Don't have any charts with measurements, but I'm a sewing machine tech, and work with all kinds of bobbins.
Just a reminder...only use the bobbins that were intended for your machine.
See, now, I knew some one here would know this info. And of course, the type of thread would make a difference, that's why I said, "Comparatively."

The reason I was thinking about this is that if one had 2 different machines to use for, say, FMQ, the type of bobbin, and therefore the amount of thread it holds, could be a deciding factor. So, I will try one of my 15 class bobbin machines instead of one that uses the 66 class bobbins. That way, I won't have to run out of bobbin thread as much. Its too bad that new Lydia uses 66's.
