A 43-inch 16:9 TV measures 95.2 cm (37.48 inches)37.48 inches (95.2 cm) wide by 53.5 cm (21.08 inches)21.08 inches (53.5 cm) tall, with about 5097 cm² (790 square inches)790 square inches (5097 cm²) of screen. That's small enough for a bedroom dresser, a kitchen corner or a dorm room. It also works as a desk screen, though sitting close changes how the picture looks.

How this is calculated

A TV's size is its diagonal, measured corner to corner across the picture. A 43-inch screen is 109.2 cm on the diagonal, and the 16:9 shape splits that into 95.2 cm across and 53.5 cm up. In a small room the width decides whether the set fits the shelf or the wall gap. The seat distance decides how much of your view it fills, and a desk puts you close. From a desk 0.7 m (2.3 ft)2.3 ft (0.7 m) away, the screen fills about 67.6 degrees of your view, wider than the 40 degree THX reference.

Verdict

Pick 43 inches for a bedroom, kitchen, dorm or small room where a larger set would crowd the space. The panel measures 95.2 cm (37.48 in)37.48 in (95.2 cm) by 53.5 cm (21.08 in)21.08 in (53.5 cm), about 5097 cm² (790 in²)790 in² (5097 cm²) of picture.

As a desk screen it works, with a catch. At 4K the panel gives 102 PPI. That's less than the 109 PPI of a 27-inch 1440p monitor, so small text looks softer than on a desk monitor. Buy it for the desk when you want a wide, big picture more than sharp small text.

Frequently asked questions

How far should I sit from a 43-inch TV?
For a 40 degree view, sit 1.3 m (4.3 ft)4.3 ft (1.3 m) away. For a 30 degree view, sit 1.8 m (5.8 ft)5.8 ft (1.8 m) away. These are viewing angles, not hard limits. A bed or stool closer than the 40 degree seat fills more of your view, which suits a small room.
Is a 43-inch TV too small for a living room?
It can work in a small living room with the seat within about 1.8 m (5.8 ft)5.8 ft (1.8 m) of the screen. A sofa farther back needs a bigger set. A 55-inch gives the same 30 degree view from 2.3 m (7.5 ft)7.5 ft (2.3 m) away, so check the seat distance before you settle on 43.
Can I use a 43-inch TV as a desk monitor?
Yes, with a few trade-offs. The desk has to be deep enough for the TV's feet and for a seat distance you can live with. From 85 cm (34 inches)34 inches (85 cm) away or farther, single 4K pixels blend together. At a desk 0.7 m (2.3 ft)2.3 ft (0.7 m) away, you're closer than that, so single pixels can show.
What TV stand or console width do I need for a 43-inch TV?
Use the TV's full width from its spec sheet, not the screen width. The screen alone is 37.5 inches across. The frame adds a little to that. Choose a stand or console at least as wide as the whole TV so the set sits fully on top.
