Not very big by todays standards but made more effective by their delivery method. Hiroshima was a gun type Uranium 235, 12-15 thousand tons (equivalent TNT) or 50-63 Terra Joules (TJ) and Nagasaki was an implosion type Plutonium 239, 20-22 thousand tons (equivalent TNT) or 84-92 TJ.

Both were air burst bombs, maximizing destruction whilst minimizing fallout.
