Hexadecimal can be done with 4 bars, representing 4 bits, on the top right = one hexadecimal digit.

For four quadrants, we get 4 x 4 bits = 16 bits = 2 byte digit.

0-65,535 in one digit. A digit reduction by a factor of 4.

Just a byte could be represented by a half-height vertical line, with only left and right "quadrants". A lower case number!

And a 4 byte = 32 bit number could be represented with one digit, with vertical and horizontal main bars. I.e. 8 quadrants. One "digit", 0-4,294,967,295.
