Word Counts and Reading Time
Two programs will happily give you two different word counts for the same document, and neither is broken. They are answering slightly different questions, and knowing which one you need matters when a limit is enforced.
In short
- A "word" has no single definition — hyphens, numbers and URLs are treated differently.
- Character limits are usually enforced with spaces included; check before trimming.
- Average silent reading speed for adults is around 200–260 words per minute.
- Reading speed varies far more by material and purpose than by reader.
Why two tools disagree
The naive definition — a run of characters separated by whitespace — is what most counters use, and it is where the disagreements begin. The edge cases are common enough to shift a count by several percent.
| Text | Split on whitespace | Often counted as | Why |
|---|---|---|---|
| state-of-the-art | 1 | 1 or 4 | Hyphens may or may not split |
| https://example.com/a/b | 1 | 1 or 4 | Punctuation may split |
| 1,250 | 1 | 1 | Usually one word |
| e.g. | 1 | 1 or 2 | Full stops may split |
| don’t | 1 | 1 | Apostrophes rarely split |
| — | 1 | 0 or 1 | Some counters exclude bare punctuation |
For ordinary prose the differences are small. For technical writing full of hyphenated terms, code and URLs, two counters can differ by 5% or more — which matters when a limit is a hard cut-off.
Character limits and the space question
Where a platform enforces a character limit, it almost always counts spaces. A 160-character SMS limit means 160 including every space, and a meta description guideline of 160 characters works the same way.
This is why counters report both figures. "Characters excluding spaces" is useful for typesetting and for estimating page counts; "characters including spaces" is the number that decides whether your text fits.
Two further traps. Some systems count a character as a byte, so an accented letter or an emoji consumes more than one — an emoji can cost four. And some count what the user sees rather than what is stored, so a flag emoji built from two code points may count as one, two or four depending on the platform. When a limit really matters, test with the actual system rather than trusting a generic counter.
What reading speed actually is
Silent reading of ordinary prose by adults centres on roughly 200–260 words per minute, and most published estimates for comprehension-checked reading of general text fall in that band. Reading aloud is markedly slower, around 150 wpm, which is why audiobook and presentation timings use a different figure.
The variation within one reader is larger than the variation between readers. The same person might move through a familiar news article at 300 wpm, a contract at 100, and a dense technical paper at 50 — reading each one properly. Speed is a property of the material and the purpose at least as much as of the person.
| Material | Typical pace | 1,000 words takes |
|---|---|---|
| Reading aloud | 150 wpm | about 6:40 |
| Careful study or technical text | 100–150 wpm | 7–10 minutes |
| General prose, comprehension checked | 200–260 wpm | 4–5 minutes |
| Familiar or light material | 300 wpm | about 3:20 |
| Skimming for a specific fact | 400+ wpm | under 2:30 |
What the estimate on an article is for
The "5 min read" label is not a prediction about you. It is a rough length signal that helps a reader decide whether to start now or save it, and it works because relative lengths are more informative than absolute ones — a 12-minute piece is clearly a bigger commitment than a 3-minute one, whatever your personal speed.
Most publishers compute it as words ÷ 200 or ÷ 250 and round up. Some add time for images, on the reasoning that a reader stops to look. None of them account for how hard the material is, which is the largest factor of all, so treat the number as a size label rather than a schedule.
Where speed reading claims fall down
Claims of many hundreds or thousands of words per minute with full comprehension do not survive testing. The physical constraint is that reading requires the eye to fixate on text, and there is a floor on how briefly a fixation can land and still deliver usable information.
What such techniques reliably produce is skimming — genuinely useful for finding a specific fact or deciding whether something is worth reading properly, but a different activity from reading. The consistent finding when comprehension is measured is a trade-off: past a certain pace, speed rises and understanding falls. Nothing wrong with skimming, as long as you know that is what you are doing.
Practical lengths
Some numbers that come up repeatedly when writing to a limit:
- Page title for search results: around 60 characters before truncation.
- Meta description: 110–160 characters is the usual working range.
- SMS: 160 characters in the basic encoding, 70 if any character forces Unicode.
- A double-spaced A4 page in 12pt: roughly 250 words.
- A three-minute talk at a comfortable speaking pace: roughly 450 words.
Frequently Asked Questions
Why do two tools give different word counts?
Because "word" has no single definition. Counters differ on whether hyphenated compounds, URLs, abbreviations with full stops and bare punctuation count as one item or several. For plain prose the gap is small; for technical text full of hyphens and links it can exceed 5%.
Do character limits include spaces?
Almost always yes. A 160-character SMS limit and a 160-character meta description guideline both count spaces. The "excluding spaces" figure is useful for typesetting estimates but is not the number that decides whether your text fits.
What is the average reading speed?
Around 200–260 words per minute for silent reading of general prose by adults, with comprehension checked. Reading aloud is slower, about 150 wpm. Dense technical material can drop to 50–100 wpm without the reader being slow.
How is the "5 min read" label calculated?
Usually words divided by 200 or 250, rounded up, sometimes with a few seconds added per image. It ignores difficulty entirely, so treat it as a relative size label rather than a prediction — a 12-minute piece is a bigger commitment than a 3-minute one, whatever your own pace.
Can people really read thousands of words per minute?
Not with full comprehension. Eyes must fixate on text and there is a floor on how brief a useful fixation can be. What these techniques produce is skimming, which is genuinely useful for locating a fact or triaging material, but measured comprehension falls as pace rises past a certain point.
