Hi this is a better chart for those in metric....if your thread is 20, the that's most likely M20 which the guys in the US will call 138..... so the needle is a 140 which means its 1.4mm thick, or the old singer number or 22    Wizz's chart does not show the metric thread size.   When you get time print out the chart and laminate it.

I think both charts are helpful but I would have thought that the (Tkt) sizes in the second column as shown in the chart that @Wizcrafts is referring to could be taken as  being the metric sizes?? I only bother to point this out as the chart above does not have show all of the common needle sizes. For instance above it says for metric 40 to use a 110/18, but does not mention as in the other chart the 100/16 needles which I would more commonly use for that thread size. Same thing with the 19/120 needle size for the 30m thread etc. Often different leather/materials behave differently with one needle and being aware of close alternative sizes is important to know I think.

Sure RockyAussie, its not a competition, the guy is from Europe so would be more inclined to recognise M20 rather than ticket 20.....doesn't hurt to have a second chart.

The charts are only a guide, you cant expect them to be exact for every thread ever made.... anybody  can work out to try up and down to see what works best.   It also shows a 200 needle for M13 which might be better at 180... but when someone puts something up for nothing its hard to complain.
