You're staring at a keyboard, trying to finish a math assignment or a DIY project list, and you realize you have no clue how to make that tiny "2" float in the air. It’s annoying. We’ve all been there. Whether you are calculating the area of a room for new laminate flooring or trying to explain $E = mc^2$ without looking like a total amateur, knowing the symbol for squared is one of those tiny digital literacy skills that saves a massive amount of time.
Basically, the symbol for squared is a superscript 2. It looks like this: $^2$.

In the world of mathematics, this is known as an exponent. It tells you to multiply a number by itself. Simple enough, right? But the "how-to" part gets messy because every device—Macs, PCs, iPhones, and Androids—treats this little character differently. Honestly, it’s kind of ridiculous that in 2026 we still have to hunt through menus just to find a basic math notation.
The History of the Little Floating Two
Before we get into the keyboard shortcuts, let's talk about why we even use this thing. Why not just write "x times x"?
Historians generally point to René Descartes. Back in 1637, in his work La Géométrie, he started using raised numerical exponents. Before Descartes, mathematicians were doing some truly wild and confusing things. Some used words, others used weird abbreviations, and some just wrote the variable multiple times like "xxx" for cubed. Imagine trying to do calculus with that mess. Descartes’ system stuck because it was clean. It saved ink. It made the page look less cluttered.
Today, the symbol for squared is a universal standard. If you see $5^2$, you know immediately the answer is 25. It’s the language of area, physics, and even some programming logic.

How to Type the Symbol for Squared on Any Device
This is where most people get stuck. There isn't a dedicated "squared" key on most English QWERTY keyboards. You have to be a bit of a "power user" (pun intended) to find it quickly.
Windows: The Alt Code Method
If you are on a PC with a number pad, you have the most powerful tool at your disposal: the Alt Code. You hold down the Alt key and type 0178 on the numpad. When you release Alt, the $^2$ magically appears. If you don't have a numpad, you’re stuck using the Character Map or a shortcut in Word. In Microsoft Word specifically, you can type your number, then press Ctrl + Shift + Plus Sign (+) to toggle superscript mode. Type your '2', and then hit that same shortcut again to go back to normal text.
macOS: The "Easy" Way
Mac users actually have it a bit easier if they know the hidden menu. You can press Control + Command + Space to bring up the Character Viewer. Type "squared" in the search bar, and there it is. Alternatively, if you’re in Pages or TextEdit, go to Format > Font > Baseline > Superscript. It’s a bit buried, but it works.
Mobile Devices: iPhone and Android
On an iPhone, it’s a bit of a pain. There is no native superscript button on the default keyboard. Most people just copy and paste it from a website. However, a pro tip is to set up a "Text Replacement" in your settings. You can make it so that whenever you type "sq2", it automatically changes to $^2$.
Android users often have it easier. On many Android keyboards (like Gboard), if you long-press the number 2, the option for the superscript $^2$ will pop up. It’s intuitive. It’s fast. Apple should really take notes here.
The "Caret" Workaround ($^$)
Sometimes, you can't use a superscript. Maybe you're coding, or you're using a plain-text editor that doesn't support fancy formatting. In these cases, we use the "caret" symbol: ^.
In Excel or Google Sheets, if you want to square the value in cell A1, you would type =A1^2. This is the universal "computer speak" for exponents. Most programming languages like Python or C++ also recognize this (though Python actually uses ** for exponents, which is a whole other rabbit hole).

Why This Little Symbol Matters for Your SEO and Formatting
If you’re a student or a professional writer, using the actual symbol for squared instead of writing "sq" or "^2" makes your work look infinitely more professional. It shows attention to detail.
From an accessibility standpoint, screen readers treat these symbols differently. A high-quality screen reader will read $x^2$ as "x squared." If you write it poorly, the AI might just say "x two," which can be confusing for someone trying to follow a complex formula.
Common Misconceptions About the Squared Symbol
One big mistake people make is confusing the symbol for squared with the symbol for "secondary" or "second." In some languages and older typewriter formats, a similar-looking mark was used for measurements of time or angles (like seconds of a degree).
Also, don't confuse $^2$ with the square root symbol ($\sqrt{x}$). They are functional opposites. While the squared symbol lives at the top right of a number, the square root symbol acts like a house sitting over it.
Real-World Applications You Probably Forgot
- Floor Area: When you buy a house, you’re looking at $ft^2$ or $m^2$. If the symbol is missing, it’s just a distance, not a space.
- Standard Deviation: In statistics, you square the differences to get rid of negative numbers. Without the $^2$ symbol, the math literally doesn't work.
- Typography: Graphic designers use superscripts to create "visual hierarchy." It keeps the number connected to its base without taking up extra horizontal space.
Actionable Next Steps
Stop hunting for the symbol every time you need it. Do these three things right now to save yourself future headaches:
- Set up a Text Replacement: On your phone, go to Settings > General > Keyboard > Text Replacement. Map "2sq" to $^2$.
- Memorize your Alt Code: If you're a Windows user, write "Alt + 0178" on a sticky note and put it on your monitor for a week.
- Check your Software: If you use Google Docs, go to Insert > Special Characters and search for "superscript" to see all the options available for different powers.
Using the correct symbol for squared isn't just about being a math nerd. It’s about clarity. In a world of digital noise, being precise with your characters ensures your message—whether it's a technical report or a simple text to a contractor—is understood perfectly the first time.
