Generally, I plan my rows or garden growing space to be no more than 4 foot wide, by however foot long I can fit into the space. Using even numbers really helps divide the space equally into perfect squares.
Sometimes I use graphing paper to draw out my garden beds with 4 tiny squares equaling one 12 inch x 12 inch square. It is also useful as a "map" to my garden. I notate variety names on my garden map to keep track. I try to mark varieties with plastic tags but sometimes they go missing. It is also a great reference for the next season, so I remember what was growing in that spot previously for proper crop rotation.
