How can I configure the width of panes? I want to widen the preview.

[shmup]

I've tried various things with no luck, but it's the nth time I've realized I want to be able to control this, so here's an example image:

Simply, I'd like to reduce the width of the left pane, widening the right, preview pane.

You can use --preview-window argument.

    --preview-window=OPT   Preview window layout (default: right:50%)
                           [up|down|left|right][,SIZE[%]]
                           [,[no]wrap][,[no]cycle][,[no]follow][,[no]hidden]
                           [,border-BORDER_OPT]
                           [,+SCROLL[OFFSETS][/DENOM]][,~HEADER_LINES]
                           [,default][,<SIZE_THRESHOLD(ALTERNATIVE_LAYOUT)]

eg.

fzf --preview='bat {}' --preview-window=right,70%

For documentation sake, here's the script:

#  |)    (|

# ./fzfont and ^c to exit

if ! type figlet &> /dev/null; then echo "Requires figlet"; exit 1; fi
if ! type fzf &> /dev/null; then echo "Requires fzf"; exit 1; fi

FONT_DIR="$HOME/src/figlet-fonts"
cd "$FONT_DIR" || exit

while true; do
  clear
  printf "𝐞𝐧𝐭𝐞𝐫 𝐭𝐞𝐱𝐭 𝐚𝐧𝐝 𝐩𝐫𝐞𝐬𝐬 𝐫𝐞𝐭𝐮𝐫𝐧\n\n"
  read -r -p "> " input_text
  input_text=${input_text#> }

  font=$(find . -type f -name '*.flf' | sort -u |
    fzf --preview-window=right,70% --preview "figlet -f {} '$input_text'")

  if [[ -n $font ]]; then
    clear
    figlet -f "$font" "$input_text"
    printf "\nPress any key to continue...\n"
    read -rsn1 # disable \ escaping, silent input, read 1 char before returning
  fi
done
