# String: Length between

> Checks that a string's length is between a minimum and maximum value.

Checks that a string's length is between a minimum and maximum value. A value passes when its number of characters falls within the range you set, counting both ends of the range as valid. Use this to confirm that a value is neither too short nor too long, for example a password that must be 6 to 12 characters or a description that must stay within a size limit.

This documentation describes: [Schema](/schemas/condition/string-length-between)

## Fields

<FormField property="min" label="Minimum">
  The smallest number of characters the value may have. A value shorter than this does not match.
</FormField>

<FormField property="max" label="Maximum">
  The largest number of characters the value may have. A value longer than this does not match. Leave it empty to set only a minimum, with no upper limit.
</FormField>

## Sample data

| Field   | Value |
| ------- | ----- |
| Minimum | `6`   |
| Maximum | `12`  |

The condition checks each value and answers yes or no:

| Example value                   | Matches?           |
| ------------------------------- | ------------------ |
| `secret`                        | Yes (6 characters) |
| `pw`                            | No (too short)     |
| `this-password-is-way-too-long` | No (too long)      |
