Picking the best aspect ratio for your projector

Introduction to Aspect Ratios for Projectors

The manner in which images are framed has always been a factor when discussing the world of film and media. People who grew up watching TV during the nineties or 2000s should be familiar with the square televisions that were popular at these times. The near-square videos became popular, and then eventually these TVs transitioned to wider formats - more rectangular than square - and these were known as HDTVs (16:9 aspect ratio). However, in recent years there has also become a need for more traditional screens that are closer to what older generations had (4:3) due to people preferring them over today's modes. When it comes down to it all, viewing habits come first before anything else; while there is usually something meant for every person out there, if you don't care much about immersion then chances are 4:3 would suit your needs best. Fortunately though, projectors nowadays can give you options depending on what suits your needs best.We recommend FATORK projectors that offer flexibility in aspect ratios.

What are the Common Projector Aspect Ratios?

The ratio of the width of a projector's image to its height determines how tall an individual screen will be, or what kind of shape it will have. A 16:9 aspect ratio means that every sixteen lengths measured on the display's width represent nine lengths in height and that you should expect a widescreen display when using this proportion. Most projectors today can display video content in different proportions for various settings such as at home theaters and offices with varying needs for cinematic experiences.
At home theaters, the 16:9 aspect ratio is the norm for most movies watched today because of its versatility and ability to provide viewers with extra viewing space than other ratios like 4:3 which are commonly found at office spaces. So whether you want theater-like viewing experience or something more suited towards productivity - there's always an option out there just waiting to meet your needs!

Common Aspect Ratios

While there are several other types of projector aspect ratios like cinemascope and 16:10, 4:3 and 16:9 are more prevalent in business, home theater, and other applications.


The 4:3 aspect ratio is the earliest used in broadcast television, film, and computer displays. For a long time, it served as the standard in the United States. Traditional television sets of the non-high definition format, SVGA, XGA, and UXGA projectors display in a native 4:3 format.

Its dimensions are closest to the field of vision of the human eye and are almost like a square. Any display in the 4:3 aspect ratio is 1.33 times as wide as high. For example, if the display height is 50 inches, its width would be (50 × 1.33) inches, which equals 66.5 inches.


The 16:9 format is currently the most common aspect ratio. Today, 16:9 is the standard for most modern televisions and projectors. Since most video content creators and filmmakers adopt the 16:9 format, most projectors have a default 16:9 aspect ratio. You would find an easy example of a 16:9 screen when you look at a flat-panel television.

Dimensionally, the 16:9 aspect ratio offers a screen 1.78 times as wide as it is high. A 60" high screen, therefore, would have a width of (60 × 1.78) inches, which equals 106.8 inches. The 16:9 aspect ratio was designed to accommodate high-definition resolution and provide a more immersive experience than earlier formats.

4:3 vs. 16:9

Projector screens come with a fixed aspect ratio. Some can be 4:3 or 16:9, and you can quickly tell the difference as one is shaped almost like a square while the other is considerably wider. Projected content also comes in different aspect ratios. For classic television shows or vintage movies, 4:3 is more common, while today's movies and TV shows use 16:9. Here's how both aspect ratios would appear on your projector screen:

● If you have a 4:3 screen (square-like), any video in a 4:3 aspect ratio will fit the screen perfectly, leaving no black borders, while a 16:9 video will not fit the screen, leaving horizontal black borders above and below.

● If you have a 16:9 screen (more rectangular than 4:3), any video in the 4:3 aspect ratio will not fit the screen, leaving vertical black borders on both sides of the display. Video content with the 16:9 aspect ratio will fit the screen perfectly, leaving no black borders.

Also, you can crop (zoom) or stretch videos in other aspect ratios to fit your projector screen, although the image may be visibly altered.

What Aspect Ratio is Ideal for Me?

Choosing the perfect aspect ratio depends on a few things: what size your projector screen is, which type of projection it can handle, what kind of content you're projecting, and most importantly - the room it's going in.

Living room

Living rooms are often the largest spaces in homes. They're meant to be a relaxing place where people can come together and watch their favorite content. The 16:9 ratio is much better for movies than the 4:3 display because it allows for an immersive experience without sacrificing too much wall space.

Home Theater Rooms

Since most movies are filmed using the 16:9 aspect ratio, they are ideally suited for living rooms and other home theater setups. With a little bit more space on either side of the frame when you watch something in this format, filmmakers can add in details that might not fit at all if they were shot with the 4:3 aspect ratio. This makes for an immersive viewing experience where your vision feels immersed within what's happening on-screen; supporting higher resolutions than 4K or 1080P formats would.


The projector in my bedroom projects movies and TV shows onto the walls, as well as educational content. The 16:9 aspect ratio is optimal for these types of productions because it gives more fits-to-screen displays without black bars at the top and bottom that are often distracting.


For offices and more professional settings, less emphasis lies on high-resolution or immersive viewing. In such settings, a 4:3 aspect ratio is ideal as it is easier on the eyes and great for presentations.

Dorm Rooms

Dorm rooms may have less width to work with than living rooms or home theater rooms, and aesthetics are not exactly a priority. In such settings, a 4:3 aspect ratio is ideal as it works with the available space.
