Google Doesn't Truncate Titles by Character Count — It's Pixel Width
You've probably heard the advice "keep your SEO title under 55 characters" from just about everywhere. But if you take that number literally and write a Korean title at exactly 55 characters, it shows up in search results cut off less than halfway through, ending in "...". That's because what Google actually truncates on isn't character count — it's the horizontal width the title renders at on screen, in pixels. And full-width characters like Korean take up far more screen space than Roman letters do.
1. "55 characters" is only a Roman-letter approximation
The actual width of the title area in Google search results is known to be roughly 580px. Dividing that 580px by the average character width of a Latin font gives you roughly 50-60 characters, which is how the "keep titles under 55 characters" rule of thumb spread. But that number only holds if you assume Roman letters (a, b, c...) — the real standard Google uses is the pixel width itself. Load up on narrow letters like i and l, and you can go past 60 characters without being cut off; load up on wide letters like m and w, and you might get cut off before 50.
2. Why Korean, Chinese, and Japanese truncate so much faster
Characters like Korean, Chinese, and Japanese are called full-width characters in typography terms. Fonts are designed so that these characters render at roughly twice the width of Roman letters on screen. So filling that same 580px limit entirely with full-width characters means only about 28-30 characters fit — half the count that 50-60 Roman letters would take up. If you take the "55 English characters" rule at face value and write a Korean title that long, you'll already have blown past the width limit well before the end, and the tail of the title shows up cut off with "..." in search results.
| Language / character type | Relative width per character | Approx. character count at 580px |
|---|---|---|
| Roman letters (English) | 1x (baseline) | ~50-60 chars |
| Korean/Chinese/Japanese (full-width) | ~2x | ~28-30 chars |
| Digits and symbols (half-width) | ~1x | Similar to Roman letters |
3. How to calculate a mixed-language title
For a title that mixes Korean and English, a common approximation used in practice is to count full-width characters (Korean, Chinese, Japanese) as 2 width units and half-width characters (Roman letters, digits, symbols) as 1 width unit, then add them up. For example, a title like "2026 연말정산 완벽 가이드," mixing 12 Korean characters with digits and spaces, gets much closer to the 580px limit at a far lower total character count than a pure-English title would. The site's own SEO Title Generator applies this same width weighting when it generates each candidate title, showing a real-time color status of "good / a bit long / too long."
4. Summary
- Google truncates by pixel width (~580px): character count is just a Roman-letter approximation of that width.
- Korean, Chinese, and Japanese are about twice the width of Roman letters: within the same 580px limit, they truncate at a much lower character count (~28-30 characters).
- Applying the "55-character rule" directly to Korean titles is risky: the tail end can get cut off in real search results, hurting click-through rate.
- Mixed-language titles: weight full-width as 2 units and half-width as 1 unit: this gets you close to an accurate width estimate.
Frequently Asked Questions
Q. Exactly how many characters does a Google title show before truncating?
A. There's no fixed character count. Google truncates based on the rendered horizontal width (in pixels) of the title, and that limit is roughly 580px for Roman text — which converts to about 50-60 characters. But that number is only an approximation based on Roman letters; the actual cutoff point depends on which alphabet is used.
Q. Do Korean titles also show up to 50-60 characters?
A. No. Full-width characters like Korean, Chinese, and Japanese take up roughly twice the screen width of Roman letters. Filling the same 580px limit with full-width characters starts truncating at around 28-30 characters — about half the Roman-letter count. Applying an "English character count" rule directly to a Korean title creates a trap: you end up writing a title that's actually much longer than it should be.
Q. Why does Google use pixel width instead of character count as the standard?
A. Because the point where a search result title actually gets cut off is the physical width it renders at on screen, not the number of characters. Letter width varies (i and l are narrow, m and w are wide), and character width varies by language too, so a fixed rule like "55 characters" can't produce an accurate cutoff point across every language and font combination. Google calculates the actual rendered width to keep a consistent visual truncation line.
Q. How do you calculate the limit for a title that mixes English and Korean?
A. A common approximation used in practice is to count full-width characters (Korean, Chinese, etc.) as 2 units of width and half-width characters (Roman letters, digits, symbols) as 1 unit, then sum them. A title made up of 10 Korean characters plus 10 English characters scores (10×2)+(10×1)=30 width units — a visual width similar to 15 pure Korean characters (also 30 units).
Q. Does a truncated title hurt search rankings?
A. Truncation itself isn't a ranking factor, but if a key keyword or brand name ends up in the cut-off part, users have a harder time deciding whether to click, which can lower click-through rate (CTR). CTR is known to be a signal that can indirectly influence rankings over time, so it's safest to put the most important information near the front of the title.
Q. Does the same pixel-width rule apply to meta descriptions?
A. Yes — descriptions are also truncated by pixel width rather than a fixed character count. That said, Google frequently swaps in an excerpt from the page body that better matches search intent, so the description you write may not always be what's shown.
Q. Does the truncation point differ between mobile and desktop?
A. Yes. Mobile screens are narrower than desktop, so the title display area is often given a narrower pixel width as well, meaning the same title can get cut off earlier in mobile search results.
Q. How does this site's SEO Title Generator account for this width calculation?
A. Each generated title candidate card shows a character count along with a color-coded status based on width weighting (good / a bit long / too long). Korean, Chinese, and Japanese titles count full-width characters as 2 units, so a "too long" warning can appear at a much lower character count than it would for a Roman-letter title.
