What Is A Normal Photo Size

By | 25/11/2022

When taking pictures with our phones, most of us don’t fifty-fifty think nigh the actual size of the photos we’re taking. That is until the phone warns the states we’re running out of retentiveness. Simply then we worry well-nigh how much space our photos occupy.

How big are mobile photos?

The size of a photo depends on many factors but mainly the sensor and number of megapixels it has.

The more megapixels, the larger the resolution and, ultimately, the larger you can impress the image in photo quality. More than resolution also means a bigger file size.

All the same, two images with the same resolution can accept different file sizes depending on the format and contents of the picture.

What affects the file size of smartphone photos?

Unless it’s the exact same shot, no ii images captured by the same camera are ever the same file size. This could be because of the contents of the photo or the settings of the photographic camera.

At the very core of what affects the size of mobile photos is the design and specs of the camera, specially the sensor and the number of megapixels on it.

i. Megapixels

The term ‘megapixels’ refers to one meg pixels. These pixels are private squares that make up an image.

For example, a 12MP epitome is made up of 12 million pixels. The higher the megapixel count, the more detailed the image is. This not only ways a bigger file size, simply as well a larger physical print. More than on this later.

Here’s basically what this means: A 12MP epitome has a resolution of about 4000 x 3000 pixels in width and height. This would give you a photo-quality print of approximately 13″x10” and an approximate jpeg file size of ~3MB.

Continue reading below to find how I got to those figures.

2. The sensor

Megapixels aren’t the “be-all and end-all” of the factors that touch on file size. The size of the sensor also plays a office because it determines how many pixels the sensor can suit, and how large the pixels can be.

A big sensor with large pixels can receive a lot more light data than a minor sensor with tiny pixels. All that information captured by the sensor means more space will be required.

iii. The detail

The corporeality of item that is in the picture adds to the overall file size. If you accept a photo in a low-light surround or against nothing but a solid colour, there isn’t much low-cal information or colour variation in the shot. And so, the resulting file size will exist pocket-size.

On the other hand, bright pictures with a lot of color and intricate particular volition definitely yield larger file sizes. This is considering in that location’s a lot more low-cal information of varying intensities coming through that needs to be processed.

iv. The file format

Non all smartphones have back up for more than than 1 file format for photos other than jpeg. All the same, some phones give you an selection to either shoot jpeg or RAW. If yous choose to shoot RAW, then the file size of your photos will be significantly larger.

Jpeg vs RAW file size

These two file formats take their ain distinct qualities that bear upon the file size (non resolution).

Equally previously mentioned, jpeg is the most popular format that is used in pretty much every camera telephone on the market place. When your smartphone is set up to salvage in jpeg (or jpg) format, the image is automatically processed and compressed to an optimum size and tosses out whatsoever extra information. The result is a very decent, optimised, high-quality picture with a small file size.

RAW (DNG) files are every bit the proper noun suggests

raw. These type of files are quite large and bulky because, different with jpeg, they aren’t automatically candy. Therefore, they remain uncompressed and retain all the picture information that a jpeg file would’ve otherwise stripped away. This allows for more flexibility in post-processing.

Because it is uncompressed and unprocessed, a RAW file can exist roughly three times or more than the size of a jpeg. For example, if an average photo taken with a 12MP smartphone photographic camera is ~3MB (megabytes) in jpeg format, it is possible that the same motion picture in RAW format could exist equally large as ~19MB.

The folks at Toolstud.io have a very handy

megapixel reckoner

you tin utilize to give you a rough idea of how large in megabytes (MB) a photograph tin can be given its resolution from calculating its megapixels (MP) and file format.


Is in that location a way to reduce the MB size of a photo without losing quality?

An like shooting fish in a barrel way to chop-chop and hands reduce the file size or even resolution of a moving picture is to utilise a tertiary-party app like

Photograph & Moving-picture show Resizer
 for Android.

This app allows you lot to easily reduce photo size without whatever apparent loss of quality. You can utilise information technology before uploading your images online or sending loved ones your photos via email or text. It’south convenient and super simple to utilise.


available on iPhone does pretty much the same function. Not just does it easily resize photos, but it too does the same for videos besides.

It can output images in a diversity of formats for both photos and videos without a hassle. What’due south more, it allows batch resizing, which I call up is pretty cool.

If your pictures are on your estimator and you would similar to resize them from there, a quick Google search for online picture resizing volition give you endless options of sites where you tin can upload your picture and have it automatically resized or enter your own specifications.


is a good example of such a site.

Messenger apps such equally WhatsApp and email clients similar Gmail are known to shrink images that are sent via their platform.

The loss of quality on the resized photo is not and so credible on the phone screen but you won’t become every bit big a impress from it as you lot would have from the original photograph.

How large can you lot print your photos?

Many factors influence how large you lot can print your smartphone photos but the main one is the actual resolution of the photos. The higher the resolution, the larger the print.

To find what size you lot can print a photo, y’all need to divide each dimension of the resolution past the PPI (pixel per inch) quality you lot wish to print. 300ppi gives y’all photo-quality prints while 200ppi can still requite you lot skilful quality.

Anything 150 and beneath is low quality and may brand the pixels visible when looking at the images.

For example, a smartphone with a 12MP resolution camera will produce a print of 14” 10 ix” at 300ppi, 21” ten fourteen” at 200ppi, and 26” x 16” at 150ppi.

Keep in listen that as much as printing at 150ppi allows you to print larger pictures, the photos aren’t as precipitous as they would be if they were printed smaller at 300ppi.

It’s important to sympathize PPI (pixels per inch) and not confuse it with DPI (dots per inch), specially if you lot’re looking to

impress your own photos from home

Information technology’south worth noting that cropping and editing your photos with some third-party apps such as Instagram may affect the size and resolution of your photo.

I recommend using pro-level apps and software to

shoot and edit

your photos and retain their original size.

So, does size matter?

I’d say it does, depending on your needs. If you’re a serious smartphone lensman who sells prints of their work, and then you’d probably want to shoot RAW at a college resolution. If that’southward the case, expect large file sizes.

But if y’all’re the average Joe then you don’t really need to shoot RAW. You don’t fifty-fifty demand to shoot at a loftier resolution. An 8MP. jpeg is more than enough to mail service on social media or text to friends and family.

And at an estimated file size of about 2MB, yous will have even more infinite on your device.
