Display more lines on SharePoint news feed

Dear community,

I am quite new to SharePoint, and maybe I lack the right words to describe what I need solved. However, I am creating a news web part on a SharePoint homepage and I need more lines in the description display. 

I have found the following image in one of the Microsoft support sites: https://support.microsoft.com/en-us/office/use-the-news-web-part-on-a-sharepoint-page-c2dcee50-f5d7-434b-8cb9-a7feefd9f165?ns=spostandard&version=16&syslcid=1033&uilcid=1033&appver=spo160&helpid=wssenduser_usenewswebpart_fl852598&ui=en-us&rs=en-us&ad=us#bkmk_layouts Still, I haven't found how exactly to do this:

Here, there are 2 lines. Usually, in my news web part I only have 1 line. I would really appreciate your assistance!

Best regards,

Indie
