What size ring light is best for streaming?

For streaming and video calls, an 18 inch ring light is the standard it provides even, wraparound illumination and creates the signature catchlight ring in your eyes. A 12 inch light works for close up content and smaller spaces but may not evenly light your full face and upper body. 10 inch and smaller ring lights are best for phone only content and selfies. If your primary use is streaming at a desk, 18 inches is the right size.
