# 16:9 TV Dimensions – Screen Size Chart > Reference chart showing width, height, and area for common 16:9 TV screen sizes **Category:** Media **URL:** https://complete.tools/tv-16-9-dimensions ## How it works This tool relies on the well-known 16:9 aspect ratio to calculate dimensions. By entering the diagonal measurement of a TV, it applies the Pythagorean theorem to find the width and height. The width formula is: width = diagonal * (16/√(16² + 9²)), and for height, it's height = diagonal * (9/√(16² + 9²)). These constant values ensure the calculations keep the right proportions, allowing for accurate area computations based on the derived width and height. ## Who should use this This tool is handy for anyone dealing with TV placements, like interior designers measuring spaces or architects planning entertainment areas. AV technicians setting up equipment will find it useful, too. Retailers can leverage this tool to help customers choose TVs that fit perfectly in their homes. ## Worked examples Let’s say you’re curious about the dimensions of a 55-inch TV. Using the formulas, you’d find that width = 55 * (16/√(16² + 9²)), which gives you approximately 47.94 inches. The height would be roughly 26.94 inches, resulting in a screen area of around 1286.29 square inches. Now, if you need a 75-inch TV for a media room, here’s how it breaks down: width = 75 * (16/√(16² + 9²)), landing you at about 65.32 inches. Height comes to around 36.76 inches, giving you an area of approximately 2401.45 square inches. These figures help you visualize how much space that TV will occupy. ## Limitations Keep in mind that this tool assumes a perfect 16:9 aspect ratio for all calculations, which might not be the case for every TV model. It rounds dimensions to the nearest hundredth, so there could be slight inaccuracies in precise spatial planning. The calculations focus solely on diagonal measurements, which don’t consider bezel sizes that might affect overall dimensions. Additionally, this tool is designed for conventional rectangular screens and doesn’t account for non-standard sizes or irregular shapes. ## FAQs **Q:** How do I determine the width and height of a TV with a different aspect ratio? **A:** The formulas here are tailored for the 16:9 aspect ratio. For other ratios, you’ll need to create new constants and go through similar calculations. **Q:** Can I use this tool for projectors with a 16:9 aspect ratio? **A:** Absolutely! This tool works for projectors as long as they maintain that 16:9 aspect ratio. **Q:** Why is calculating screen area important? **A:** Knowing the screen area helps you figure out how much physical and visual space the TV will occupy, which is crucial for layout decisions. **Q:** Do screen curvature affect these calculations? **A:** No, this tool assumes flat screens. While curved screens can change the viewing experience, they don’t alter the basic width and height derived from the diagonal measurement. --- *Generated from [complete.tools/tv-16-9-dimensions](https://complete.tools/tv-16-9-dimensions)*
