The LENGTH (or LEN) function returns the number of characters in a text string.
For example, you can use LENGTH to determine if a string is within the character limit for another system.
Syntax
LENGTH(Text to evaluate)
Arguments
| Argument | Data type | Description |
| Text to evaluate | Text | The text to evaluate the number of characters within. The LENGTH function returns the number of characters as a number. |
The LENGTH function returns a number.
Syntax example
LENGTH(Customer comments)
In this example, the LENGTH function returns the number of characters for each value of the text-formatted Customer comments line item.
Additional information
Behavior with spaces and blank values
When the Text to evaluate argument contains whitespace characters, each of these are counted as a single character by the LENGTH function.
If a value for the Text to evaluate argument has no characters, the LENGTH function returns a value of zero.
The LEN function
Instead of LENGTH, you can use LEN. The LEN function is functionally identical to the LENGTH function except for its name.
Constraints
For some unicode symbols outside the Basic Multilingual Plane the LENGTH function returns 2 for a single character. For example, text values that are encoded as a combination of two characters (a base character and accent), or emoji.

Within character limit for reports?
|
In this example, a module contains information about profit for each month. Time displays on columns, and line items on rows.
The text-formatted Profit Commentary line item contains manually entered text about the profit each month. The number-formatted Commentary Length line item uses the LENGTH function to return the number of characters in Profit Commentary as a number. The Boolean line item Within character limit for reports? then uses the result of Commentary Length and calculates if it's under 70.
