Localecheck

A title written to fit English is not the same width in German. The same sentence measures 454 pixels in English, 641 in German, 686 in Japanese and 735 in Russian.

Localecheck measures the string the way a renderer does: Arial at Google's own sizes, 580 and 920 pixels on desktop, 560 and 680 on mobile. It reports the width, the share of the budget in use, and the character where the cut lands, so you know which clause to shorten rather than guessing.

Six tools, all free, all in the browser: title and description width across 20 languages, a batch audit for crawler exports, CJK full-width counting, keyword table checks, and two hreflang tools. Nothing you paste leaves the tab. The only paid part is AI rewrites.
