What makes up the size of an image?

If you don’t completely understand why image size is so important, read on. The average person won’t know this as it does get a little technical at times, but that is what we are here for.

Image size is measured in pixels. It is not measured in inches or centimeters, so it cannot be calculated with the naked eye or even a ruler. A pixel is a tiny digital package of information that is displayed as a dot of color. A whole lot of pixels combined make up an image.

The camera and the settings used to take a photograph determines the size of the image created. Some photographers prefer to use larger image sizes while others prefer smaller ones. It all depends on what the images are intended to be used for.

A huge benefit to smaller image sizes is that more images can be stored on the same amount of storage space. For most people, large images are not necessary and take up unnecessary space on their SD cards or hard disk drives.

Keep in mind, however, that large image files are necessary if you plan to use the pictures for commercial purposes. Examples of these would be large-scale advertisements or billboards.

Remember that an image needs to be stretched in order to cover a large surface area. If the image size is not sufficient for this purpose, then the quality would be compromised and the resulting image would look bad.

In the digital age that we are in today, many images are created electronically on computers or other devices. In this case, the user can select which image size he or she would like to export the image as once the creation process is complete.

This is important because an image can only be compressed in size, it cannot be made larger.
