ASCII is a 7-bit character encoding with 128 values, covering control characters, digits, Latin letters, punctuation and symbols.

What range is standard ASCII?

Standard ASCII runs from decimal 0 through 127. Printable ASCII characters are decimal 32 through 126.

Is extended ASCII part of ASCII?

No. Extended ASCII usually means an 8-bit code page such as CP437, Windows-1252 or ISO-8859-1. The characters from 128 through 255 depend on the selected code page.

Can ASCII characters be used for ASCII art?

Yes. Printable ASCII characters can be arranged as glyph ramps, textures, borders or plain text art. AsciiThis uses glyph sets to turn images, GIFs, video and 3D models into editable ASCII art.

FAQ

What is the ASCII code for space?

The ASCII space character is decimal 32, hexadecimal 0x20, octal 040 and binary 0100000. In HTML it can be written as  .

What is the ASCII code for Enter?

Enter usually maps to line feed, carriage return, or both depending on the system. Line feed is decimal 10 and carriage return is decimal 13.

What is the difference between ASCII and Unicode?

ASCII is a 128-character encoding. Unicode is a much larger character standard that includes ASCII as its first 128 code points and adds characters for many scripts, symbols and emoji.

How does this connect to AsciiThis?

AsciiThis turns images, GIFs, video, prompts and 3D models into editable ASCII art. This reference page helps you inspect the characters that can become glyph sets, text exports and art-friendly ramps.
