organizar formulario

blz galera.

galera como faço para organizar um form sem ficar criando tabela e linha e colunas

fiz um form simples, nao consigo organizar para ficar alinhado usando o bootstrap

<form action="" method="POST" name="formulario" class="form-horizontal" id="formulario">
 <div class='form-group'>
 <label><span>Nome:</span>
 <input type="text" name="nome" required="required" class="input-xlarge" size="60" value="">
 </label>
 </div>
 <div class='form-group'>
 <label><span>Email: </span>
 <input type="text" name="email" class="" size="60" value="">
 </label>
 </div>
 <div class='form-group'>
 <label><span>Cpf/Cnpj: </span>
 <input type="text" name="cpfCnpj" required="required" class="" size="20" value="">
 </label>
 <label><span>Identidade: </span>
 <input type="text" name="rg" class="" size="20" value="">
 </label>
 <label><span>Insc Estadual: </span>
 <input type="text" name="ie" class="" size="20" value="">
 </label>
 </div>
