![]() ![]() You can also find an aspect ratio calculator online if you’re not mathematically inclined. If you remember your Pythagorean theorem, you can use that and the aspect ratio together to determine the exact dimensions of the image or screen. If you want to replicate a true theater experience, you’ll want a cinema aspect ratio of 2.35:1. HD movies and TV shows have an aspect ratio of 16:9. If the aspect ratio is 2:1, the width is twice the height.ĭifferent forms of content have different aspect ratios. If the aspect ratio is 1:1, the width and height are equal. This spec tells you the relationship of the image width and height, expressed as a mathematical ratio. This is where the projector’s aspect ratio comes into play. Just like in geometry class, you’ll need both the length and the slope of the hypotenuse to figure out the screen’s dimensions. This diagonal can be the hypotenuse of an infinite number of right triangles, though. If you want to get the screen’s dimensions from the screen size, you’ll need to think back to your high school geometry classes.ĭrawing a diagonal across a rectangular screen breaks it into two right triangles, with the diagonal serving as the hypotenuse of each. You might be trying to figure out where in your home will be the best fit for the screen, for example. Extrapolating length and widthįor some situations, just knowing the diagonal won’t be enough. If you want to figure out the size so you can match your projector to the right screen, or for the sake of comparing one screen to another, you can generally do so with just this information. This is also the measurement that will be used for the screens themselves. Similar to televisions, projector images are measured on the diagonal. Figuring out which dimension this represents-and how to extrapolate the rest of the image size from this information-is your first step. ![]() With projectors, though, you’ll see only a single measurement listed under the screen size. Read on below for all the answers! How are projector screens measured?įor most products, it’s typical to see the size listed in terms of its dimension: one number for the length, and another for the width. ![]() The good news is, it’s pretty easy to figure out a projector’s screen size, both in terms of the maximum potential dimensions and the change in size you’ll get when you move the projector further from or closer to the screen. But how much bigger-and how can you tell? The measurements listed on the product description are only as helpful as your ability to interpret them, and they don’t always make it obvious how to compare them. It’s common knowledge that a projector will give you a larger screen for your home theater than your average television. ![]()
