How big is a 43-inch screen?

A 43-inch screen in the usual 16:9 shape has a lit picture 37.5 inches wide and 21.1 inches high (95.2 x 53.5 cm). The 43 inches (109.2 cm) is the diagonal, corner to corner. The frame around the picture adds to the outside size.

These are worked from the diagonal and the 16:9 shape, so they describe the lit picture only. A real panel can differ by a few millimetres, and the outside of the cabinet is larger by the width of its frame. Use the drawing of the exact model for a cut-out, a recess or a tight alcove. For the height on the wall, see how high to mount a 43-inch screen.

How far away can people read a 43-inch screen?

It depends on how much text you put on it. Fewer lines means bigger letters, and bigger letters read from farther away. Each distance below is the farthest point where that much text still fits at a letter height people can read.

We plan on 1 inch of capital letter height for every 30 feet of distance, the road-sign planning figure reported by Federal Highway Administration research, which assumes 20/40 vision. 20 feet per inch is the safer figure for fast reading. A line takes 1.7 times the capital height. For pictures and video our rule of thumb is 10 times the picture height, with 16 times as the limit. Thin fonts, weak contrast and glare all shorten these distances. To start from the distance instead, use the viewing distance calculator.

Area grows with the square of the diagonal, so a small step in inches is a bigger step in picture. See every size in one table.

Pixel size on a 43-inch screen

The same resolution spread over a bigger picture makes bigger pixels. From the distance in the last column, a person with normal eyesight no longer sees separate pixels.

Pixels blend where one pixel takes up about one arcminute of your vision. Whether a given model is HD, Full HD or 4K is on its own spec sheet.

Landscape screens, picture only. Every frame between two screens adds a gap, so the finished wall is a little larger than this. Add the frame width from the drawing for each join.

Other shapes with a 43-inch diagonal

The diagonal alone does not fix the width. A squarer screen with the same diagonal is narrower and taller, and it has more picture area.
