How they differ

The 43-inch 16:9 panel is 95.2 cm (37.5 inches)37.5 inches (95.2 cm) wide and 53.5 cm (21.1 inches)21.1 inches (53.5 cm) tall.

That extra 15.5 cm (6.1 in)6.1 in (15.5 cm) of width matters on a narrow wall or a tight TV spot. At 1.8 m (6 ft)6 ft (1.8 m), the 43-inch fills 29 degrees of your view and the 50-inch fills 34. The 30-degree SMPTE seat is 1.8 m (5.8 ft)5.8 ft (1.8 m) back for the 43-inch and 2.1 m (6.8 ft)6.8 ft (2.1 m) for the 50-inch. The 40-degree THX seat is 1.3 m (4.3 ft)4.3 ft (1.3 m) and 1.5 m (5.0 ft)5.0 ft (1.5 m). Both are 4K, at 102 and 88 PPI. At 1.8 m (6 ft)6 ft (1.8 m) each one is past its Retina distance, which is 0.9 m (2.8 ft)2.8 ft (0.9 m) for the 43-inch and 1.0 m (3.3 ft)3.3 ft (1.0 m) for the 50, so single pixels won't show from the bed.

Verdict

A bedroom usually gives you one wall and one seat, so measure both first. If the wall can't take 110.7 cm (43.6 inches)43.6 inches (110.7 cm) across, the 43-inch is the answer. If it can and your seat is far enough back, the 50 gives more picture without leaving the 30-degree guideline.
