As technology evolves, TVs continue to grow in size and quality. If you've recently upgraded to a sleek new model, you might be wondering the best way to measure it for display. Maybe you're evaluating whether a prospective TV will fit your stand. Fortunately, measuring a TV is remarkably simple and typically takes just a few seconds. This guide teaches you the proper techniques to measure a TV accurately and ensure it fits flawlessly into your space.
Key Points to Consider
- Measure the diagonal screen size to determine the screen size.
- Measure the height and width of the TV frame to confirm compatibility with your stand or cabinet.
- Ensure the TV has adequate space on all sides for proper ventilation.
Step-by-Step Guide
Discover the Dimensions

- Common TV sizes based on diagonal dimensions include 24 in (61 cm), 28 in (71 cm), 32 in (81 cm), 42 in (110 cm), 48 in (120 cm), 60 in (150 cm), 65 in (170 cm), 70 in (180 cm), and 85 in (220 cm).
- You can also find TVs with screens as large as 98 in (250 cm) or even larger.
- The current largest TV available for household entertainment is LG's 8K DVLED TV, boasting an impressive 325 in (830 cm).
Pro Tip: Focus on the Screen, Not the Frame

- For instance, a TV advertised as 60 in (150 cm) will typically have a width of around 52.3 inches (133 cm).
- The width is the crucial measurement for determining if a TV will fit your stand or cabinet.

- For example, a TV with a 48 in (120 cm) advertised screen size will typically be about 42 inches (110 cm) wide and have a height of approximately 25–27 inches (64–69 cm).
- While width is more critical, height can still impact placement decisions.

- Consider TV depth to ensure compatibility with existing furniture like cabinets or stands.
- Modern flat-screen models are often less than 10 inches (25 cm) deep with a stand and as slim as 3 inches (7.6 cm) without. In contrast, older CRT televisions are significantly thicker, necessitating special consideration.
Ensure TV Compatibility

- For precision, round measurements to the nearest half-inch (1.3 cm).
- Keep your display space dimensions handy while shopping for a new TV.

- Extra space around your TV promotes ventilation, preventing overheating.
- For wall mounting, use a mount rated for your TV's size and weight to avoid accidents.

- For example, if you're seated 72 inches (180 cm) away, a 60 in (150 cm) TV provides optimal visibility.

- Standard TVs, with their 4:3 aspect ratio, present images in a square format, while widescreen TVs showcase the full picture with enhanced width.
- Despite sharing the same diagonal screen size, standard and widescreen TVs deliver vastly different viewing experiences.

- For instance, upgrading from a 40 in (100 cm) standard TV requires a widescreen TV of at least 50 inches (130 cm) to preserve picture size.
- Additionally, widescreen HDTVs offer superior resolution compared to standard TVs, resulting in sharper image quality.
Helpful Advice
-
If budget is a concern, explore alternative TV styles within the same size range. A 50 in (130 cm) LED TV typically offers better affordability compared to a 50 in (130 cm) OLED 4K HDR TV.
