While they did not have size specs listed for the Magnum Twisters, they did for the Magnums and Magnum XLs:Average condom: 190 mm long, 52 mm wide at both the base and head
Magnums: 215 mm long, 54 mm wide at the base, and 60 mm wide at the head
Magnum XL: 215 mm long, 54 mm wide at the base, and 65 mm wide at the head
This has some interesting implications for condom choice based on your shape. I’m thicker at the base, so from that standpoint, the XLs offer me no advantage over the regular Magnums. They are both equally long, so no advantage either way there, either.
So, it’s probably good for informed condom shoppers to realize that, at least in the case of Magnums, XLs and Twisters, ‘more girth’ means more girth at the top, not at the base, and not really a whole lot more at the base than average condoms. (If my math is right, that two extra millimeters translates into eight percent more area to the circle.)
For me, Magnums, XLs or Magnum Twisters are more comfortable, and are marginally more comfortable at the base, but only marginally at most. The extra length over ‘average’ condoms is a good thing.
