Character Counter

Count characters with and without whitespace and inspect UTF-8 byte size. Understand why emoji counts and platform-specific limits can differ.

Inspect the size of a message, caption or plain-text value while you edit it. Total Characters uses JavaScript string length, Without Spaces removes whitespace, and Byte Size measures the UTF-8 representation. These numbers answer different questions and may not match a platform's own quota.

About Character Counter

Inspect the size of a message, caption or plain-text value while you edit it. Total Characters uses JavaScript string length, Without Spaces removes whitespace, and Byte Size measures the UTF-8 representation. These numbers answer different questions and may not match a platform's own quota.

Two character totals

Displays counts with and without whitespace.

Encoded byte count

Measures the text as UTF-8 bytes using a Blob.

Live updates

The counters respond to changes without a separate counting action.

How to use Character Counter

  1. 1

    Enter your message

    Paste or type the exact text, including any line breaks that will be submitted.

  2. 2

    Compare the measures

    Use Total Characters for UTF-16 length, Without Spaces for length after whitespace removal, and Byte Size for encoded bytes.

  3. 3

    Check the target field

    Paste the final text into the intended platform and use its own validation for a strict limit.

Formats and practical limits

Input: plain text. Output: UTF-16 character totals, a basic 280-unit estimate and UTF-8 byte size.

  • Visible symbols, UTF-16 units and UTF-8 bytes are different measurements.
  • This does not calculate SMS billing segments or enforce any social platform's current rules.

Practical example

A simple emoji such as 😀 occupies two UTF-16 units and four UTF-8 bytes. Do not interpret either value as two or four visible symbols.

Frequently Asked Questions

3 answers
Why can one emoji count as more than one?

JavaScript string length counts UTF-16 code units. Many emoji use two units, and combined emoji can use several. This is not a grapheme-cluster count.

Does Without Spaces remove newlines?

Yes. The implementation removes JavaScript whitespace matches, including ordinary spaces, tabs and line breaks.

Is the Tweets estimate a platform guarantee?

No. It uses a simple 280-unit division. Real platform rules can weight URLs or characters differently; confirm the limit there.
