Balazs Lazer Speed Bag Sizing

[Z_0]

I recently purchased a Balazs Lazer speed bag, size large, 11 x 8, through Amazon. It looks like a nice bag but it is smaller than I expected.

I carfeully measured it and found:
Length from bottom of bag to top, including the loop = 11 inches
Length from bottom of bag to top, excluding the loop = 10 inches
Circumference at widest region = 23 inches
Diameter at widest region = 7.3 inches

This is about what I would expect for a 10 x 7 bag, not an 11 x 8 bag.

Does anyone else have experience with Balazs Lazer speed bag sizing?

Thanks for your help.

This has been a bit of an issue with not just Balaz but with not only the current makers but going way back to the early post WWII era. Of late the most believable theory has to do with the conversion from metric to English measurements, rounding off to the closest number.
