Inside diameter. This doesn't take into consideration fittings which reduce diamater significantly.

All plastic tubing that I can think of is nominally sized by ID. If you look in the North American Maple Producer's Manual (or is it Handbook?) they have a chart for #taps at various slopes for each size tubing. If you don't have one of these manuals I highly reccommend you get one (the newest addition is either 2006 or 2007)
