The jump from 40" to 50" is one of the most common TV upgrades people consider — and for good reason. The 50-inch screen delivers 56.3% more viewing area than the 40-inch, which means you're getting significantly more screen for your money. In physical terms, the 50" is 8.7 inches wider and 4.9 inches taller. That's not a subtle difference — it's immediately noticeable from across the room.
The 40-inch TV measures 34.86" wide × 19.61" tall (88.55 × 49.81 cm), with a total screen area of 683.68 square inches. The 50-inch TV measures 43.58" wide × 24.51" tall (110.69 × 62.26 cm), with a total screen area of 1068.25 square inches. That's a difference of 384.6 square inches — roughly 56.3% more screen.
For a 40-inch TV, you'll want to sit between 4 and 6.7 feet away (ideal: about 5.3 feet). For the 50-inch, the sweet spot is 5 to 8.3 feet (ideal: about 6.7 feet). If your couch is closer than 5 feet to the wall, the 50" might feel overwhelming — the 40" could actually be the better pick for your space.
A 40" TV works well in a bedroom, office, or small apartment living room. The 50" is better suited for a bedroom or medium-sized living room. Measure your actual viewing distance before deciding — the "right" size is the one that fits your room, not the biggest one that fits your budget.
If 50" feels like too big a jump, consider the 43" as a middle ground. See our comparisons: 40 vs 43" or 43 vs 50".
