Diameter does not affect gravity--only the mass of the body. A smaller earth with the same mass as today's earth would have the same gravity.
The centripetal force of a faster rotating planet would be different, though, and thus affect any weight we would feel.

Diameter does affect the gravitational force you feel at "sea level", because if the earth's diameter is smaller, then someone standing at "sea level" is closer to the center of the earth.

Since the acceleration gravity is inversely proportion to the radius squared, the diamet actually makes quite a lot of distance.

I didn’t see this reply before I post #77... sorry about that.
