequently contain embedded English text such as brand names, technical terms and addresses. Without the HTML bdi element to isolate the embedded text, the browser may render the mixed-direction content incorrectly, with punctuation and numbers appearing in the wrong position.

Hardcoding left and right in CSS. Using left, right, margin-left, padding-right and similar directional properties in CSS creates a maintenance nightmare for bilingual sites. Every RTL page needs overrides for every directional property. Use logical properties and let the browser handle direction changes.

Forgetting about mirrored imagery. Images containing directional elements such as arrows, progress indicators, timeline graphics or hand gestures need mirrored alternatives for Arabic versions. A right-pointing arrow indicating forward action in English points in the wrong direction for Arabic readers.

Neglecting form design. Arabic form labels align to the right, input text should also align to the right, and the submit button should be on the right side of the form. Form validation errors must also respect the reading direction. Testing forms with real Arabic input is essential before launch.

Testing a bilingual website requires more than just checking that the language switcher works. Each language version should be tested independently by native speakers who can evaluate the naturalness of the layout, the quality of the translation and the appropriateness of the cultural references. Automated testing cannot catch subtle issues like unnatural phrasing, culturally inappropriate imagery or incorrectly rendered bidirectional text. Budget for professional testing of both language versions before launch.

The choice between Modern Standard Arabic and local dialect depends on your audience and brand voice. MSA is understood across the entire Arabic-speaking world and is appropriate for formal business communication. Local dialects in Bahrain, Kuwait, Saudi Arabia and the UAE differ in vocabulary, pronunciation and expression. Using local dialect can increase engagement but may also limit your reach to other Arabic-speaking markets. Many businesses use MSA as the primary Arabic language and incorporate local terms where contextually appropriate.

Maintaining a bilingual site is an ongoing commitment. Every new page, blog post and product listing must be created in both languages. Content that exists in only one language creates a fragmented user experience and can frustrate users who expect the full experience in their chosen language. Have a content production workflow that produces both language versions simultaneously and a review process that catches inconsistencies between versions.

For businesses in Bahrain that serve both Arabic and English speaking customers, a well-executed bilingual website is a competitive advantage. It signals that you respect and cater to both audiences, which builds trust and credibility. A poorly executed bilingual site with broken RTL layout, machine-translated content or inconsistent navigation can actually damage your brand perception.

Font loading strategy is particularly important for Arabic websites. Arabic fonts are typically larger file sizes than Latin fonts because they contain more glyphs and ligatures. Loading both an Arabic font and a Latin font on the same page doubles the font loading overhead. Use font subsetting to include only the characters you actually need, and use the font-display CSS property to control how the browser handles font loading. A fallback font strategy ensures that text is readable even before the custom fonts have loaded.

Testing tools for RTL layouts have improved significantly in recent years. Browser DevTools allow you to change the document direction and test how your layout responds. Browser extensions like RTL Tester can mirror any website to preview the RTL experience. However, nothing replaces testing on real devices with real Arabic content. Set up a test environment where you can view your site in both languages with representative content before launch.

Consider the user experience of language switching carefully. The language switcher should be prominently placed, typically in the header or top navigation bar. It should clearly indicate the current language and the available alternative. Using native language names Arabic and English is more user-friendly than using flags, because flags represent countries rather than languages and can be confusing for countries with multiple official languages.

Performance considerations also apply differently to bilingual sites. Loading two sets of fonts, two sets of translated content and potentially different layouts for each language increases page weight. Implement lazy loading for the secondary language content if it is not immediately visible. Use efficient font loading strategies and consider whether you can share CSS between language versions with only direction-specific overrides rather than maintaining entirely separate stylesheets.

Social media integration for bilingual sites requires attention. Social sharing previews, Open Graph tags and Twitter cards must be configured separately for each language version. The preview image, title and description that appear when someone shares your Arabic page should be in Arabic, not English. Configure your Open Graph tags dynamically based on the current language and verify the output using social media debugger tools available from each platform.

Analytics tracking for bilingual sites needs careful setup. Set up separate view filters in Google Analytics to segment traffic by language. Track language switcher usage to understand how visitors interact with your bilingual interface. Monitor bounce rates and engagement metrics separately for each language version to identify whether one version underperforms and needs optimisation. Data-driven decisions about your bilingual experience are more effective than assumptions about what your Arabic and English audiences want.
