Every SEO tutorial repeats the same numbers: 60 characters for the title, 160 for the meta description. Those numbers are wrong, or at least incomplete. Google truncates titles at roughly 580 pixels on desktop and ~920 pixels on mobile, not at a character count. A title with sixty narrow letters like "i" and "l" can render comfortably; a title with forty wide letters like "W" and "M" will get cut off mid-word. Character counts are a useful approximation, but if you have ever watched a 58-character title get truncated in the wild, this is why.
This counter does both. It shows you the character count so you can sanity-check against the conventional limits, and it estimates pixel width using Google's serif Arial-equivalent at the size the SERP actually uses. You paste your title, your description, your Twitter title, your Twitter description, all four at once, and watch each one go from green to amber to red as you write. The limit it enforces is the practical one: 60 characters or 580 pixels, whichever you hit first.
What people get wrong is treating the limit as a target. The optimal title length is "as short as it can be while still earning the click." If you can describe the page in 42 characters and have it match search intent, do that. Padding a 42-character title up to 58 characters with filler words ("Guide", "Complete", "Ultimate", "2026") buys you nothing except a slightly worse CTR. The same goes for meta descriptions: 120 characters that promise something specific beat 160 characters of vague summary every time.
Twitter card limits are the one place where the character count actually matters more than the pixel width: Twitter truncates by character at 70 for the title and 200 for the description, and it does so cleanly without ellipsis on some clients. If you write a Twitter title that runs to 75 characters, the last five words simply disappear in some feeds. The counter shows you both fields separately because Twitter and Open Graph have different rules and conflating them is a common mistake.
Use this tool the way a copywriter uses a word count, not the way a compliance officer uses a checklist. Get under the limit, then stop. Spend the remaining attention on whether the title is a promise you can keep, which is what actually moves CTR.
Verify titles and descriptions fit SERP display limits.
- What character limits does it enforce?
- Title tags 50–60 characters and meta descriptions 150–160, matching Google's typical desktop truncation points (~580 px and ~920 px).
- Does it count pixels or characters?
- Both. Google truncates by pixel width, so the counter shows character counts alongside pixel-width estimates (~580 px for titles, ~920 px for descriptions on desktop).
- Is there a limit on how much I can paste?
- No. Paste any length of text and the counter will report breakdowns for each SEO field.
- Why does my title look fine in the counter but get truncated on mobile?
- Mobile SERPs use a slightly different pixel budget, around 920 pixels for vertical phones, but with a smaller font that complicates the math. As a rule of thumb, if a title is comfortable on desktop at ~580 pixels, it survives mobile. Where it gets dicey is mobile in landscape, where some ancillary results panels narrow the title column further.
- Should I count characters or words when writing descriptions?
- Characters. Word count is a useful proxy for "feels long enough to be useful" but Google truncates by pixel and Twitter truncates by character, and neither cares how many words you used. A 25-word description and a 22-word description can render identically.
- Does Google ever show descriptions longer than 160 characters?
- Yes, occasionally. For queries where Google needs more context to disambiguate, you will see descriptions render at 200+ characters. You cannot reliably target this, and the 160-character limit is the safe planning number. Write for 155, and treat anything longer as a happy accident.
- Do special characters like dashes and pipes count the same as letters?
- For character counts, yes. One character is one character. For pixel widths, a hyphen is narrower than an M but wider than a period. The pixel estimate in this counter handles common punctuation correctly, but exotic Unicode characters (em-dashes, smart quotes, mathematical symbols) can render unpredictably across browsers.
- Why does my Twitter title get cut off at 50 characters in some apps?
- Twitter's official truncation is 70 characters for cards, but third-party clients and the in-app preview card on iOS sometimes show fewer. If your title needs to work in every Twitter surface, write to 50-55 characters. If you only care about web and the official app, 70 is fine.
- Is there an SEO penalty for going over the limit?
- No. There is no algorithmic penalty for a long title or description. The cost is purely UX: the truncated portion disappears, so if the most important word was at the end, you lose it. Going over the limit is a missed opportunity, not a violation.
- How accurate is the pixel width estimate?
- Within a few pixels of what Google actually renders, in our testing. The font Google uses in SERP titles is close to Arial at 20px, and the counter uses the same metrics. The places it can drift are rare characters and emojis, which render at different widths in different browsers and on Google's own SERP.
Counting characters is the easy part. The hard part is writing a title that earns the click while staying under the limit, and no tool can do that for you. What this counter does is take the math off your plate so you can spend your time on the words that matter.
