Google Docs is a fantastic tool for writing and collaboration, but sometimes the formatting options can leave users scratching their heads. One common question is how to change the size of every period in a document. It might sound odd, but there are legitimate reasons for doing this. Like adjusting the spacing or ensuring consistency in a document's appearance. In this article, we'll walk through how to change all period sizes in Google Docs, step by step.
Why Change Period Sizes?
Before jumping into the technical details, let's consider why you might want to change the size of periods in your Google Docs. It might seem like a minor detail. Sometimes small changes can make a big difference. For instance, if you're a student trying to meet a page requirement, slightly larger periods can add a bit of length to your document. Or, you might be working on a design-heavy project where visual consistency is key, and uniform punctuation size contributes to that polished look.
Moreover, adjusting period sizes can help with readability. Larger periods might be easier on the eyes in a lengthy document. While these tweaks might seem minor, they can contribute significantly to the overall presentation of your work.
The Manual Method
Okay, let's get down to business. The most straightforward way to change all period sizes is manually. This method is time-consuming but straightforward if you have a short document.
Step-by-Step Instructions:
- Open your Google Doc.
- Press Ctrl + F (or Cmd + F on Mac) to open the Find tool.
- Type a period (.) into the search box.
- Click on the three vertical dots in the search box to expand the more options menu.
- Choose Find and replace.
- In the replace field, enter another period (.).
- Before clicking Replace all, click on the Format button at the bottom of the dialog box.
- Select Text, then Font size, and choose your desired font size.
- Finally, click Replace all to change all periods to the new size.
And there you have it! You've just changed all the period sizes in your document manually. This method works well for short documents or when you need to make other specific formatting changes.
Using Google Docs Add-ons
If the manual method sounds too tedious, especially for longer documents, consider using an add-on. Google Docs has a variety of add-ons that can help automate and enhance your document editing experience. One such add-on could assist with formatting, although finding one specifically for period resizing might require some digging.
Steps to Install and Use Add-ons:
- Open your Google Doc.
- Navigate to Add-ons > Get add-ons.
- Search for an add-on that deals with formatting or text style changes.
- Once you find a suitable add-on, click on it and select Install.
- Follow the on-screen instructions to complete the installation.
- After installation, access the add-on by going to Add-ons in the menu bar.
- Follow the add-on's instructions to adjust period sizes or general formatting as needed.
Remember, not all add-ons are created equal, and it might take some experimentation to find one that meets your needs. Always check user reviews and ratings to ensure you're choosing a reliable tool.
Utilizing Google Scripts
If you're looking for a more technical approach, Google Apps Script can be a powerful ally. With a bit of coding, you can automate the process of changing period sizes. This method is excellent for those who are comfortable with scripting and want a more precise solution.
Basic Script Setup:
- Open your Google Doc.
- Click on Extensions > Apps Script.
- In the script editor, delete any code in the window and paste the following:
function changePeriodSize() {
var body = DocumentApp.getActiveDocument().getBody(),
var searchPattern = '\\.',
var text = body.getText(),
var offset = 0,
while ((offset = text.indexOf('.', offset)) != -1) {
body.setFontSize(offset, offset + 1, 12), // Change '12' to your desired size
offset++,
}
}
- Replace 12 with your desired font size.
- Click the disk icon to save your script.
- Click the play button to run your script.
- You'll likely need to authorize the script to run, so follow any prompts to allow access.
This script loops through your document, finds each period, and changes its font size. While it may seem complex at first, it's a powerful way to ensure consistency across lengthy or detailed documents.

Pros and Cons of Each Method
Each method has its pros and cons, and the right choice depends on your specific needs and comfort level with technology.
Manual Method:
- Pros: Simple and straightforward for short documents.
- Cons: Time-consuming for longer documents, prone to human error.
Add-ons:

Ultimately, the method you choose should align with your document's requirements and your comfort with technology.

Alternatives to Changing Period Sizes
If changing period sizes doesn't quite solve your document's formatting issues, consider these alternatives:
Adjust Line Spacing
Line spacing can influence the readability and overall look of your document. Increasing the spacing between lines might achieve the effect you're looking for.
Modify Margins
Changing the margins can alter the document's layout and allow for more or less text on a page. This can be particularly useful for meeting specific page requirements.
Use Paragraph Styles
Applying paragraph styles to headings, subheadings, and body text can ensure a cohesive document design. This often has a more significant impact than altering punctuation.
These alternatives can be used in conjunction with period size changes to create a well-formatted document.


Common Mistakes to Avoid
When making formatting changes, here are some common pitfalls to watch out for:
Overformatting
It's easy to get carried away with formatting, but too many changes can make your document look cluttered. Stick to necessary adjustments and maintain a clean look.
Ignoring Readability
While aesthetics are important, readability should always come first. Ensure that any formatting changes don't negatively impact the ease of reading.
Not Saving Frequently
Always save your document after making significant changes. This prevents loss of work and keeps your progress secure.
By avoiding these common mistakes, you can ensure your document remains professional and effective.
