How big of a hole should I make for four 14-2 wires

Currently, 4 12-2 Romex wires are hanging below a floor joist. If I want to make these wires go through a floor joist (2 x 10), how big of a hole should I make? Should I make one big hole or two small holes?

Thank you,

I never run more than 3 cables per hole. In this case I'd drill 2 sets of holes
3/4"-1" each and pull 2 cables through each.
