Direct Answer
Open Graph tags are the broad social-preview standard used by platforms such as WhatsApp, LinkedIn, Slack, Discord, Facebook, and many messaging apps. Twitter Cards are X/Twitter-specific tags that give you extra control over card type and X presentation. Developers should usually include both.
Test the combined setup with the Open Graph preview tool and the Twitter/X card preview tool.
The Core Difference
Open Graph describes the page for broad social sharing:
<meta property="og:title" content="Your title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="https://example.com/og.jpg" />
<meta property="og:url" content="https://example.com/page" />Twitter Cards describe how X should render the card:
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Your title" />
<meta name="twitter:description" content="Your description" />
<meta name="twitter:image" content="https://example.com/og.jpg" />The tags overlap, but they are not identical. The most important unique tag is twitter:card, which controls the card type on X.
What Happens If You Only Use Open Graph?
Many platforms will work. WhatsApp, LinkedIn, Slack, Discord, and Facebook primarily rely on Open Graph. X can also fall back to Open Graph for title, description, and image.
The risk is card control. Without twitter:card, X may not render the large image card you expect. For launch posts and image-heavy content, that is enough reason to add Twitter Card tags.
What Happens If You Only Use Twitter Cards?
Your X preview may work, but other platforms can fail. WhatsApp and LinkedIn do not treat Twitter Card tags as the main source of truth. If og:title, og:description, and og:image are missing, those apps may show weak or blank previews.
For broad compatibility, Open Graph should be the foundation.
Recommended Developer Setup
Use one canonical social title and image unless you have a strong reason to customize by platform:
<meta property="og:title" content="Launch title" />
<meta property="og:description" content="Short launch summary" />
<meta property="og:image" content="https://example.com/og-launch.jpg" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:url" content="https://example.com/launch" />
<meta property="og:type" content="website" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Launch title" />
<meta name="twitter:description" content="Short launch summary" />
<meta name="twitter:image" content="https://example.com/og-launch.jpg" />This gives every platform usable data while keeping maintenance simple.
When to Customize Twitter Tags
Customize Twitter Card tags when the X audience needs a shorter title, different framing, or an image crop that works better in the X feed. Keep the canonical URL and core brand message aligned so analytics and previews do not drift.

FAQ
Q: Are Twitter Cards the same as Open Graph tags?
A: No. They overlap, but Twitter Cards are X-specific and Open Graph is the broader social-preview standard.
Q: Does X use Open Graph tags?
A: X can use Open Graph fallbacks for title, description, and image, but twitter:card controls card type.
Q: Should I duplicate every OG tag as a Twitter tag?
A: You do not have to duplicate every field, but including Twitter Card tags gives better control over X previews.
Q: Which should I test first?
A: Test Open Graph first for broad platform coverage, then test Twitter/X cards for X-specific card layout.
