    This could be due to a configuration or theme you have applied to your form; however, the best way to change the field's width would be to inject some CSS code, here's an example:

    #fieldID {

        width: 150px !important;


    You will need to replace the "fieldID" with the real ID from your form and the width value with the needed value for your field.
