Memory Card Capacity


One of the most asked questions we hear in our shops is “How many pictures can I get on my memory card”?

The honest and most truthful answer is...we don't know.

I know that doesn't help, but let us explain why.

With increasing resolutions of cameras, the capacity of a single type of memory card is changing just as fast.

It also depends on how each camera will compress and store the file.

The two most popular files for taking photos is JPEG and RAW.  Some cameras will allow you to take both types at the same time.

This will decrease the amount of space available on your card.

We've come up with this chart to give you a rough idea...

MP = 1,000,000 pixels
1MB = 1,000,000 bytes, 1GB = 1,000MB
TIFF image has 24 bit color depth, one of 16,777,216 colors per pixel
JPEG 100% Quality = Visually lossless JPEG compression with 1:10 ratio of RAW image

Photos - Compressed (JPEG 100% quality) Images per card.

This is only a guide.  It is not going to be perfect every single time.

You will need to check with the manufacturers of the cards and the camera to get a perfect number.

In terms of how much video would you get on your card, this poses a new set of questions, particuarly in terms of what compression rate, video file format and which level of definition you are recording.

However, what we have discovered is that...


*1GB = 1 Billion Bytes

**Approximations: results will vary based on file size, resolution, compression, bit rate, content, host device, pre-loaded files and other factors.

But for brands such as GoPro, it changes again as they offer 4K Movie quality.
