What is Aspect Ratio?

In simple words, the aspect ratio as the relationship between the height and width of the projected image. Imagine you had a TV that was 40 inches wide and 30 inch high, it will have the aspect ratio of 40 by 30. Essentially, in modern terminology, this ratio is equal to 4:3. Similarly, it is the aspect ratio that defines the correlation between width and height of an image. However, it doesn’t describe the actual size of the display. If you closely look at the screen, you’ll notice whether the picture is square or rectangular. Regarding aspect ratio, all new projectors allow you to adjust according to the size of your screen. This process is done electronically and attempts to fit the projected image according to the width and height of the screen. But, the details of your image depend on the aspect ratio. Not all aspect ratios are perfectly displayed on your screen.

Types Of Aspect Ratios

In most cases, some of the image quality will be lost. Another thing to note is that different aspect ratios show images in a variety of ways. Choosing a larger aspect ratio may allow your projector to display videos and pictures accurately, but not the text. The text will appear smudged and blurry but will work fine with images. Choosing 16:9 aspect ratio means that your screen is 16 units high and nine units wide. This resolution is considered perfect for high-resolution HDTV displays like LED TVs and even theaters. Similarly, the 4:9 ratio, having a four units wide and three units high image will work best for smaller screens like computer monitors. Keep in mind that you must be aware of the aspect ratio that your projector screen or theater supports. Displaying large aspect ratio images will make them appear strange on a small picture. They’ll have choppy image quality, and the screen will cut both the width and height to fit it in that aspect ratio. If the aspect ratio is too low, your screen might not even be able to render the image correctly. Similarly, when you project small aspect ratio images on higher aspect ratio screens like 16:9, or 2.40:1 theater mode, your image will appear stretched and will lose its quality. Nothing you want when you are trying to watch a movie of play some games…

Choosing The Best Aspect Ratio For Your Screen

Like we said before, if you select the right aspect ratio, your projector will have enough juice to churn out the high-quality images, videos, and text. But, it all comes down to the device on which the projected image will be displayed. Larger aspect ratios are more suitable for higher resolution displays like theater, HDTV, Blu-ray and widescreen DVD displays. In fact, these devices are meant to display high definition content and are an ideal fit for watching high aspect projected images. For our purposes, modern projectors work best with a 16:9 projector screen. Some screens go to 16:10, this is good as well. The image might be a little stretched with 16:10 resolution, but some people get used to it and like it better than the usual 16:9 ratio. 

If you prefer smaller aspect ratios, pick a screen that supports that ratio. (It’s not rocket science)

So, the next time you want to buy a projector screen, make sure you look into the specs, especially the aspect ratio of the screen that you feel will give you the best fit for your projector.
