Flesch Readability works for other languages?

  • I’m experiencing very low Flesch scores (even negative) on my italian content although it’s tweaked with short sentences etc.

    So i’m wondering, does this test work for other languages too?

  • Hello,

    Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

    It seems like the score is less actually. Please check here:

    Since the Flesch test does not depend on the language (mostly) so writing in Italian shouldn’t hamper the score.

    Can you please check with some other article?

    Looking forward to helping you.

    It does depend on language. For Spanish the Flesch-Fernández Huerta formula is used:

    206.84 – (0.60 x P) – (1.02 x F)

    Where P is the number of syllables per 100 words and F the number of sentences per 100 words. If a text reaches a score between 90-100 it means that it is very easy to understand (suitable for 4th graders) and between 0-30 very difficult (typical of a university level).

    I have tested this using this tool https://legible.es/ and Yoast SEO.
    Most of my posts are 80+ with Yoast and the tool linked above. Rankmath brings that score down to 20 / 30.

    Also, the Flesch-Kincaid formula is available for German, Spanish, Italian and others:

    For Italian also the Indice Gunning Fog:

    Hi Sergio,

    Thanks for the follow up.

    I have notified our developers about this and we will be looking further into this and get back to you in a short while.

    We appreciate your patience.

    Hi guys, hi Michael. It would be great to have the Flesch Test working in other languages than English. I need it for some Italian websites. (Yast do it pretty well ;-))
    Anyway, the plugin is excellent.
    Let me know if you have any news on that.

    Hey Emanuele,

    Thank you 🙂

    We are working on that.

    Would really appreciate your patience.
