What Are Short-Throw Projectors?

Making a new purchase can be challenging, especially when there's no shortage of options around you. And of course, when it comes to projectors there's a lot to consider: All the terminology, the specs, and the different types.

So today we want to make things easier for you by providing a thorough explanation of what Short-Throw projectors are. This is a term you've likely seen often if you browse for projectors, and they are a great option to consider for your next purchase. So let's go deep into the world of Short-Throw projectors and discover what they offer, what kind of uses they are best for and just why they are so common nowadays.

What Are Short-Throw Projectors?

A short-throw projector is any projector that projects close to the screen, hence the "short-throw" moniker: It's throwing its display a short distance. Ultimately this means that these projectors save space and allow you to set up a projection even if you don't have a large area, which makes them popular in apartments and other compact living spaces.

Another perk to keep in mind is that while these projectors used to be far more expensive due to the small components they are now more affordable than ever, so they are a comfort you can access without breaking the bank.

The term short-throw comes from the "throw ratio" which is the ratio between the image and projector. All projectors have a throw ratio, and in the case of short-throw models, theirs is well, short.

How Do Short-throw Projectors Work?

Now, let's take a deeper look at the inside workings of these practical little devices. While it might be shocking to think that these devices can project such a large image at a small distance it comes down to two main factors.

First is the high-quality lens. These lenses ensure that the image quality is optimal and that your projector provides the best possible experience possible, however, to achieve this quality the lens is fixed and it's not possible to zoom or adjust the projection at all. This is why it's so important that you make sure your projector's distance to the screen is perfect.

The other important factor is the projector's geometry correction chipset. It might sound complicated, and the inner details can get confusing. But in short, this chipset warps the image just right so that the projected image ends up looking normal. The projected image is perfectly calibrated to the angle and distance, and this is what allows short-throw projectors to display their images despite the short distance.

Different Types Of Short-throw Projectors

Not all short-throw projectors are the same, and this means that there are 4 main types of short-throw projectors we'll need to take a look at.

Hi-Def Short-Throw Projector: Hi-Def projectors provide sharp quality of at least 720p and are compatible with most output and input types making them practical and easy to use.

1080p Short-Throw Projector: At 1080p you'll be noticing an increase in quality compared to the previous models, which will result in clearer images and an improved user experience. Many of these devices also have integrated speakers making these projectors integrated entertainment solutions.

4k Short-Throw Projector: 4k projectors have roughly 8 million pixels on every image ensuring the highest picture fidelity and quality possible. Images will be more vivid, the colors will be more accurate and you can also expect an improved sound system.

Laser Short-Throw Projector: Laser projectors don't rely on lamps or bulbs that need replacing which means not only do they provide a better image but they last longer and are far easier to maintain than the alternatives. The WEMAX Nova 4K is a great example of a laser projector that not only uses this improved technology but also displays in 4k providing the best possible short-throw experience in the market.

Pros And Cons Of Short-Throw Projectors

Every technology has its own set of perks and drawbacks, and while short-throw projectors are solid pieces of technology there are still some things you should consider before settling down on a purchase. So for now let's take a closer look at the pros and cons of short-throw projectors.


The shorter throw ratio means these projectors require less space and shorter cables; saving you both space and effort.

Their positioning means they don't cast shadows on the projection and that there's less heat and sound disturbance.

The larger projection reduces eye strain and makes the experience far more immersive.


Short-throw projectors can easily heat up due to the extra processing power they require to function compared to other models.

Due to the aforementioned heating, the cooling fans can become noisy on these models.
