How to Calculate Coffee Table Size (Step-by-Step)
A coffee table should be approximately 60% of the sofa length to maintain visual balance and easy reach.
Sofa Length × 0.6
Example: 84" Sofa × 0.6 = 50.4" Table
The table should be roughly the same height or 1–2 inches lower than the sofa seat for comfort.
Sofa Seat Height × 0.9
Example: 18" Seat × 0.9 = 16.2" Height
Using 25% of room width keeps the table proportional to the space.
(Room Width × 12) × 0.25
Example: 12ft Room (144") × 0.25 = 36" Width
Leave at least 18 inches between the table and seating for comfortable walking and legroom.
Minimum 18 inches
