Difference between arabic 101 and 102 keyboard layout explained

Understanding the difference between arabic 101 and 102 keyboard layouts comes down to one physical key and a small shift in punctuation. The Arabic letters do not move between the two variants; what shifts is hardware standard and symbol placement.

The Arabic 101 vs 102 keyboard layout differences explained

Both variants use the same arabic letter positions. The numbers describe hardware standards, not a different alphabet or a different Arabic layout.

What the numbers 101 and 102 actually mean

The difference between arabic 101 and 102 starts with key count. A 101 keyboard follows the ANSI standard built around the English QWERTY base, while a 102 keyboard follows the ISO standard and adds one extra key.

• Key count standard: the 101 keyboard matches ANSI hardware, while the 102 keyboard includes the additional ISO key used on many European boards.
• Arabic layer: the arabic letter positions stay the same on both variants, so the script itself does not change.
• Symbols and punctuation: the difference comes down to where some marks and symbols sit, because ISO and ANSI handle those keys differently.

Windows 10 and Windows 11 usually surface arabic 101 and arabic variants by default, while the ISO-based option is available through language settings. As a result, the standard arabic keyboard most people encounter first is the ANSI-style version rather than the 102 variant.

The extra ISO key and structure of the layout

The structural change is simple. On an arabic 102 keyboard, there is an extra ISO key between the left Shift and Z. On an ANSI board, that key does not exist, which is why the arabic 101 layout is the correct match for that hardware.

If the selected input setting expects a key your board does not physically have, some symbols will land in unexpected places even though the Arabic letters remain correct. In practice, that mismatch shows up first on punctuation and secondary symbols rather than on the alphabet itself.

How arabic keyboard differs from english in both layouts

The letter arrangement is not a phonetic mirror of English, and the writing system runs right to left. Once you factor in bilingual use, that affects which legends appear on the keycaps and whether a single set covers both scripts legibly.

• Direction: Arabic text flows right to left, unlike English.
• Letter arrangement: letter positions follow long-established Arabic typewriter conventions rather than English sound or alphabet order.
• Extended characters: some arabic keyboard layouts use AltGr for additional symbols, diacritics, or less common characters.

Numerals add another layer. An arabic keyboard may show Eastern Arabic numerals or Western digits, but that choice is generally handled in software rather than by changing the core arabic 101 keyboard layout. For a physical reference on the keys themselves, Arabic keycaps present both scripts on one set.

Which arabic keyboard layout should you choose

The right choice depends on the board in front of you. If the physical keyboard is ANSI, use the arabic 101 keyboard. If it is ISO, use the 102 variant so the extra key and its punctuation mapping behave as intended.

For most learners, the arabic 101 layout is the practical starting point because teaching materials and common system defaults usually follow it. Moving later to ISO is straightforward, since the arabic letter positions do not change. A fuller keyboard layout guide is available in this Arabic keyboard 101 102 article, and this guide to Arabic bilingual keycaps covers ANSI and ISO compatibility for bilingual sets.

The difference between arabic 101 and 102 does not affect the alphabet. It affects the hardware fit and a few symbol locations.

Frequently asked questions

What is the difference between Arabic 101 and 102 keyboard?

The difference between Arabic 101 and 102 comes down to the physical keyboard itself: Arabic 102 is built for an ISO layout and adds one extra key between the left Shift and Z. Arabic 101 matches the ANSI standard instead.

Which Arabic keyboard layout should I use?

The right choice depends on the standard of your physical keyboard. If the board is ANSI, which is the usual format across the GCC, Egypt, and the Levant, use the Arabic keyboard setting for Arabic 101; if it is ISO, Arabic 102 is the correct match because of the extra key.

For learning and day-to-day typing, Arabic 101 is usually the safer default. Most typing materials assume that layout, and the letter positions remain consistent either way.

Does switching between Arabic 101 and 102 require relearning the keyboard?

Not much. Because the Arabic letter positions are identical, existing typing muscle memory carries over almost completely. Where it matters most is punctuation and symbol placement, including the extra key found on an 102 keyboard, rather than the Arabic alphabet layer itself.

On Windows, the layout can be changed through Settings → Time & Language → Language & region. Active layouts can also be toggled quickly with Alt + Shift.

The difference between Arabic 101 and 102 is not in the Arabic letters themselves but in the underlying layout, the extra ISO key, and the placement of punctuation.
