Worked out by code, not stated by a source

Read from the lens name: each maker marks the sensor size a lens covers (Sony FE/E, Canon RF/RF-S, Nikon DX, Tamron Di III/Di III-A, Sigma DG/DC); every Fujifilm X lens is APS-C and every Micro Four Thirds lens is Four Thirds.

Each value is checked automatically against the source it links, on the date shown. How we build these pages

† The makers' own tables, row by row, with labels in our plain words (translated where the maker's page isn't in English); each row's numbers are checked against the page it links.
