Perfect title, 72 characters, truncated mid-keyword on every SERP. Perfect description, 178 characters, cut before the call to action. The author counted characters; Google measures pixels. A 55-character title near 540px stays green; the same count in wide capitals near 660px bleeds red. This guide gives the pixel budgets that actually govern truncation in 2026, why mobile clips earlier, and why Google rewrites titles no matter what you do.

Pixel budgets (not character counts)
| Element | Safe | Caution | Truncated |
|---|---|---|---|
| Title | 50–55 chars (~480–540px) | 62 chars (~595px amber) | 70+ chars (~650px+) |
| Description | 150–155 chars (~880px) | 165 chars (~940px) | 178+ chars (~990px+) |
Character width varies: W and emojis consume far more than i, l or hyphens. Two 55-char titles can differ 100px in render. Always validate in a pixel meter, never by count alone. Front-load keywords within the first 40 characters — mobile viewports clip hardest, and favicon plus date stamps steal additional room on real SERPs.
Mobile clipping and Google rewrites
Mobile shows ~40 characters of title before cutting — put the value words first or mobile searchers never see them. And accept what you cannot control: Google rewrites 60%+ of titles (site-name appends, keyword swaps, date injections). Rewrites favor pages with clear H1s and descriptive links — which the 60-to-80 rescue covers. When your crafted title gets replaced, improve H1/heading alignment rather than re-tuning characters.
Workflow: draft, meter, generate, re-verify
- Draft title (keyword fronted) + description (benefit + CTA) in the meta tag generator.
- Meter both in the SERP preview — green bars at 540px/880px before anything ships.
- Generate the head block and paste once near the top of
<head>. - Re-verify after template or font changes — pixel widths shift silently with typography.
General guidance only. Pixel budgets drift as Google restyles SERPs — re-meter quarterly, not once.
