What would you suggest for seating arrangement?Updated a year ago
We recommend a minimum of 12" from the end of the table for end seating legroom. Then, for the sides of the table, the goal is to give each person around 24" for each seating area.
For the width of the table, the rule of thumb is that you want the footprint of the base (width at bottom) to be about 2/3rds of the top. However, If the table is taller than dining/desk height (30"), I suggest trying to go as wide as possible without forcing someone on the side to straddle a table leg.
So for "144", the length of the table base would be ~120" and the width (at bottom) would be a minimum 32"
