Google measures width, not letters
Desktop result titles are set in Arial at 20px inside a box roughly 600 pixels wide. When the text runs out of room, Google cuts it at a word boundary and adds "…". Because every letter has a different width, the number of characters that fit changes from title to title.
Drag the cutoff and switch between the presets to see it: narrow letters like i, l and t pack in far more characters than wide capitals like W and M.
57 characters = 551px. Fits with 49px to spare.
Title length reference
| Element | Guideline | What happens if longer |
|---|---|---|
| Title tag (desktop) | ≤ ~600px · 50–60 characters | Truncated with "…"; may be rewritten |
| Title tag (mobile) | Can wrap to two lines | Truncated after the wrap |
| Meta description | ≤ ~920px · 140–155 characters | Truncated; Google may use page text instead |
| H1 headline | 6–12 words | No cutoff, but harder to scan |
| YouTube title | ≤ 100 characters allowed; ~50–70 shown | Cut in feeds and search |
| Email subject | ~30–50 characters | Phones show about 35–40 |
Writing to fit
- Put the keyword and the benefit in the first 40 characters so they survive any truncation.
- Drop filler like "The Ultimate" or "Everything You Need to Know About" before cutting meaning.
- Use a short brand suffix (or none): Google already shows your site name above the result.
- Check the exact width with the SEO title checker, which previews desktop and mobile results.
