og:description is too long
Your og:description runs past the point where mobile previews truncate. Here is where the cut lands on each platform and how to tighten it.
What you are seeing: Your preview text ends in an ellipsis on phones, even though it looks complete on desktop.
Desktop is not the case to design for
Desktop cards on Facebook and LinkedIn will show around 200 characters, which is why an over-long description often looks fine when you test it. Mobile is narrower and gives you roughly 125 before it truncates, and messaging apps are tighter still — WhatsApp and Slack both cut earlier.
Since most link previews are seen on a phone or in a chat, the mobile limit is the real one.
How to tighten it
Lead with the payoff. If the sentence is going to be cut, the part that survives should be the part that earns the click.
Cut any restatement of the headline. The description sits directly beneath og:title and is read as a continuation of it, so repeating the same idea in different words wastes the whole line.
Drop the closing call to action. 'Learn more', 'Read the full guide' and similar phrases are the first things to be truncated and add nothing — the card is already a link.
Frequently asked
What is the safe og:description length?
Up to about 125 characters displays in full on essentially every platform including mobile. Between 125 and 200 will show on desktop and truncate on phones. Past 200 it is cut everywhere.
Is a truncated description actually a problem?
It is a small one, not a broken card. But an ellipsis mid-sentence reads as careless, and the words lost are usually the ones that were meant to persuade. It is a cheap fix.
