Most current MF cameras/digital backs have a 44x33mm (Hasselblad H6D 50C, Leica SL, Pentax 645, Hasselblad X1D, Phase One 50MP Mamyia Leaf Credo 50) or 43.8x32.9mm (Fuji GFX 50S, Mamiya Leaf Credo 40mp) sensor.
The current 100mp Hasselblad and 100mp and 80mp and 60mp achromatic Phase One digital back sensors have a 53.7x40.3 or 40.2mm sensor.
The reason for the smaller sizes is manufacturer (Sony for instance) based, and cost based. The bigger sensors are very expensive in comparison.
That is also a reason why MF digital sensors have always come without a AA-filter, AA-filters are very expensive to produce and the small quantities and large sizes prevented MF cameras to have them.
