What is the format of today's headline video cover?

Clear+focus+fit theme, the official recommended size of the headline cover picture: 900 pixels X500 pixels.

The opening rate of an article is closely related not only to the title, but also to the picture on the cover. Therefore, attention should be paid to the selection of cover pictures: ① the picture has high definition; ② The background of the picture is clean and the key points are prominent; (3) The pictures should be consistent with the theme of the article. After collecting the wisdom of each family, an optimal size is summed up: 600 pixels X275 pixels. Recommended size of sub-cover picture: 200 pixels X200 pixels. The same is true of the second cover picture. Try to keep the aspect ratio of 1: 1. Otherwise, the pushed picture will not be displayed completely because it is compressed.
