The calculation is aiming for a minimum width of 1200px, which seems to be the minimum size needed to display both sidebars. Since the original calculation uses `physicalDotsPerInch`, I'm only able to use my own laptop as a test subject. It's a 15" 1920x1080 screen. Checking `physicalDotsPerInch` gives me a value of ~1.47. That's how I derived the value of 815 to multiply by. The `qBound` function should keep the size to something reasonable, regardless of the screen size. I don't have another machine to test on (particularly not a HiDPI screen), so this is going to need a test or two. It's possible that `physicalDotsPerInch` may not be the ideal base for the calculation, in which case some more advanced algebra may be required.
