HO scale is 1:87.1 Hot Wheels are approximately 1/64th scale. That is equal
to S scale or the American Flyer scale, so the cars are larger than HO. If
you are not particularly concerned about the scale, you can use them. Just
don't use HO scale cars near the Hot Wheels.

Wait--not so fast: I've looked through quite a few of those little cars
(and trucks, construction equipment, etc.), How Wheels and Matchbox, and
I seem to remember that not only are they not all the same scale, but
some of them were pretty dang close to HO. Close enough to be no matter.
Some of them have the scale molded on the bottom or printed on the
package, though most don't.

I seem to remember reading that makers like Matchbox scaled their
models to suit the size of their packaging - so models of larger sized
prototypes would be built to a smaller scale.

I suspect that's the case, since one merchandising requirement is that
all the little hanging cards fit into their alloted space on the display
rack. I have one piece in particular, a very nicely-molded front-end
loader, which looks to me to be dead-on HO scale.

That is correct. So, Matchbox (or Hotwheels for that matter) models
will vary in scale. Many Matchbox models have their scale engraved on
the bottom. Others don't. So, while passenger automobiles might be
around 1:64 scale, other items will be different. Each vehicle has a
different scale. So, even a Mini Cooper will be larger scale than a
model of a Cadillac Limousine. I suspect that some heavier construction
equipment is actually scaled down much closer to H0 scale in order to
fit into the "standard" Matchbox box.
