## Introduction

Would you like to limit characters for the **Rich Text** form field? The **Single Line Text** and **Paragraph** form fields, have a built-in feature that allows you to limit the characters or words for this field. To learn more about this, [please take a look at this helpful guide](https://wpforms.com/docs/how-to-limit-words-or-characters-in-a-form-field/ "Limiting Words or Characters in a Field").

However, if you wanted to limit the characters for the **Rich Text** form field, you can easily use a small snippet and in this tutorial, we’re going to show you how.

## Creating the form

Begin by creating a new form and adding your fields, including at least one **Rich Text** form field.

If you need any assistance in creating your form, [please see this documentation](https://wpforms.com/docs/creating-first-form/ "Creating Your First Form").

## Adding the snippet

Now it’s time to add the snippet to your site. For any assistance on how and where to add snippets to your site, [please see this tutorial](https://wpforms.com/developers/how-to-add-custom-php-or-javascript-for-wpforms/ "How to Add Custom PHP or JavaScript for WPForms").

```

/**
* Add Rich Text field validation.
*
* @link https://wpforms.com/developers/how-to-limit-characters-for-the-rich-text-field/
*/
 
function wpf_dev_validate_richtext( $field_id, $field_submit, $form_data ) {
 
    // Optional, you can limit to specific forms. Below, we restrict output to form #3382.
    if ( absint( $form_data[ 'id' ] ) !== 3382 ) {
        return $field_id;
    }

	// Set the maximum character limit here
    $max_characters = 150;

    // Check for character limit
    $char_count = mb_strlen( $field_submit, 'UTF-8' );
    if ( $char_count > $max_characters ) {
        $error_message = sprintf(
            esc_html__( 'Character limit exceeded. The maximum number of characters allowed is %d.', 'wpforms' ),
            $max_characters
        );
        wpforms()->process->errors[ $form_data['id'] ][ $field_id ] = $error_message;
    }

}
add_action( 'wpforms_process_validate_richtext', 'wpf_dev_validate_richtext', 10, 3 );
```

This snippet will **only** look at the form ID **3382**, you’ll need to update this ID number to match your own form ID. If you’re not sure where to find your form ID number, [please review this tutorial](https://wpforms.com/developers/how-to-locate-form-id-and-field-id/ "How to Locate Form ID and Field ID").

The next part of the snippet is looking at the **$max\_characters** variable which is set to have a limit of **150** characters. As the snippet is processed, it will look and count the characters (UTF-8 format) in this field and if the number of characters exceeds the **150** limit, when the form submits, it will display an error.
