Pixel dimensions
Dimensions describe width and height in pixels, such as 1920 × 1080. Multiplying those numbers gives the total number of pixels in the image.
File size
File size is the amount of storage the image uses, measured in KB or MB. Dimensions, format, visual complexity, transparency, and compression all influence it.
Common dimensions
| Size | Ratio |
|---|---|
| 1920 × 1080 | 16:9 |
| 1280 × 720 | 16:9 |
| 1080 × 1080 | 1:1 |
| 800 × 600 | 4:3 |
Resolution and print
For screens, pixel dimensions are usually the practical measurement. Printing also depends on physical size and pixel density. A file that looks large on a screen may not contain enough pixels for a large, sharp print.
