Word Count, Character Count, and Readability: How to Check Your Writing
Use word count to check a length requirement, character count to check a text limit, and readability scores to inspect sentence length and word complexity. Before editing, confirm what your destination measures and which parts of the draft it includes.
Open the GlyphFlow workspace with your draft and the destination’s instructions.
Choose the measurement your task requires
| Your task | Measurement to check | Detail to confirm |
|---|---|---|
| Meet an assignment or editorial word limit | Word count | Whether the instructions include headings, references, or captions |
| Fit text into a submission field | Character count | Whether the field includes spaces and how it counts symbols |
| Submit text under a limit that excludes spaces | Character count without spaces | Whether the destination also excludes tabs and line breaks |
| Review the wording of a prose passage | Flesch Reading Ease, alongside the text | Which passage you measured and how the tool estimated its counts |
For a 500-word brief, use the word total. For a 500-character field, check the character total.
Check word count against the brief
Paste this sentence into GlyphFlow without a surrounding blank line:
Send the draft by Friday.Under GlyphFlow’s current counting rules, you get 5 words, 25 characters, and 21 characters without spaces. You have four spaces between the words; the full stop contributes one character.
GlyphFlow identifies words through a pattern that matches English letters, digits, apostrophes, and hyphens at word boundaries. It counts 2026 as one word and well-written as one word. Another counter can apply different rules to numbers or hyphenated terms.
Use an assignment’s required submission tool for the final count. With a client, agree on the counting method if your totals differ. For text in other languages, check that your counter supports the language’s word boundaries and writing system.
For web content, write enough to answer the reader’s question within your brief. Google’s people-first content guidance states that Google has no preferred word count.
Check characters, spaces, and symbols
GlyphFlow includes spaces and punctuation in its main character count. Its “no spaces” total removes whitespace, including tabs and line breaks, through JavaScript’s \s pattern. The ECMAScript specification defines that pattern’s whitespace and line-terminator categories.
GlyphFlow measures character totals in UTF-16 code units, the units JavaScript uses for string length. The ECMAScript String specification explains this representation. You can see one symbol and get a count greater than one: 😀 contributes two units.
Unicode uses grapheme clusters to approximate the characters you perceive. You can combine several underlying components into one cluster, as the Unicode text-segmentation standard describes. Check the destination’s editor before submitting text with emoji or combining accents near a limit.
For worked examples of spaces, line breaks, and emoji sequences, read Character Count With and Without Spaces.
Check the complete platform draft
LinkedIn’s official documentation sets a 3,000-character limit for a feed post, checked October 6, 2026. Include the URLs, hashtags, punctuation, and line breaks you plan to paste when you check the draft in GlyphFlow.
LinkedIn’s Help page does not specify its Unicode counting unit. Confirm the finished post in LinkedIn’s editor, including any edits you make there.
Read the Flesch score alongside your text
Rudolf Flesch introduced Reading Ease in his 1948 paper “A New Readability Yardstick”. To calculate it from total counts, use:
206.835
− 1.015 × (words ÷ sentences)
− 84.6 × (syllables ÷ words)With the other inputs unchanged, you get a higher result by reducing words per sentence or syllables per word. In GlyphFlow, you see a whole-number score from 0–100. The calculation uses estimated syllables from English vowel patterns; GlyphFlow rounds and clamps the result for display.
Choose a passage for review. Look for a sentence that packs several instructions together or a term your audience may not recognize. Split the instructions or explain the term, then read your revision to check that you kept its meaning.
The US Agency for Healthcare Research and Quality cautions against using readability formulas to judge a report’s suitability. A score does not establish whether readers understand the content, recognize the vocabulary, or can use the information.
In “Varieties of Plain Language”, Allen Riddell and Yohei Igarashi analyze plain-language writing samples. They describe separate sentence and vocabulary measurements as complements to usability testing and document design. Check how you organize and explain the content as part of your review.
Compare tools using the same passage
Give each checker the same text, including the same headings and lists. Confirm that you are comparing Flesch Reading Ease with Flesch Reading Ease, then inspect the word and sentence totals.
GlyphFlow splits sentences at periods, exclamation marks, and question marks. Paste Dr. Lee sent the note. and you get two sentences because of the period after Dr. A tool that recognizes the abbreviation could count one, changing the words-per-sentence input.
You can also get different displayed scores from syllable estimates, rounding, or limits on the displayed range. AHRQ’s guidance discusses measurement problems from punctuation and text outside full sentences. Inspect your sample before rewriting it to reconcile two scores.
Use a repeatable check before submitting
- Read the requirement. Identify the measurement, limit, and parts of the document you must include.
- Check the complete text. Paste that selection into GlyphFlow and inspect the relevant count.
- Revise with the reader’s task in view. Remove repetition to meet a limit. Explain unfamiliar terms and separate instructions where the wording needs work.
- Check meaning with a reader. Ask someone from your intended audience to explain the main point and what they would do next. This is a suggested exercise; the CDC recommends audience testing when developing communication materials.
- Confirm in the destination. Recheck the text after pasting and after any final edits.
After your final edits, check the count again in GlyphFlow, then confirm it in the submission tool or platform editor.
