A 43-inch TV has a substantially larger screen than a 40-inch model, but the better choice depends on your viewing distance, room layout, budget and how immersive you want the picture to feel.
These figures describe the visible screen for a standard 16:9 aspect ratio. Actual TV body dimensions vary by model.
88.6 × 49.8 cm
95.2 × 53.5 cm
| Feature | 40-inch TV | 43-inch TV |
|---|---|---|
| Diagonal | 40 in / 101.6 cm | 43 in / 109.2 cm |
| Screen width | 47.9 in / 88.6 cm | 37.5 in / 95.2 cm |
| Screen height | 19.6 in / 49.8 cm | 21.1 in / 53.5 cm |
| Relative screen area | Baseline | About 16% larger |
| Full TV dimensions | Model-specific | Model-specific |
| Weight and VESA | Model-specific | Model-specific |
Compare the main measurements and planning figures for both screen sizes. Screen dimensions are calculated for a 16:9 display; room and viewing figures are practical estimates rather than guarantees.

Room area is a broad planning reference, not a minimum requirement. Actual TV weight depends on the model and whether the stand is attached.

This proportional illustration shows how a 40-inch screen compares with a 43-inch screen, alongside a human-height reference. The smaller outline is nested inside the larger screen to make the increase in width and height easier to understand.
The illustration is a visual aid, not a room-fit measurement. Actual product dimensions include bezels and may differ slightly by model.
A typical 40-inch 16:9 screen is approximately 34.9 inches wide and 19.6 inches high (88.6 × 49.8 cm), excluding bezels. Check the exact model for overall width, height, depth, stand footprint, weight, resolution, refresh rate and VESA pattern.
A typical 43-inch 16:9 screen is approximately 37.5 inches wide and 21.1 inches high (95.2 × 53.5 cm), excluding bezels. The TV body and stand add to these dimensions and vary by manufacturer and model.
The 43-inch screen is approximately 8.7 inches (22.1 cm) wider and 4.9 inches (12.4 cm) taller than the 40-inch screen.
Because both width and height increase, the 43-inch 16:9 screen has approximately 16% more visible area than the 40-inch screen.
Allow additional clearance for the bezel, cabinet, stand, cables and ventilation. Use exact model dimensions when checking wall or furniture fit.
Viewing distance is influenced by resolution, viewing angle, eyesight and personal comfort. The following are illustrative starting points rather than universal standards.
If your seating is relatively close, a 40-inch TV may feel more comfortable. If you sit farther away and want a larger viewing angle, 43 inches may be more appealing. Try both settings in the viewing-distance calculator.
Calculate viewing distanceRoom area by itself is not enough to decide. Measure the seating-to-screen distance, available wall width, viewing angle and furniture layout.

A 43-inch screen can feel more immersive when seating distance and room layout support it.
A larger image can be easier to follow from farther away. Broadcast resolution and motion handling also matter.
Compare input lag, refresh rate, response time, HDMI features and seating distance in addition to screen size.
Both can work well. Choose based on the room, viewing habits and how prominent you want the screen to feel.
Value depends on the actual models and their prices, not just screen diagonal. Compare display technology, brightness, HDR performance, refresh rate, warranty, operating system and connectivity.
A lower price per square inch can be one comparison point, but it should not outweigh picture quality, reliability or features you will actually use.

Compare both screen sizes against the same room photo and wall calibration. A visualizer is an estimate; confirm the final placement with physical measurements.
A standard 16:9 43-inch screen has approximately 16% more visible screen area than a 40-inch screen.
Not automatically. Check seating distance, wall width, viewing angle and furniture layout before deciding.
It can be worthwhile if you want a more immersive screen and have enough space. Compare the actual models and prices too.
Around 5.0 metres can be used as an everyday starting estimate, but adjust for resolution and personal comfort.
Around 2.5 metres can be used as an everyday starting estimate, with closer viewing possible depending on resolution and preference.
Most modern TVs use a 16:9 aspect ratio, but check the specifications for the exact model.
Choose 40 inches when room fit, closer seating or budget matters most. Choose 43 inches when you have the space and want a larger, more immersive image. Before buying, compare exact model dimensions, features, price and mounting requirements.
