FAQs about Readable

What is a readability score?
A readability score is a computer-calculated index which can tell you roughly what level of education someone will need to be able to read a piece of text easily.

There are several algorithms available for measuring scores, and these use factors like sentence length, syllable count, the percentage of multi-syllable words and so on to calculate their own readability score.

Does this only work with English?
Several readability algorithms use syllable counting to determine their scores. The current syllable counter used here will only work with English text, so scores for other languages may be inaccurate.

The Coleman-Liau and Automated Readability Indexes do not use syllable counting, so should produce a reasonably accurate score in most European languages.

Languages like Arabic or Chinese, which reference words in different ways, will not score accurately due to inaccurate letter counting and sentence analysis.

What algorithms do you use?
