The range this is computed against
The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop.

Put KK up against a loose-passive calling range — 670 combos, 50.5% of all hands — and the exact answer is 78.7% equity: 78.4% outright wins, 21.0% losses and 0.7% chops. Your own two cards remove 71 of those combos before the flop is even dealt — a blocker effect this number already accounts for, because every combo containing one of your exact cards is stripped out of the range first. You are ahead of 592 of the 599 combos you can still be facing (99%), which is what a 78.7% number actually looks like hand by hand.
Where does the range come from? The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop. Broken down hand by hand, KK does worst against AA (18.1%), KK (50.0%) and AKs (65.9%) and best against K8o (93.8%), K7o (93.3%) and K9o (92.3%). Across the whole range KK's equity swings from 18.1% at the bottom to 93.8% at the top — the single 78.7% headline is the combo-weighted average of all of it.
A loose-passive calling range is the most profitable opponent in poker and 78.7% is why: KK crushes the whole thing, so the entire plan is to build the pot while they are calling with hands they should be folding.

What hands are in a loose-passive calling range?
105 hand classes and 670 combos — 50.5% of the 1,326 possible starting hands. By combo count it is 12% pocket pairs (13 pairs, 78 combos), 38% suited hands (64 classes, 256 combos) and 50% offsuit hands (28 classes, 336 combos). That shape is why KK runs at 78.7% against it rather than against a random hand.
Does KK do better against a wider or a tighter range?
Wider, almost always. KK has 78.7% equity against a loose-passive calling range (50.5% of hands) but 59.9% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
