How do you lay out uv’s symmetrically?

I’m trying advance my uv editing and texturing to sell commercial models. I really want to know how people layout their uvs like this?

I can do it manually, but it’s never perfectly symmetrical. I often see commercial models/avatars their uvs are clean and symmetrical. How can I achieve this?

This screenshot if from Ocuuda’s work on twitter.

I reached out to the artist, but I’m not familiar with twitter, so I’m not sure if they’ll see my message or will feel comfortable answering my questions
