Text Limiter is a free extension for the Meta Box plugin which allows you to limit the number of characters or words entered for text and textarea fields.
Using Text Limiter extension, you will have a similar input field like post content where the numbers of words entered and left are shown. It's very useful when you need to restrict the limit of the content entered by users to prevent unexpected result.
The numbers are updated in real-time. If users enter more than the specific words (or characters), the plugin automatically truncates the text to keep the length under the maximum value configured.
