How to Use

1. Configure your page title, target URL, and meta description in the Content fields. 2. Adjust thresholds, accent color, border radius, and display options in the Design and Settings groups. 3. Preview the generated Bootstrap 5 results card — it shows character count, pixel-width estimate, status badge, and SERP snippet simulation. 4. Copy or download the HTML and drop it into any Bootstrap 5 project or documentation page.

Why Use This Tool?

Manually counting title tag characters wastes time and still misses the real constraint — Google truncates by pixel width, not character count, so a title with 55 narrow characters can be fine while 50 wide characters get cut. This tool calculates both metrics simultaneously, generates a shareable results card, and requires zero npm installs, APIs, or logins — just paste a title and get an answer.

Frequently Asked Questions

What is the Title Tag Length Checker?

It's a free online tool that measures your HTML title tag against Google's display limits — both character count and estimated pixel width — and generates a visual Bootstrap 5 results card showing pass/fail status and a SERP snippet preview.

Why does pixel width matter more than character count?

Google renders page titles in a fixed-width container of approximately 600px using a proportional font (similar to Arial). A title composed of wide characters like 'W', 'M', and uppercase letters can exceed the display limit at just 50 characters, while narrow characters like 'i', 'l', and 'f' allow longer titles. This tool estimates pixel width using average character-width ratios, giving you a far more accurate truncation prediction than a raw character count ever could.

Is it free?
