What is a good audience size for Facebook ads?

[Achieve_Success]

I'm currently creating a Facebook ad but I'm not sure if i should target broad or narrow. I currently have an audience size of 200k. Do you think that's too little?

Also how many interests should I target per ad set?

Thanks

Hi! We are not gurus but we also had an experience with FB. We narrowed an audience by big cities. This way there is a higher chance to reach a target audience.
Good luck
