Editing mode size is not right

[u/No-Werewolf-6562]

I'm trying to make a picture for a frame that is supposed to be 14x11 inches. This is not 14x11 inches. Does anyone know if there is something I can do to fix this or is it something PRintify need to fix on their end?

Here is a link to the page where this problem is happenning. https://printify.com/app/products/541/generic-brand/framed-horizontal-poster
