Introduction
Character limits appear in SMS gateways, database columns, tweets, meta descriptions, and form fields. Counting “characters” is ambiguous: does a user mean code points, UTF-8 bytes, or grapheme clusters including emoji? This Character Counter surfaces multiple metrics at once—raw length, length without spaces, UTF-8 and UTF-16 byte sizes, lines, paragraphs, spaces, tabs, emoji, letters, digits, and special characters—so you can match the constraint that actually matters.
How the tool works
UTF-8 byte length uses TextEncoder. UTF-16 code units reflect JavaScript string length semantics used by many web APIs. Emoji detection uses Unicode property escapes where supported, with a safe fallback. Live updates are debounced for large pastes. Results can be copied or downloaded as text reports.
Use cases
Meta description tuning, SMS segmentation estimates, password field audits, CSV cell size checks, and game dialogue limits. Combine with Word Counter for narrative metrics and URL Encoder when length includes percent-encoded strings.
Benefits
Multi-metric clarity, private local analysis, RTL-friendly input, accessibility live regions, and consistent WebTools chrome with theme support.
Best practices
Work with the smallest representative sample when debugging edge cases, then scale to full documents. Prefer UTF-8 sources. When results feed production systems, re-validate outputs with unit tests in your repository. Clear sensitive drafts after use on shared devices.
Tips
Use keyboard shortcuts where available, paste large text in chunks if memory is constrained, and pair related WebTools (format → preview → export) for end-to-end workflows without leaving the browser.
Why byte counts matter
Not every system counts characters the same way. JavaScript strings use UTF-16 code units, while HTTP bodies, databases, and many APIs store UTF-8 bytes. A single emoji can be one visible glyph yet four UTF-8 bytes and two UTF-16 units. This Character Counter reports both so you can match the constraint of the system you are targeting—whether that is a VARCHAR column, an SMS segment estimate, a meta description soft limit, or a game localization field.
Additional tallies for spaces, tabs, lines, paragraphs, letters, digits, and special characters help diagnose messy paste jobs from PDFs or chat apps. Live updates keep feedback immediate without freezing the UI on large pastes thanks to debounced recalculation. Download a text report for QA tickets or copy stats into Slack during content reviews.
RTL languages and mixed-direction strings are editable with dir=auto so Arabic or Hebrew drafts remain readable. Always verify final packaging in the destination product; this tool is an accurate local assistant, not a substitute for end-to-end encoding tests in production pipelines.
Security note: never paste production secrets into any browser tool on a shared machine without clearing afterward. WebTools does not upload your text, but shoulder-surfing and browser history of form fields are still environmental risks you control.
Tip: when comparing results with desktop editors, confirm whether trailing newlines are included. Some editors count a final EOF newline as an extra character or line. This tool counts exactly what is present in the textarea so you stay in control of edge characters copied from other apps.
Educational teams can project the counter during workshops to show how emoji and accented letters affect byte budgets differently than ASCII-only English. That visual lesson sticks better than slides alone and requires no student accounts.

FAQ
Why do UTF-8 and UTF-16 differ?
Multi-byte characters encode differently; emoji often need 4 UTF-8 bytes and surrogate pairs in UTF-16.
Is text uploaded?
No.
What Is a Character Counter?
A character counter is a tool that counts how many characters are in a piece of text. Characters can include letters, numbers, spaces, punctuation marks, symbols, emojis, and line breaks.
How to Use the Character Counter
Type or paste your text into the text box above. The character count, word count, space count, letter count, sentence count, paragraph count, line count, unique word count, unique character count, emoji count, symbol count, number count, common platform character limit counts, and estimated page count update automatically as you type.
How to Check a Character Limit
Enter a number in the optional Set Character Limit box. The tool will show how many characters you have remaining or how many characters you are over the limit.
Common Platform Character Limits
On desktop, the counter also compares your current character count with common limits for X/Twitter, Text Message (SMS), Instagram captions, and LinkedIn posts. These boxes show your current count next to each platform limit, such as 142 / 280.
Characters With Spaces vs Without Spaces
Spaces usually count as characters when a platform, form, or application gives a character limit. The include-spaces checkbox is checked by default. Uncheck it if you want the main character count and remaining character calculation to ignore spaces.
