58 inch TV dimensions

The 58 inch is an in-between size, and nearly everything about choosing one comes back to the two sizes it sits between. It is a little wider than a 55 and a good deal narrower than a 65, and the space that rules out the second is often what makes it the right answer.

Which width do you mean?

Three widths get quoted for a 58 inch. The picture is 128.4 cm, which follows from the 147.3 cm diagonal and the 16:9 shape. The whole set is about 129.6 cm with its bezels, and that is the number to measure an alcove, a media unit or a gap between two cupboards against. The feet are about 103.7 cm apart, and a stand has to be wide enough to carry them.

Not every range is made at 58 inches, so check that the model you want comes in it before you plan the room around the size. If a spec sheet differs from this page by a centimetre or so, the spec sheet is right for that model.

58 inch TV size in cm, inches and feet

With the stand and without it

With the feet fitted a 58 inch TV is about 79 cm, made up of 74 cm of set and about 5 cm of foot. The feet are about 103.7 cm apart and ask for a shelf about 25 cm deep. Wall mounted, the feet go and a bracket takes their place.

The picture is 72.2 cm tall, which is about 40% of the figure’s height, and 128.4 cm across. On an open wall it still reads as a moderate screen; in an alcove it looks as if the space was made for it.

Between the 55 and the 65

Against the 58, the 55 inch is 5% narrower with 10% less picture, and the 60 inch is 3% wider with 7% more.

The 58 is 6.6 cm wider than a 55 inch, which is 3.3 cm each side, and 15.5 cm narrower than a 65 inch, with about a fifth less picture. That is why it works as the size for a space that is a little too tight for the 65.

58 inch against 65 inch

Compare any two screens

The 65 inch sits 15.5 cm wider and 8.7 cm taller on the wall, and its diagonal, 12.1% longer, brings 25.6% more picture, a bigger step than seven inches sounds. The 65 does not go in a 140 cm alcove and the 58 does. The 55 against 65 write-up covers the two sizes on either side of this one.

Will it fit?

In a 140 cm × 90 cm alcove the set uses 93% of the width and leaves 5.2 cm each side, which is tight and works. A 150 cm wide unit leaves 10.2 cm each side and a 180 cm wide one 25.2 cm.

On a 120 cm wide unit it overhangs. The body is wider than the top by 4.8 cm at each end, and the table counts it as fitting because the feet stand inside the unit, but it looks cramped. A wall mount avoids the question.

How far to sit

Comfortable viewing distance for a 58 inch television, by what it is used for

Used for	Sit	In feet	Field of view
General TV	2.1 m – 2.6 m	6 ft 11 in – 8 ft 5 in	28–34°
Sports	2 m – 2.4 m	6 ft 6 in – 7 ft 10 in	30–36°
Gaming	1.9 m – 2.4 m	6 ft 1 in – 7 ft 10 in	30–38°
Movies	1.8 m – 2.1 m	5 ft 9 in – 6 ft 11 in	34–40°
Home cinema	1.5 m – 2 m	5 ft 1 in – 6 ft 6 in	36–45°

Everyday viewing puts the seat 2.1 m to 2.6 m from a 58 inch TV, with the picture across 28° to 34° of your view, and films 1.8 m to 2.1 m, across 34° to 40°. The usual SMPTE and THX figures are 30 and 40 degrees. That is a very ordinary living room.

Ours is in a bedroom

Our own 58 inch hangs high on a bedroom wall with the pillow 2 m away, inside the calculator’s band for films, and from there it spans 35.6° of our view. At that distance 4K is more detail than an eye can pick out: a 1440p picture already gives 69.6 pixels per degree. The bedroom guide has the rest, including what a dark room shows up.

Is 4K worth it on a 58 inch?

A 4K panel at 58 inches packs 76 pixels per inch, and a 1080p one 38. By the 20/20 convention of 60 pixels per degree, single pixels stop showing from about 1.1 m at 4K and from 2.3 m at 1080p. From a seat 2.1 m to 2.6 m away, 4K is well past the limit and 1080p is right at it, which is the case for 4K at this size: finer text and cleaner edges.

The figure to treat with care is the 60. A 2025 paper in Nature Communications measured a mean of about 94 pixels per degree for fine detail. At our 2 m a 4K picture gives about 104 pixels per degree, above that mean, so on a wall 2 m from a pillow more pixels would buy very little.

Mounting on a wall

A bracket has to match the threaded holes on the back of the set. Those follow the VESA mounting standard and differ between models, so take the pattern from the manual and not from the size. A bedroom mount sits higher than a living-room one, because sitting up in bed puts your eyes above where they would be on a sofa. How high to mount a TV has the working for both.

Who a 58 inch suits

A 58 inch suits a space that cannot take a 65: a 140 cm alcove, a bedroom wall with a seat two metres away, or a 130 cm to 150 cm unit. From 2.1 m to 2.6 m it fills a comfortable share of the view, and at 129.6 cm across it is the largest of the common sizes that clears the alcove.

If the room is large and the seat is far back, you are paying for a size that looks small from there. If the choice is between 55 and 58 on size alone, take whichever the right model comes in. What size TV do I need works from the room.
