20 inch chainsaw chain: drive links, pitch and gauge

Questions people ask
How many drive links on a 20 inch chainsaw chain?
It depends on the pitch: 3/8": 70/72; .325": 78/80/81.
Are all 20 inch chains the same?
No. Pitch, gauge and drive link count all have to match your saw and bar. Two chains for the same bar length can differ in all three.
