How do I tell what size chain I need for my Stihl 291 chainsaw with a 20 inch bar? Also, does anyone have any good websites to order them from?
Thanks

When replacing a chain, match the following three specs:
PITCH
GAUGE
DL ( number of drive links)
As Tar12 mentioned, you may find this information stamped on a known compatible bar.
ASIDE: There is a fourth feature of a chain that sometimes comes into play with smaller saws. If your bar has a narrow kerf (NK), you have the option to use either a standard kerf chain or NK chain. If your bar is standard kerf, you can NOT use a NK chain on that bar. NK chains are found in .325 and 3/8LP pitches.
