In 2006, the smallest Full Moon was on January 14, 2006. Its diameter was 29'40" because its distance to Earth was 402.927 km, near the apogee (the farthest point of an orbit to Earth). On the contrary, yesterday night Full Moon, on October 7, 2006, was the biggest of the year. Its diameter was 33'45" because its distance to Earth was only 354.027 km, near the perigee (the closest point of an orbit to Earth).
So, even if we think the apparent Moon diameter of the Moon doesn't change, in fact, its diameter increase by about 14%, 30% for its apparent surface.
