The number of followers you need on Instagram to get paid varies depending on a range of factors, including your niche, engagement statistics, and the type of brand partnerships you pursue. However, as a general rule of thumb, most brands tend to look for influencers with at least 5,000 to 10,000 followers.
That being said, having a large following does not guarantee that you will get paid partnerships and that these partnerships will be lucrative. Brands are increasingly focused on engagement rates and authenticity, which means that influencers with a smaller but highly engaged following may also be attractive partners.
