Plain and spaced cannot turn into boxes. Bold and italic can, when the font on the device has no glyph for those letters. The count uses Unicode characters, which is also how the post limit is defined, though the app’s own counter is the one that decides when you paste.
How to use
- Type the post, up to 280 characters.
- Press Style and read the four counts.
- Copy one row. Reset restores Hello.
Formula / how it works
The limit is the point of a separate page. A bold letter is still one character, so styling does not buy you a longer post. A space between every letter does cost characters: “Hello” is 5, and “H e l l o” is 9. The spaced count is there so you see the cost before you paste. The aesthetic font generator makes the wide look without the 280 figure. This page puts the figure on every row.
What each row is. Plain is the text unchanged. Spaced inserts a normal space between characters and keeps case. Bold and italic are the mathematical alphabets. They are not the app’s bold button, and the app does not offer one in the post composer. If a row shows a box, that glyph is missing. Copy the plain or spaced row. Both are the letters you can type on a keyboard.
URLs, mentions and tags. This page does not understand them. It will happily put spaces inside a link or a hashtag and break both. Style a display phrase, not the handle and not the URL. A mention has to stay contiguous or it stops being a mention.
What 280 does not include. The count is the row itself, not a thread, not the quote, not an attached image’s alt text. Images do not add to the 280. A link may be counted as a shortened length by the service and as its full length here. When the two disagree, trust the composer after you paste.
Length of the box. The field stops at 280 characters because a longer plain string is already over the limit before any spaces are added. There is nothing useful to style past that for a single post.
Threads and replies. A reply has the same 280-character ceiling as a top-level post. This page does not number a thread or split a paragraph into posts. If the spaced row crosses 280, shorten the words. Do not expect the service to hide the extra spaces. Quotes of someone else’s post are not included in the count you see here, and adding a quote in the app can change how many characters you have left. Paste, then look at the composer’s own number.
Case on the spaced row. Unlike the aesthetic page, spacing here keeps your capitals. “Hi” stays “H i”, with the H still capital. That matters for a name. Bold and italic also keep case, using the capital and small-letter forms of those alphabets. If only the capital shows as a box and the small letters do not, the font is missing one of the two forms. Fall back to spaced.
Worked examples
Five letters and the spaced cost
Inputs: Text: Hello
Leave the text as Hello and press Style. Plain is 5 of 280. Spaced is 9 of 280.
Result: Plain (5/280): Hello
Spaced (9/280): H e l l o
Bold (5/280): 𝐇𝐞𝐥𝐥𝐨
Italic (5/280): 𝐻𝑒𝑙𝑙𝑜
A post allows 280 characters. Bold and italic are Unicode letters; a box means the font lacks that glyph. The spaced row uses ordinary letters.
A two-letter word
Inputs: Text: Hi
Change the text to Hi and press Style. Plain is 2 of 280 and spaced is 3 of 280.
Result: Plain (2/280): Hi
Spaced (3/280): H i
Bold (2/280): 𝐇𝐢
Italic (2/280): 𝐻𝑖
A post allows 280 characters. Bold and italic are Unicode letters; a box means the font lacks that glyph. The spaced row uses ordinary letters.
Use cases
- Checking the spaced length before a short post.
- Choosing plain text when bold shows boxes.
- Comparing italic with bold on a slogan.
- Keeping a hashtag out of the styled region.
Tips & limitations
- Do not put spaces through a URL or a hashtag.
- Trust the app counter after you paste if it differs.
- Use plain or spaced when the bold row is boxes.
- A bold letter does not save you a character.
FAQ
Can I upload a font to a post?
No. The composer stores characters. Bold and italic here are other letters, not a typeface file.
Does bold let me write more than 280?
No. Each bold letter still counts as one character.
Why is the spaced line longer?
A space is a character. Five letters with gaps between them are nine characters.
What if I see boxes?
The font lacks that glyph. Copy the plain or spaced row. Those are ordinary letters.
Will a hashtag survive spacing?
No. A tag has to be one run of characters. Style the words around it, not the tag.
Is the post sent?
No. You copy a row yourself.
