Key Takeaways
- A megapixel refers to one million pixels, so 8.29 million pixels is equivalent to 8.29 megapixels.
- The most common resolutions associated with 4K are 3840 x 2160 pixels and 4096 x 2160 pixels, both of which result in approximately 8.3 megapixels.
- 4K resolution is often used interchangeably with the term “Ultra High Definition” (UHD).
- 4K offers four times the pixel resolution and twice the line resolution of 1080p, resulting in a significantly clearer and more detailed image.
- The difference between 4K and 1080p is more noticeable on larger screens, while smaller screens may not fully showcase the benefits of 4K.
- When considering a home theater setup, High Dynamic Range (HDR) can greatly enhance the viewing experience by improving contrast and color reproduction.
- The number of pixels (megapixels) in a camera is just one aspect to consider, with sensor size and lens quality playing significant roles in image quality.
- Megapixels alone do not guarantee a great image; factors such as sensor size and lens quality are equally important in producing impressive photographs.
How Many Pixels are in a Megapixel?
Before we explore the number of megapixels in a 4k frame, it’s worth touching briefly on what the term ‘megapixels’ is even referring to. To cut to the chase, there are one million pixels in each megapixel.
So for example, 8,294,400 pixels is equivalent to 8.29 megapixels. This could also be written in its ’rounded up’ form as 8.3 megapixels. Why have we chosen such a specific figure in this example?
We explain below.

4k Vertical and Horizontal Pixel Count
When people use the term ‘4K,’ they’re usually referring to one of the following:
- An aspect ratio of 3840 x 2160 pixels
- An aspect ratio of 4096 x 2160 pixels
The 4096 x 2160 pixels ratio (4K video) is typically used in commercial digital cinema for its higher resolution and professional production value.
Higher resolutions such as 8K exist and are also used, but 4K resolution is the most widespread thanks to its ubiquity and relative affordability.
So, how many megapixels are you dealing with in this 3840 x 2160 resolution? You guessed it – it’s 8,294,400 pixels, or 8.29 megapixels.
This means that a 4k still frame is equivalent to 8.3 megapixels.
It’s worth noting that many consumer electronics brands like Sony advertise their cameras as being ‘4k capable’ for still images. While this may be true, 8.3 megapixels is relatively low when compared to other digital cameras on the market.
So What’s Ultra HD?
‘Ultra High Definition’ is used interchangeably with the term ‘4k.’ When encountering both of these terms while shopping, it helps to know that they’re one and the same. Just be sure to double-check the aspect ratio and ‘version’ of 4K you’re dealing with.
It will either be 3840 x 2160 pixels or 4096 x 2160 pixels. Both can work wonders, but the latter offers a bit more bang for your buck.
4K VS 1080p
So what’s the difference between 4K and 1080p? When picking up a 4K TV or shopping for computer monitors, for example, is it really worth spending more for the higher resolution?
For smaller phone and laptop screens, perhaps not. Otherwise, the difference can be remarkable.
In terms of pixel resolution, 4k is four times the resolution than 1080p.
4k is also twice the line resolution of 1080p. The same is true of horizontal resolution.
In short, you’re dealing with way more pixels and a much clearer image overall.
It is worth remembering, though, that on smaller screens this difference can be harder to spot. If you’re just shopping for a small-screen laptop, you may be better off saving money on a lower resolution screen – your battery life and wallet may thank you!
A Home Theater Tip – High Dynamic Range
It’s natural to want the ‘best possible’ resolution for your home theater setup. The thing is, the resolution of your screen is just one factor to consider. Something that can make a huge difference to your viewing experience is picking up a TV that offers a high dynamic range.
In short, HDR is all about improving the contrast between the brightest brights and the darkest darks. In a well-calibrated TV, you’ll be able to appreciate the full color spectrum and take in each movie, TV show, or documentary in all its glory.
If a TV offers a slightly lower resolution but has impeccable HDR features, it’s definitely worth a second look in our opinion.
This is also worth considering when shopping for a new computer screen. Just remember that the refresh rate and latency, you may need can change depending on what you’re doing on your computer. If you’re gaming, definitely look for low-latency, high refresh rate options.
How do I Calculate the Number of Pixels?
Scratching your head wondering how many megapixels are in a certain ratio or resolution? Megapixel calculators like this one can be super useful. Just enter the height and width of a given frame and you’ll get back the following data:
- The number of pixels in the still frame
- The number of megapixels this equals
This can provide a great shortcut the next time you’re asking this kind of question!
Do I Need a Camera With Lots of Megapixels?

The number of pixels in each photo that your camera produces is just one small part of a larger picture (pun intended!). You could be pushing fifty million pixels and still end up with a disappointing final result.
Why? Because the height and width of each frame isn’t the whole story.
A much more important factor to consider is the sensor size of the equipment you’re using. In general, a larger camera sensor allows for significantly more light to enter your device. It also leaves more space for smarter autofocus features and faster image processing.
The specific lens you choose is another huge hurdle to navigate. Choose the right lens and your photography sessions can become effortless. Use lacklustre equipment and your images can suffer.
In short, MP is a relevant piece of the puzzle, but they pale in significance when compared to sensor size and your camera’s lens.
