Character Counter: Count Characters With or Without Spaces (Plus Social Limits)
You search for a character counter when a platform, form, or editor rejects your text with a vague error like 'too long' or 'invalid characters'. The goal is simple: know your exact length before you hit publish, submit, or schedule.

Quick answer
A character counter counts the exact length of your text. For most use cases, track these three numbers:
- Characters (with spaces): best for social posts, forms, and most UI fields.
- Characters (no spaces): useful when a system explicitly says it ignores spaces (rare, but it happens).
- Words: useful for essays, briefs, and word-based requirements.
If you are close to a limit, keep a small safety margin. Platforms can count emojis, line breaks, and some Unicode characters in surprising ways.
What counts as a character?
In plain language, a character is anything you can type: letters, numbers, punctuation, and symbols. Depending on the tool and platform, these often count too:
- Spaces between words
- Line breaks (pressing Enter)
- Emojis and symbols
- Invisible formatting copied from PDFs, slides, or rich text
Most character counters show both with-spaces and without-spaces because some workflows care about one more than the other.
Character count vs word count vs bytes
A word count splits on spaces (roughly). A character count counts every character. A byte count is deeper technical plumbing (encoding) and matters for APIs and databases, not most writing. If you are writing for people or platforms, start with characters and words.
How to count characters without any online tool
You can often stay offline and still get accurate counts:
- Google Docs: Tools > Word count (it shows characters with and without spaces).
- Microsoft Word: Review > Word Count (it shows characters with and without spaces).
- Excel or Google Sheets: use LEN(text) to count characters in a cell.
If you are copying text from a website, paste as plain text first to avoid hidden formatting.
Limits change, but you can still work fast
Limits can change, so treat numbers as a starting point and check the platform help center for the latest when it really matters.
| Where you are writing | Typical character limit | What to watch |
|---|---|---|
| X post | 280 typical; long posts up to 25,000 on some accounts | Some characters and URLs can count differently than you expect |
| LinkedIn post | 3,000 | Line breaks and emojis count, so keep a buffer |
| Instagram caption | 2,200 | Captions often truncate in-feed, so put the hook first |
| TikTok caption | 2,200 for many business/API postings; native limits can differ | If you schedule via a third party, test the same text natively |
| YouTube title | 100 | Search and mobile can truncate earlier, so front-load keywords |
| YouTube description | 5,000 | Links and attribution blocks can push you over fast |
| Instagram bio | 150 | Use clear keywords and remove invisible whitespace |

A simple workflow that avoids last-minute trimming
- Write the message once, in plain text.
- Check characters with spaces, characters without spaces, and words.
- Trim from the end first (often your weakest lines are last).
- Replace long phrases with shorter ones (keep meaning, change structure).
- Re-check after adding hashtags, links, and emojis.
Next, we will cover why counts differ between platforms and the mistakes that cause surprise over-limits.
Schedule captions that fit character limits
Draft, adjust, and schedule posts without guessing your character count.

If your character counter says you are under the limit but the platform still rejects your text, one of these is usually the reason:
- Hidden characters: non-breaking spaces, soft hyphens, or copy/paste artifacts from PDFs and slides can add length without looking like it.
- Smart punctuation: curly apostrophes and quotes are different characters than plain ones and can change counts across tools.
- Line breaks: some editors count each line break as a character, and some turn multiple spaces into one (or the opposite).
- Emoji composition: a single visible emoji can be multiple underlying characters, so different counters can disagree.
Fix it fast: paste your text into a plain-text editor first, remove extra line breaks, and keep a 10-30 character safety margin when you are close to the edge.
How major platforms count characters (and what to do about it)
X
X posts are typically capped at 280 characters, but X also supports longer posts (up to 25,000 characters) for eligible accounts. X applies special counting rules for some Unicode characters, emojis, and URLs, so a simple counter can be slightly off when you are right at the limit. The practical move is to leave a buffer and avoid stacking many emojis or long URLs at the end.
LinkedIn posts cap at 3,000 characters. In practice, the easiest way to stay safe is to keep your hook and first 1-3 lines short and punchy, then place optional context below. This also helps readability.
Instagram and TikTok
Instagram captions are commonly capped at 2,200 characters and often truncate in the feed, so put your most important words first. TikTok limits can vary by account and posting method; some business/API publishing flows enforce a 2,200-character limit even if native posting allows more. If you schedule posts, always test one long caption natively before you build your workflow around it.
YouTube
YouTube titles have a 100-character cap and descriptions cap at 5,000 characters. Descriptions can overflow quickly if you add credits, affiliate disclosures, or a long list of links, so consider putting the full list on a webpage and linking to it instead.
Mistakes to avoid when counting characters
- Counting in the wrong mode: if the platform counts spaces, use 'with spaces'.
- Forgetting hashtags and mentions: add them before the final check, not after.
- Copying from rich text: it can bring hidden formatting that adds characters.
- Over-optimizing for the exact limit: hitting 280 exactly is less useful than writing something people want to read.
A practical workflow for turning one draft into many lengths
- Write the full version first (the one you would publish with no limit).
- Make a 'short' version by removing context, not meaning.
- Make a 'tiny' version by keeping one point and one call to action.
- Run each version through your character counter with spaces.
- Save each version with a label like 'X-280', 'LinkedIn-3000', 'IG-2200'.
If you publish often, the real time sink is not counting. It is rewriting and reformatting for each platform.
When a tool helps (without replacing good writing)
If you manage multiple accounts or repurpose the same idea across networks, Ocoya can save time by helping you draft and schedule captions that respect platform limits. It is a good fit for creators and social teams who want to move faster without turning every post into a spreadsheet.
- Draft captions quickly, then adjust length per platform.
- Schedule across accounts so you are not copying and pasting all day.
- Keep your writing workflow consistent, even when limits differ.
You can use it as a next step after you learn the basics here: create captions that fit each platform's character limit.
FAQ
Do spaces count as characters?
Usually, yes. Most social platforms and form fields count spaces, so 'characters with spaces' is the number you should watch unless the field says otherwise.
Do emojis count as one character?
Not always. Some emojis are made of multiple Unicode parts, and some platforms apply special counting rules. If you are close to a limit, remove a few emojis or keep a safety margin.
Why does my character count differ between tools?
Tools can disagree on what to count: line breaks, non-breaking spaces, smart punctuation, and emoji sequences. When accuracy matters, use a plain-text workflow and check against the platform itself.
How do I count characters in Google Docs?
Go to Tools > Word count. It shows characters with spaces and without spaces, and you can enable a live word count while typing.
How do I count characters in Excel or Google Sheets?
Use LEN(cell) to count characters in a cell. If you need to ignore spaces, you can remove them first, then count.
What is the difference between characters with spaces and without spaces?
'With spaces' counts every space and line break. 'Without spaces' removes spaces from the total. Most character limits use the with-spaces number.
What should I do if I am one character over the limit?
Delete the least important words first, then tighten phrases. If you are still stuck, remove extra line breaks, swap long words for shorter ones, and keep your link or hashtag list minimal.
Conclusion
A character counter is simple, but it saves real time: you avoid failed submissions, broken captions, and last-minute rewrites. Use characters with spaces as your default metric, keep a small buffer near the limit, and paste as plain text when counts look weird. If you publish across networks often, build a small library of short and long versions so you are never starting from zero.
