there are 13 font types of Open Sans in the Adobe library (3 of them of the Condensed family):
... vs. (12 fonts in) Google:
But e.g. is the style "Regular" / "Regular 400" exactly the same (using it in print publications) and therefore does it not matter which one I use?
Thank you for reaching out and sorry for the delay in response. I have shared your question with our Fonts team so that I can give you the right information. The team is on vacation. Hence, please expect a delay in response.
I will make sure to get back to you as soon as I hear back from the team.
I really appreciate your patience.
Happy New Year in advance.
Thank you for your patience, mycc. Here is the answer to your question-
As to the discrepancy in the number of fonts listed (13 vs 12): we include the 3 “Condensed” in the main “Open Sans” family, while Google does not include those, and Google includes 2 “Medium” (upright & italic) that we do not include in our listing.
About whether our “Regular” is exactly the same as Google’s “Regular 400” —our team is investigating on this one if there is a discrepency.
