Completeness-corrected companion fraction per 0.5 dex bins in projected separation for small and large TESS planet candidate hosts observed in this survey. For reference, the separation distribution of field binaries from Raghavan et al. (2010) is included. Both populations of TESS planet hosts have suppressed rates of close binaries but diverging binary rates at wide projected separations. Large planets (Rp > 9 R⊕) are approximately 3.5× more likely to be found in a wide binary, compared to field stars. Conversely, small planets are 2× less likely to be found in a wide binary.
