Quickly check your SMS character count using our free length calculator. Determine the number of SMS credits that could be used and whether your message contains any unicode characters.
When it comes to determining the maximum length of an SMS message we need to take into account several factors. The standard message length is 160 characters but this can change depending on the types of GSM characters in your text message.
We've built this SMS Length Calculator so that you can quickly identify how many SMS credits you'll consume in a text message via our API. We automatically detect non-GSM characters and highlight to you how many messages you might use.
