Board width question

[infinite.machinery]

I have adjusted the lines on dimension layer 20 to the width of the board that I need, 29.3 mm. When I look at the Board Information in the Inspector it shows 31.0586 mm. In fact it is showing that value no matter what width I adjust the dimension layer lines to.

Why is this? Should I be concerned? Is my board width really 29.3 mm?

Resolved. I remembered that I had asked this same question some time ago. Board width in the Inspector shows the outer location of any object laid out on the board. There was a label poking out from the board outline, causing the displayed width to be wider than I expected.
