Arabic Website QA: Five RTL Problems to Test Before Sign-Off
Short Answer
Most Arabic website bugs come from direction set in CSS instead of HTML, unisolated mixed text, blanket mirroring, untested forms and narrow mobile layouts. Test each before sign-off.
The Arabic homepage looks balanced in the design file. Then real content arrives: an English product name, an email address, a +971 phone number and a long order reference. Punctuation jumps to the wrong end, a label overlaps its value and the mobile menu slides out from the wrong side. None of this shows up in a mirrored screenshot approved during design.
This guide lists five right-to-left problems to test before you approve an Arabic business website in the UAE. Each one comes with the fix recommended by W3C internationalisation guidance or standard CSS. It is written for business owners and project managers, not only for developers. Bring it to your staging review and test every template with real content.
Is right-aligning text enough for an Arabic page?
No, right alignment only moves text visually and does not set the direction the browser uses. Arabic pages need the dir attribute set to rtl on the html element. W3C guidance says never to use CSS to apply the base direction.
The reason is practical: direction information must survive when stylesheets fail, load late or are stripped by email and reader tools. The HTML lang attribute should also say ar, so browsers, screen readers and translation tools behave correctly. Check the page source in the browser, not just the screen.
Quick Answer
Right-aligned text is not the same as right-to-left direction on an Arabic page for UAE visitors. W3C guidance says to set dir="rtl" and lang="ar" in HTML, never through CSS alone.
Why do phone numbers and English names scramble in Arabic text?
Mixed Arabic and English content triggers the Unicode bidirectional algorithm, which reorders characters by direction. Without isolation, a +971 number, an email address or a brand name can jump position or drag punctuation with it. The result often looks clearly broken to Arabic readers.
W3C recommends wrapping inserted text of unknown direction in a bdi element, or adding dir="auto" to the element holding it. This matters most for names from databases, order references and user reviews. Test those fields with real mixed samples from your own database, not lorem ipsum.
Quick Answer
Mixed Arabic and English text is reordered by the Unicode bidirectional algorithm and can scramble visibly. W3C recommends isolating inserted text with a bdi element or dir="auto" to stabilise order.
Should every element be mirrored on an Arabic site?
No, only elements that express direction or reading order should flip. Back and forward arrows, progress steps and breadcrumb separators usually mirror, while logos, media play buttons and checkmarks usually stay unchanged. Charts with time on the horizontal axis need a deliberate decision from the designer.
The cleanest build uses CSS logical properties, such as margin-inline-start and padding-inline-end, instead of left and right. Logical properties follow the document's text direction automatically, so one stylesheet serves both languages. Hard-coded left and right values are the most common source of broken spacing.
Quick Answer
On Arabic websites, mirror only directional elements such as arrows, steps and breadcrumbs, not logos or media controls. CSS logical properties like margin-inline-start adapt layouts automatically for right-to-left Arabic pages.
Why do Arabic forms fail even after translation?
Arabic forms fail because translated labels hide untested behaviour underneath. Email, website and phone fields usually need left-to-right input, even on an Arabic page, or the cursor jumps unpredictably. Validation messages, placeholders and required markers often stay in English or appear on the wrong side.
Test each form end to end in Arabic, submitting both valid and invalid data. Check that Arabic-Indic digits typed on a phone are accepted or converted where your system expects Western digits. Confirm the thank-you page, confirmation email and WhatsApp redirect also appear in Arabic.
Quick Answer
Arabic forms need left-to-right input for email and phone fields, translated validation messages and working digit handling. Test every form fully in Arabic, including its confirmation emails and thank-you pages.
What breaks on narrow mobile screens?
Mobile layouts expose hidden assumptions, such as menus that open from the left or carousels that swipe the wrong way. Arabic text can also need more line height, so tight headings clip letters or overlap. Horizontal scrolling often appears when one element keeps a fixed left offset.
Review every template at 360 pixels wide on a real mobile phone, in portrait orientation. Open the menu, swipe galleries, expand accordions and scroll tables with Arabic content loaded. Record defects against templates rather than pages, so one fix repairs every affected URL.
Quick Answer
Test Arabic templates at about 360 pixels wide on real phones, checking menus, carousels and line height. Log defects by template so each right-to-left fix repairs every affected page together.
Main Takeaways
Set dir="rtl" and lang="ar" in HTML, because W3C guidance says base direction never belongs in CSS. Isolate mixed English values, such as emails and phone numbers, with bdi or dir="auto". Mirror only directional elements, and build all spacing with CSS logical properties. Test forms, confirmation messages and mobile templates at about 360 pixels wide using real Arabic content before sign-off.
Making RTL part of your sign-off
Put these five checks into the project scope before design starts, not after launch complaints. Ask your developer to prepare a test page containing awkward real content: mixed names, long references, phone numbers and emails. Review it on a phone and a laptop in both languages. Approve templates only when both an engineer and a fluent Arabic reader are satisfied.
Search signals for the Arabic version are covered in our guide to bilingual website SEO signals. Many RTL checks overlap with our website accessibility basics for the UAE, especially forms and focus order.

FAQs
Questions readers usually ask next
These FAQs are written to match the topic of this post and to help readers move from understanding to action.
What does RTL mean in web design?
RTL means right-to-left, the reading direction used by Arabic, Hebrew, Persian and Urdu. An RTL website sets that direction in HTML so its layout and text flow correctly for readers.
Can one stylesheet support both English and Arabic?
Yes, when it uses CSS logical properties instead of fixed left and right values. The layout then follows each page's dir attribute without a separate Arabic stylesheet to maintain later.
Should Arabic websites use Arabic-Indic or Western digits?
Both appear across the UAE, so choose one convention and apply it consistently in content. Forms should accept whichever digits customers type and convert them where systems require Western digits.
Does WordPress handle RTL automatically?
WordPress supports RTL languages and loads RTL stylesheets when active themes provide them. Custom blocks, plugins and page builders still need testing, because many use hard-coded left and right spacing.
What is the bdi element used for?
The bdi element isolates a piece of text so its direction does not disturb the surrounding content. It suits usernames, product names and other inserted values of unknown text direction.
Which Arabic fonts work well on websites?
Choose a web font designed for Arabic with complete character coverage and readable weights at small sizes. Test it on Android and iPhone, because fallback fonts can change spacing noticeably.
Should the Arabic menu order be reversed?
The visual order flips automatically when page direction is right-to-left, so the first item appears on the right. Do not manually reverse menu items in HTML, or order breaks twice.
How do I test RTL without an Arabic speaker?
Developers can test structure, direction and mirroring with sample Arabic text from the client. Language quality, tone and reading comfort still need review by a fluent Arabic speaker before launch.
Do RTL bugs affect Arabic SEO?
Layout bugs do not change how Google detects language, which relies on visible content. They do hurt usability, trust and conversions from Arabic visitors who reach the page from search.
When should RTL testing start in a project?
Start once the first real template is built, not after every page is complete. Early testing lets developers fix shared components once instead of patching dozens of finished pages later.
