Dimensions of 55-inch TVs—width, height, and depth by model
How wide is a 55-inch TV? 139.7 cm diagonally, about 123 cm in actual width. A table of measurements by model—with and without the stand, including VESA standards—and what to measure before mounting or buying a TV stand.
The short answer: About 123 cm wide
55 inches is the diagonal: 55 × 2.54 = 139.7 cm. With a 16:9 aspect ratio, the panel itself is 121.8 cm wide and 68.5 cm high—a geometric calculation that does not depend on the manufacturer. The bezel adds a little: among the seven 55-inch models for which the body dimensions were published, the width ranges from 122.5 to 123.7 cm and the height from 70.6 to 71.7 cm.
The difference between the narrow and wide models is 1.2 cm, meaning the brand makes almost no change to the width. What does make a difference, however, is the size: going from 55 to 65 inches adds 22.1 cm to the panel’s width and 12.4 cm to its height. That’s the difference between a TV that fits into a 125-centimeter niche and one that doesn’t.
Depth: The TV is thin, but the stand isn't
The unit itself is 4.6 to 7.7 cm deep in the models measured. With the stand, the depth increases to 19.9 to 29.7 cm, and for this sideboard, that’s the determining factor. A 30-cm-deep sideboard will accommodate all eight models for which a depth with the stand is listed; a 25-cm-deep sideboard will accommodate only three of them.
The stand raises the TV by 5.1 to 6.7 cm, so the total height with the stand is 75.9 to 78.4 cm. If there is a shelf above the cabinet, measure based on the height with the stand rather than the height of the TV.
VESA Standard: Three standards of the same size
Among the six 55-inch models for which mounting standards are listed, three different standards appear: 200×200, 300×200, and 300×300 mm. A mounting arm purchased in advance “for a 55-inch model” may not fit the model you choose.
The correct procedure: Choose a model, check its VESA standard in the table or spec sheet, and only then buy a mount. The TV’s weight is a separate parameter that the mount must support.

What to Measure at Home Before Ordering
Niche or cabinet width: For a closed niche, 125 cm is sufficient for all models in the table; for open placement, a more generous space is recommended for ventilation and cables. The depth of the cabinet versus the depth of the model’s stand. The height to the shelf above versus the height including the stand. And if mounting on the wall—the location of the outlet and the communication port, which should be behind the TV.
The center of the TV is about 35 cm above the bottom edge of the unit, and this measurement helps you position the outlet so that it is out of sight. Here’s a simple way to get a sense of the size: Stick a piece of tape measuring 123 × 71 cm on the wall.
55 or 65?
This decision is usually made based on wall space rather than in the store. If the available width is 125–140 cm, 55 inches is the largest size that will fit; a 65-inch model starts at 144.1 cm in our catalog. If there is 150 cm or more, both sizes will fit, and the decision comes down to viewing distance and personal preference.
In a bedroom or small living room, where the distance from the sofa to the wall is short, a 55-inch TV is a common choice. It’s a good idea to view both sizes in the store from a distance similar to that in your home before deciding based on the number.
Frequently asked questions
How wide is a 55-inch TV?
The panel itself measures 121.8 cm (55 inches diagonally at a 16:9 aspect ratio). Including the frame, the 55-inch models listed in our catalog range from 122.5 to 123.7 cm. When planning a niche, it’s best to allow for 124 cm and add some extra space.
How many centimeters is 55 inches?
139.7 cm diagonally (55 × 2.54). This is not the width: the width of a 16:9 TV of this size is 121.8 cm, and the height is 68.5 cm.
How tall is a 55-inch TV with a stand?
Without the stand: 70.6–71.7 cm; with the stand: 75.9–78.4 cm for models for which dimensions are listed. The stand adds 5.1 to 6.7 cm.
What depth of TV stand do I need for a 55-inch TV?
The depth of the base in the models measured ranges from 19.9 to 29.7 cm. A 30-cm-deep sideboard fits all of them; a 25-cm-deep one fits only three out of eight. Check the table for the specific model.
Where do the measurements in the table come from?
From the manufacturer’s or importer’s specification sheet, as it appears in the product listing in the store’s catalog. Models for which exact dimensions have not been published do not appear in the table. Before installing or ordering custom cabinetry, it is advisable to verify the dimensions against the final model.
