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 otherhand, a 72 dpi file might make a good wall size mural. The only "true" measure of resolution is the "pixel resolution", which is expressed in pixels as length by width.
On most computers, you can determine the pixel resolution by "hovering" the curser over the file name or by right clicking and selecting "file info" or "properties". With some file types you may have to open it in an imaging program like PhotoShop, or Gimp to see the pixel dimensions of your file. It will read something like 3000px X 4500px. 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 300 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. 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 files 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.
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.
