og:image dimensions are off
Your og:image is not close to 1200 × 630. Here is what each platform does with an off-ratio image and why below 600 × 315 downgrades your card entirely.
What you are seeing: Your image appears cropped, letterboxed with bars, or shrunk into a small square thumbnail beside the text instead of filling the card.
The target is 1200 × 630
1200 × 630 pixels is a 1.91:1 landscape ratio, and it is what Facebook, LinkedIn, X, Discord and Slack all design their large card layouts around. Hitting it exactly means no platform has to crop or pad your image to make it fit.
The pixel count matters as well as the ratio. 1200 wide is enough to stay sharp on high-density displays without pushing the file size up unnecessarily.
What goes wrong off-ratio
Too tall and platforms crop the top and bottom to reach 1.91:1. Anything centred vertically survives; anything near the edges is cut. This is how logos and headline text disappear from otherwise fine-looking cards.
Too wide and you get the same crop on the left and right, or letterboxing with grey bars depending on the platform.
Below roughly 600 × 315 the behaviour changes completely: rather than scaling your image up, most platforms abandon the large card and fall back to a small square thumbnail next to the text. That is a much bigger visual downgrade than a crop, and it is the case worth fixing first.
Designing for the crop
Even at the right ratio, assume the outer edges may be trimmed. Keep text and logos inside a safe area roughly 100 pixels in from each edge, and do not put anything load-bearing in a corner.
Test at small sizes. A card that reads well at full width often becomes illegible in a WhatsApp thread or a mobile feed, where it may render under 400 pixels wide. If the headline is not readable there, it is too small.
Frequently asked
What is the minimum og:image size?
600 × 315 is the practical floor for a large card. Below that, Facebook and LinkedIn switch to a small thumbnail layout. 1200 × 630 is the recommended size and gives you headroom on high-density screens.
Do square images work?
They render, but not well. A 1:1 image gets centre-cropped to 1.91:1 on most platforms, so you lose roughly half the height. If you only have a square asset, place it on a 1200 × 630 canvas with padding rather than letting the platform crop it.
