Comments by "LoneTech" (@0LoneTech) on "What might the new Webb telescope discover?" video.
At 3:32 an image is shown of the primary mirror sizes of Webb and Hubble telescopes, while what's stated is about field of view. The mirror or aperture size affects light gathering efficiency and available resolution, not field of view, which is at the other end - a conceptual area on the celestial sphere. Checking NASA's overview comparison, the >15x factor is indeed field of view, while the mirror area factor is more like 6.25x. Both telescopes have a variety of instruments with distinct fields of view (some of which aren't even contiguous).
