Choosing the right television size isn’t just about picking the biggest screen your budget allows. A TV that’s too large can overwhelm a room, while one that’s too small might leave you squinting at details. If you’ve ever wondered, how to measure a TV correctly, you’re in the right place! This TV size guide will walk you through the process of measuring a TV properly, understanding TV sizes, reviewing popular sizes, and helping you choose the perfect screen for your space.
Understanding TV sizes and how they are measured
Many shoppers assume that the listed size refers to the TV’s overall dimensions. But in reality, it only represents the screen size, measured diagonally from one corner to the opposite corner. For example, a 55” TV means the screen itself measures 55 inches from corner to corner. This measurement excludes other key components such as the bezel—the frame around the screen—as well as the casing, stand, and wall mount brackets. If you’re planning to get a new TV, make sure it fits well within your space. Measure the entire unit’s width, height, and depth separately to ensure a proper fit.
Most TVs today follow a 16:9 aspect ratio, meaning their width and height are standardized. However, ultra-wide or specialized gaming screens may have different dimensions, so checking the product specifications is always recommended. Additionally, you might come across TVs labeled with a “class” designation, such as a “55-inch class.” The term “class” refers to a general size category rather than an exact measurement. Due to manufacturer rounding and slight variations in panel production, the actual screen size is often slightly smaller. For example, a 55-inch class TV may have a display measuring around 54.6 inches. This discrepancy exists because manufacturers round up to the nearest whole number for marketing consistency.
While most brands adhere to the diagonal measurement standard, there may be minor differences due to manufacturing variations. For Canadian shoppers, it’s useful to convert inches to centimetres: One inch equals 2.54 cm, so a 55” TV is approximately 140 cm diagonally. Keeping these factors in mind ensures you select the right TV size for your space without surprises.
How to measure a TV properly
Follow this step-by-step process to measure your TV and avoid any fitting issues when setting it up in your space.
Step 1: Measure diagonally
Start by placing your tape measure at one corner of the screen, and extend it to the opposite corner to get the official TV size. This is the standard method used by manufacturers to measure the screen and is what’s listed on the product box. It’s crucial because it gives you the exact size of the screen (excluding the bezel).
Step 2: Measure width and height
To ensure the TV fits into a space, such as on a stand or mounted on a wall, it’s important to measure the full width and height of the unit. This includes the bezels, which are often not considered when measuring the screen itself. By measuring the dimensions, you can make sure that the TV won’t be too large for your furniture or wall and prevent potential installation issues.
Step 3: Measure depth and stand
If your TV includes a stand, measuring its depth is essential for determining how much space it will take up on your entertainment unit. This helps to ensure stability and prevent the TV from tipping over or overcrowding other furniture. Some stands can be bulky, so knowing the depth in advance allows you to choose the right placement and ensures your TV stays securely in place.
Tips for accurate measurement
- Use the right tools: A retractable tape measure works best because it’s flexible and can easily stretch across large TVs. If the TV is large, it might be helpful to have someone assist you in holding the tape at both ends to get an accurate measurement.
- Avoid common mistakes: One of the most common errors is not including the bezel when measuring for placement. While the official TV size is measured diagonally across the screen (excluding the bezel), you’ll want to include the bezel’s dimensions when you’re measuring the TV to ensure it fits properly in your space, whether it’s on a stand or mounted on the wall.
- Check manufacturer specifications: For the most accurate fit, always refer to the manufacturer’s specifications. The specs often list the exact dimensions of the TV, including width, height, depth, and stand. They can help clarify any uncertainties and give you precise measurements for fitting.
Popular TV sizes and what they are best for
- 32″ and smaller: Great for kitchens, bedrooms, and small spaces. They’re perfect for users who need a secondary TV or have limited space, such as in apartments or dorm rooms. Cooking dinner or getting ready while streaming your favourite TV show in the background? You can benefit most from smaller TVs.
- 33″-42″: Ideal for medium-sized rooms and apartments. These TVs offer a balanced viewing experience without overwhelming the space. They’re great for users who enjoy watching TV in a living room, guest room, or even a larger bedroom. If you don’t have a dedicated home theatre setup but still want a screen that provides a good mix of size and picture quality, you’ll find this range perfect for everyday use.
- 43″-49″: A solid choice for general living room use. These sizes strike a balance between a spacious viewing experience and ease of placement. They’re ideal for families or individuals who enjoy a more immersive experience without it dominating the room. Homeowners or renters with moderate-sized living rooms will appreciate these TVs. They provide a clear and crisp picture that’s perfect for everything from movie marathons to sports games. Gamers will also love these sizes for an enhanced experience without needing a massive screen.
- 50″-54″: Perfect for larger rooms with a more immersive experience. These sizes are great for people who want a bit more presence in their viewing area but don’t necessarily want to go for the largest models available. A family looking for a TV for movie nights, or individuals who enjoy streaming high-definition content, will find these sizes ideal. They also fit well in larger living rooms or open-concept spaces, adding a cinematic feel without being too overwhelming.

If you have a large living room or a dedicated home cinema area, a 65” or larger TV creates an exceptional and cinematic experience.

These sizes offer a dramatic viewing experience that’s hard to match. You will love the larger-than-life visuals these screens provide.
How to choose the right TV size for your room
Find the ideal balance between screen size, comfort, and practicality. Consider factors like how far you’ll sit from the screen, the layout of your room, the type of content you watch, and future technology trends.
Viewing distance
The ideal viewing distance depends on the size of your TV. Use this simple rule: TV size (in inches) × 1.5 = ideal viewing distance in inches. For example, a 55” TV should be viewed from 83 inches away (6.9 feet away). Sitting too close to a large screen can cause discomfort, while sitting too far from a small screen can make it harder to see details.
Room size and layout considerations
Your TV should complement your room’s layout rather than dominate it. A TV that is too large can overwhelm a small space, while a TV that is too small may not provide an immersive experience in a large room. The layout of your furniture, available wall space, and the distance from which you’ll be watching all play a role in your decision.
Consider where you’ll place it—on a stand or wall-mounted—and ensure there’s enough space for comfortable movement around it. Wall-mounting can be a great option to save space and create a clean, modern look. If you’re using a TV stand, ensure it’s sturdy enough to support the weight of your chosen TV size.
Consider surrounding it with stylish shelving or a media console that matches your furniture. Opt for a frame-style TV that blends into the wall when not in use. Or use a cord management system to keep wires hidden and maintain a clutter-free aesthetic. Additionally, positioning your TV in a spot with minimal glare from windows and lights will enhance your viewing experience while keeping your space looking polished.
Content type influence
Different types of content can impact your ideal TV size:
- Movies: A larger screen enhances the cinematic experience, making it easier to appreciate details and immerse yourself in films.
- Gaming: Gamers may prefer a size that fits their field of view comfortably. A screen that’s too large can require excessive head movement, while one that’s too small might make it hard to see fine details in competitive gaming.
- Sports: Watching sports benefits from a bigger screen, allowing you to follow fast-paced action more easily and see details clearly, such as player movements and game stats.
Future-proofing your purchase
TV technology is constantly evolving. Features like 8K resolution, mini-LED, OLED panels, and higher refresh rates are becoming more common. With more spectacular content coming out, these innovations enhance picture quality, improve contrast, and offer smoother motion. If you plan to keep your TV for several years, choosing a model with advanced features can help extend its lifespan and provide better picture quality over time.
Additional considerations
Aside from TV size, consider key features like resolution, display type, and budget to get the best experience. These factors impact picture quality, viewing comfort, and overall satisfaction with your purchase.
Resolution
- HD (720p): Suitable for small TVs, such as those used in kitchens or guest rooms. While it provides decent picture quality, it’s becoming less common as higher resolutions become more affordable.
- Full HD (1080p): A Full HD TV works well for budget-conscious buyers who want better clarity without a big price tag. It’s perfect for medium-sized screens where 4K isn’t necessary.
- 4K (UHD): The current standard for sharp visuals, it offers four times the resolution of Full HD and provides excellent detail. It’s a great choice for many of the latest TVs, especially those 43 inches and larger.
- 8K: Though ideal for premium large screens, they’re not widely supported yet. TVs with 8K resolution deliver incredible clarity, but there’s limited content available. It’s more of a future-proof investment rather than a necessity today.
Display type
- LED: Affordable with good brightness, LED TVs are the most common TV type. They’re great for well-lit rooms but may have slightly lower contrast compared to other display technologies.
- QLED: With better colours and brightness, QLED TVs are excellent for those who want a more vivid and dynamic picture, especially in bright environments.
- OLED: OLED TVs have deeper blacks and better contrast due to its ability to turn off individual pixels. Because of its superior picture quality, OLEDs are the top choice for home theatre enthusiasts seeking the best cinematic experience.
Budget considerations
While larger screens and advanced technologies offer better picture quality, they also come at a premium. A 55” 4K TV often provides the best mix of performance and affordability, delivering sharp visuals without breaking the bank. If you’re on a tighter budget, a 43” 4K or a 50” Full HD model can still offer a great experience. Consider investing in higher-end features like OLED or QLED if you prioritize picture quality. But if affordability is your main concern, LED TVs remain a solid choice.
Find the right TV for you
Getting the right TV starts with proper measurement, understanding screen sizes, and considering placement within your space. By factoring in viewing distance, room layout, and content preferences, you can find the perfect balance between size and comfort. Whether you need a compact screen for a bedroom or a massive display for a home theatre, there’s an ideal option for every setup. Take a moment to visualize how a new TV would fit into your space, ensuring it enhances your viewing experience without overwhelming the room.
