Hi,
Does anybody know what this source is? They use it on the national geographic web page in the images

I checked the source code of the website.
Looks like a special NatGeo font called Geo Brand Bold.
Maybe try https://www.myfonts.com/collections/verdana-font-microsoft-corporation

Thansks Robbo!

yes, I looked at the source code of the web, which is used by open sans and others, but it is not the same as the one used in the images

In the natgeo account, Pinterest uses that typography for all the images... The V ends in a point
