FAQ
What does TV size mean?
It is the diagonal length of the screen. A 65-inch TV has a 165 cm diagonal, which is about 56.9 × 32.0 inches (143.9 × 80.9 cm) at 16:9.
Do the dimensions include bezels?
No — figures here are screen-only. Full product width is typically 0.5–1 inch larger; check the manufacturer's spec sheet for exact mounting dimensions.
Is a bigger TV always better?
If you sit farther than 1.5× the screen height (4K), a larger size will still look sharp. Measure your couch distance and apply the rule above.
