Simple four-step process
How the TV visualizer works
Get a practical preview using a photo of the wall where your TV will go.
Crop the image
Frame the wall area so the preview focuses on the space where the screen may be placed.
Set the scale
Mark two points with a known distance between them, such as a measured wall section or door width.
Compare TV sizes
Choose a diagonal size, move the preview on the wall and save an image to discuss or review later.
A quick starting point
What TV size suits your viewing distance?
Enter the distance from your usual seating position to the screen. Choose how immersive you want the experience to feel.

Popular TV size comparisons
Compare diagonal, width, height and screen area before deciding whether the larger screen is worth the extra space.
Plan the whole space
Room size to TV size: look beyond the floor area
Room dimensions are useful, but seating distance and the width of the TV wall are often more helpful when choosing a screen. Check all three before settling on a size.
- Enter room length and width.
- Check your seating distance.
- Compare the screen width with your available wall space.
Sit at a comfortable distance
How far should you sit from your TV?
Viewing distance changes how large the picture feels. Resolution, viewing angle and personal preference all influence what feels comfortable.
◉
Everyday viewing
A less immersive viewing angle can feel more relaxed for general television, news and longer sessions.
About 30° as a planning reference◎
Immersive viewing
A wider viewing angle can make films and games feel more cinematic, although some viewers prefer more distance.
About 40° as a planning reference▤
Resolution matters
Higher pixel density can make close viewing more practical, but it does not determine comfort on its own.
Consider 4K, Full HD and 8KWant a recommendation for your exact distance?

Plan the position, not just the size
How high should you mount your TV?
Screen centre, seated eye height, furniture and viewing angle all affect mounting position. Use the calculator to estimate the top, centre and bottom of the screen.

A few details can change the decision
What else should you consider?
Screen diagonal is only one part of choosing a TV. Think about the physical space, how you use the screen and the specifications of the exact model.
Will the TV fit your wall?
Compare the estimated screen width with the usable wall space. Leave room for the bezel, cables, ventilation and any side furniture.
Check room and wall fit →Screen size vs. TV dimensions
The diagonal describes the visible screen. The outer TV body may be wider and taller, and the stand adds depth and footprint.

Movies, gaming, sports and everyday viewing can lead to different preferences for screen size, distance and refresh rate.

Weight, VESA pattern, stand footprint, ports and refresh rate are model-specific. Confirm these details with the manufacturer before installation.

TV size questions, answered
Quick answers to help you choose a screen size and plan your setup.
What TV size is best for my room?
Start with the distance between your usual seating position and the screen. Then check the available wall width, room layout, resolution and your preferred viewing angle. Room floor area alone is not enough to determine the best size.
What TV size should I get for a 2-metre viewing distance?
For a 4K TV, a screen around 55–65 inches can be a useful starting range depending on whether you prefer relaxed or more immersive viewing. Use the viewing distance calculator to explore the assumptions and alternatives.
Is a 55-inch or 65-inch TV better?
A 65-inch screen has about 40% more visible screen area than a 55-inch 16:9 screen. Whether that is better depends on seating distance, available wall space, budget and personal preference. See the 55 vs. 65-inch comparison.
How do I calculate TV screen dimensions?
For a standard 16:9 screen, width and height can be estimated from the diagonal using the 16:9 aspect ratio. These figures describe the visible screen and exclude the bezel. Actual TV body dimensions vary by model.
How far should I sit from a 4K TV?
There is no single mandatory distance. Viewing-angle references around 30° for everyday viewing and 40° for a more immersive experience are useful starting points. Comfort and content preference matter too.
Does resolution affect viewing distance?
Yes. Higher resolution allows you to sit closer before individual pixels become noticeable, but viewing angle and comfort still influence the distance that feels right.
Can a TV be too big for a room?
A screen can feel overwhelming if you sit very close or need to move your eyes or head excessively to follow the picture. Check the viewing angle and try a visualization before buying.
How much wall space do I need for a 75-inch TV?
A 75-inch 16:9 screen is approximately 65.4 inches wide and 36.8 inches high. The actual television body is usually a little larger. Check the exact manufacturer's dimensions and allow clearance for mounting and cables.
How high should I mount my television?
A common starting point is to place the screen centre near seated eye level, then adjust for the seating position, screen size and viewing angle. Use the TV mounting height calculator for an estimate.
How do I visualize a TV on my wall?
Upload a photo of your wall, crop the area, mark two points with a known real-world distance and choose a TV size. The preview estimates the screen's size on the photo. Measure the actual space before buying.
Are screen dimensions the same as the actual TV dimensions?
No. Screen dimensions describe the visible display area. The TV's outer body includes the bezel and may be wider and taller. A stand can also add depth and width. Always check the specific model's specification sheet.
Measure. Compare. Visualize. Then choose.
