48 inch TV dimensions

The 48 inch is mostly an OLED size, and it is the one to look at if you want that kind of panel in a room that cannot take a 55. Its dimensions are what make it fit, so they are worth reading before the specification.

Which width do you mean?

• 106.3 cm is the picture, measured across the lit area. It comes from the 121.9 cm diagonal, and it is shared by every true 48 inch 16:9 set.
• About 107.5 cm is the set with its thin bezels, which is what a media unit, an alcove or a gap between cupboards has to hold.
• About 69.9 cm is the distance between the feet, and a stand has to be wider than that.

The 48 inches is measured along the diagonal of the picture, corner to corner, with the bezel left out. A set named by size class can come out a few millimetres under that, so if a spec sheet and this page differ by a centimetre, the spec sheet is right for that model.

48 inch TV size in cm, inches and feet

With the stand and without it

A 48 inch TV measures about 66.6 cm with its feet on: 61.6 cm of set and 5 cm of foot, or 26.2 in. The feet ask for a shelf about 25 cm deep and a stand wider than about 69.9 cm. Wall mounted, the feet go and the bracket adds a depth that differs by model.

The picture is 59.8 cm tall, about a third of the figure’s height, and 106.3 cm wide. On a wall it reads as a considered size, with a cabinet beneath it and space around it.

Set against the 48, the 43 inch is 10% narrower with 20% less picture, and the 50 inch is 4% wider with 9% more.

The 50 inch adds only 4.4 cm of picture width. The size that changes the room is the 55, and the two have their own pages: the 50 inch and the 43 inch.

48 inch against 55 inch

Compare any two screens

Seven inches of diagonal, 14.6% more, make a 55 inch 15.5 cm wider and 8.7 cm taller than the 48, with 31.3% more picture, which is a lot of picture for so small a step. The cost shows up as furniture: a 55 inch is about 123 cm across and does not fit a 120 cm unit. The 55 inch page has the tables for the size most rooms end up choosing between.

Will it fit?

On a 120 cm wide unit the set uses 90% of the top, with 6.3 cm clear each side, and on a 150 cm wide unit the margin is 21.3 cm. In a 140 cm × 90 cm alcove it takes 77% of the width with 16.3 cm each side. A 55 inch in the same alcove would leave under 9 cm each side, and a 65 inch would not go in.

Measure the opening, not the picture, and measure it at the height where the set will stand. A gap that is wide enough low down can be narrower at the top, where a cupboard door or a curtain pole sits.

How far to sit

Comfortable viewing distance for a 48 inch television, by what it is used for

Used for	Sit	In feet	Field of view
General TV	1.7 m – 2.1 m	5 ft 8 in – 7 ft 0 in	28–34°
Sports	1.6 m – 2 m	5 ft 4 in – 6 ft 6 in	30–36°
Gaming	1.5 m – 2 m	5 ft 1 in – 6 ft 6 in	30–38°
Movies	1.5 m – 1.7 m	4 ft 9 in – 5 ft 8 in	34–40°
Home cinema	1.3 m – 1.6 m	4 ft 3 in – 5 ft 4 in	36–45°

A 48 inch TV fills 28° to 34° of your view from 1.7 m to 2.1 m, which is the everyday range, and 34° to 40° from 1.5 m to 1.7 m, which is the range for films. For reference, the SMPTE figure is usually quoted as a 30 degree view and the THX figure as 40.

That is a small living room or a large bedroom. At 2.5 m the set looks small, and the 55 inch is the step to consider. The 8 foot seat guide shows what the next sizes look like from further back.

Used on a desk

Some buyers put a 48 inch on a desk as a very large monitor. For ordinary desk work the calculator puts the seat 100 cm to 138 cm from the screen, which is further than most desks are deep. At 80 cm the picture spans about 67° of your view and at 70 cm about 74°, so you turn your head to see the corners. If you plan to use it that way, give it a deep desk, or mount it on the wall behind. The guide to what size monitor you need puts a number on the distance for each size.

Is 4K worth it on a 48 inch?

A 4K panel at 48 inches packs 92 pixels per inch, and a 1080p one 46. By the 20/20 convention of 60 pixels per degree, 4K stops showing single pixels from about 1 m and 1080p from 1.9 m. A living-room seat 1.7 m to 2.1 m away is past the limit for 4K and right at it for 1080p, so 4K is the resolution to look for, and it matters most if the set will be used on a desk.

The 60 is a convention, not a limit. A 2025 paper in Nature Communications measured a mean of about 94 pixels per degree for fine black and white detail, so a sharp-eyed person can pick out more than the convention allows. On a desk at 70 cm, 4K gives only about 44 pixels per degree, short of both figures, which is the real reason to sit back at a metre or more.

Mounting and stands

The mounting holes on the back follow the VESA standard, quoted in millimetres, and the pattern depends on the model. Read it from the spec sheet and check it against the bracket, because a mount that fits a 48 inch of one make may not fit another. On a stand, the feet are about 69.9 cm apart, so the unit has to be at least that wide and the set overhangs it at both ends.

Who a 48 inch suits

A 48 inch suits a living room that is a little small for a 55, a bedroom with a seat 2 m away, or a desk that has been given a large screen. At 107.5 cm across it fits a 120 cm wide unit and a 140 cm × 90 cm alcove, which is where the bigger sizes begin to struggle.

It is the wrong size for a room where the sofa is 3 m back. The TV size guide for a bedroom and the 12 by 12 foot room guide work through two rooms of this kind.
