Why use styles?
If you are writing a long document such as a dissertation or thesis, you will need to use styles to format the text. If you format it manually using the ribbons, or even short-cut keys, you will waste incredible amounts of time that you do not have. By using styles to format your headings and subheadings you will also be able to create an automatic table of contents which can be easily updated if you make any changes.
Paragraph styles can be applied to the different types of paragraph in your document (normal text, headings, subheadings, block quotations etc). Once you have applied the styles, a single modification (such as changing the size of a heading) will be automatically replicated throughout the entire document.
Styles can be accessed from the Styles Gallery on the Home ribbon:

By default, all text is initially formatted using the Normal style.
Step-by-step instructions
Displaying the full styles palette
If you are using styles in a long document, it is best to display the full style palette rather than relying on the Style gallery in the Home ribbon.
To display the palette:
- Click on the small dialog launcher in the bottom right of the Styles gallery.
This will display the floating style palette.
- Drag on the word Styles at the top of the palette and push it towards the left of the screen until it ‘docks’ at the edge of the Word window.
This will stop it obscuring any of your document.
- Click on the Show Preview box towards the bottom of the palette so that you can see what the styles look like.
Applying a style
- Place your insert point anywhere inside the text you wish to format (for example in a heading).
You do not need to select all of the text.
- In the style palette (or gallery) click on the style you wish to apply (for example Heading 1).
The paragraph will display the text formatting and spacing for the style you selected.
- Repeat this for all the paragraphs you want to be formatted using the same style.
Modifying a style
It is important for many other features to work that you use some of the default styles in MS Word such as Normal, Heading 1, Heading 2 etc. These often need modifying to meet your needs (blue fonts are not suitable for thesis headings for example). There are two different ways to modify styles as shown here:
Using the Modify Style dialog box
- Right click on the style name in either the Styles palette or Styles Gallery.
Alternatively you can left click on the drop-down arrow next to the name.
This opens the dialog box shown opposite.
- Change any common formatting using the options in the Formatting section (Font, Size, Emphasis, Colour, Alignment, Line Space, Space before, Indent).
- If you want to change anything that isn’t in the immediately visible options, use the Format button at the bottom left of the box to access all the other relevant dialog boxes.
Anything that you can change about text in a paragraph can be set using one of the dialog boxes accessible here.
- Once you have made your change, click OK.
Any text that had the style you modified applied to it will be automatically updated.
Updating to match selection
This is an alternative method which means you can see what your changes look like before you update the style.
- Place your insert point in a paragraph which has the style you want to modify applied to it.
If you are changing font options, you may prefer to select the text so that you can preview the changes you are going to make.
- Using the usual ribbon and dialog box options, make your changes to the text.
- Right click on the relevant style name in the Styles palette or gallery.
- Select Update [style name] to Match Selection.
Creating a new style
Sometimes you need to create a new style rather than edit an existing one. Remember though that new styles will not automatically be recognised by Table of Contents and some other automatic features.
- Click into a paragraph that is the most similar to the style you want to create.
New styles are based on the selected style so you can save work by making sure you are in the most similar one to begin with.
- On the Styles palette, click the New Style button from the very bottom
This opens a box almost identical to the Modify Style box.
- In the top section, give your style a name – it cannot be the same as an existing one.
- If necessary, choose which style you want to follow your new style (what style it returns to when you press the enter key).
- Edit the style options to your preferred new settings.
