Introduction
Photography can be something of great passion and dedication. Many factors determine how your photo will come out. The megapixel count is one of them. A very frequent concern is how much megapixel is good and why.
So, what about 18 megapixels vs. 24 megapixels?
Twenty-four megapixels generate a larger image than 18 megapixels. As a result, the optimal printing size of 24 megapixels is significantly bigger than 18 megapixels. More megapixel also means more noise, so 24 megapixels can be noisier than 18 megapixels. Lastly, 24 megapixels consume more space.

18 Megapixel vs. 24 Megapixel-A Short Comparison
The difference between 18 and 24 megapixels is very insignificant in most cases. But it can matter a lot to a photographer or in a specific situation. The core difference in different megapixels is the number of pixels present in the photo.
The higher the pixel number, the better. Now, let’s check out the differentiating factors of 18 vs. 24 megapixels. Below is a short table comparing these two.
| Parameter | 18 Megapixel | 24 Megapixel |
| Pixels (Wide x High) | 5184×3456 | 6000×4000 |
| Optimal Printing Size | Upto 12″ x 16″ | Upto 20″ x 30″ |
| Noise | Less | More |
| Raw File Size | Around 25 mb | Around 48 mb |
So these are the key differences between 18 megapixels and 24 megapixels. Need more information? Don’t you worry! Because we have a complete guide on the differences mentioned here.

18 Megapixel vs. 24 Megapixel-Detailed Comparison
As we have briefly discussed the key differences, we’ll discuss them in detail now.
Pixels (Wide x High)
Typically we have an idea that more megapixels mean better quality. But in reality, that is not the case. More pixels mean there will be more pixels in the photo. As a result, the image will be larger.
So a higher megapixel will generate a bigger image. The 18-megapixel has a width of 5184 pixels and a height of 3456 pixels.
On the other hand, 24 megapixels have a width of 6000 pixels. And a height of 4000 pixels. So as obvious as it is, 24 megapixels is larger. You may also check out comparisons of Zwo cameras for a better idea.
It also means that a 24-megapixel will give better quality photos if cropped in. Since it has more pixels, the photo’s cut will not get pixelated. At the same time, an 18-megapixel image can get pixelated relatively earlier.
So if you intend to have a bigger printout, then 24 megapixels is better. But for general use, 18 megapixels can be fine too.
Winner: 24-megapixel
Optimal Printing Size
We have already talked about how the number of pixels can be significant. It’s more prominent in terms of getting printouts. A higher megapixel will be better for printing a larger photo. At the same time, a lower megapixel might cause issues. Such as pixelated or blurry images can be some of them.
A 24-megapixel photo can be printed in a size of upto 20″ x 30″. The image won’t get blurred or lose detail if printed out in this size. On the other hand, an 18-megapixel photo will get pixelated at this size.
Though you can try some hacks to prevent distortion or pixelation of your image.
An 18-megapixel photo supports upto 12″ x 16″ size of a printout. This is the optimal size for a printout so that it won’t lose detail or get distorted after the printout.
A 24-megapixel will have an edge if we consider printing out. If you intend to print a large poster, then 24 megapixels will be better. But, for regular use, smaller screen, or prints, 18 megapixels is fine.
Winner: 24-megapixel
Noise
Noise is a very important factor in any photography. But especially for astrography, noise plays a very significant part. Since a higher megapixel means higher pixels, it can also be disadvantageous.
As a result, it captures more noise than a camera with a lesser megapixel. This is why most astrography cameras have a low megapixel.
So 18 megapixels can be a better option if you intend to do astrography. On the other hand, 24 megapixels can also be good if you have the right equipment.
Are you thinking of using your camera with a telescope? You can take a look at their aperture comparison for better-quality photographs.
The photo quality depends more on the lens and camera quality than the megapixel. So if you have good gear, then 24 megapixels can also do the job.
In case you’re looking for some good gear for astrography, here are some recommended ones:
But assuming everything is the same, an 18-megapixel camera does have an edge. It can produce a less noisy photo when capturing the night.
Winner: 18 Megapixel
Raw File Size
It’s quite obvious that more pixels will lead to a bigger raw image size. An 18-megapixel photo typically consumes 25 MB of space. On the other hand, a 24-megapixel image can consume around 48 MB.
The great difference in size for each file can add up. And later lead to higher requirements for space in your storage. This can be quite inconvenient in many cases. It can be problematic if you don’t need higher pixels and lack storage space.
But the differences mentioned above do make up for the larger file size. Still, 18 megapixels stay ahead in terms of space consumption.
Winner: 18 Megapixel.
Final Verdict
So, 18 and 24 megapixels are quite similar in many things. Even though they are very close, there are some significant differences.
Twenty-four megapixels means it will have more pixels so that you can have a larger photo. It will support a larger printable image without image distortion or pixelation. But it will also create larger raw files and might be noisier in certain cases. So if those are not a concern for you, then 24 megapixels is the way to go.
On the other hand, 18 megapixels will give you a smaller image relative to 24 megapixels. It will consume less space in and for astrography. Plus it’ll have less noise. It’s also good enough to be seen on small screens without worry. So consider factors and then decide if 18 megapixels is good for you.
FAQs
Question: How much megapixel is good for a phone camera?
Answer: Anything equal to or more than 12 megapixels is good enough. For viewing on the phone screen, 12 megapixels is more than enough.
Question: Do more megapixels mean better quality?
Answer: No, the megapixel only represents the image size you will capture. Image quality significantly depends on the sensor quality.
Question: How many megapixels does a DSLR camera have?
Answer: A DSLR camera typically has a megapixel of 25 megapixels. A higher megapixel is often needed for professional photography.
Conclusion
That’s a wrap for this guide. We hope you are not confused regarding 18 megapixels vs. 24 megapixels.
And remember that a megapixel is just a representation of your image size. The image quality depends on many other factors rather than the megapixel alone.
Good luck, and see you at the next one!
