Just use this 2 functions, and see the example.
This accept multi-dimensional hash and array. 

my %H = (
a => { aaa => 111 ,
       bbb => 222 ,
     } ,
b => { ccc => 333 ,
       ddd => 444 ,
     } ,
c => [a,b,c,d, {x=>555,y=>666} , [w,w,w] ] ,
);

my ($keys,$vals) = HASH_size(%H) ;
print "Size of keys: $keys\nSize of values: $vals\n" ;

#############
# HASH_SIZE #

sub HASH_size {
  my (%hash) = @_ ;
  
  my ($KEYS_size,$VALS_size) ;
  
  foreach my $Key ( keys %hash ) {
    if ( ref( $hash{$Key} ) =~ /HASH/i) {
      $KEYS_size += length($Key)  ;
      my ($k,$v) = &HASH_size( %{$hash{$Key}} ) ;
      $KEYS_size += $k ;
      $VALS_size += $v ;
    }
    elsif ( ref( $hash{$Key} ) =~ /ARRAY/i) {
      $KEYS_size += length($Key)  ;
      my ($k,$v) = &ARRAY_size( @{$hash{$Key}} ) ;
      $KEYS_size += $k ;
      $VALS_size += $v ;
    }
    else {
      $KEYS_size += length($Key)   ;
      $VALS_size += length($hash{$Key})  ;
    }
  }
  
  return($KEYS_size,$VALS_size) ;
}

sub ARRAY_size {
  my ( @array ) = @_ ;
  
  my ($KEYS_size,$VALS_size) ;
  
  for(0..$#array) {
    if (ref(@array[$_]) =~ /ARRAY/i) {
      my ($k,$v) = &ARRAY_size( @{@array[$_]} ) ;

  return( $KEYS_size,$VALS_size ) ;
