Reading Time Calculator

How it works

• Paste the text you want to measure.
• The tool counts the words and estimates reading and speaking time.
• Adjust the words-per-minute speed to match a slower or faster audience.

Use cases

Where reading-speed numbers come from

The 200–250 words-per-minute figure for adult silent reading comes from decades of reading research, most recently consolidated in large meta-analyses of reading-rate studies. Speed varies with purpose: skimming runs 400+ wpm, careful technical reading drops to 50–100 wpm, and reading on a phone measures slightly slower than paper. The 130 wpm speaking rate this tool uses matches typical presentation pace — conversational speech is faster (150–160), audiobook narration slower and steadier.

That is why the tool separates reading time from speaking time: a 1,000-word article is a 5-minute read but nearly an 8-minute speech.

Using estimates for real deadlines

Speakers: a 20-minute conference slot at 130 wpm is roughly 2,600 words — write to 2,400 to leave room for pauses and slides. Publishers: displayed read time measurably affects whether visitors commit to an article, which is why Medium pioneered showing it. Teachers and meeting organizers: pre-reading assignments at 200 wpm mean a 3,000-word document costs each person 15 minutes — knowing that number keeps agendas honest.

Speaking time is not reading time divided by a constant

Silent reading runs at roughly 200 to 250 words per minute for an adult reading comfortable prose. Speaking is much slower, and the right figure depends on what kind of speaking it is. Conversational delivery sits around 150 words per minute. A presentation to a room, where you want to be followed rather than merely heard, runs closer to 130. Deliberately slow and clear delivery — a technical explanation, or an audience listening in a second language — is nearer 110. Audiobook narration is typically 150 to 160, and podcast conversation often runs faster at 160 to 170 because the informality carries it.

The larger error in most estimates is not the pace but the pauses. A delivered talk stops at the end of sentences, breathes between paragraphs, waits after a question, and pauses while a slide changes. None of that is in the word count, which is why a script that times at eight minutes reliably runs to ten in the room. The pause allowance option adds a realistic half-second at each sentence end and a second and a half between paragraphs.

For a fixed slot, work backwards from the time rather than forwards from the draft. A twenty-minute conference talk at presentation pace is roughly 2,600 words before pauses, and closer to 2,200 once you allow for them. Writing to that number from the start is far easier than cutting a finished script, and the per-paragraph view shows where you are at each point so you can find the halfway mark and the section to cut.
