The 7 Text Metrics Every Writer Should Track (And Why Word Count Is Just the Beginning)
Most writers obsess over word count. But reading time, keyword density, reading level, sentence length, and syllable count tell you far more about whether your content will actually work.
Ask any writer how long their article is, and they’ll give you a word count. “It’s about 2,000 words.” As if that single number tells you everything you need to know.
It doesn’t.
A 2,000-word article written entirely in 40-word sentences with academic jargon is a completely different beast from a 2,000-word article written in punchy 12-word sentences with conversational language. Same word count. Vastly different reading experiences. Vastly different performance.
At TextWordCount, we track 20+ metrics on every keystroke. But you don’t need all of them. Here are the 7 that actually matter — and what to do with each one.
---
## 1. Word Count (But Not How You Think)
Yes, word count matters. But not as an absolute number — as a benchmark against intent.
A product description should be 100-300 words. A blog post targeting Google should be 1,500-2,500 words. A LinkedIn post maxes out at about 700 words before engagement drops. A tweet thread works best at 200-250 words per thread.
The mistake most writers make: they write to a word count instead of writing to completion and then checking. Write until the idea is fully expressed. Then check the count. If it’s 800 words and the target format wants 1,500, you have a thin piece that needs more depth — not more filler.
**What to track:** Word count relative to your target format, not as an isolated number.
---
## 2. Reading Time
This is the metric your audience actually cares about. Nobody thinks “I want to read a 2,000-word article.” They think “Do I have 8 minutes right now?”
The standard calculation uses 238 words per minute for average adult reading speed (based on research by Brysbaert, 2019). But context matters:
- Technical content: ~200 wpm (readers slow down for complexity)
- Casual blog posts: ~250 wpm (familiar territory, faster scanning)
- Academic papers: ~150 wpm (dense, requires re-reading)
Medium displays reading time prominently on every article because they found it directly impacts click-through rates. Articles showing “5 min read” get more opens than articles with no time indicator — readers want to know the commitment before they start.
**What to track:** Keep blog posts under 8 minutes (about 1,900 words). For newsletters, under 4 minutes (about 950 words). For social content, under 1 minute.
---
## 3. Reading Level
Most online content should target a 7th-8th grade reading level. Not because your audience is unintelligent — because they’re reading on phones, scanning between meetings, and processing your content alongside 50 other tabs.
The Flesch-Kincaid Grade Level formula calculates this from sentence length and syllable count:
Grade Level = 0.39 × (words/sentences) + 11.8 × (syllables/words) - 15.59
TextWordCount calculates this in real time. If your reading level shows “College” when you’re writing a blog post for small business owners, your sentences are too long, your words are too complex, or both.
The Flesch Reading Ease score (0-100) is the inverse: higher is easier. Target 60-70 for general web content, 50-60 for professional audiences, 30-50 for academic writing.
**What to track:** Aim for 7th-8th grade for blogs and marketing. 10th-12th for B2B professional content. Leave “College” level for actual academic writing.

## 4. Average Sentence Length
This is the single best predictor of readability — more reliable than grade level or reading ease alone.
Research from the American Press Institute found:
- 8 words or fewer: 100% comprehension
- 14 words: 90% comprehension
- 43 words: less than 10% comprehension
The sweet spot for online content is 15-20 words per sentence. But variety matters even more than average. A paragraph of five 17-word sentences reads like a metronome. Mix short punches (5-8 words) with medium sentences (15-20) and occasional longer ones (25-30) for natural rhythm.
TextWordCount shows you average sentence length, longest sentence, and shortest sentence. If your average is above 25, you need to break things up. If your longest sentence is above 40, split it.
**What to track:** Average between 15-20. Longest sentence under 30. Mix of lengths for rhythm.
---
## 5. Keyword Density
This one’s for SEO writers, but even non-SEO writers benefit from it.
Keyword density = (keyword appearances / total words) × 100
The old SEO advice was to hit 2-3% density for your target keyword. Modern SEO is more nuanced — Google’s algorithms detect keyword stuffing and reward natural language. But knowing your keyword density still matters for two reasons:
First, if your primary keyword appears at 0.1%, you’re probably not covering the topic thoroughly enough. If it appears at 5%, you’re stuffing.
Second, keyword density reveals your content’s actual topic. If you think you wrote an article about “email marketing” but your top keyword is “social media,” your article wandered off-topic.
TextWordCount shows your top 10 keywords with frequency count and percentage. This surfaces topic drift, stuffing, and gaps in under a second.
**What to track:** Primary keyword at 1-2%. Top 10 keywords should align with your intended topic. No single keyword above 3%.
---
## 6. Syllable Count & Complexity
Syllable count feeds into reading level, but it’s worth tracking independently because it reveals word complexity.
Average syllables per word:
- Conversational writing: 1.2-1.4
- Professional writing: 1.5-1.7
- Academic writing: 1.8-2.2
If your average exceeds 1.7 for blog content, you’re using too many multi-syllable words. This doesn’t mean dumbing down your ideas — it means expressing them in simpler language.
“Utilize” (4 syllables) → “Use” (1 syllable). Same meaning. “Approximately” (5) → “About” (2). “Demonstrate” (3) → “Show” (1). “Methodology” (5) → “Method” (2).
Every unnecessary syllable adds friction. Over 2,000 words, that friction compounds.
**What to track:** Keep average syllables per word under 1.5 for web content. Flag any word over 4 syllables and ask if a simpler alternative exists.
---
## 7. Speaking Time
If your content will ever be read aloud — podcasts, video scripts, presentations, speeches, webinars — speaking time is the metric that matters, not reading time.
The average speaking pace is 183 words per minute (slower than reading’s 238 wpm). But effective presentation pace varies:
- Conversational podcast: 150-170 wpm
- Formal presentation: 120-140 wpm
- Energetic YouTube video: 170-200 wpm
A 2,000-word script takes about 11 minutes to speak. If your YouTube video targets 8 minutes, you need ~1,470 words. If your podcast segment targets 20 minutes, you need ~3,660 words.
TextWordCount calculates speaking time alongside reading time so you can calibrate for either format.
**What to track:** Match speaking time to your format’s target duration. Subtract 10-15% for pauses, breathing, and natural delivery variation.

## Putting It All Together
Here’s a quick reference card for different content formats:
| Format | Words | Reading Time | Grade Level | Avg Sentence | Keyword Density |

| Product Page | 300-800 | 1-3 min | 6th-7th | 10-15 | 1-2% |
| Academic Paper | 3,000-8,000 | 15-40 min | 12th+ | 20-30 | 0.5-1% |
| YouTube Script (10min) | 1,500-1,800 | N/A | 6th-8th | 10-15 | N/A |
| Podcast Script (20min) | 3,000-3,500 | N/A | 7th-9th | 15-20 | N/A |
