Here's your viewport size.
I'd appreciate it if you could add the portrait & landscape width (the first number) along with your device details to this form. First, please check to see if it's not already in the following list, as this spreadsheet contains all of the vetted submissions so far.
Note: I've made the viewport height less prominent since some users were incorrectly adding this as the landscape value. I also had to separate the form submissions due to people sabotaging the spreadsheet.
