Test a single Urdu word in right-to-left, and see how its letters join, which is the heart of how Urdu is written.
Quick Answer

What the Urdu RTL Word Tester Does
The Urdu RTL Word Tester shows one Urdu word in a right-to-left line and looks at how its letters join. It counts the letters, marks the ones that do not connect to the letter after them, and shows the word large so you can see the shaping clearly.
Joining is at the heart of how Urdu is written, since most letters change shape depending on their neighbours, and a few break the join.
Everything runs on your own device. Your word is never uploaded or stored, so it stays private while you test it.
How to Test a Word
- Paste your word. Enter one Urdu word.
- Look at the preview. See the word shaped in a right-to-left line.
- Check the joins. See which letters do not connect to the next.
- Copy or download. Copy the report, or save it as a text file.
How Letters Join
Most Urdu letters connect to their neighbours, changing shape at the start, middle, and end of a run of joined letters. This joining is automatic in the browser. A word is really a series of joined runs, broken wherever a non-joining letter appears.
Non-Joining Letters
A few letters connect to the letter before them but not to the one after. These are alef, dal, dhal, re, ze, zhe, wow, and their variants. After one of these, the next letter starts a fresh join. The tester marks these, since they explain where a word breaks into pieces.
Letters with Marks
A letter can carry a combining mark, a diacritic, stored as a separate character. The tester counts these marks apart from the letters, so the letter count is the number of base letters, not the marks that sit on them.

Who Uses This Tester
Type designers and students use it to study joining. Developers use it to check a word renders. Anyone curious about a word uses it to see its letters.
Accuracy and Limits
The tester counts the base letters, marks the known non-joining letters, and counts combining marks apart, and the preview uses the browser’s own shaping. The exact shapes depend on the font, so a word may look a little different on another device.
Good to know: for the code points of each letter, the Arabic script Unicode viewer lists them.
Your Data Stays Private
The tester runs fully in your browser with standard web technology. Your word is not uploaded or stored, and it is not sent to any analytics service. Only your star rating is sent, to record the tool’s rating. When you close the page, your word is gone.
Frequently Asked Questions
What does the Urdu RTL Word Tester do?
It shows one Urdu word in a right-to-left line, counts the letters, marks the non-joining ones, and shows the shaping in a preview.
Which letters do not join forward?
Alef, dal, dhal, re, ze, zhe, wow, and their variants connect to the letter before them but not to the one after.
Why does a word break into pieces?
Because a non-joining letter ends a joined run, so the next letter starts a fresh join. This is normal in Urdu.
Are marks counted as letters?
No. Combining marks are counted apart, so the letter count is the number of base letters.
