Meta Tag and Open Graph Preview
The title tag and meta description are the first thing a searcher reads. Open Graph and Twitter card tags control how a link looks when it is shared, so the page chooses its own title, text, and image. Platforms left to guess often show a cut-off title and a blank image.
Everything above runs in your browser and saves to this device only. Type a title, description, URL, and share image, and the previews update as you type. The HTML for the page head is ready to copy.
How it works
Search engines truncate by pixel width, so the tool measures width as well as characters.
Description: about 920 pixels at 14 px Arial, roughly 150 to 160 characters
Share image: 1200 by 630 pixels, a 1.91 to 1 ratio
These limits are approximations. Search engines sometimes rewrite titles and descriptions, so the preview shows the most likely result.
Frequently Asked Questions
What are meta tags and Open Graph tags?
Meta tags describe a page to search engines, chiefly the title tag and the meta description. Open Graph tags tell Facebook, LinkedIn, and other platforms which title, description, and image to show when the page is shared. Twitter card tags do the same for X.
How long should a title tag be?
A title tag should fit about 600 pixels in search results, roughly 50 to 60 characters. Put the most important words first, since longer titles are cut off.
How long should a meta description be?
A meta description should fit about 920 pixels, roughly 150 to 160 characters. Search engines may rewrite it, but a clear summary that matches the page is usually kept.
What size should an Open Graph image be?
An Open Graph image should be 1200 by 630 pixels, a 1.91 to 1 ratio. With one, a shared link shows a large preview card. Most platforms fall back to a small or empty preview when the image is missing.
Is this Meta Tag and Open Graph Preview free?
Yes. The Meta Tag and Open Graph Preview is free and opens straight away in any modern browser, including on a phone. A share image loads from the address you enter, as it would on any web page.
