The Earth is 45,075.02 km around (in circumference) at the equator.
It is 12,756.274 km in diameter at the equator.

doesn't anyone on this ******* website know how to use google?
but since I do, here's the biggest most confusing answer I could find
The Earth's shape is very close to an oblate spheroid—a rounded shape with a bulge around the equator—although the precise shape (the geoid) varies from this by up to 100 metres (327 ft).[19] The average diameter of the reference spheroid is about 12,742 km (7,913 mi). More approximately the distance is 40,000 km/Ï because the metre was originally defined as 1/10,000,000 of the distance from the equator to the north pole through Paris, France.[2

12,756 km in diameter. But it depends on which way you measure it. It is less from pole to Pole that across the equator, by about 50 km I think.

Depends on what you mean by size - how big around, how wide?
Mean diameter - 12,745.594 km
Equatorial diameter - 12,756.274 km
Polar diameter - 12,731.504 km
Mean circumference - 40,041.47 km
Equatorial circumference - 40,075.02 km
Polar circumference - 40,007.86 km
