How big is a 70 inch TV with the frame and stand?
The 70 inch figure covers the glass only. Frames, stands and depth vary by model, and they decide whether a TV fits your wall. Here are the real measurements of popular 70 inch TVs, from each maker's spec sheet.
Each model name links to its maker's spec sheet. Prices open on Amazon (affiliate links).
What did the real models show?
The table lists three 70 inch TVs from Vizio and Samsung. Their bodies are 61.7 in156.7 cm to 61.8 in157.1 cm wide, or 0.7 in1.8 cm to 0.8 in2.1 cm more than the screen itself. With under 1 in (2.5 cm) between them, the frame rarely decides whether one of these fits.
Without its stand, the Samsung UN70U8000HFXZA and Vizio VQD70R-1001 are the thinnest at 3.0 in7.7 cm deep. At the other end, the Vizio V4K70M-0801 is 3.5 in8.9 cm deep.
Weights run from 40.96 lb18.6 kg for the Vizio VQD70R-1001 to 49.58 lb22.5 kg for the Vizio V4K70M-0801. A mount rated for 50 lb22.7 kg or more covers the weight of every model here.
On their stands, they sit 2.0 in5.1 cm to 2.8 in7.1 cm taller, which matters under a shelf or a window. Vizio does not list a stand width for the V4K70M-0801 and VQD70R-1001.
They use two VESA patterns, from 300 x 300 to 400 x 300 mm. The most common is 300 x 300 mm, on two of them, but check your exact model before you buy a mount.

How far to sit from a 70 inch TV
Sit 7.0 ft2.1 m to 9.5 ft2.9 m away. At that distance the screen fills 30 to 40 degrees of your view, the range film and TV engineers recommend.
It feels too close at 5.0 ft1.5 m, immersive at 6.0 ft1.8 m, ideal at 8.0 ft2.4 m and relaxed at 10.0 ft3.0 m to 12.0 ft3.7 m. Not sure of your distance? Use the TV size calculator to work backwards from your seat.
Is 4K worth it on a 70 inch TV?
It depends on where you sit. With 20/20 vision you stop seeing pixels beyond a certain distance. On a 70 inch screen that is 9.1 ft2.8 m for 1080p and 4.6 ft1.4 m for 4K.
Sitting closer than 9.1 ft (2.8 m)? 4K will look clearly sharper than 1080p on a 70 inch screen.
How does a 70 inch TV compare with other sizes?
Going up to 75 inches adds 15% more screen area and 4.4 in11.1 cm of width, and dropping to 65 inches loses 14% and 4.4 in11.1 cm. Area grows with the square of the diagonal, so a few inches feel bigger than they sound. Either way, that is a clear step.

How we measure
Screen width = diagonal x a / sqrt(a^2 + b^2) and height = diagonal x b / sqrt(a^2 + b^2) for an a:b screen. Viewing angle = 2 x arctan(half the screen width / distance). Pixel visibility uses 1 arcminute, the limit of 20/20 vision.
