Word Count and Length

Length is a strategic choice. Too short and your message lacks substance. Too long and readers drop off. TextScore measures your word count and maps it against platform-specific sweet spots so you can size your content for maximum impact.

Every platform imposes hard limits. Going over means your content gets truncated or rejected. These are the current limits as of 2026:

• X (Twitter): 280 characters (free accounts) | 25,000 characters (premium)
• Facebook: 63,206 characters for posts
• Instagram: 2,200 characters for captions
• LinkedIn: 3,000 characters for posts | 125,000 characters for articles
• Discord: 2,000 characters per message
• Medium: No hard limit, but articles over 7 minutes read time see declining completion rates

X (Twitter)

Sweet spot: 70-100 characters. Tweets in this range get 17% more engagement than longer ones. The 280-character limit is a ceiling, not a target. Shorter tweets get more retweets. Threads perform well when each post is self-contained and punchy.

LinkedIn

Sweet spot: 1,200-1,600 characters for posts. Long enough to share a real insight. Short enough to read without clicking "see more." For articles, 1,000-2,000 words performs best. Posts that require expanding tend to lose 40-60% of potential readers at the fold.

Medium

Sweet spot: 1,400-1,750 words (7-minute read). Medium's own data shows that 7-minute articles get the most total reading time. Going past 10 minutes drops completion rates significantly. If your article is longer, consider splitting it into a series.

Discord

Sweet spot: Under 200 characters for conversation. Under 1,000 characters for announcements. Discord is chat, not publishing. Long messages get skipped. If you need more space, use a thread or link to an external document.

Facebook

Sweet spot: 40-80 characters for maximum engagement. Posts with under 80 characters get 66% more engagement than longer posts. Save the long-form content for blog links. Your Facebook post should be the hook, not the article.

The Attention Curve

Reader attention drops predictably. The first sentence gets read by nearly everyone. By the third paragraph, you have lost 30-50% of readers. By the tenth paragraph, only the most invested remain. Every word you add needs to earn its place.

Platform Algorithm Effects

• X: Shorter tweets get more impressions per character. The algorithm favors posts that generate quick engagement.
• Medium: Read ratio (percentage of viewers who finish) affects distribution. A shorter article with a high read ratio outperforms a longer one with a low ratio.
• LinkedIn: Dwell time matters. Content that keeps readers on the page (not too short, not too long) gets boosted.
• Facebook: The algorithm measures whether users stop scrolling. Short, punchy posts create more stops than walls of text.

TextScore evaluates your word count relative to the platform you selected. The same word count might score Good for Medium and Poor for X.

• Good (Green): Your content length falls within the optimal range for your chosen platform.
• Fair (Yellow): Slightly outside the optimal range. Your content may still perform but could benefit from trimming or expanding.
• Poor (Red): Well outside the optimal range. Either too short to provide value or too long for the platform's audience behavior. Adjust accordingly.
