It is an optical illusion. It is always the same size.
If you measure the moon with a ruler held at arm's length, you'll find it's always the same size no matter where it happens to be in the sky.
CHECK THIS SITE OUT. MOVE THE MAN AROUND AND YOU WILL SEE AN EXAMPLE OF AN OPTICAL ILLUSION.

It's actually an illusion, caused by the atmosphere. If you hold up a ruler and measure how large it looks from your point of view when rising and when in the sky, you'll see that both datum withh be the same.
