How large is the average supernova? - Quora
WebA good rule of thumb is that supernovae have a size of about D = 2 v t = 20, 000 km s − 1 × t = 0.02 pc ( t 1 yr) So a very young, 1-year-old supernova is about 0.02 pc across, an older supernova like 1987A is about 0.6 pc across (it's actually a bit less than that), and a supernova remnant like Cassiopeia A is about 6 pc across (a bit less).
