Short answer
A TV’s size is its screen’s diagonal. For the standard 16:9 shape, the screen is 0.87 × the diagonal wide and 0.49 × the diagonal tall: a 55-inch screen is 47.9 in × 27 in, a 65-inch 56.7 in × 31.9 in, a 75-inch 65.4 in × 36.8 in and an 85-inch 74.1 in × 41.7 in. Current TVs add only 0.1–0.6 in of frame per side, so the whole TV is barely bigger than the screen.
Key takeaways
- Width ≈ diagonal × 0.87; height ≈ diagonal × 0.49 (16:9 screens).
- Going up one size class (55 → 65 → 75 → 85) adds about 9 in of width and 5 in of height each time.
- For wall space, use the whole TV’s measured width from the spec sheet; for furniture, check the stand’s width and depth too: they vary far more than the screen.
Use this page in two steps: the chart gives the screen size of every common TV size, and the size pages give measured dimensions of real, current models, including the parts that differ between brands (the stand, depth and weight).

The left columns are pure geometry: they’re the same for every 16:9 TV. The right column shows the range of whole-TV widths among the current models in our catalogue (blank where we don’t list models of that size yet).
Measured dimensions by size
For each popular size we list every current model we’ve checked, with width, height and depth with and without the stand, stand width, weight and VESA pattern, all from the manufacturers’ US spec sheets:

Why “65 inches” isn’t the width
TV sizes are diagonal measurements, a habit inherited from round picture tubes. Two consequences:
- The width is smaller than the size. A 16:9 screen is 87% as wide as its diagonal, so a 65-inch TV is about 57 inches wide.
- Area grows faster than the number. Area scales with the square of the diagonal: a 75-inch screen has 33% more picture than a 65-inch, and an 85-inch 71% more.
The size is also a rounded “class”. Spec sheets give the measured diagonal: Samsung, Sony, TCL and Hisense 65-inch sets measure 64.5 inches; LG’s 65-inch OLEDs measure 65.1. LG and Samsung also sell OLEDs in 77- and 83-inch sizes instead of 75 and 85.
How to measure your space
- Wall: measure the clear width between obstacles (corners, windows, doors, outlets you need to reach). Leave a few inches on each side; a TV pushed into a corner is hard to adjust and to service.
- Furniture: measure the top’s width and depth. Compare the depth with the TV’s “depth with stand”, and the width with its stand or feet span, not just the TV’s width.
- Height: if the TV sits under a shelf or a window, compare with “height with stand”.
- Seating: measure from where your eyes will be to where the screen will be. That decides the size more than the wall does: see the viewing distance calculator.
- Doorways and stairs: the box is much larger than the TV, about 8 in wider and 6 in taller.
The fastest sanity check is still painter’s tape: mark the TV’s outline on the wall and look at it from your seat.
Frequently asked questions
How do you measure a TV's size?
Measure the screen diagonally, from one corner of the picture area to the opposite corner, without the frame. That figure (rounded) is the size class: “65-inch” TVs from most brands actually measure 64.5 in.
How do you calculate a TV's width from its size?
For a 16:9 TV, multiply the diagonal by 0.872 for the screen width and by 0.490 for the height. A 65-inch screen is 65 × 0.872 = 56.7 in wide and 65 × 0.490 = 31.9 in tall. Add the frame (usually under half an inch per side) for the whole TV.
What size TV fits a 60-inch-wide space?
A 65-inch TV: current 65-inch models are 56.5–57.4 in wide. A 75-inch needs about 66 in.
Are all TVs of the same size the same width?
Nearly. Across the 18 current 65-inch models we list, the width varies by under an inch (56.5–57.4 in). What differs is depth (1–3 in), the stand (a 13.5-inch pedestal or feet 47 in apart) and weight (36.6–59.7 lb).
What are TV dimensions in centimeters?
Multiply inches by 2.54. A 55-inch screen is 122 cm × 68 cm; 65-inch 144 cm × 81 cm; 75-inch 166 cm × 93 cm; 85-inch 188 cm × 106 cm. The chart above lists every size.
