Since the earth is not completely spherical, the diameter varies slightly from around the pole to around the equator.
. The rotation of the Earth causes the equator to bulge out slightly so that the equatorial diameter is 43 km larger than the pole to pole diameter.
In miles:(approximately)
Equatorial Diameter: 7937 miles
Polar Diameter: 7900 miles
or, in metric terms, (from another website)
Equatorial diameter 12,756.28 km
Polar diameter 12,713.56 km
Mean diameter 12,742.02 km

It's easy to work out - just find out the radius, and times by 2.

7,926 miles at the equator.
7,901 miles at the poles.
