According to the code below, the pin image and the MKPinAnnotationView are both 32 points wide and 39 points high:

- (MKAnnotationView *)mapView:(MKMapView *)mapView 
        viewForAnnotation:(id <MKAnnotation>)annotation
{
    MKPinAnnotationView *pav = (MKPinAnnotationView *)[mapView 
            dequeueReusableAnnotationViewWithIdentifier:@"test"];
    if (pav == nil)
    {
        pav = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation 
                reuseIdentifier:@"test"] autorelease];
    }

    pav.annotation = annotation;

    NSLog(@"pav.frame.size = %@, pav.image.size = %@", 
        NSStringFromCGSize(pav.frame.size), 
        NSStringFromCGSize(pav.image.size));

    return pav;
}
