What ever seems to work for you or whatever you prefer. I seldom actually measure at all, TBH, but when I do, I go ahead and calculate correctly. It isn't complicated. Still taking only two measurements, then a few keystrokes on the calculator or in Python or look up on the spreadsheet. Easy Sneezy. Most of the time, just eyeballing it is good enough.
