At 35% more screen area, the 50 inch is a meaningful step up from the 43 inch — not a subtle upgrade. The 15.5 cm width difference is visible in any room, and the picture will feel noticeably larger at any viewing distance.
Choose the 43 inch if: the TV is going in a bedroom where the viewing distance is consistently under 2.0 m, the room or furniture has limited width and cannot comfortably fit a 110+ cm screen, or you want a compact TV for a kitchen, guest room, or secondary room where size is less important than fit. The 43 inch is well-suited to any space where you sit within arm's length of the screen — it fills the field of view well at 1.5–2.0 m.
Choose the 50 inch if: the viewing distance is 2.0 m or more and you want the TV to serve as a primary screen — for a living room, a larger bedroom, or a study. At 2.0–2.5 m the 50 inch gives a substantially more engaging picture than the 43 inch, and both sizes remain practical enough for furniture placement. The 50 inch is also worth considering as a bedroom TV in larger master bedrooms where the bed is 2.5–3.0 m from the screen.
Bedroom rule of thumb: If the foot of the bed is under 2.0 m from the TV wall, the 43 inch is the better fit. If it is 2.0–3.0 m, the 50 inch gives a more satisfying picture. Beyond 3.0 m, consider stepping up to a 55 inch.

A 50 inch TV has 35% more screen area than a 43 inch TV. The diagonal increases by 7 inches (17.8 cm), the width from 95.2 cm to 110.7 cm (a 15.5 cm increase), and the height from 53.5 cm to 62.3 cm. This is one of the larger size steps in the mainstream TV range — significantly more noticeable than, say, the step from 50 to 55 inches (21% area). In a room at a typical 2.0 m viewing distance, switching from 43 to 50 inches will feel like a substantial upgrade.
The decision is largely about room size and viewing distance. For a bedroom where the bed is under 2.0 m from the screen, the 43 inch is the more comfortable and proportionate choice — the 50 inch at close range fills more of your visual field than is ideal for extended viewing. For a small living room, a study, or a bedroom with a longer viewing distance of 2.0–3.0 m, the 50 inch gives a noticeably more satisfying picture and is the better long-term investment. Both are compact TVs by today's standards; neither will feel outsized in a normally proportioned room.
A 43 inch TV is recommended for viewing distances of 1.6 m to 2.7 m (based on 1.5× to 2.5× the 109.2 cm diagonal). A 50 inch TV is recommended for 1.9 m to 3.2 m. For 4K content, you can comfortably sit at the minimum distance for each size. For HD content, aim for the middle of the range. If your room has a fixed sofa position of around 2.0 m from the screen, both sizes are in their comfortable zone — but the 50 inch will feel more immersive and give better value for a primary living room setup.
A 43 inch TV is an excellent bedroom size for most layouts. At 95.2 cm wide it sits comfortably on standard bedroom furniture and does not dominate the room. For a typical bedroom where the viewing distance from the bed is 1.5–2.5 m, the 43 inch is well within its comfortable range and gives a sharp, well-proportioned picture. If you have a larger master bedroom where the bed is more than 2.5 m from the screen, a 50 inch would give a more satisfying picture — the 43 inch starts to feel slightly small at that distance. For a guest room, children's room, or compact bedroom, 43 inches is the practical first choice.
