In March 2022, Samsung rebranded the device as "Galaxy Fold 3" in certain Eastern European territories, potentially due to the Russian invasion of Ukraine and Russia's use of Z for military vehicles.

The Galaxy Z Fold 3 has two screens: its external cover screen which is a 6.23-inch 120 Hz display, and its foldable inner screen which is a 7.6-inch 120 Hz display featuring support for the S Pen Pro and the S Pen Fold Edition; both of which feature support for variable refresh rate to help maximize power efficiency.

While the inner display remained totally unchanged in its size and shape compared to the previous generation Z Fold 2, the external cover display was actually made ever so slightly wider by about +1 mm through a slight reduction in display bezel (making its aspect ratio ~24.5:9 vs the Fold 2's ~25:9), which as such also made it ever so slightly larger by about the same amount (~15.8 vs ~15.7 cm).
