What we see when we view an image on screen or in print will always reflect the qualities of the output device as much as the original digital image. Different output sizes and different output devices will both affect the required resolution and therefore the created file sizes. Examples of output device would include a laser printer, a printing press or a computer monitor. A resolution should be chosen that provides a file that is ‘good enough’ for all anticipated uses to which the file is likely to be required for, but no more.
- For images in PowerPoint: 150 DPI
- For print images: 300 DPI
- For images on websites 72 DPI
- For images in Word /PDF documents to be viewed on screen: 96 DPI
Note: Higher resolution image files will increase the overall file size of your thesis.
