Page margins are the blank spaces between the body content and the page edges. In Microsoft Word, the default margins of each page are set as 1 inch, but sometimes you may need to resize the margins to accordance with your requirements. In this article, you will learn how to set page margins for Word documents in Java using Spire.Doc for Java.

Install Spire.Doc for Java

First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Set Page Margins in Word in Java

The following are the steps to set page margins in a Word document:

• Initialize an instance of Document class.
• Load a Word document using Document.loadFromFile() method.
• Get the desired section through Document.getSections().get(sectionIndex) method.
• Set the top, bottom, left and right margins for the pages in the section through Section.getPageSetup().getMargins().setTop(), Section. getPageSetup().getMargins().setBottom(), Section. getPageSetup().getMargins().setLeft(), Section.getPageSetup().getMargins().setRight() methods.
• Save the result document using Document.saveToFile() method.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;

public class SetPageMargins {
    public static void main(String []args){
        //Create a Document instance
        Document document = new Document();
        //Load a Word document
        document.loadFromFile("Sample.docx");

        //Get the first section
        Section section = document.getSections().get(0);

        //Set top, bottom, left and right page margins for the section
        section.getPageSetup().getMargins().setTop(17.9f);
        section.getPageSetup().getMargins().setBottom(17.9f);
        section.getPageSetup().getMargins().setLeft(17.9f);
        section.getPageSetup().getMargins().setRight(17.9f);

        //Save the result document
        document.saveToFile("SetMargins.docx", FileFormat.Docx_2013);
    }
}
