Hey there
Do you mean your blog section? all your other section images are the same size,
For blog images it’s better to use resized images, otherwise they are getting stretched and not suitable for viewing
Where can i find the documentation where i can know the recommend size for each section? Like for the banner, product size etc?
There is no such documentation because its rally depends on you, you may use any size images but if you want to have unified sizes just use images with the same size
