How to change the size of the fields?

There is a question with the form of jotform, because it appears aligned to me, but to another person, in a different computer it looks different in the size of the fields and it looks misaligned.

So, I do not know if it's because of the browser, or for the type of computer, so how do we know the right size for the fields to make it look the same in every type of computer?

Please add this custom CSS code to fix the issue: 

.form-textbox, .form-textarea, .form-radio-other-input, .form-checkbox-other-input, .form-captcha input, .form-spinner input { 

    max-width: 590px !important; 

}
