Average word length calculator

Average word length is the mean number of characters in each word of a passage after punctuation is ignored.

Writers, editors, teachers, and product teams use that single number to compare vocabulary density, check readability targets, and spot drafts that lean on unusually long technical terms or very short filler words. This average word length calculator accepts plain text, splits it into whitespace-separated tokens, strips punctuation so commas, periods, and quotes never inflate or split counts, and returns the arithmetic mean of the remaining letter and digit characters per word. Empty paste, pure whitespace, and strings that contain only symbols fail with a clear validation error instead of a silent zero. The free browser form and the API share one pure deterministic function, so classroom checks, CMS gates, and automation scripts always agree on the same string.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

For developers — API access

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

API endpoint

POSThttps://api.kit.forhosting.com/text/average-word-length

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

curl -X POST https://api.kit.forhosting.com/text/average-word-length \
  -H "Authorization: Bearer $KIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello, world! Average word length is useful."}'

const res = await fetch("https://api.kit.forhosting.com/text/average-word-length", {

Example request

{
  "text": "Hello, world! Average word length is useful."
}

Example response

{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "text.average_word_length",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.
