How to Choose a Projector – Buying Guide

When you’re trying to find a good projector, there are a lot of different factors that you’re going to want to take in to account. This way, you can be sure that you’re going to choose the right projector to meet your needs.

We’re going to take a look through all the different criteria that you’ll want to consider before you invest in a projector. This includes everything, from the brightness of it’s lights, to the technology used within the device itself. So, let’s look at some of the things worth thinking about when looking for a new projector.

How to Choose a Projector

When you’re buying a projector, you need to take these 6 main things into account; Price, Room Size, Projector Type, Brightness, Resolution and Use. When you’ve looked at all of these factors, you should be able to find the right model for you.

Let’s take a closer look at all of these aspects in more detail.


The first thing that you’re going to want to think about when buying a projector is the price. With projectors, you can really spend as much as you want, because many of them go into the severals thousands depending on what you need.

For most people, I don’t think that you need to spend that much to get a home projector. Check out my list of the best projectors under £500, which proves that you don’t need to spend a lot of money to get a good quality device. But anyway, before you get started you should set your budget, whether that’s £200 or £2000.

Room Size/Distance

The main thing to think about when you’re about to purchase a projector is the size of the room you’re going to use it in, and the projectors distance from the projector screen.

If you’re looking for a projector for a home theater, then you’re likely to want a short throw projector. However if you’re looking for something to use in the office, or in a lecture hall, this is where you’d opt for a long throw projector instead.

When we say short throw, the distance that you’ll usually have the projector from the screen isn’t that short. If you place a short throw projector 6 feet away from the screen, then you should get a 100 inch screen projector. You do also get ultra-short throw projectors, which can project a 100 inch screen from only a few inches away.

In most cases, we’re going to want to opt for a short throw projector. Whilst long throw projectors do have a place in the projector world, they’re not the best choice for home use.

Projector Type

Another important thing that you’re going to want to take into account when purchasing a projector is the type of technology that the projector uses.

For consumer use, there are three different types of technology that we generally use in projectors. The most common of these is the DLP projector, which uses light pushes through a colourwheel onto small mirrors to create an projection. Have a look at this comprehensive explanation of DLP projectors.

Another type of projector is a 3LCD, sometimes referred to as just a LCD projector. These projectors use 3 display panels, in red, green and blue, which combine together to project an image. They tend to be better in colour production than DLP’s, but the difference isn’t that noticeable for most people.

We also has LCOS projectors, which are going to be too expensive for most of us (we’re talking several thousands and upwards for an LCOS projector). They’re etter than both LCD and DLP projectors for the most part.

In most scenarios, a DLP projector is going to be the best option if we’re looking for the best compromise of value and performance.


Another one of the main things that you’re going to want to consider when purchasing a projector is the brightness. You’re going to find there’s a difference with watching a projector and a TV, and it might just take a little getting used to.

The brightness of the projection is going to be relative to the distance it is from the screen. So, if you have your projector 4 feet away from the screen producing an 80 inch image, this will be brighter than 6 feet away projecting a 120 inch image.

We measure the brightness of a projector in lumens, so you’ll be able to measure it’s luminosity by checking this out. Bear in mind that you’ll find cheap projectors all over the internet that state they have a lumens measurement much higher than the reality. So, if you want a truly bright projector, stick with a trusted brand.

If you’re going to be watching films in the dark anyway, then the brightness won’t matter to you too much. But if you plan to use your projector in an area with a lot of windows or light, then it’s a much better choice to get a projector with a higher level of brightness.


Another thing to consider with your projector is it’s resolution. With DLP projectors, this is dictated by the amount if mirrors that it uses to reflect the light to portray the image.

You’re going to find an even bigger difference between a 720p or 1080p projector compared to a 4K projector than you would with a television. A 4K projector just uses four times the amount of pixels that a 1080p projector does, so it should give you a much clearer picture.

This will all come down to your budget, and how much you’re looking to spend on a projector. If you have money to spend, then opt for 4K. If not, then there’s nothing wrong with a cheaper 1080p projector instead.


The final thing that you’re going to want to think about when choosing a projector is what you’re going to use it for. This will dictate which projector you end up choosing, so it’s really important.

If you’re looking for a projector for a home theater, then opt for a DLP projector; the best you can afford. If you’re looking for a projector to play games on, then you might need a projector with more contrast and minimal input lag – a DLP projector is best for this too.

However if you’re looking for a projector to use in a brighter room, then you might want to consider a different type of projector.


When you’re going to get yourself a projector, these are the main things that you’re going to want to consider. As long as you know what you’re going to use your projector form, then you should be able to find a good model that will fit your needs perfectly.
