How to Make Pop Up Record Edit Full Width (not Skinny!)

How to Make Pop Up Record Edit Full Width (not Skinny!)

I have added a function to a record which pops the record open to edit in a new tab. This all works fine.

My function is really basic, it just uses the record ID and I took the link from the edit button:

  2. void quote.quoteManager_edit_popup(int inputID)
  3. {
  4. //This function just pops the quote in question open for editing. It is designed to work with the new Quote Page
  5. //
  6. linkURL = "https://creatorapp.zoho.eu/myCompany/appName/formName/record-edit/Quote_Manager_Report/";
  7. //
  8. completeURL = linkURL + inputID + "/";
  9. //
  10. openUrl(completeURL,"iframe");
  11. }

The only part I can't seem to work out, is how to make the pop up record/form FULL width, not skinny as per the below image.
