Reading Time Calculator: limits and things worth knowing

• Silent reading averages around 200-250 words per minute for adults on general prose. Technical material is substantially slower, and the figure varies widely between individuals.
• Speaking is much slower: 130-150 words per minute is a comfortable presentation pace, so a 10-minute talk is about 1,300-1,500 words.
• Word count alone ignores images, code blocks, tables and formulas, all of which take time to process and none of which contains many words.
• Displayed reading times are estimates and are known to influence whether people start reading at all — which is the actual reason to show one.

Is it private and secure?

Your privacy is built in. Reading Time Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
