How do you know which prewound bobbin to buy? My manual doesn't say anything about my bobbin's size.

Most of the places that sell the bobbins know what letter your machine will take. I love pre wound you can get more pieces sew with the pre wound
Some people will say there machine doesn't work well with them . I used them in all my machine

I absolutely love prewound bobbins, they do go so much further. I haven't tried them in my longarm yet because of all the different shades of threads that I use. But for my Pfaff 2144 I love prewounds.
