When you’re on the hunt for a new TV, size is one of the most crucial factors to consider. With an array of options available in the market, it can be overwhelming to figure out which size suits your space and needs best. The 42-inch TV stands as a popular choice, offering a good balance between compactness and size for a variety of settings. In this guide, we will explore 42-inch TV dimensions, how to measure a TV properly, tips for choosing the right 42-inch TV for your room, and more, so you can make an informed decision.
What Does 42-Inch Mean in TV Size?

The “42-inch” measurement refers to the diagonal length of the screen, from one corner to the opposite corner. This is the most common way to describe the size of a television. However, this number doesn’t tell you the width or height of the TV, so understanding the exact dimensions of a 42-inch TV is crucial when determining if it fits your available space.
A 42-inch TV is considered a mid-sized television and has been a popular option for smaller living rooms, bedrooms, and apartments. It’s not too big to overwhelm smaller spaces, but it still offers an impressive viewing experience for everyday TV watching.
What Are the Exact Dimensions of a 42-Inch TV?
For a standard 42-inch TV with a 16:9 aspect ratio, the general dimensions are as follows:
- Width: 36.6 inches (approximately 93 cm)
- Height: 20.6 inches (approximately 52.4 cm)
- Depth (without stand): 2.9 to 3.5 inches (approximately 7.4 to 8.9 cm)
- Depth (with stand): 7.0 to 9.0 inches (approximately 17.8 to 22.9 cm)
These measurements may slightly vary depending on the brand or design of the TV. For instance, TVs with ultra-thin bezels or certain designs may have different dimensions, so it’s always a good idea to check the manufacturer’s specs for the most accurate details.
How to Measure a TV’s Dimensions Correctly

It’s important to note that the 42-inch label only refers to the diagonal measurement. To ensure that the TV fits in your desired space, you need to consider the width, height, and depth:
- Measure the Diagonal Size: Use a measuring tape to measure from one corner of the screen to the opposite corner diagonally.
- Measure the Width: To know how much horizontal space the TV will take up, measure the distance from one side of the screen to the other (not including the stand).
- Measure the Height: Measure from the bottom to the top of the screen (excluding the stand). This will help you determine how much vertical space the TV will occupy.
Having these measurements in hand will help you figure out if the TV fits well on your TV stand, wall, or in the desired spot.
How to Choose the Best 42-Inch TV for Your Space
Choosing a 42-inch TV isn’t just about the size; there are other features to consider that can impact your viewing experience. Here are some things to look for when selecting the best TV:
1. Viewing Distance
The ideal viewing distance for a 42-inch TV typically ranges from 5 to 7 feet (1.5 to 2.1 meters). This will provide the best viewing experience, where you can enjoy the full HD or 4K resolution without any pixelation or strain on your eyes. For larger rooms, you might want to consider a slightly larger TV, while for smaller spaces, a 42-inch TV is perfect for close-up viewing.
2. Screen Resolution
For a TV of this size, you should consider the resolution based on your usage. Here are your options:
- Full HD (1080p): This is a good resolution for casual viewing or if you are on a budget.
- 4K: If you’re a fan of high-definition content or gaming, a 42-inch 4K TV will offer sharp, detailed visuals. With 4K content becoming more common, this resolution provides future-proofing for a better viewing experience.
3. Smart Features
Today’s televisions come with built-in smart capabilities, which let you stream content from popular apps like Netflix, YouTube, Amazon Prime, and more. Consider whether the TV has Wi-Fi connectivity and voice control features like Alexa or Google Assistant to enhance your viewing experience.
4. Ports and Connectivity
For seamless connections to other devices, ensure that the TV has enough HDMI ports for gaming consoles, Blu-ray players, soundbars, or streaming devices. You may also want USB ports, Bluetooth connectivity, and audio out options depending on your needs.
5. Audio Quality
While most modern TVs offer better sound than older models, the audio quality in a 42-inch TV might not be top-tier. If you want richer sound, consider adding external speakers or a soundbar to complement your TV’s audio.
