Choosing a new TV can be exciting, but with so many options available, particularly when it comes to size, it can quickly become overwhelming. While the allure of the biggest screen might be strong, the science of viewing actually dictates that optimal TV size is less about extremes and more about finding the right balance for your space and viewing habits. This guide will delve into the key factors to consider when comparing TV sizes, ensuring you make an informed decision and achieve the best possible viewing experience.
Understanding Field of View and TV Size

The core concept behind selecting the right TV size is field of view. Imagine your TV screen occupying a portion of your vision. If the TV is too small or too far away, it only fills a narrow field of view. The image on the left illustrates this: a 43-inch TV positioned too far results in a mere 20° field of view. Details become difficult to discern, and the cinematic immersion is lost. Gaming can also suffer, with on-screen text and UI elements appearing tiny and hard to read.
However, by moving closer to the same 43-inch TV, as shown in the image on the right, and achieving a 30° field of view, the viewing experience is dramatically improved. Details become clearer, leading to a more immersive experience for movies and games alike. User interface elements in games are now comfortably visible without requiring constant eye strain to take in the whole screen.
While a larger field of view enhances immersion, there’s a point where “bigger” becomes “too big.” Sitting too close to a very large TV can be uncomfortable, particularly with certain content. Watching fast-paced sports up close, for instance, can induce nausea as your eyes struggle to follow the action across such a wide display. Similarly, in gaming, an excessively large screen might force you to constantly scan around to see critical UI elements positioned at the edges, disrupting gameplay. While maximizing screen size for movies might seem appealing, it’s crucial to remember that not all content is designed for an overwhelming field of view.
Finding the sweet spot involves balancing immersion with comfort. The ideal range for TV viewing, according to experts, is between a 30° and 40° field of view. The chart above visualizes this “Goldilocks zone” for TV sizes ranging from 20 to 100 inches, represented by the area between the orange and blue lines.
TV Size to Distance Calculator: Finding Your Ideal Match
Now that we understand the importance of field of view, let’s translate this concept into practical TV size recommendations based on your viewing distance. The following chart provides guidelines for both “mixed usage” (30° field of view) and a more immersive “cinema distance” (40° field of view), according to recommendations from the Society of Motion Picture and Television Engineers.
| Screen Size | Recommended Mixed Usage Distance (30°) | Recommended Cinema Distance (40°) |
|---|---|---|
| 32″ | 4’4″ (1.32m) | 3’2″ (0.97m) |
| 40″ | 5’5″ (1.65m) | 4′ (1.22m) |
| 43″ | 5’10” (1.78m) | 4’4″ (1.31m) |
| 48″ | 6’6″ (1.98m) | 4’9″ (1.46m) |
| 50″ | 6’9″ (2.07m) | 5′ (1.52m) |
| 55″ | 7’5″ (2.27m) | 5’6″ (1.67m) |
| 65″ | 8’10” (2.69m) | 6’6″ (1.98m) |
| 70″ | 9’6″ (2.89m) | 7′ (2.13m) |
| 75″ | 10’2″ (3.10m) | 7’6″ (2.28m) |
| 77″ | 10’5″ (3.18m) | 7’8″ (2.34m) |
| 83″ | 11’3″ (3.43m) | 8’3″ (2.53m) |
| 85″ | 11’6″ (3.51m) | 8’6″ (2.59m) |
| 98″ | 13’3″ (4.05m) | 9’9″ (2.98m) |
| 110″ | 14’11” (4.55m) | 11′ (3.35m) |
| 115″ | 15’7″ (4.75m) | 11’6″ (3.50m) |
For general viewing and a comfortable experience across various content types, aiming for a 30° field of view is a solid starting point. If you prioritize a more cinematic, immersive movie-watching and gaming experience, the 40° recommendation provides a more engulfing picture.
These recommendations are guidelines, and personal preference plays a role. If you consistently watch movies and desire a theater-like feel, opting for a slightly larger TV within the 40° range might be ideal. However, avoid going significantly smaller than the 30° recommendation, as you risk losing detail and straining to see on-screen elements.
A helpful trick to visualize TV sizes in your space is to use painter’s tape to outline different screen dimensions on your wall. This allows you to physically compare sizes and get a feel for how each would fit in your room. Websites like Display Wars also offer visual TV size comparison tools.
Beyond Size: Other Factors When Comparing TVs
While size is a primary consideration, it’s not the only factor in choosing the right TV. Here are other important aspects to keep in mind when comparing TVs:
Source Quality and Upscaling
Don’t assume that a 4K TV automatically guarantees a 4K viewing experience. The quality of your content source is crucial. While streaming services offer 4K content, compression algorithms can introduce artifacts like noise, blurring, and pixelation, especially noticeable on larger screens. Understanding chroma subsampling and other compression techniques can help manage expectations regarding streaming quality. A larger screen will magnify these artifacts if the source quality is poor.
Size vs. Performance: Balancing Priorities
As larger TVs become more affordable, the question of prioritizing size over picture quality arises. For example, you might be choosing between a high-performance 65-inch OLED TV and a slightly lower-performing 77-inch OLED within the same budget. The optimal choice depends on your viewing priorities. While a larger screen is more immersive, superior picture quality, with better contrast, color accuracy, and processing, can significantly enhance the viewing experience, especially for discerning viewers. Strive for a balance – the largest high-quality TV that fits your budget and viewing distance.
Angular Resolution and Pixel Density
Angular resolution refers to the eye’s ability to distinguish fine details, and pixel density plays a key role. A lower resolution TV, like 1080p, viewed up close can appear pixelated because individual pixels become visible. Increasing viewing distance improves perceived pixel density. 4K TVs, with their significantly higher pixel density, minimize this issue, allowing for closer viewing distances without pixelation.
The chart below illustrates the optimal viewing distance for different resolutions based on TV size. While 4K has become the standard, understanding angular resolution helps appreciate why sitting closer to a 4K TV is beneficial to perceive its detail advantage over lower resolutions. 8K TVs further increase pixel density, making pixelation virtually nonexistent even at very close distances, but the benefits are most apparent on very large screens and with native 8K content, which is currently limited.
TV Dimensions Chart: Planning Your Space
Modern TVs boast incredibly thin bezels, meaning the screen size largely dictates the overall dimensions. When planning your setup, especially for wall mounting, these approximate TV dimensions by size class can be helpful:
| Screen Size | Approximate Width | Approximate Height | Area |
|---|---|---|---|
| 32″ | 27.9″ (70.9 cm) | 15.7″ (39.9 cm) | 438 in² (0.283 m²) |
| 40″ | 34.9″ (88.6 cm) | 19.6″ (49.8 cm) | 684 in² (0.441 m²) |
| 43″ | 37.5″ (95.3 cm) | 21.1″ (53.6 cm) | 791 in² (0.511 m²) |

| 85″ | 74.1″ (188.2 cm) | 41.7″ (105.9 cm) | 3090 in² (1.993 m²) |
| 98″ | 85.4″ (217 cm) | 48.1″ (122 cm) | 4103 in² (2.647 m²) |
| 110″ | 95.9″ (243.5 cm) | 53.9″ (137 cm) | 5170 in² (3.336 m²) |
| 115″ | 100″ (254.6 cm) | 56.4″ (143 cm) | 5651 in² (3.646 m²) |
These dimensions are approximate but offer a useful reference for comparing the physical footprint of different TV sizes.
Conclusion: Choosing the Right TV Size for You
For a balanced viewing experience suitable for various content, a 30-degree field of view is a reliable guideline. A simple rule of thumb is to divide your viewing distance in inches by 1.6 to estimate the ideal TV size in inches. If your calculated size exceeds your budget, prioritize getting the largest screen you can comfortably afford. Ultimately, these are recommendations, and with the prevalence of 4K TVs, picture quality is generally excellent across sizes. Focus on finding a TV size that feels comfortable and immersive for your viewing preferences and room setup. The goal is to enjoy your viewing experience, regardless of whether it perfectly aligns with calculated ideals.
