Text Pixel Width Calculator
Type or paste text and see exactly how wide it renders in pixels for a given font, size, and weight — the actual missing piece when a character-count limit alone isn’t enough.
Character counts are a rough proxy at best for how wide text actually renders, since different characters take up very different amounts of horizontal space (a lowercase “i” versus an uppercase “W” can differ by several times the width). This matters directly for things like meta title tags, where Google truncates based on approximate pixel width rather than a fixed character count, meaning a shorter title full of wide characters can still get cut off while a longer title of narrow characters fits fine.
Type your text, select the font family, size, and weight you’re targeting (or match a specific platform’s known rendering font, like Google’s search result title font), and see the exact pixel width calculated live. A visual ruler or bar shows the width against a common target limit, making it immediately clear whether your text fits.
Frequently asked questions
Why does Google truncate my title tag even though it’s under the character limit I was told to follow?
Google’s search result title truncation is based on approximate pixel width, not a fixed character count, which is exactly why a character-count guideline is only ever a rough approximation — a title using wider characters (many capital letters, wide letters like “m” and “w”) can get cut off well before hitting a character-count limit that assumed narrower average character width.
Does the calculation account for different browsers rendering fonts slightly differently?
It uses standard font metrics for the selected font, which is accurate for the vast majority of practical purposes, though extremely minor sub-pixel rendering differences can exist between browsers and operating systems — for anything highly precision-critical, a final visual check in your actual target context is still worth doing.
Can I check width for a custom or unusual font, not just common system fonts?
The tool includes common system and web-safe fonts along with popular web fonts; a genuinely custom or self-hosted font outside that list isn’t supported directly, since accurate pixel width depends on the font’s actual metrics being available to measure against.
Is this only useful for SEO titles, or does it help with other things too?
It’s useful anywhere fixed-width space matters — UI button labels, navigation menu items, or any interface element where text needs to fit within a defined pixel width without wrapping or overflowing.
