The ring Antwerpen is bigger: R1, A11, R2 and A12 are part of that Ring.

Australia

Sydney Orbital Motorway - 110 km
M80 Metropolitan Ring Road (Melbourne) - 38 km (not a complete loop; it is not connected to the newly built Eastlink and there are no definite plans to build a connection, but it may live up to its name someday)
Perth ring road - 94 km (never heard it described as a ring road, but State Routes 2 and 3 do form a complete loop, even though route 3 isn't freeway standard all the way)

No other Australian city has anything resembling a ring road, unless you want to count the two-kilometre State Circle around Parliament House in Canberra.

What counts as a "beltways / ringroads / circular roads / orbital roads / circumferential roads or whatever they call"?

Only full circles? If not,here are some:

Győr(between main road 19 and 85):~23km(M1)
Nyíregyháza(between main road 4 and main road 4):~22,5km(M3 and main road 403) currently
Debrecen(between main road 4 and 35):~11km(M35 and nothern bypass) currently
Kecskemét(between main road 5 and 54):~17km(M5)
Szeged(between main road 55 and 5):~9,5km(M5 and M43) currently
Székesfehérvár(between main road 7 and local road in Szabadbattyán):13,5~km(M7)
Miskolc(between main road 304 and 3):~5,5km(M30) currently

Not necessarily full circles, but bypasses are not beltways. I'd say at least three quarters around a city or/and functions as a beltway.

The future MKAD was about 500 kms, right? The new Kiev beltway will also be 200+ AFAIK.

Could the "tangenziale" system around Milano (A51+A4/E64+A50/E35) be considered too?
I don't know its length.

I think it can be, though it's not a very aesthetic loop like the GRA.

It sure isn't aesthetic, but it's kinda "closed figure" and it should be more than 60km in length. On Italian Wikipedia I found these informations:

A50 - 31,5 km
A51 - 30,1 km

The "urban" part of the A4 should be something like 17 km (measured with Google Earth).

Forget measuring distances like that, Map24 does the job for you; the Milan(o) Ring measures 65 km.


Ljubljana Ring A1/A2/H3 (Slovenia) - almost 30 km

Indeed.

The Ken-O is still under construction. As far as I know, it is the longest beltway that is under construction. The Moscow / Kiev beltways are still plans as far as I know.

Johannesburg has a ring road, comprising of the N1, N3 and N12 (three freeways that converge on the city). Total length is 76km.

Cape Town doesn't have a ring road - there were plans to extend the R300 and make it a ring road, but these are on ice at the moment. Durban doesn't have one either - the N2 may be called the "Outer Ring Road", but it's more of a bypass than anything else.

Coastal cities usually don't have real ringroads, only bypasses.
