Pixel to Print Resolution
The resolution of your digital file needs be large enough to support the print size that you want. The chart below will allow you to determine the pixel resolution required for various print sizes. Many people think of resolution as dpi, which ironically is not very accurate; a file can be 1000 dpi and only be capable of providing only modest sized print, while on the other hand, a 72 dpi file might make a good wall size mural. The only “true” measure of resolution is the “pixel resolution”, which is expressed as the number of pixels in the length and the width of an image.
On most computers, you can determine the pixel resolution by “hovering” the cursor over the file name or by right clicking and selecting “file info” or “properties”. With some file types you may have to open the image in a program like Photo Shop, Paint or Gimp to see the pixel dimensions of your file. It will read something like 3000 pixels X 4500 pixels. This description can be converted to various sizes at different output resolutions (see the chart below).
All of our photo and inkjet printing is normally produced at between 200 and 360 dpi output size, but because of limits in camera sensor resolution, producing large print sizes may require special processing to make prints of optimum quality. We use special software and processing that will optimize your file for maximum quality. In some cases improperly re-sizing the file can actually decrease the quality of the final print, so please allow us to handle this if needed. Should your file’s pixel resolution appear in, or is lower than that specified in the “pink” column below for the print size you desire, please check with us before ordering.
We have not included file sizes in the cart below because of the exceptionally wide size variation a file may have due file type (Jpeg vs. Tif) and/or Jpeg quality setting.
