Where limits matter

  • SMS messages and notifications.
  • Search result titles and descriptions.
  • Social media posts and bios.
  • Ad headlines and product titles.

How to check

  • Open Character Counter and paste your text.
  • See the count with and without spaces.
  • Compare it with the limit shown for the platforms.

Spaces and emojis

Some platforms count spaces, and some count emojis as more than one character. If you are close to a limit, test the text on the platform itself before you rely on the number.

Writing tight

Cut filler words such as very, really and just. Use numerals instead of spelled-out numbers, and replace long phrases with short ones.

Frequently asked questions
