Writing mathematical expressions, scientific notations, or even just adding a touch of stylistic flair often requires the ability to use superscript characters. One of the most common superscripts is the squared symbol (²). While iPhones don’t have a dedicated “squared” key on the standard keyboard, there are several easy methods to achieve this. This article explores all the ways to type the squared symbol on your iPhone, ranging from the simplest shortcuts to more advanced techniques, ensuring you can always express yourself accurately and effectively.
Utilizing Text Replacement Shortcuts: The Speediest Method
Text replacement is a fantastic feature on iOS that allows you to define custom shortcuts for frequently used words, phrases, or symbols. This is arguably the quickest and most convenient method for typing the squared symbol on your iPhone.
Setting Up Your Text Replacement
The process of creating a text replacement is straightforward and only needs to be done once. After the setup, typing your chosen shortcut will automatically insert the squared symbol.
- Navigate to your iPhone’s Settings app.
- Scroll down and tap on “General.”
- Select “Keyboard.”
- Tap on “Text Replacement.”
- Tap the “+” button in the top right corner to add a new text replacement.
Defining Your Shortcut and Phrase
This is the crucial step where you define what you’ll type (the shortcut) and what it will be replaced with (the squared symbol).
- In the “Phrase” field, type or paste the squared symbol (²). You can copy this symbol from this article or another source. Alternatively, you can find the symbol using methods detailed later in this article.
- In the “Shortcut” field, enter a short, memorable sequence of characters that you’ll use to trigger the replacement. Good examples include “sqr,” “^^2,” or even “2^”. Choose something you won’t accidentally type in normal conversation.
- Tap “Save” in the top right corner.
Using Your New Shortcut
Now, whenever you type your chosen shortcut in any app (Messages, Notes, Mail, etc.), your iPhone will automatically replace it with the squared symbol. This makes writing “5²”, “area = length²”, or any other expression requiring the squared symbol incredibly fast.
Copying and Pasting: A Reliable Alternative
While text replacement is efficient, sometimes you need the squared symbol only occasionally. In these cases, copying and pasting is a perfectly acceptable alternative.
Finding the Squared Symbol
The first step is to locate the squared symbol. You can find it in various places:
- This Article: You can simply copy the symbol (²) from this article.
- Online Search: Search on Google or your preferred search engine for “squared symbol.” The symbol will appear in the search results or on various websites.
- Character Viewer (If Available): Some apps, particularly those on macOS, have a character viewer where you can find special symbols. Copying from such an application on your computer and pasting it into a note on your iPhone synced via iCloud is a viable, though slightly roundabout, method.
Copying the Symbol
Once you’ve found the symbol, simply select it and use the copy function:
- Tap and hold on the squared symbol (²).
- When the context menu appears, tap “Copy.”
Pasting the Symbol
Now you can paste the symbol wherever you need it:
- Tap and hold in the text field where you want to insert the symbol.
- When the context menu appears, tap “Paste.”
While this method is slightly slower than text replacement for frequent use, it’s a simple and reliable solution when you only need the squared symbol sporadically.
Using Third-Party Keyboard Apps: Expanding Your Options
The App Store offers a variety of third-party keyboard apps that provide extended character sets and functionalities, including easy access to superscript characters like the squared symbol.
Exploring Keyboard App Options
Several keyboard apps cater to different needs, from those specializing in emojis and GIFs to those offering enhanced character sets and typing features.
- Character Keyboards: Some apps specifically focus on providing a wide range of special characters, including superscripts and subscripts. Search the App Store for terms like “unicode keyboard,” “symbol keyboard,” or “special character keyboard.”
- Math Keyboards: If you frequently work with mathematical expressions, consider a keyboard app designed specifically for math. These apps often include dedicated keys for common mathematical symbols, including the squared symbol and other superscripts.
Installing and Configuring a Third-Party Keyboard
The process of installing and enabling a third-party keyboard is generally the same for all apps:
- Download the keyboard app from the App Store.
- Open the Settings app on your iPhone.
- Go to “General” > “Keyboard” > “Keyboards.”
- Tap “Add New Keyboard…”
- Select the keyboard you just installed from the list of third-party keyboards.
- Tap on the keyboard you just added, and enable “Allow Full Access” if the keyboard requires it for its full functionality (be aware of the security implications of granting full access).
Using the Third-Party Keyboard
Once the keyboard is installed and enabled, you can switch to it by tapping the globe icon in the lower-left corner of the standard iPhone keyboard. The specific method for accessing the squared symbol will vary depending on the keyboard app you’re using, but it will typically involve navigating through different symbol sets or using a dedicated character picker. Third-party keyboards provide a more integrated solution than copying and pasting, but they require installing an additional app and potentially granting it full access to your keyboard input.
Leveraging Unicode Character Codes (Advanced)
This method is more technical and less practical for everyday use, but it provides insight into how characters are represented digitally. The squared symbol has a specific Unicode character code.
Understanding Unicode
Unicode is a standard for encoding characters, assigning a unique numerical value (code point) to each character. The squared symbol (²) has the Unicode code point U+00B2.
Accessing Unicode Input (Limited Availability)
The standard iOS keyboard doesn’t directly support entering Unicode character codes. However, some apps (particularly those designed for coding or text editing) might provide a way to input characters using their Unicode code points. If you’re using such an app:
- Consult the app’s documentation to determine how to enter Unicode characters.
- Use the appropriate method to enter “U+00B2” (or its equivalent representation, depending on the app).
Limitations of the Unicode Method
This method is highly dependent on the specific app you’re using. Most standard iOS apps (like Messages, Notes, and Mail) do not directly support Unicode input. Therefore, this method is primarily useful for developers or users working with specialized text editors that offer Unicode support. While technically feasible, leveraging Unicode character codes is not a practical solution for most iPhone users who simply want to type the squared symbol.
Working with Different Apps: Specific Considerations
The way you type the squared symbol might vary slightly depending on the app you’re using.
Text Editors and Word Processors
Apps like Pages or Microsoft Word for iOS often have built-in formatting options that include superscript functionality. Instead of directly inserting the squared symbol, you might be able to type the number “2” and then format it as a superscript. This can be useful for creating more complex mathematical expressions or scientific documents.
- Pages: Select the number “2”, tap the “Format” button (paintbrush icon), go to “Text”, and then look for the “Baseline” option to adjust the text as Superscript or Subscript.
- Microsoft Word: Select the number “2”, tap the “Home” tab, tap the arrow to open the full menu, and then find the Superscript option in the “Font” section.
Social Media and Messaging Apps
Most social media and messaging apps treat the squared symbol as a regular character. Therefore, the text replacement or copy-and-paste methods are generally the most effective ways to type it in these apps. Some apps might automatically convert certain sequences of characters into the squared symbol (e.g., typing “x^2” might automatically display as “x²”), but this behavior is not consistent across all platforms.
Coding and Development Environments
As mentioned earlier, some coding and development environments might support direct Unicode input, allowing you to enter the squared symbol using its Unicode code point (U+00B2). Additionally, these environments often have specific syntax for representing exponents and mathematical operations. For example, in many programming languages, you would use the ** operator to raise a number to a power (e.g., x**2 to represent x squared).
Troubleshooting Common Issues
Sometimes, you might encounter problems when trying to type the squared symbol on your iPhone. Here are some common issues and their solutions:
Text Replacement Not Working
If your text replacement shortcut isn’t working, try the following:
- Double-check the spelling: Ensure that you’re typing the shortcut exactly as you defined it in the Settings app.
- Disable and re-enable Text Replacement: Go to “Settings” > “General” > “Keyboard” > “Text Replacement” and toggle the “Text Replacement” switch off and then back on.
- Restart your iPhone: Sometimes, a simple restart can resolve minor software glitches.
Squared Symbol Not Displaying Correctly
In rare cases, the squared symbol might not display correctly due to font compatibility issues. This is more likely to occur in older apps or on older versions of iOS.
- Update your apps: Make sure you’re using the latest versions of your apps.
- Update your iOS: Update your iPhone to the latest version of iOS.
- Try a different font: If possible, try using a different font within the app to see if it resolves the display issue.
Keyboard App Not Working
If a third-party keyboard app isn’t working correctly, try the following:
- Ensure Full Access is enabled (if required): Go to “Settings” > “General” > “Keyboard” > “Keyboards”, select the keyboard, and make sure “Allow Full Access” is enabled (if the app requires it).
- Remove and reinstall the keyboard app: Delete the app from your iPhone and then reinstall it from the App Store.
- Contact the app developer: If the problem persists, contact the app developer for assistance.
By understanding these various methods and troubleshooting tips, you can confidently type the squared symbol on your iPhone in any situation.
Question 1: Why can’t I find a dedicated “squared” key on my iPhone’s keyboard?
The standard iPhone keyboard is designed for general typing and prioritizes commonly used characters. The squared symbol (²) isn’t used frequently enough to warrant a dedicated key, as it primarily applies to mathematical and scientific contexts. Including specialized symbols like the squared symbol would clutter the keyboard, making it less efficient for everyday use.
Apple has prioritized simplicity and ease of use in its keyboard design. Users needing specialized symbols can access them through alternative methods such as the text replacement feature, copy-pasting from other sources, or using third-party keyboard apps. This approach keeps the default keyboard streamlined while still allowing access to a wider range of characters when needed.

The text replacement feature in iOS allows you to create custom shortcuts for frequently used phrases or symbols. To use it for the squared symbol, you navigate to Settings > General > Keyboard > Text Replacement and add a new entry. In the “Phrase” field, you would paste or type the squared symbol (²), and in the “Shortcut” field, you would enter a short, easy-to-remember sequence like “sqr.”
Once the shortcut is set up, every time you type “sqr” on your iPhone, it will automatically be replaced with the squared symbol (²). This provides a quick and convenient way to insert the symbol without having to search for it or copy-paste it from another source. The shortcut you choose should be unique to avoid unintended replacements while typing.
Question 3: Can I use a third-party keyboard app to get a dedicated squared symbol key?
Yes, there are several third-party keyboard apps available in the App Store that offer expanded character sets, including the squared symbol (²). These keyboards often cater to specific needs, such as mathematical typing or coding, and provide dedicated keys or easier access to less common symbols.
Installing and using a third-party keyboard is generally straightforward. After downloading the app, you need to enable it in Settings > General > Keyboard > Keyboards, adding it to the list of active keyboards. Then, you can switch between keyboards by tapping the globe icon on your keyboard during typing. Selecting the third-party keyboard allows you to access its unique features, including the squared symbol key.
Question 4: Is there an easy way to copy and paste the squared symbol from the internet?
Absolutely. One of the simplest methods is to search for “squared symbol” or “superscript 2” in any web browser on your iPhone, such as Safari or Chrome. The search results will almost certainly display the squared symbol (²) prominently.
You can then simply tap and hold the symbol on the webpage until the copy option appears. Select “Copy” and the symbol will be placed on your iPhone’s clipboard. You can then paste it into any text field where you need it, whether it’s in a message, email, note, or document.
Question 5: How can I find the squared symbol within the Character Viewer on my iPhone?
The Character Viewer, accessed through some apps that support rich text editing, allows you to browse and insert various characters. To find the squared symbol, you would typically tap and hold within a text field to bring up the contextual menu, and look for options like “Insert” or “Symbols” that lead to the Character Viewer.
Within the Character Viewer, you can scroll through different categories or use the search function to find the “Superscripts and Subscripts” category, where the squared symbol (²) is usually located. Selecting the symbol inserts it directly into your text field. The availability and exact steps might vary slightly depending on the app you are using.
Question 6: Does using the squared symbol in messages affect compatibility with other devices?
In most cases, using the squared symbol (²) in messages should not cause significant compatibility issues. Modern operating systems and messaging apps generally support Unicode, which includes the squared symbol. However, there’s a slight chance that older devices or systems with limited character set support might display the symbol incorrectly, possibly as a question mark or a box.
To minimize potential compatibility issues, consider the context and your audience. If you’re communicating with someone who you know uses an older device or system, you could alternatively spell out “squared” or use an alternative representation like “^2.” In most modern communication scenarios, however, the squared symbol should render correctly.
Question 7: Are there any apps specifically designed for scientific notation on the iPhone that include easier ways to input the squared symbol?
Yes, numerous apps cater to scientific notation and mathematical calculations on the iPhone. These apps often include features specifically designed for easy input of mathematical symbols like the squared symbol (²).
