How many photos fit in a gigabyte?
The short answer is: it depends on what kind of files you shoot.
One GB usually holds about:
- a few hundred JPEG photos
- a few dozen RAW photos
As you can see, if you shoot JPEG, a gigabyte can hold a surprisingly large number of photos. But if you shoot RAW, that same gigabyte fills up a lot faster.
That’s why the most useful answer isn’t one fixed number. It’s a quick estimate, plus a simple way to understand how your own files affect storage.
Here are estimates for how many photos 1GB, 32GB, 64GB, 128GB, 256GB, and 1TB can hold:
| Storage Size | JPEG (3–8 MB) | RAW (20–50 MB) |
|---|---|---|
| 1GB | 128 to 341 | 20 to 51 |
| 32GB | 4,096 to 10,912 | 640 to 1,632 |
| 64GB | 8,192 to 21,824 | 1,280 to 3,264 |
| 128GB | 16,384 to 43,648 | 2,560 to 6,528 |
| 256GB | 32,768 to 87,296 | 5,120 to 13,056 |
| 1TB | 131,072 to 349,000+ | 20,000 to 52,000+ |

How Many Photos Per GB? A Quick Answer
As we covered above, there’s no one universal answer to the number of photos per GB because photo file sizes vary a lot.
But as a practical starting point, a gigabyte will usually hold a few hundred JPEG photos or a few dozen RAW photos.
The big difference is file size:
- JPEG files are compressed, which keeps them relatively small.
- RAW files preserve a lot more image data, which makes them significantly larger.
Here’s a quick side-by-side:
| File Type | Typical File Size | Estimated Photos Per GB |
|---|---|---|
| JPEG | 3 MB to 8 MB | 128 to 341 photos |
| RAW | 20 MB to 50 MB | 20 to 51 photos |
That range is normal.
A smaller JPEG from a phone or lower-resolution camera takes up less space than a high-resolution file from a modern body. RAW files vary even more depending on resolution and format.
So if you just need the quick answer, this is the takeaway: JPEG takes up a lot less space than RAW.
Or, to put this in storage terms, RAW will fill storage a lot faster than JPEG.
Below, you’ll see estimates for how many photos you can hold at 1GB, 32GB, 64GB, 128GB, 256GB, and 1TB so you can quickly compare common storage sizes and understand how capacity scales.
How to Calculate Photos Per GB
Once you know your average file size, estimating storage becomes straightforward.
The real question isn’t “How many photos fit in a gigabyte?”
It’s “How large is each photo file I’m creating?”
Once you know that, the math is simple.
Here’s what that calculation looks like in its simplest form:
And here’s the formula:
| Step | What to Do |
|---|---|
| 1 | Find your average photo file size in MB |
| 2 | Divide 1,024 by that number |
| 3 | The result is your estimated photos per GB |
For example, if your JPEG files average 5 MB, 1,024 ÷ 5 gives you about 204 photos per GB.
If your RAW files average 30 MB, 1,024 ÷ 30 gives you about 34 photos per GB.
Here is what that looks like across a few common file sizes:
| Average File Size | Estimated Photos Per GB |
|---|---|
| 3 MB | About 341 photos |
| 5 MB | About 204 photos |
| 10 MB | About 102 photos |
| 20 MB | About 51 photos |
| 30 MB | About 34 photos |
| 40 MB | About 25 photos |
This is the logic behind every storage chart.
Once you understand it, you can adjust the estimate to match your own camera instead of relying on generic numbers.
That matters because broad averages are useful, but they’re still averages.
A practical estimate based on your own files will always be more helpful than a generic chart built around someone else’s camera and settings.
What Affects How Many Photos Fit in a GB
If you’ve ever seen different storage charts with slightly different answers, this is why:
The number of photos per gigabyte depends on the size of the files you are creating.
That is, the storage size stays the same. Only the file size changes.
File Type: JPEG vs RAW
This is the biggest factor.
JPEG files are compressed, which makes them a lot smaller. That’s why you can store hundreds of JPEGs in a single gigabyte.
RAW files are much larger because they keep more image data.
That extra data is useful for editing, but it reduces how many photos fit in the same space.
Two photographers using the same card size can end up with completely different storage limits depending on this one choice.
Megapixels and Resolution
Higher-resolution cameras generally produce larger files.
A 12MP image takes up less space than a 24MP image, and a 24MP image usually takes up less space than a 45MP file.
This is why generic charts can feel inconsistent.
A chart based on smaller files may be technically correct, but not very helpful if you’re shooting on a higher-resolution camera.
Compression, Settings, and Scene Detail
File sizes aren’t perfectly fixed.
JPEG size can change depending on compression settings and how much detail is in the image.
RAW files can vary based on camera brand and whether you are using compressed or uncompressed formats.
That means even within the same shoot, file sizes can move around. Two files from the same camera, on the same day, may not be identical in size.
The Most Reliable Way to Estimate Your Own Number
If you want the most accurate estimate, use your own files.
Take a sample from a recent shoot, check the file sizes, and calculate the average. Doing that will give you a much more reliable number than any generic chart.
This matters more once you’re shooting regularly or doing paid work.
At that point, small differences in file size can add up quickly over a full shoot.
Real-World Examples— What This Looks Like in Practice
Numbers are nice, but they become a lot more useful when you see how they play out in real shooting situations.
A storage chart can tell you how many files might fit. But it can’t tell you how that feels during an actual day of shooting.
Casual Shooting (JPEG)
If you’re shooting JPEG, storage usually feels generous.
- You can shoot hundreds of photos without thinking much about space.
- A 32GB or 64GB card often lasts a long time.
- You are unlikely to hit limits unless you shoot heavily or rarely clear cards.
For everyday shooting, the smaller file sizes do most of the work for you. That’s why casual photographers can often go a long time without thinking much about storage at all.
Travel or Hobby Shooting (JPEG + Some RAW)
This is where things become less predictable.
- Most photos are still relatively small, but some are much larger.
- A 64GB card can still work well, but fills faster on heavier days.
- A 128GB card gives you more breathing room and fewer surprises.
This kind of mixed workflow is where people often start noticing that storage estimates are not as simple as they first looked.
Event or Wedding Shooting (RAW)
Storage planning really matters in these scenarios. I shoot weddings for a living, and I’ve learned this the hard way.
- RAW files fill cards quickly, especially on modern cameras.
- A 64GB card can disappear faster than expected.
- 128GB or 256GB is usually a safer baseline for higher-volume work.
In my experience, this is where photographers get caught off guard.
You should always have extra cards in your bag in case the ones you are using fill up. I normally use a 128 gb on each of my two cameras, but on really long days (10-12h) those can fill up if there’s a lot happening.
Storage feels fine when you are shooting casually. But during a full wedding day—taking bursts, covering multiple parts of the day, and not deleting anything—it adds up fast.
What feels like plenty of space in the morning can disappear by the reception if you’re not paying attention.
How Much Storage You Actually Need
So how much storage do you actually need?
The answer depends on two things:
- how heavily you shoot
- how much margin you want
Some photographers are comfortable managing smaller cards.
Others would rather have enough backup that storage never becomes a problem they have to think about

Here’s a quick way to think about it:
| Shooting Style | File Type | Recommended Storage | Why |
|---|---|---|---|
| Casual | JPEG | 32GB to 64GB | Small files and moderate volume |
| Hobby / Travel | JPEG + RAW | 64GB to 128GB | Mixed file sizes create uneven usage |
| Events / Weddings | RAW | 128GB to 256GB+ | Large files and high volume |
No surprise: the more you shoot and the larger your files are, the more storage you need.
In practice, it’s usually better to plan for more storage than you think you need. Running out of space mid-shoot is easy to avoid and frustrating when it happens.
A slightly larger card usually costs much less than the stress of managing storage during an important moment.
Photo Storage Cheat Sheet—All Sizes
The estimates in the intro depend on file size.
A 5MB JPEG takes far less space than a full-resolution RAW file, so two photographers using cards with the same capacity can end up with very different numbers of photos.
The basic relationship is simple: doubling the available storage lets you save approximately twice as many files of the same average size.
But the number of photos a card holds also depends on the camera. Higher-resolution cameras generally produce larger RAW files, while compression settings can make files from the same camera considerably larger or smaller.
How Many RAW Photos Fit on a Card for Popular Cameras?
The same memory card can hold very different numbers of RAW photos depending on the camera and the RAW setting you choose.
The comparison below uses one clearly identified, full-resolution RAW setting for each camera. These are planning estimates rather than guaranteed capacities. Actual totals can vary with RAW compression, image content, camera settings, firmware, and the card’s formatted capacity.
| Camera | RAW Setting Used | 64GB | 128GB | 256GB |
|---|---|---|---|---|
| Nikon Z6 | 14-bit lossless-compressed NEF | About 1,100 | About 2,200 | About 4,400 |
| Nikon Z8 | Lossless-compressed NEF | About 700 | About 1,400 | About 2,800 |
| Canon EOS R5 | Full-resolution RAW | About 1,300 | About 2,700 | About 5,400 |
| Canon EOS R6 | Full-resolution RAW | About 2,800 | About 5,600 | About 11,200 |
| Canon EOS R7 | Full-resolution RAW | About 1,700 | About 3,500 | About 7,000 |
| Sony α7 V | Full-resolution compressed RAW | About 1,900 | About 3,800 | About 7,600 |
| Sony α7R VI | Full-resolution compressed RAW | About 930 | About 1,800 | About 3,600 |
| Sony α9 | Full-resolution compressed RAW | About 2,400 | About 4,800 | About 9,600 |
How these estimates were calculated: The figures are based on manufacturer-published memory-card estimates for the listed RAW settings, scaled to comparable card capacities and rounded where appropriate.
Use these figures as a starting point. After formatting a card in your camera, check the remaining-image estimate displayed by the camera before an important shoot.
How Many Photos Can 64GB Hold?
A 64GB card can hold hundreds or thousands of photos, depending on the camera, file type, and image-quality settings.
If you shoot JPEG, you can expect roughly 8,000 to 21,000+ photos. For RAW, a broader planning range is about 700 to 3,200+ photos.
That’s why 64GB can feel generous for casual JPEG shooting but much tighter with large RAW files. For many hobbyists, it’s still plenty. For events or full-day RAW shoots, it may feel less comfortable.
How Many Photos Can 128GB Hold?
A 128GB card gives you significantly more breathing room.
If you shoot JPEG, it can hold roughly 16,000 to 43,000+ photos. For RAW, expect approximately 1,400 to 6,500+ photos, depending on the camera and RAW setting.
In practical terms, 128GB is where storage usually starts to feel comfortable rather than limiting.
For hobby shooting, it gives you plenty of headroom. For weddings, events, or other higher-volume work, it’s often a safer baseline than 64GB.
How Many Photos Can 256GB Hold?
A 256GB card pushes that margin even further.
If you shoot JPEG, it can hold roughly 32,000 to 87,000+ photos. For RAW, a reasonable planning range is approximately 2,800 to 13,000+ photos.
That doesn’t mean everyone needs a 256GB card.
But for photographers who shoot a lot, work in RAW, or simply want more buffer during long sessions, 256GB can make storage feel much less restrictive.
Photo Storage FAQ
Here are answers to some of the questions I see come up a lot around storage and how many photos go on different sizes of gigabytes.
How many photos are there per GB on an iPhone?
Most iPhone photos are roughly 2 MB to 5 MB, so a gigabyte will usually hold a few hundred photos. The exact number depends on your camera settings, image format, and whether features like Live Photos are turned on.
How many RAW photos fit in a GB?
Most RAW files fall somewhere around 20 MB to 50 MB, which means a gigabyte usually holds about 20 to 50 RAW photos. Higher-resolution cameras and larger RAW formats push that number lower.
Is 128GB enough for photography?
For many photographers, yes. It is a comfortable baseline for hobby shooting and often enough for a full day of work. For high-volume RAW shooting, especially events or weddings, larger cards or multiple cards give you more margin.
Why do different charts show different numbers?
Because file sizes vary. Camera resolution, file format, compression settings, and even the amount of detail in the scene can all change how large each photo file is.
Is it better to use one large card or multiple smaller ones?
That depends on your workflow. One large card is simpler, but multiple smaller cards reduce risk if a card fails or gets corrupted. Many photographers prefer splitting storage for that reason.
How many photos can a 64GB card hold in RAW vs JPEG?
A 64GB card can often hold roughly 8,000 to 21,000+ JPEGs or about 1,200 to 3,200+ RAW files. The real number depends on your camera and average file size.
How can I find my camera’s actual file size?
The easiest way is to look at a recent batch of images from your camera and check the file sizes on your computer or phone. Use a small sample from a real shoot, calculate the average, and you will get a much more useful estimate than a generic chart.
Does shooting style affect how many photos fit on a card?
Yes. If you shoot in bursts, keep everything, or work in RAW all day, your storage fills faster. If you shoot lightly in JPEG and cull often, the same card will stretch much further.
