40" vs 43" Inch TV
Size Comparison

The jump from 40" to 43" is one of the most common TV upgrades people consider — and for good reason. The 43-inch screen delivers 15.6% more viewing area than the 40-inch, which means you're getting significantly more screen for your money. In physical terms, the 43" is 2.6 inches wider and 1.5 inches taller. That's not a subtle difference — it's immediately noticeable from across the room.

Exact Measurements

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 43-inch TV measures 37.48" wide × 21.08" tall (95.19 × 53.55 cm), with a total screen area of 790.08 square inches. That's a difference of 106.4 square inches — roughly 15.6% more screen.

Recommended Viewing Distance

For a 40-inch TV, you'll want to sit between 4 and 6.7 feet away (ideal: about 5.3 feet). For the 43-inch, the sweet spot is 4.3 to 7.2 feet (ideal: about 5.7 feet). If your couch is closer than 4.3 feet to the wall, the 43" might feel overwhelming — the 40" could actually be the better pick for your space.

Room Size

A 40" TV works well in a bedroom, office, or small apartment living room. The 43" is better suited for a bedroom, office, or small apartment 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.
