I'm trying to validate the form field using jquery, if the size is greater than the number of cpf it puts the cnpj mask in that same field 

 var tamanho = $('.cpfcnpj').length;
    if (tamanho == 11){
        $(".cpfcnpj").mask('000.000.000-00',{reverse: true});
        alert("teste");
        }
    else if(tamanho > 12){
        $(".cpfcnpj").mask('00.000.000/0000-00',{reverse: true});
        alert("dois");
    }

When you do $('.cpfcnpj').val() , it brings the whole text completely, including the dots and dashes. That is, it will count the wrong size.

This is the correct way to do this and also as documented in the plugin itself: jQuery-Mask-Plugin 

var SPMaskBehavior = function (val) {
  return val.replace(/\D/g, '').length < 12 ? '000.000.000-009' : '00.000.000/0000-00';
},
spOptions = {
  onKeyPress: function(val, e, field, options) {
      field.mask(SPMaskBehavior.apply({}, arguments), options);
    }
};

$('.akira').mask(SPMaskBehavior, spOptions);

If you want to get the value from within .cpfcnpj , you have to use .val() . When you do this - $('.cpfcnpj').length; , it returns the number of elements with the class .cpfcnpj . 

var tamanho = $('.cpfcnpj').val();
if (tamanho.length == 11) {
    $(".cpfcnpj").mask('000.000.000-00',{reverse: true});
    alert("teste");
}
else if (tamanho.length > 12) {
    $(".cpfcnpj").mask('00.000.000/0000-00',{reverse: true});
    alert("dois");
}

You can read more about .val() here at this link: jQuery API Documentation .val ()
