In MS Word, you can adjust the spacing manually if the default spacing does not meet your needs.

Set Line Spacing and Paragraph Spacing in Word
Loose line or paragraph spacing can make text more readable, while tight line or paragraph spacing can fit more text in a document. Below are the steps to adjust the line spacing and paragraph spacing in a Word document.
- Create a Document instance.
- Add a section to the document using Document.AddSection() method, and then add a paragraph to the section.
- Set the before and after spacing for the paragraph using Paragraph.Format.BeforeSpacing and Paragraph.Format.AfterSpacing properties.
- Add another paragraph and set line spacing in the paragraph using Paragraph.Format.LineSpacing property.
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using Spire.Doc.Documents;
namespace SetSpacing
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Add a section
Section section = document.AddSection();
//Add a paragraph
Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("Spire.Doc for .NET is a professional Word .NET library specifically designed for developers to " +
"create, read, write, convert, compare and print Word documents on any .NET platform " +
"(Target .NET Framework, .NET Core, .NET Standard, .NET 5.0, .NET 6.0, Xamarin & Mono Android ) with fast and high quality performance.");
//Set spacing before the paragraph
paragraph.Format.BeforeSpacing = 30;
//Set spacing after the paragraph
paragraph.Format.AfterSpacing = 30;
//Add another paragraph
Paragraph paragraph2 = section.AddParagraph();
paragraph2.AppendText("Spire.Doc for .NET is a reliable API which enables to perform many Word document processing tasks. " +
