       Gopher menu width tests
       
       Note: some  of the following statements  are subjective. But
       keep in mind that readability  studies suggest that a column
       width of between 45 and 75 is easiest to read.
       
       <- 40 --------------------------------->
       
       Some '80s  home computers  had 40-column
       screens, such  as the  Commodore VIC-20,
       Commodore  64,  and  BBC Micro.  It's  a
       little cramped but  still readable. This
       is  also  about  the standard  width  of
       a  newspaper column,  but  keep in  mind
       that newspapers sacrifice readability in
       favor of high  print density. That said,
       if you're  technically restricted  to 40
       characters for whatever reason, it's not
       bad.
       
       <- 45 -------------------------------------->
       
       This is  the lowest recommended  column width
       for  readability. It's  great for  reading on
       phones in portrait mode.
       
       <- 55 ------------------------------------------------>
       
       A column width of 55  characters is slightly narrow but
       still quite  comfortable to  read. It's  definitely not
       too  wide. In  fact it's  great for  viewing on  mobile
       devices, especially phones in portrait mode.
       
       <- 56 ------------------------------------------------->
       
       <- 57 -------------------------------------------------->
       
       <- 58 --------------------------------------------------->
       
       <- 59 ---------------------------------------------------->
       
       <- 60 ----------------------------------------------------->
       
       A column width of 60  characters is very comfortable to read
       and is close  to optimal (it's exactly in the  middle of the
       recommended  range).  It's not  bad  for  viewing on  mobile
       devices, but it's about the limit for reading on most phones
       in  portrait  mode (at  least  for  someone with  less  than
       perfect eyesight).
       
       <- 61 ------------------------------------------------------>
       
       <- 62 ------------------------------------------------------->
       
       <- 63 -------------------------------------------------------->
       
       <- 64 --------------------------------------------------------->
       
       This is not a bad width to read, and it's a very round number in
       binary  (1000000) and  octal  (100) and  still  fairly round  in
       hexadecimal (40), if you care about that sort of thing.
       
       <- 65 ---------------------------------------------------------->
       
       A  column  width  of  65   characters  is  comfortable  to  read.
       Unfortunately it's slightly  too wide for reading  on most phones
       in portrait mode.
       
       <- 66 ----------------------------------------------------------->
       
       <- 67 ------------------------------------------------------------>
       
       <- 68 ------------------------------------------------------------->
       
       The  ancient UMN  Gopher client  cuts off  display strings  that are
       longer than  68 characters long  (it replaces missing  characters at
       the end with "..").  I find this odd because it  misses the RFC 1436
       recommended width by one character.
       
       <- 69 -------------------------------------------------------------->
       
       RFC 1436 recommends  keeping a Gopher display string to  less than 70
       characters long, so 69 is the  widest recommended width (at least for
       menus).
       
                                 *  *  *
       
       Note:  The following  widths are  wider than  what RFC  1436
       recommends for display strings. They  may or may not display
       properly in your Gopher client.
       
       
       <- 70 --------------------------------------------------------------->
       
       Some people misread or misinterpret RFC 1436 as recommending a display
       string  of "at  most  70  characters", but  it  actually recommends  a
       display string "less  than 70 characters". 70 is not  less than 70, so
       70 is right out.
       
       <- 72 ----------------------------------------------------------------->
       
       This is a popular width for email.  It's within the recommended 45 to 75
       characters for  readability (though near  the high end). I  believe this
       width  was  adopted so  as  to  keep  emails  readable on  an  80-column
       terminal,  even with  multiple levels  of quoting.  For that  purpose it
       works well.
       
       <- 76 --------------------------------------------------------------------->
       
       I've  seen  some  Gopher holes  with  a  column  width  of 76,  such  as  in
       server-generated directory  listings and CGI  output (all or most  that I've
       seen run  Gophernicus which has a  configurable column width). Why?  What is
       special about 76 columns?
       
       <- 80 ------------------------------------------------------------------------->
       
       This is a popular  width because most terminals are 80  characters wide, but for
       prose it's actually wider  than optimal. One lesson here is  that you don't have
       to fill the full width of your terminal with text.
       
       <- 100 -------------------------------------------------------------------------------------------->
       
       Why not go for a nice round value? Because it's too wide! I see no reason to stuff 100 characters in
       a line just because it's "round". (Also, it's not round in hexadecimal. 100 hexadecimal would be 256
       which is ridiculously wide, though 40 hexadecimal, or 100 octal, columns is not bad.)
       
       <- 132 ---------------------------------------------------------------------------------------------------------------------------->
       
       This is a common but less popular width because some common terminals  can switch to 132 column mode, and many line printers (due to
       the popularity of the IBM 1403  line printer which set the standard) printed 132 characters per line.  For writing code it's fine as
       you can see the end of even long lines, but for prose it's much wider than optimal.
       
       <- 256 -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------->
       
       Ah, a round value in hexadecimal. This is much, much, much,  much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much,  much, much, much, much, much, much, much, much, much, much too
       wide.
