ASCII Table

The ASCII table lists all 128 ASCII codes, numbered 0 to 127, with their decimal, hexadecimal, octal and binary values, character names and HTML codes. Tap a printable character to copy it, and read the control codes' escape sequences beside it.

Printable characters (32 to 126)

Tap a character to copy it. HTML shows the named entity where one exists; the numeric form &#NN; always works.

Control characters (0 to 31 and 127)

These codes don't draw anything. They were designed to control teleprinters and terminals; a few, such as tab, line feed and carriage return, are still used in every text file.

Key facts

ASCII has 128 characters, numbered 0 to 127, which fit in 7 bits: 95 printable (codes 32 to 126) and 33 control codes (0 to 31 and 127).
ASCII was first published by the American Standards Association in 1963 as X3.4-1963, and revised in 1967 and 1986 (ANSI X3.4-1986).
Capital letters sit at codes 65 to 90 and small letters at 97 to 122, exactly 32 higher, so changing case flips a single bit.
Digits 0 to 9 are codes 48 to 57, so subtracting 48 gives the digit's value.
Code 3 is what Ctrl+C sends, shown as ^C in terminals, because Ctrl plus the letter 64 higher gives the control code.
The first 128 Unicode code points (U+0000 to U+007F) are exactly ASCII, so ASCII text is also valid UTF-8.

Which part of the table do I need?

Jump to the printable characters (codes 32 to 126) to copy a symbol or look up a letter, and to the control characters (0 to 31 and 127) for Ctrl combinations and line endings.

How do I read the ASCII table?

Each row is one code. Dec is the number in decimal, Hex in hexadecimal (base 16, as in 0x41 or \x41), Oct in octal (base 8, still used in some Unix tools) and Binary as the 7 bits ASCII uses. The HTML column shows the named entity where HTML has one, such as & for &, otherwise the numeric form A, which works for any character.

For control characters, Escape is the backslash sequence used in C, JavaScript, Python and many other languages, and Caret is how terminals show them: ^C is code 3, which is what Ctrl+C sends.

Which patterns in the table are worth knowing?

Range	What	Trick
48–57	Digits 0–9	Subtract 48 to get the digit’s value
65–90	Capital letters	Add 32 for the lowercase letter
97–122	Small letters	Subtract 32 for the capital
0–31, 127	Control codes	Ctrl plus the letter 64 higher, so Ctrl+G is 7, the bell

How does ASCII relate to ASCII art and other codes?

Every piece of ASCII art, with its galleries of pieces to copy, in the strict sense uses only the 95 printable characters in the first table, which is why it works in any terminal and any plain text file. Lines and boxes beyond -, | and + come from Unicode’s box drawing characters. Windows Alt codes are a different system, based on old code pages rather than ASCII alone; the alt codes page searches them by symbol and shows how to type them on a numpad or a Mac.

Sources: ASCII was first published by the American Standards Association in 1963 as X3.4-1963 and revised in 1967 and 1986 (ANSI X3.4-1986). Character names in the ASCII table come from the Unicode Character Database, which uses ASCII’s 128 characters for its first 128 code points.

Frequently asked questions

How many characters are in ASCII?

128, numbered 0 to 127, which fit in 7 bits. 95 are printable (the space, letters, digits and punctuation, codes 32 to 126) and 33 are control codes (0 to 31 and 127), which draw nothing and were made to control teleprinters and terminals.

What is extended ASCII?

Not one thing. "Extended ASCII" is a loose name for any 8-bit character set whose first 128 codes match ASCII, such as code page 437, Windows-1252 or ISO 8859-1. Codes 128 to 255 differ in each, so the same byte can show as é in one program and Θ in another. UTF-8 keeps ASCII's 128 codes as single bytes.

What is the difference between ASCII and Unicode?

ASCII has 128 characters for English. Unicode covers the writing systems of the world plus symbols and emoji, well over 100,000 characters. The first 128 Unicode code points (U+0000 to U+007F) are exactly ASCII, so ASCII text is also valid Unicode and valid UTF-8.

What is the ASCII code for a space?

A space is code 32, or 20 in hexadecimal, and it is the first printable character in the table. Codes 0 to 31 come before it and are control characters that draw nothing. The table shows the space as a symbol so that you can still tap it to copy.

What do the control characters do?

They were designed to control teleprinters and terminals, so they draw nothing. A few, such as tab, line feed and carriage return, are still in everyday use. Ctrl plus a letter sends them from a terminal: Ctrl+G is code 7, the bell, and Ctrl+C is code 3.

When was ASCII published?

The American Standards Association first published ASCII in 1963 as X3.4-1963. It was revised in 1967 and 1986, the latter as ANSI X3.4-1986. The character names in this table come from the Unicode Character Database, which uses ASCII's 128 characters for its first 128 code points.

How do I type an ASCII character that is not on my keyboard?

Tap it in the printable table to copy it, then paste. Windows Alt codes are a separate system, based on old code pages rather than ASCII alone, so use the alt codes page if you want to type a code on a numpad. Control characters are typed with Ctrl and a letter.

Is ASCII art made from this table?

Strict ASCII art uses only the 95 printable characters in the first table, which is why it works in any terminal and any plain text file. Lines and boxes beyond the hyphen, vertical bar and plus sign come from Unicode's box drawing characters. Our ASCII art galleries have pieces to copy.

How do I find the ASCII code for a character?

Find the character in the printable table and read the Dec column for its decimal code, or Hex for the base-16 value. The capital A is 65, which is 41 in hex and 1000001 in binary. For control characters such as Tab or Escape, use the control table, where the Escape and Caret columns show how they are written.

What is the HTML code for an ASCII character?

Where HTML has a named entity, the HTML column shows it, such as & for the ampersand. Every other character has the numeric form A, where 65 is the decimal code, and it works for any character. The numeric form is the one to rely on when you are unsure whether a name exists.

Why is A 65?

ASCII put the capital letters at 65 to 90 (binary 100 0001 to 101 1010) and the small letters at 97 to 122, exactly 32 higher. The difference is a single bit, so converting case meant flipping one bit, which was cheap for the hardware of the 1960s.

What are LF and CR?

Line Feed (10, \n) moves to the next line; Carriage Return (13, \r) moves back to the start of the line, both from typewriters and teleprinters. Unix and macOS end lines with LF, Windows with CR followed by LF, which is why text files sometimes show extra or missing line breaks when moved between systems.

What does ^C mean in the table?

It is caret notation, the way terminals display control characters. The caret stands for the Ctrl key and the letter is the key 64 codes higher, so ^C is code 3, which is what Ctrl+C sends. The Caret column lists the notation for every control code, including 127, which shows as ^?.
