Hexadecimal 0-255 Chart
Every byte value 0-255 laid out in a 16x16 visual grid — the classic hex-chart layout that mirrors how the values naturally group by row.
How to Read This Chart
Every value 0x00-0xFF is arranged in a 16-column grid — each row holds 16 consecutive values, so the row you're in tells you the leading hex digit, and the column tells you the trailing digit.
Where This Chart Actually Comes Up
Getting a Visual Feel for the Hex Range
Seeing the full byte range laid out spatially, rather than as a long list, helps build intuition for where a given value sits relative to the whole range.
0x80 sits exactly at the halfway row
Quickly Spotting a Value's Neighbors
Finding a value in the grid makes its neighboring values (one more, one less, one row up or down) immediately visible without scrolling a long list.
0x4F sits next to 0x50 in the grid
Printing a Compact Reference Sheet
The grid's compact 16x16 layout fits more values into less vertical space than a row-per-value table, useful for a printed quick-reference sheet.

Limitations
- Hex values only — see the Hexadecimal Table for decimal and binary alongside each value.
Frequently Asked Questions
Why a 16x16 grid specifically?
Hex is base 16, so arranging values in 16 columns means each row starts at a multiple of 0x10 (16 decimal) — row 2 starts at 0x10, row 3 at 0x20, and so on, which mirrors the structure of the number system itself.
How is this different from the Hexadecimal Table?
The Hexadecimal Table is a row-by-row list with decimal and binary columns; this chart is a compact visual grid showing hex values only, organized to highlight the 16-per-row pattern.
How do I find a specific value quickly?
The row number (reading top to bottom, 0-indexed) tells you the leading hex digit, and the column position tells you the trailing digit — row 5, column 3 is 0x53.
Does this include decimal or binary values?
No — this chart is hex-only, for a compact, scannable grid layout. See the Hexadecimal Table or Hex to Decimal Table for a version with other bases.
