Typing “square” in Excel might seem like a small detail, but it’s crucial for presenting data accurately in various fields, from mathematics and science to engineering and finance. Whether you’re calculating areas, dealing with quadratic equations, or simply need to display units like square meters (m²), knowing how to insert the superscript “2” is essential. This comprehensive guide will walk you through multiple methods, ensuring you can effortlessly type square symbols in your Excel spreadsheets.
Understanding the Need for the Square Symbol
Why is the square symbol so important? It’s more than just aesthetics. In technical documents, using the correct notation ensures clarity and prevents misinterpretations. For example, writing “m2” could be confused with other notations, while “m²” clearly indicates square meters.
Excel, being a versatile tool for data analysis and presentation, provides several ways to achieve this. Let’s explore the most effective methods.
Method 1: Using the Character Map
The Character Map is a built-in Windows utility that allows you to find and insert special characters, including the superscript two (²).
Accessing the Character Map
To open the Character Map, press the Windows key, type “Character Map,” and press Enter. The utility window will appear, displaying a wide array of characters.
Finding and Inserting the Square Symbol
In the Character Map, ensure the font is set to a font that supports the superscript two symbol, such as Arial or Times New Roman. Scroll through the characters or use the “Search” function to find the “superscript two” or “²” symbol. Select the symbol, click “Select,” then click “Copy.”
Pasting the Symbol into Excel
Now, go to your Excel sheet, select the cell where you want to insert the square symbol, and paste (Ctrl+V) the copied character. The superscript two will appear next to your text.
Method 2: Using the ALT Code
ALT codes are keyboard shortcuts that allow you to insert special characters by holding down the ALT key and typing a specific number sequence on the numeric keypad.
Enabling Num Lock
Before using ALT codes, ensure that your Num Lock key is activated. The numeric keypad is essential for this method to work correctly.
Entering the ALT Code
In Excel, select the cell where you want to type the square symbol. Hold down the ALT key and type 0178 on the numeric keypad. Release the ALT key, and the square symbol (²) will appear in the cell.
This method is quick and efficient once you memorize the code.
Method 3: Using the CHAR Function
Excel’s CHAR function converts a number into its corresponding character based on the ASCII or Unicode character set. You can use this function to insert the square symbol.
Understanding the CHAR Function
The CHAR function takes a single argument: the character code. The character code for the square symbol is 178.
Implementing the CHAR Function
In an Excel cell, type the following formula: =CHAR(178). Press Enter, and the square symbol (²) will appear in the cell.
This method is particularly useful when you need to generate the square symbol dynamically based on a calculation or condition. You can combine it with other Excel functions for more complex operations.
Method 4: Using the Superscript Formatting Option
Excel’s formatting options provide a way to format existing characters as superscripts, effectively creating the square symbol.
Typing the Number “2”
First, type the number “2” in the cell where you want the square symbol. For example, if you want to write “m²,” type “m2”.
Accessing the Format Cells Dialog Box
Select the number “2” that you just typed. Right-click on the selected cell and choose “Format Cells” from the context menu. Alternatively, you can press Ctrl+1 to open the Format Cells dialog box.
Applying the Superscript Effect
In the Format Cells dialog box, go to the “Font” tab. Under the “Effects” section, check the “Superscript” box. Click “OK.”
The number “2” will now appear as a superscript, creating the square symbol (²). This method is highly flexible as it allows you to apply the superscript effect to any character or number.
Method 5: Using the Symbol Dialog Box
Excel has a built-in Symbol dialog box that allows you to insert various symbols, including the square symbol.
Accessing the Symbol Dialog Box
In Excel, go to the “Insert” tab on the ribbon. In the “Symbols” group, click on “Symbol.” The Symbol dialog box will appear.
Finding and Inserting the Square Symbol
In the Symbol dialog box, select the font that supports the superscript two symbol. In the “Subset” dropdown, you can choose “Superscripts and Subscripts” to narrow down the search. Find the square symbol (²) and select it. Click “Insert” and then “Close.”
The square symbol will now be inserted into the selected cell in your Excel sheet.
Method 6: Copying and Pasting from Other Sources
Sometimes, the simplest solution is the best. You can copy the square symbol from other sources, such as a web page, a Word document, or even another Excel cell where you have already created it.
Finding the Square Symbol
Search online for “square symbol” or “superscript two” and copy the symbol from the search results. Alternatively, you can find it in any document where it is already present.
Pasting into Excel
In Excel, select the cell where you want to insert the square symbol and paste (Ctrl+V) the copied character.
This method is quick and convenient when you only need to insert the symbol a few times.

How do I type the superscript “2” for square in Excel using the Character Map?
To type the superscript “2” for indicating square using the Character Map, first open the Character Map application on your computer. You can typically find it by searching in the Windows Start Menu or in the system’s Accessories folder. Locate the superscript “2” character, which is often found within the “Superscripts and Subscripts” subset of a font like Arial or Times New Roman.
Once you’ve found the character, select it and click “Select,” then “Copy.” Now, in your Excel cell, paste the copied character after the number or variable you want to square. This method provides a reliable way to insert the superscript “2” when other methods are not suitable or available.
What is the keyboard shortcut to format a number as superscript in Excel?
Excel does not have a dedicated keyboard shortcut specifically to create superscripts like the number “2” for square. However, you can use a combination of keys to open the Format Cells dialog box quickly. Pressing “Ctrl + 1” will open the Format Cells dialog box directly.
Within the Format Cells dialog box, navigate to the “Font” tab. In the “Effects” section, check the “Superscript” box. After selecting “OK,” any characters you type in the cell will be formatted as superscript. While not a direct shortcut for the “2”, this offers efficient formatting for any superscript required, including creating the square symbol.
How can I use the CHAR function to display the square symbol in Excel?
The CHAR function in Excel can be used to display certain characters based on their ASCII or Unicode value. Unfortunately, there is no universal CHAR code for the superscript “2” that represents “squared.” While some character sets might include a suitable character, relying on CHAR is generally not the best approach for creating a universally recognized “squared” symbol in Excel.
Instead of directly using CHAR for the superscript “2”, consider combining the CHAR function with other methods, such as the text formatting options or the UNICODE function (if you are certain of a Unicode value within your specific font that represents the symbol adequately). However, relying solely on CHAR for “squared” symbols can lead to inconsistencies across different systems or fonts.
How do I quickly square numbers in a column and display the result with the superscript “2” using a formula?
To quickly square numbers in a column and display the result with a superscript “2”, you can use a formula combining the power operator (^) and text formatting. First, in a new column, enter a formula like `=A1^2&” m”`. Select the cell containing this formula, click “Format Cells”, go to “Font” tab, and select “Superscript” box for the “2” after the m.
Press OK and Drag the formula down the column to apply it to all the numbers you want to square. Using the superscript formatting ensures the “2” appears properly. This allows you to display the result with the area unit with the numbers properly squared in an adjacent column, with the units in square meters.
Why does copying and pasting a square symbol from Word into Excel sometimes not work correctly?
Copying and pasting special characters, including the square symbol, from Word to Excel can sometimes lead to display issues due to differing character encodings and font handling between the two programs. Word often uses more complex formatting and character sets than Excel’s default settings. This mismatch can result in the square symbol appearing as a different character or not displaying at all.
To improve the success rate of copying and pasting, try pasting the content as “Unformatted Text” in Excel. This removes the original formatting from Word, allowing Excel to apply its own font and character settings, potentially rendering the square symbol correctly. If this doesn’t work, consider using the Character Map or ALT code method described earlier to insert the symbol directly within Excel.
What are the limitations of using ALT codes to type the square symbol in Excel?
Using ALT codes to type special characters like the square symbol in Excel can be limited by several factors. First, the specific ALT code required for the superscript “2” (or any similar symbol) depends heavily on the active character set and the font being used in Excel. Different systems or regional settings might interpret the same ALT code differently, resulting in the wrong character being displayed.
Secondly, remembering and accurately typing ALT codes can be cumbersome and prone to errors, particularly for less frequently used characters. Furthermore, the availability of certain ALT codes might be restricted by the keyboard layout or operating system in use. For these reasons, while ALT codes can be useful in some situations, they are not always the most reliable or efficient method for inserting the square symbol in Excel.
How do I ensure the square symbol appears correctly when sharing an Excel file with others?
Ensuring the square symbol appears correctly when sharing Excel files relies on using methods that are less dependent on local system settings and font availability. Using the Format Cells method to apply superscript formatting is generally more reliable than pasting from external sources, as it instructs Excel to render the “2” using its internal formatting engine. Additionally, avoid relying on specific fonts that might not be installed on the recipient’s computer.
Before sharing, consider saving the Excel file in a compatible format, such as “.xlsx,” which supports more advanced formatting features. You can also convert the data into a PDF file, which preserves the visual representation of the square symbol regardless of the recipient’s system. Communicating clearly about the fonts used and any specific formatting requirements can also help prevent display issues on the recipient’s end.
