What resolution should my photos be?
We print at 300 dpi, and recommend that your images be as close to 300 ppi as possible if you are looking for the absolutely sharpest prints.
What is the minimum size photo I can order?
For most products our minimum file size is set at the 100ppi size. For example, if the print is 8x10, our minimum file size we can accept is 800x1000 pixels.
We have more in depth information and tips on file size on our blog post here.
My photo is definitely big enough, how will I know it will print well?
Our processor blocks photos that are too small, but cannot see things like resolution or lighting. (It is a very farsighted robot). A good way to tell if your photo will print great on a larger scale is to check the resolution. We print at 300 dpi, you want to be as close to this as possible. If you are still nervous, you can perform what we call the "zoom test" on your image prior to upload. Open up your photo on your computer's photo viewer, and zoom in a little bit. If you are seeing pixelation when you zoom, this will also show up in print.
As a general rule, we recommend printing photos that are taken in natural light. Indoor photos at low light can look fuzzy. (Sorry bar selfies!)
I am getting "Low Resolution" warnings, why?
We have size requirements for all of our prints to ensure that your photos print well. We have these set at 100ppi, so for example if you are ordering an 8x10" print, the image file must be at least 800x1000 pixels in size. We have more information about how large you can print your photos here.
If you are worried about a particular photo, we can help! Send us the photo along with the product/size you are looking to print it to hello@sps.io and we will give you frank assessment.
