A message that overflows its field gets truncated or rejected, and different channels enforce very different limits.
Message Length Checker lets you pick the limit for the channel you are writing for, or set your own, then shows whether the message fits so you can trim before sending.
How to use Message Length Checker
- Pick a preset such as SMS 160, push 120 or post 280.
- Paste your message and read whether it fits the chosen limit.
- Trim the wording until the message is within the limit.
Use cases
- Keeping a customer support reply inside a channel limit.
- Fitting a push notification into its preview length.
- Sizing a marketplace or listing message before you send it.
Good to know
Channels count length differently, and detailed SMS segmentation into 160 or 70 character parts belongs on the dedicated SMS counter. This tool checks a message against a chosen overall limit, with grapheme-aware counting so emoji count as one character.
Frequently asked questions
Which presets are available?
Common channel limits such as SMS 160, push 120 and post 280, plus the option to set a custom limit.
How is this different from an SMS counter?
This checks a message against an overall limit. For GSM-7 versus Unicode segmentation into 160 or 70 character parts, use the SMS character counter.
Do emoji count as one character here?
Yes. Counting is grapheme-aware, so an emoji counts as a single character against the limit.
