The character limit for a single text message in the Meta WhatsApp Business API is 4,096 characters. This limit applies to both regular text messages and message templates. Although there is a higher overall limit for the total length of a message (including text, spaces, and special characters) of 65,536 characters, it is recommended to stay within the 4,096 limit for optimal performance and better user experience.
Below is the breakdown of character limits in the context of WhatsApp Business:
Individual text messages: 4,096 characters
Header: 60 characters, including the parameter name (e.g. {{{1}})
Body: 1,024 characters, including dynamic values
Template foot (Footer): 60 characters
Interactive list rows: 24 characters for the title and 72 for description
Interactive response buttons: 20 characters for button label
It is important to note that exceeding the 4,096 character limit in a single message, or header/foot limits in templates, can cause problems with delivery or rejection of the message, depending on the Meta documentation.
We invite you to review the detailed summary for the creation of META templates as good practices.
