A character counter tallies every letter, number, punctuation mark, and space in your text. Platforms like Google, Twitter/X, LinkedIn, and SMS all enforce strict character limits. A character counter ensures your content fits perfectly — without guessing or being cut off mid-sentence.

A character counter is a utility that counts every single unit of text in a string — including letters, digits, punctuation marks, spaces, and line breaks. Unlike a word counter, which groups tokens by whitespace, a character counter operates at the most granular level of text.
Most platforms that enforce text limits — from social media networks to search engines — measure those limits in characters, not words. This is because character count is a consistent unit across languages. A Japanese haiku and an English sentence with the same number of characters take up roughly the same space on screen, whereas word count varies wildly by language.
The WordCountNow word counter reports characters with and without spaces simultaneously, so you can match whichever metric a given platform requires.
Understanding the character limits of the platforms you write for prevents truncation and ensures your message lands as intended.
| Platform / Field | Character Limit | Notes |
|---|---|---|
| X (Twitter) post | 280 | URLs count as 23 chars regardless of length |
| Instagram caption | 2,200 | Only first 125 visible before "more" |
| LinkedIn post | 3,000 | ~210 visible before "see more" on feed |
| Facebook post | 63,206 | Engagement drops sharply after ~400 |
| Google meta title | ~60 | ~600 px width; varies by device |
| Google meta description | ~155 | ~920 px on desktop; ~680 px on mobile |
| Google Ads headline | 30 | 3 headlines per responsive ad |
| Google Ads description | 90 | 2 descriptions per responsive ad |
| SMS (single segment) | 160 | Multi-part SMS starts at 153 per segment |
| WhatsApp message | 65,536 | No practical limit for everyday messaging |
| YouTube title | 100 | ~70 shown in search results |
| YouTube description | 5,000 | First 150 visible without "Show more" |
| Pinterest pin title | 100 | Only first 30–40 visible in feed |
| TikTok caption | 2,200 | Hashtags count toward the limit |
When you paste text into a character counter, you will often see two numbers: characters with spaces and characters without spaces. Understanding which to use matters:
When in doubt, read the platform's own documentation. Most will specify "characters" without qualification, meaning they include spaces.
Character count is critical for two of the most important on-page SEO elements: the meta title and meta description.
Google measures meta titles in pixels, not characters — but at a standard font size, roughly 60 characters is the safe limit before titles are truncated in search results. A truncated title looks unprofessional and may omit the most important keyword. Keeping your title under 60 characters with meaningful keywords placed early maximises click-through rate.
Meta descriptions are also measured in pixels by Google. On mobile, approximately 120 characters is the practical maximum; on desktop, around 155–158 characters. Writing a compelling description that fits within this range gives you a full "billboard" in search results rather than a cut-off sentence.
While Google does not enforce character limits on H1 or H2 tags, search results snippets and social preview cards that pull heading text will truncate anything overly long. Concise headings that communicate value quickly tend to perform better both for users and for rich snippets in search.
Research consistently shows that shorter posts outperform longer ones on most platforms — up to a point. Knowing your character count helps you write copy that is exactly long enough to inform and persuade, but not so long that it loses readers.
Yes, by default most character counters include spaces. Many also offer a "characters without spaces" metric, which is useful when the platform specifies characters excluding spaces.
X (formerly Twitter) allows 280 characters per post for standard accounts. URLs are always shortened to 23 characters regardless of their actual length. Images, videos, and polls do not consume character count.
Google typically displays 120–158 characters in mobile search results and up to around 920 pixels wide on desktop. Aiming for 150–155 characters avoids truncation on most devices.
Visually, emojis appear as one character. However, in terms of bytes (UTF-8 encoding), most emojis are 3–4 bytes. Most platforms count emojis as 1–2 characters depending on their implementation. Twitter counts most emojis as 2 characters.
