How to measure a wheel ?

I have been sold a unicycle as a 20", and I’m considering buying a 26" for long
distance riding. But I’m trying to figure out if it would be very different, and
I’m not sure that my 20 is really a 20. If I measure the exterior of the tyre, I
find 23.4" (60 cm * 0.39), but the interior of the whell is 19.5" (50 cm *
0.39). So what ?

Thanks for helping.

On the side of your tire should be some numbers like 1.75 X 20 That will tell
you what size your tire is.

The one you have described is a 24".
