It’s also quality of the tape and how we used it. You could buy a tape and use it for 2, 4, or 6 hours with a tradeoff in quality. Blank tapes were rather expensive, so we all used 6 hours and then copied from there.
Commercially produced VHS tapes also tended to be higher quality than blank tapes, unless you went out of your way to buy the quality ones.
