Have you added multiple products to your Pixieset Price Sheet, but when your clients go to your Store to purchase images, only a select few of the smaller items are listed for purchase? 

If your clients are not seeing the full list of products for purchase, this means that your uploaded files do not meet the minimum resolution requirements for the missing print products. When your images do not meet the minimum resolution requirements for certain product sizes with Lab Fulfillment, Pixieset will only let your clients purchase the product sizes that your files are suitable for. 

If you want to offer the larger prints, you will need to upload higher resolution files. We strongly suggest that you do not upload files smaller than 3500px on the long edge, and where possible, upload the full resolution file. 

More information about the minimum resolution requirements for prints can be found here.
