|How to specify picture size|
|If you know the area you want to have a picture fill and the process (commercial print, exhibition print etc) and need to tell your picture supplier the minimum size the image must be to meet that need, use the calculator below. Complete the height and width in millimetres. The calculator will give you the minimum pixel size for the image for the following resolutions:
72 to 75 dpi screen use*, desktop inkjet print, large format inkjet exhibition print (final size on the display print).
300 dpi commercial printing of leaflets, brochures etc.
*Note: for screen use, web pages etc, sizes are defined by pixels anyway as the monitor works in pixels, not mm or inches. The size appearing on screen depends on what you have your monitor set to show as a full screen (e.g. 800 x 600 pixels, 1024 x 768 pixels, 1280 x 1024 pixels etc).
The calculator will show the minimum number of pixels for height and width. More pixels are not a problem (the more pixels, the more data in the image file), so having more pixels than specifed by the calculator is good.
|Enter height and width in millimetres.|
|Up to 10% fewer pixels under the calculator result is not going to be a big issue, but fewer than that means an increasingly poor print result to the point of looking bad for your company.|
