Is a 40 inch smart TV Worth It?

Best 40 Inch Smart TV

First off, a 40-inch TV hits that sweet spot between being too large for a small room and too small for a spacious living area. It’s versatile, fitting comfortably in bedrooms, offices, and even compact living rooms.

Now, let’s talk smart features. With the rise of streaming platforms and the decline of traditional cable, having a smart TV is almost a no-brainer. It offers the convenience of accessing your favorite shows, movies, and even some nifty apps without needing an external device.

Plus, with voice assistants becoming more integrated into these TVs, it’s like having a personal assistant ready to find that obscure movie you suddenly remembered at 2 AM. So, in my book, a 40-inch smart TV is not just worth it; it’s a modern-day essential.

TV Viewing Distance Size Chart

When it comes to TV viewing, distance matters. It’s not just about having the biggest screen; it’s about how that screen fits into your space. So, how far should you sit from a 40-inch TV? Let’s break it down.

For a 1080p resolution, the ideal distance is between 5 to 6.5 feet. If you’re lucky enough to have a 4K TV, you can cozy up a bit closer, around 3.5 to 5 feet.

But remember, these are just guidelines. Everyone’s comfort level is different. Some prefer to be up close and personal with their favorite characters, while others like a broader view. The key is to find a distance that feels right for you, ensuring you can see all the details without straining your eyes.

TV Size Viewing Distance
32″ ~5.0 feet / 1.52 m
40″ ~5.5 feet / 1.68 m
43″ ~6.5 feet / 1.98 m
50″ ~7.0 feet / 2.13 m
55″ ~8.0 feet / 2.44 m
60″ ~8.5 feet / 2.59 m
65″ ~9.0 feet / 2.74 m
70″ ~9.5 feet / 2.90 m
75″ ~12.0 feet / 3.66 m


Is OLED better than 4K?

OLED and 4K address different facets of a television’s display, making them not directly comparable. OLED, which stands for Organic Light Emitting Diode, is a display technology that employs self-lit pixels to produce images that are vibrant and lifelike, characterized by deep blacks and brilliant colors.

The unique feature of OLED is that each pixel can be individually controlled, allowing for unparalleled contrast and color precision. On the other hand, 4K pertains to a TV’s resolution. A 4K television possesses four times the pixel count of a standard 1080p HD TV, translating to a crisper and more detailed visual output.

Many premium TVs combine both OLED technology and 4K resolution, delivering an image that is both sharp and vibrant. The preference between OLED and 4K boils down to individual tastes: while OLED offers a more realistic image, 4K ensures a sharper and more intricate visual.


OLED and QLED are both advanced display technologies, but they differ in their mechanisms of image production. OLED utilizes self-lit pixels that can be individually controlled, resulting in profound blacks and vibrant colors. This technology doesn’t need a backlight, leading to a slimmer display with broader viewing angles.

In contrast, QLED, or Quantum Light Emitting Diode, employs quantum dots—tiny particles that emit colored light when illuminated. QLED TVs typically use a backlight to activate these quantum dots, producing images that are bright and vivid.

While OLED is often praised for its superior contrast, deep blacks, and expansive viewing angles, QLED is lauded for its brightness and color accuracy, especially in well-lit settings.

LG vs Samsung?

Choosing between LG and Samsung often boils down to individual preferences. If you’re inclined towards a brighter display, Samsung’s QLED TVs might be more appealing. However, if you prioritize deeper blacks and a more expansive viewing angle, LG’s OLED TVs could be the better choice.

Will a Smaller TV Offer Any Features?

Smaller TVs can both offer and lack certain features compared to their larger counterparts. The immersion level a TV provides is closely linked to its size. For instance, a 40-inch TV won’t provide the same level of immersion as a 75-inch TV. However, when considering features, it’s essential to note that many TV models come in various sizes but offer similar features across the board.

This means that a smaller TV might have the same functionalities as its larger version if they belong to the same model series. Features to consider include contrast ratio, viewing angle, response times, motion interpolation, 24p playback, and smart capabilities. When deciding on the best TV size or features, it’s crucial to consider both the technical specifications and personal viewing preferences.


Choosing the right TV size and understanding where to place it can feel like a daunting task. But once you’ve got the knowledge, it’s all about personal preference.

A 40-inch smart TV offers a blend of versatility, modern features, and a size that’s just right for many spaces. And while the viewing distance can vary based on resolution and individual comfort, the guidelines provided can serve as a starting point. At the end of the day, it’s all about creating a viewing experience that feels right for you.

So, whether you’re binge-watching the latest series, revisiting classic films, or cheering on your favorite sports team, make sure you’re doing it in a way that brings you the most joy. After all, that’s what TV watching is all about, right?
