I asked question before, but I sill do not know what to do.

I need to make the "contact number" field wider so phone number can fit.

Thanks.

You can make your own custom css. In this link you can see how you can change your custom css: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

For this case, I changed the class .form-textbox to 200px.

And here is how it seems:

Now you can fit a lot of text in the field.

Please if this doesn't fit or explain what do you need, just let me know.

Do you think about phone number field or contact number field, since the contact number can fit the phone number?

If you thought about phone number field, then you can try with @lgvalencia answer.

We'll await your response.
