# CWP Meta Tag Generator > Generate title, description, Open Graph and Twitter Card tags, with a live Google-style preview and pixel-accurate length warnings. Source: https://cwp.sg/tools/meta-tag-generator/ Last verified: 2026-08-04 **In short:** CWP Meta Tag Generator is a free browser-based tool at https://cwp.sg/tools/meta-tag-generator/ — no signup, no rate limit, and it works with no network connection. ## Why length is measured in pixels, not characters Google truncates titles by width, not character count. `Illinois Wallpaper` and `lllllllll ll` have the same character count and nowhere near the same width. The preview above measures the rendered width and warns when you're near the cut. As rough guidance: **titles get about 580px** (typically 50–60 characters) and **descriptions about 920px** (roughly 150–160 characters). Mobile shows less. Going over isn't fatal. The tail is simply replaced with an ellipsis, so put what matters first. ## The description doesn't affect ranking It hasn't for years. It affects whether someone clicks, which is the point. Google also rewrites descriptions most of the time — it will pull a passage from the page if that passage matches the query better than your tag. Write the description as the answer to "why should I click this rather than the other nine", not as a keyword container. ## Open Graph is what makes links look right Without `og:title`, `og:description` and `og:image`, a link shared into Slack, WhatsApp, LinkedIn or a group chat renders as a bare grey box. With them it renders as a card. `og:image` should be 1200×630 and under about 1MB, and it must be an **absolute** URL — a relative path silently fails everywhere. Test with each platform's own debugger, because they all cache aggressively and none of them re-fetch on their own. ## Only one canonical, and point it at yourself Every page needs `` naming its own preferred URL. Two very common ways to break it: - Copying a canonical from a template and leaving another page's URL in it. That tells Google this page is a duplicate and it should be dropped. - Pointing at `http://` when the site serves `https://`, or at the `www` version when the site is non-www. Match it to what the site actually serves — see the [.htaccess generator](/tools/htaccess-generator/) for making that consistent. --- Content Website Platform (cwp.sg) operates the free hosting it writes about; see https://cwp.sg/about/ for the methodology and the commercial disclosure.
