Printable ASCII Table
A free printable ASCII table — all 128 codes with decimal, hex, optional octal/binary, and the character or control-code name. Exact-scale print.
This ASCII reference lists all 128 characters (codes 0–127). For each it shows the decimal and hexadecimal value — with optional octal and binary columns — and the printable glyph, or the standard abbreviation for the control characters (NUL, SOH, …, ESC, DEL). Codes are laid out across balanced columns in a monospace font so everything fits on one page.
It's a everyday desk reference for programmers, students and anyone working with text encoding, terminals or low-level data. Turn the binary and octal columns on or off, choose the number of columns and your accent colour, and print at exact scale.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
Does it cover the full ASCII range?
Yes — all 128 codes from 0 to 127, including the control characters (0–31 and 127) with their standard names.
Can I show binary and octal?
Yes — optional columns add the binary and octal value for each code alongside decimal and hex.
Are the control-code names included?
Yes — non-printable codes show their standard abbreviations such as NUL, TAB, LF, CR, ESC and DEL.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
