How to write your name in binary

  1. 01

    Find each letter

    Look up every letter of your name in the binary alphabet chart. Each one is a byte: 8 digits of 0 and 1.

  2. 02

    Mind the capitals

    A capital letter and its lowercase version are different bytes. Capitals start with 010 and lowercase letters with 011.

  3. 03

    Write the bytes in order

    Put the bytes side by side, one per letter. A space between first and last name is a byte too: 00100000.

Example: Emma in binary

Emma has four letters, so it takes four bytes. The capital E starts with 010; the lowercase m and a start with 011.
