How to Type the UK Pound Symbol on Any Device

One of the most common reasons people search for the symbol for the UK pound is to find out how to type it on a keyboard that may not have a dedicated key. Depending on your operating system and regional settings, the method varies significantly.

Typing on Windows

If you are using a Windows computer, the method depends on whether your keyboard is set to a UK or US layout.

  • UK Keyboard Layout: Simply press Shift + 3. The pound symbol is usually printed on the '3' key on UK keyboards.
  • US Keyboard Layout: This is more complex because the '3' key produces the hash (#) symbol. To get the pound sign, you must use an Alt code. Hold down the Alt key and type 0163 on the numeric keypad (the block of numbers on the right side of the keyboard). Note that this usually does not work with the number row above the letters.
  • US-International Layout: If you have this layout enabled, you can often use Right Alt + Shift + 4 or Right Alt + 5.

Typing on macOS

Apple makes it relatively easy to find currency symbols across different layouts.

  • UK Keyboard: Press Shift + 3.
  • US Keyboard: Press Option + 3. This is a quick and reliable shortcut for American users working with British currency.

Typing on Mobile Devices (iOS and Android)

On smartphones and tablets, the pound symbol is hidden within the symbols menu.

  1. Open the keyboard and tap the 123 or ?123 button to access numbers.
  2. Tap the symbols button (often labeled as #+= or =\<).
  3. Locate the £ sign.
  4. Pro Tip: On many iOS and Android keyboards, if you press and hold the dollar sign ($), a pop-up menu will appear showing other currency symbols, including £, €, and ¥.

Typing on Linux and Unix

For Linux users, the Compose Key is the most efficient method. If enabled:

  • Press Compose + L + - (Compose followed by 'L' and a hyphen).
  • Alternatively, use the Unicode entry: Ctrl + Shift + U, then type a3, and press Enter.

Formatting Rules for the Pound Symbol

In professional and financial contexts, the placement and spacing of the pound symbol are governed by specific style guides, including those from the University of Oxford and the UK Government.

Placement and Spacing

The symbol is always placed before the numerical value. Unlike some European currencies where the symbol may follow the amount (e.g., 50 €), the pound sterling always precedes it.

  • Correct: £500
  • Incorrect: 500£ or £ 500

There should be no space between the symbol and the first digit. This is a strict rule in British English. When dealing with millions or billions, the symbol remains at the front.

  • Example: £10.5 million (not 10.5 £million).

Use with Decimals

When an amount includes both pounds and pence, the pound symbol is used, and a decimal point (a full stop) separates the units. In the UK, the decimal point is typically placed on the baseline, though some older styles placed it in the middle (a "middot"), but that is now rare in digital typography.

  • Correct: £9.99
  • Incorrect: £9,99 (The comma is used in many European countries but not in the UK for decimals).

Large Numbers and Commas

For amounts over 999, commas are used as thousands separators in the UK.

  • Example: £1,250.75 or £10,000,000.

The Origin and History of the £ Sign

The symbol for the UK pound is not just a stylistic choice; it is a historical abbreviation that dates back over a thousand years.

The Roman Connection

The "L" in the pound symbol stands for Libra, the Latin word for a balance or scales. In the Roman Empire, the libra pondo was a unit of weight. When the Anglo-Saxons established their currency system, they adopted the Roman measurement. A "pound" of silver was literally a pound in weight of sterling silver.

The horizontal bar (or bars) across the L is a traditional typographic convention used in the Middle Ages to indicate an abbreviation. It signaled to the reader that the "L" was not a letter in a word but a shorthand for a specific unit—in this case, the libra.

The Evolution of the Glyph

Historically, the pound sign was often written with two horizontal bars (₤). This version is still seen occasionally and is technically encoded in Unicode as the "Lira Sign." However, the Bank of England has used the single-bar version (£) almost exclusively on its banknotes since 1975.

In early printing, particularly during the 17th and 18th centuries, a simple capital "L" (often in a blackletter or italic typeface) was used instead of the symbol we recognize today. The Royal Mint continued to use a plain "L" in some official capacities as late as 1939.

Why is it called "Sterling"?

The term "pound sterling" is used to distinguish the British currency from other types of pounds (like the Egyptian pound) and from the unit of weight. The origin of "sterling" is debated by historians. One leading theory suggests it comes from the Old English word steorling, meaning "coin with a star," referring to the small stars that appeared on early Norman silver pennies. Another theory links it to the "Easterlings," Hanseatic merchants who were known for the purity of their silver.

The Pound Sign vs. The Hash Sign (#)

One of the greatest sources of confusion in international communication is the term "pound sign."

  • In the UK: "Pound sign" refers exclusively to the currency symbol £. The symbol # is called the "hash" or "octothorpe."
  • In the USA: "Pound sign" typically refers to the symbol #. This originates from the use of # to denote weight (e.g., a 5# bag of flour). Consequently, the telephone key for # is called the "pound key" in the US.

When communicating across the Atlantic, it is often safer to use the term "Sterling sign" for £ and "Hash" or "Number sign" for # to avoid expensive or confusing errors.

Technical Specifications and Coding

For web developers, software engineers, and data analysts, representing the pound symbol correctly in code is vital to ensure cross-platform compatibility.

Unicode and HTML

The pound sign is part of the Latin-1 Supplement block in Unicode.

  • Unicode: U+00A3
  • HTML Entity (Named): &pound;
  • HTML Entity (Decimal): &#163;
  • HTML Entity (Hexadecimal): &#xa3;

Using the named entity &pound; is generally recommended for HTML as it is easy for human editors to read and ensures the symbol renders correctly even if the document's character encoding is not set to UTF-8.

CSS and JavaScript

In CSS, if you need to insert the symbol using the content property:
