![]() ![]() So, on a 16GB SD card that results in around 3,150 photos. For the sake of convenience, let’s take the middle point of 5.2MB. While shooting with the smartphone, we found that the average JPEG image size works out to anywhere between 3.5MB to 7MB, depending on the lighting and what’s in the shot. Note that these results apply to all types of memory cards, be it SD, Micro SD, CompactFlash etc. And finally, for the GoPro camera, we used the GoPro Hero 9 Black, but set on 12MP, which is the most commonly used resolution. For the DSLR, we considered pictures taken with a Nikon D7200 and averaged out the sizes of multiple pictures (in both JPEG and RAW file formats). So, for smartphones, we used the most common image resolution, which is 12MP. Now, each of these devices has a multitude of variants with each offering a plethora of settings that you can change. To simplify things, we considered the three most common devices that you’re likely to use a memory card to store photos in – a smartphone, DSLR, and a GoPro. Not to forget, the device you’re shooting on will also play a part. How did we calculate how many photos each SD card can hold?Īs you can see, it can be quite complicated to tell exactly how many images an SD card can save because of how many factors are involved. That comes down to the way the JPEG compression algorithm works by identifying similar areas in the picture. Similarly, taking a JPEG photo of a white wall will result in a smaller file size than, say, a scene in a busy city. Images with a higher ISO typically take up more space. ![]() Settings like the ISO and shutter speed can also affect the size of an image. Select cameras can also shoot in sRAW and mRAW which are a middle-point between RAW files and JPEGs. It’s also worth noting that DSLRs also offer multiple quality options under JPEG, like an extra-fine, fine, and standard, based on which file size will vary. These images are compressed, meaning the file size is smaller, but the image quality is reduced. JPEG is the most common image file format. Images stored in the RAW format will take up significantly more space as this format saves as much data as possible. For example, in professional photography you’ll almost always be shooting in RAW. Most digital cameras have different shooting modes that you can choose between. The more pixels there are in an image, the higher quality it becomes – but this also means it will take up more space. The image resolution describes how many pixels fit in each inch horizontally and vertically on your screen. Most notably, there’s the image resolution (pixels), compression settings, and even the shooting conditions. Several factors determine how large a photo will be. In this article, we’re going to cover how much space each of these options offers in comparison to one another so that you can make an informed decision about which size suits your requirements best.īut, before we do so, it’s crucial to know the different factors which determine how much space any given photo will take up. ![]() The five common camera memory card capacities on offer are 16GB, 32GB, 64GB, 128GB, and 256GB. How many pictures can your SD card hold? Knowing the answer to this question could be the difference between having the ability to shoot all you need and having to make hard choices about which photos are worth keeping. ![]()
