Image size refers to the physical dimensions or resolution of a picture measured in pixels (such as 1920 × 1080 px), while file size is the amount of digital storage space that the image data consumes on a hard drive or memory card, measured in kilobytes (KB) or megabytes (MB). Think of image size as the actual physical dimensions of a blank canvas, and file size as the weight of the canvas once you add paint, textures, and framing.

Image size dictates how large your image looks on a screen or how big it can cleanly print.
Pixel Dimensions: A standard high-definition image has an image size of 1920 × 1080 pixels, totaling roughly 2 million pixels (2 Megapixels).
Print Resolution: When printing, image size pairs with DPI (dots per inch) or PPI (pixels per inch) to determine physical output clarity. For instance, a larger pixel dimension allows you to print a large, high-quality photo without blurriness.
Social Layouts: Platforms like Instagram require specific image dimensions (like 1080 × 1080 px) to prevent awkward cropping. Understanding File Size
File size measures the data weight of the file. It directly impacts how fast a webpage loads or how many pictures fit onto your device.
