You can select your desired print size prior to uploading your photos here: https://www.parabo.press/square-prints
If you choose the 4" size and change your mind, you can "Super Size Your Prints" before adding them to your cart to ensure you get the 5.5" squares!
App users that forget to upgrade- Just head to your cart, look for your square prints, and you'll see the Available add-ons option. Click that, and you'll be prompted to upgrade sizes.
Warning! Once you've selected 5.5" prints, you cannot revert back to 4" prints.
Unfortunately we are not able to change the size of your prints once the order has been placed.
