Character counter

Each character you see counts as one, so an emoji, a flag or an accented letter is one character, even when it takes several code units inside the computer. Spaces and line breaks count too; "no spaces" leaves out all whitespace.

X counts its own way: every link counts as 23 characters however long it is, because X shortens it, and every emoji and every Chinese, Japanese or Korean character counts as 2. The X meter follows those rules. It spots links that start with http or www and bare addresses on common endings like .com; X recognizes a few more. Paid X accounts can post longer texts, so 280 is the limit for standard accounts.

A text uses the GSM-7 alphabet when it can, which fits 160 characters in one message. A single character outside it, such as an emoji, a curly quote or many accented letters, switches the whole message to UCS-2, which fits only 70. Longer texts are split into parts of 153 (GSM-7) or 67 (UCS-2) characters that phones join back together. The SMS meter names the character that caused the switch, and a few symbols like € [ ] { } count as 2 in GSM-7.

Google says there is no limit on how long a meta description can be, and it cuts snippets to fit the screen. Keeping to about 155 to 160 characters is a common rule of thumb for showing in full on a computer, so the meter uses 160 as a guide, not a rule. Google may also write its own snippet from your page instead.
