Choosing Arabic Fonts for Websites and Apps: A Developer's Guide

Choosing Arabic Fonts for Websites and Apps

Why is Arabic Web Typography Harder than English?

When setting up an Arabic interface, test the text direction, character rendering, and diacritics on the actual page:

Use the appropriate document direction, then test mixed Arabic and Latin text
Verify that the required characters and diacritics appear in the font itself
Font file size varies based on design, weights, and included characters
Test the font on the browsers and devices targeted by the site

Fonts That May Be Available on Some Systems

Fonts like Arial and Times New Roman may be available on some systems, but do not assume a specific font exists for all visitors. Add a fallback font list and test the text appearance when the primary font is missing.

For Windows:

**Arial**: Supported natively but its quality for Arabic is average
**Times New Roman**: For formal texts

Examples of Arabic Fonts to Test

**Noto Naskh Arabic** and **Amiri**: Compare them on long texts and required diacritics
**Cairo** and **Tajawal**: Test them on the site interface and different screen sizes

These are examples for comparison, not a ranking of the best; check the license and language coverage for each font from its source.

Methods for Embedding Arabic Fonts in a Website

Method 1: Using Google Fonts

```html

```

```css

body {

font-family: 'Cairo', sans-serif;

text-align: right;

}

```

Method 2: Embedding a Custom Font (@font-face)

```css

@font-face {

font-family: 'MyArabicFont';

src: url('/fonts/my-font.woff2') format('woff2'),

url('/fonts/my-font.woff') format('woff');

font-display: swap;

}

```

Method 3: CDN Fonts

The font can be loaded from an external service or hosted on your site. A CDN alone does not guarantee better speed; compare loading time, privacy, and reliability, and review the license terms.

RTL Rules for Developers

HTML Setup:

```html

```

The `dir` attribute determines the text direction in HTML; use it at the document or element level depending on the content.

CSS Setup:

```css

/* Global settings */

body {

text-align: right;

font-family: 'Cairo', sans-serif;

}

/* For English content inside an Arabic website */

.english-content {

text-align: left;

}

```

Set `dir="ltr"` on the English content element itself instead of relying on CSS styling alone.

Testing Flexbox with RTL:

```css

.container {

display: flex;

}

```

Set `dir="rtl"` on the container in HTML, then test the order and direction of elements on the actual interface.

Impact of Font on Site Speed

File Size and Performance Indicators:

A fixed size range cannot be generalized for an entire format; the size changes according to the font, number of weights, characters, and file preparation method. Check the actual file size and measure its impact on the page using it.

Choosing the format depends on target browsers, licensing, and generation tools. Compare the resulting file sizes instead of assuming one format is the smallest in every case.

Performance Optimization Techniques:

#### 1. Choose a Font Display Strategy

It determines `font-display` text rendering behavior while the font is loading. Review the options and choose what suits the interface; the following example uses `swap` and does not represent the most appropriate setting for every site.

```css

@font-face {

font-family: 'MyFont';

src: url('font.woff2') format('woff2');

font-display: swap; /* Show fallback text immediately, then swap when the font loads */

}

```

#### 2. Preload Critical Fonts Only

```html

```

#### 3. Subset Characters When Needed

A subset of characters can be prepared to reduce what is loaded, provided the license allows it and the set includes all letters and diacritics needed by the content.

Verifying Font Support for Arabic

Checking Loading Status:

```javascript

console.log(document.fonts.check('16px "MyArabicFont"'));

```

This function displays the font loading status, but it alone does not prove that every Arabic character or diacritic mark is present in it. Visually inspect the text, including ligatures and diacritics, and compare it with a fallback font.

Basic Characters for Testing:

"ب ت ث ج ح خ ص ض ع غ — write this to ensure full character support"

Comparison Examples by Site Type

These are starting points for testing, not a ranking or guarantee of suitability.

| Site Type | Fonts to Test | What to Test |

|-----------|------------|------|

| E-commerce | Cairo, Tajawal | Clarity of product names and prices |

| News Site | Noto Naskh | Reading long paragraphs |

| Corporate Site | Amiri, Scheherazade | Text clarity on target devices |

| Mobile App | Cairo, IBM Plex Arabic | Size and loading on mobile |

| Educational Platform | Noto Kufi | Clarity of letters and diacritics for the target audience |

Conclusion

Test the font on target texts and devices, and ensure RTL direction, character coverage, and licensing before publishing. Compare the resulting file sizes, and choose a loading strategy that suits the interface. xfontat pages display the available formats for each file; do not convert or redistribute the font unless its license allows it.
