Meta Description 155 Char Limit Checker
Explicit illustrative 155-codepoint metadata budget; not a search-engine limit or snippet-display guarantee.
Description
Meta Description 155 Char Limit Checker: return unicode codepoint count, exceeds illustrative155, search snippet guaranteed.
A meta description can be counted as text independently of how a search engine displays a snippet. A chosen length target is an editorial convention.
This tool returns unicode codepoint count, exceeds illustrative155, search snippet guaranteed. Use the stated units and model convention when interpreting these fields.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Count Unicode code points and flag a count strictly greater than 155.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| descriptionText | Description text. | Text |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.unicodeCodepointCount | Unicode codepoint count; use the stated units and sign convention. |
| result.exceedsIllustrative155 | Exceeds illustrative155 flag under the exact conditions described above. |
| result.searchSnippetGuaranteed | Always false; the character count cannot guarantee a search-result snippet. |

"searchSnippetGuaranteed": false

}
}Limitations and assumptions
- Combining sequences can occupy more than one code point. searchSnippetGuaranteed stays false.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
