My Twitter Photo Card is just 240px wide

[quicoto]

Hi there,

My Twitter Cards have been approved for quite a while. I’ve noticed that my Photo Cards are just 240px wide (?)

The original source is way bigger (1024px) but the preview Twitter generates it’s always 240px.

I’ve looked at tweets from @mashable and they have bigger previews 480px to be exact.

Mashable: https://twitter.com/mashable/status/356664168121769984

Mine: https://twitter.com/quicoto/status/356459904770387970

I’ve tried passing a smaller original image (like Mashable) a 560px image but it still previews a 240px.

Any idea why?

Thanks in advance

I’m having this issue as well:

Yep, and using a retina display (iPhone) it just looks a little blurry
