How can I make my thumnail proper?

First of all you’ll need to use a Summary Card with Large Image instead of a summary card. Then you’ll need to use an appropriate image.

Hey Andypiper I’ve embedded the summary card with large image.
The validator shows the large thumbnail even I am getting proper thumbnail on home page while posting on
Twitter but the blog post are not displaying a proper thumbnail or its fetching the thumbnail of home page rather than it original thumbnail.
Please let me know where I am going wrong.
How can I correct it

Take a look at the specifications for valid image sizes for the summary large image card.

Hey Andypiper
So do I need to upload my image between this ratio 300x157 - 4096x4096.
That’s it or do I need to change anything in the code part.
Also I want to ask you why in some blog post it’s taking default home page?

Is it when I update size image it’ll get sorted.

[andypiper]

Changing the image will help it to appear correctly in the right ratio in the image (after the cache clears in 5-7 days). If some pages are showing the home page card then I can only assume that those pages do not contain unique markup. You should be able to check that for yourself by viewing the page source.

[andypiper]

[poojajagga3]

Yes, I was the facing the same issue & won’t able to solve because of this I’ll have to remove the large cards.
Can you help me out?
