Excel 2016 oversizing once perfectly sized (in Excel 2013) userforms

[RawlinsCross]

Hi,

I have a spreadsheet written in Excel 2013 in Windows 7 at 1920x1080 with a userform that fits my screen perfectly (Height = 725, Width = 1161). Recently installed Excel 2016 in Windows 10 and ran the userform and it's quite a bit larger - so much so that information on the bottom of the userform visible in the old version is off screen and I can't pull the userform up to view.

Any thoughts on what the issue is here?
