SERP pixel width checker

Google truncates search result titles and meta descriptions by pixel width, not by character count. A 60-character title full of wide letters like W and M can overflow while a 65-character one full of narrow letters like i and l still fits. This checker estimates the rendered width so you can trim a snippet to the exact edge of what Google shows, instead of guessing from a character limit that behaves differently for every string.

Paste a title or a description and pick the element. Titles are measured at 20px Arial against a truncation point near 580px; descriptions at 14px Arial against roughly 920px. These are the widely-cited limits for Google's desktop results — approximate, because the real cutoff shifts with the device, the query, date prefixes and layout changes on Google's side. The tool reports the estimated width, whether it fits or by how many pixels it is too long, and the character count, and it measures the first non-empty line so you can keep several drafts stacked in the box.

The width comes from a built-in Arial advance-width table, the font family Google renders results in. Characters outside the table fall back to an average glyph width, so accented and non-Latin text still produces a sensible estimate rather than an error. Treat the number as a close guide, not a pixel-perfect promise: use it to catch titles that clearly overflow and to fine-tune ones sitting near the edge.

Everything runs locally in your browser. Your titles and descriptions are never sent to a server, so you can measure drafts for unpublished pages, client work or internal tools without exposing a word of them.

FAQ

Why measure pixels instead of characters?
Google cuts titles and descriptions off at a pixel boundary, and every letter has a different width — 'W' is roughly four times as wide as 'i' in Arial. Two titles with the same character count can render very differently, so a pixel estimate predicts truncation far better than a character limit does.
What are the pixel limits?
Titles are measured at 20px Arial with a truncation point around 580px, and descriptions at 14px Arial with a limit near 920px. These are the commonly cited figures for Google desktop results; mobile and the live SERP can differ.
Is the width exact?
No. It is an Arial-based estimate from a built-in advance-width table. Google's real rendering depends on the exact font build, the device, the query, date prefixes and periodic layout changes, so treat the result as a close guide rather than a pixel-perfect measurement.
Which line does it measure?
The first non-empty line, trimmed of surrounding spaces. A title or description is a single line, so you can keep several variants on separate lines in the box and only the first one is measured.
Is my text uploaded anywhere?
No. The measurement runs entirely in your browser and your titles and descriptions never leave your device, so drafts for unpublished or internal pages stay private.
