Solution 1Recommended

Update macOS and Microsoft Word

Outdated software is the most common reason readability formulas fail to calculate. Updating your operating system and Word application resolves these calculation glitches.

Readability statistics rely on accurate word, syllable, and sentence counts. Bugs in older versions of Word or macOS can disrupt these counts, resulting in a zero score. Updating to the latest software version patches these known bugs.

1
Update macOS

Click the Apple menu in the top-left corner of your screen, select 'System Settings' (or 'System Preferences'), and navigate to 'General' > 'Software Update'. Install any available updates.

2
Check for Word Updates

Open Microsoft Word. In the top menu bar, click on 'Help' and select 'Check for Updates'.

3
Update Microsoft AutoUpdate (if needed)

If the updater says no updates are available but your Word version is outdated (e.g., older than 16.65 on Ventura), update the Microsoft AutoUpdate tool itself first, then check for Word updates again.

Update macOS and Microsoft Word
Restart Required: You may need to restart your Mac after installing operating system and Microsoft Office updates for the changes to fully take effect.

Frequently Asked Questions

Why is the Flesch Reading Ease score showing exactly 0.0 in Word?

A score of exactly 0.0 usually indicates a software glitch where the proofing tool fails to accurately count syllables or sentences, which are required for the Flesch readability formula. Updating Word and macOS typically resolves this bug.

Where can I find the readability statistics in Word for Mac?

After enabling 'Show readability statistics' in Word > Preferences > Spelling & Grammar, you need to run a complete spelling and grammar check on your document. A dialog box displaying the word count and readability scores will automatically appear once the check is finished.

Will fixing the readability statistics alter my document's formatting?

No, updating your software or changing the proofing preferences to display readability statistics does not change your document's layout, text, or formatting. It only affects how Word calculates and reports writing metrics.

What if my statistics still show zero after updating Word and my Mac?

If updates do not work, copy your text and paste it into a brand-new Word document to see if the issue is specific to the original file. If the new document also fails, you may need to completely uninstall and reinstall Microsoft Office.
