Letter Counter — Free Character & Word Count Tool

How to Count Characters and Words Online

Whether you're crafting the perfect tweet, optimizing a meta description, or tracking your essay's word count, knowing your character and word counts in real time saves you from frustrating surprises. Letter Counter gives you an instant, complete breakdown of your text — no sign-up, no limits.

Characters with spaces is the number most social platforms and CMS tools use when enforcing limits. Characters without spaces removes all whitespace so you can compare content density. Words counts any sequence of characters separated by whitespace — hyphenated words like "well-known" count as one word. Sentences are detected by period, exclamation mark, or question mark followed by whitespace. Paragraphs are blocks of text separated by blank lines.

Reading time uses 250 words per minute — the average adult speed for non-fiction. Speaking time uses 130 words per minute, appropriate for presentations and podcasts. A 500-word article takes about 2 minutes to read and 4 minutes to speak aloud. Knowing these numbers helps content creators and speakers plan accordingly.

Byte size shows how many bytes your text occupies in UTF-8 encoding — the standard on the modern web. English text is 1 byte per character. Accented and most European characters are 2 bytes. Chinese, Japanese, and Korean characters are typically 3 bytes. This matters when you work with APIs, databases, or storage systems that enforce byte-based limits.

The top words panel filters common stop words and shows which terms you use most often. Writers use this to spot repetition and improve vocabulary variety. SEO professionals use it to verify that target keywords appear naturally in their copy.

Platform-Specific Character Counters

Each platform enforces its own rules. Use a dedicated counter when you need precise limit tracking:

Twitter Character Counter — 280-character limit; URLs always count as 23 regardless of length
SMS Character Counter — 160 GSM-7 characters per segment; drops to 70 when emoji or non-GSM characters appear
Instagram Caption Counter — 2,200-character cap; only the first 125 show in the feed before truncation
Meta Description Checker — 160 characters before Google truncates in search snippets
SEO Title Checker — 60 characters before search engines rewrite or shorten your title tag

Using Presets to Hit Limits on the First Draft

Click any preset button and a progress bar appears beneath the text field showing exactly how much of your budget you have used. The bar turns red as you approach the limit. Switch presets freely — the bar recalculates instantly so you can compare, for example, whether your copy fits both a tweet and an SMS at the same time without reloading the page.

Pick the right preset for the job: use Tweet (280) when writing for Twitter/X, keeping in mind URLs always consume a fixed 23 characters regardless of their actual length; use Title tag (60) or Meta desc (160) when optimizing search-engine snippets; use Instagram (2,200) to verify your caption fits, remembering only the first 125 characters are visible in the feed without a "more" tap; use SMS (160) when composing message templates sent to a carrier network.

Common Gotchas That Catch Writers Off Guard

Emoji count as 2 characters on Twitter/X — a single ❤️ and a short sentence can push you past 280 faster than expected. Pasting a link into a tweet? Twitter/X shortens every URL to a t.co link that always occupies exactly 23 characters in the count, whether the original URL is 10 characters or 200. For SMS, adding even one emoji or a smart quote (the curly " marks that word processors insert automatically) silently switches the message from GSM-7 encoding — 160 characters per single message, 153 per segment in multi-part messages — to UCS-2 encoding, which drops you to 70 characters per single message and 67 per segment. That means a single emoji can reduce a 5-segment SMS campaign from 765 usable characters down to 335 without any visible warning. Letter Counter's SMS preset counts characters; use the dedicated SMS Character Counter to see your exact segment breakdown.

Frequently Asked Questions

How many characters is a tweet?

Twitter (X) allows up to 280 characters per tweet, including spaces and punctuation. URLs always count as 23 characters regardless of their actual length.

What is the character limit for a meta description?

Google typically displays the first 150–160 characters of a meta description in search results. Keeping your meta description under 160 characters ensures it is shown without truncation and improves click-through rates.

How many characters can an Instagram caption be?

Instagram captions support up to 2,200 characters. However, the feed truncates captions after about 125 characters — put your most important text first so it shows without requiring a tap.

What is the character limit for an SMS text message?

A single SMS supports up to 160 characters using standard GSM encoding. Messages longer than 160 characters are split into multiple segments of 153 characters each, with each segment counting as a separate SMS credit.

How is reading time calculated?

Reading time is estimated at 250 words per minute — the average adult reading speed for non-fiction content. A 500-word article takes about 2 minutes; a 1,000-word blog post takes roughly 4 minutes.

What is the difference between characters with and without spaces?

Characters with spaces counts every character including spaces, tabs, and newlines. Characters without spaces counts only visible characters — letters, numbers, and punctuation — with all whitespace removed. Social platforms typically count spaces toward your limit.

How many characters should an SEO page title have?

Search engines typically display 50–60 characters of a page title tag. Titles longer than 60 characters get truncated with an ellipsis in search results, which can hurt click-through rates.

How many characters fit in a YouTube description?

YouTube video descriptions support up to 5,000 characters. Only the first 100–125 characters appear above the Show More fold in the mobile app and in Google search result snippets — front-load your keyword and call-to-action there.

What is the character limit for a LinkedIn post?

LinkedIn posts support up to 3,000 characters. The feed displays approximately the first 210 characters before a see more link. Lead with your strongest sentence to encourage readers to expand the post.

How long can a Bluesky post be?

Bluesky limits posts to 300 characters — the same as Twitter's original limit. Unlike Twitter/X, Bluesky URLs count toward the 300-character limit without shortening, so factor in link length when composing posts.

What is the difference between a letter and a character?

A letter is a member of an alphabet (A–Z), while a character is any symbol — including digits, punctuation, spaces, and emoji. Most platforms enforce limits by character count, not letter count. This tool counts all characters, not only alphabetic letters.

Why does my SMS get split into multiple texts?

Standard SMS uses GSM-7 encoding, which allows up to 160 characters per segment. If your message contains any character outside GSM-7 — such as emoji, smart quotes, or accented letters not in the GSM set — the message switches to UCS-2 encoding, dropping the per-segment limit to 70 characters. Multi-segment messages also reserve bytes for concatenation headers, reducing usable characters to 153 (GSM-7) or 67 (UCS-2) per segment.

Does emoji count as one character?

It depends on the platform. Most social platforms, including Twitter/X, count each emoji as 2 characters because emoji are encoded as UTF-16 surrogate pairs. Some platforms count each emoji as 1. This tool uses JavaScript's standard string length, which counts surrogate pairs as 2 — matching Twitter/X behavior.

How many words is 500 characters?

500 characters is approximately 80–100 words, assuming an average English word length of 5–6 characters plus a space. Shorter words push toward 100; longer technical terms push toward 80. This tool displays both your character count and word count simultaneously so you never need to estimate.

Can I count characters without spaces?

Yes. The stats panel shows Characters (with spaces) and Chars (no spaces) simultaneously as you type. Characters without spaces removes all whitespace — spaces, tabs, and newlines — leaving only visible characters. This is useful for measuring content density or comparing text with variable formatting.
