Although the height of a coffee table comes down to personal preference there are some industry standards based on functionality and style.
Standard coffee table height.
The standard coffee table height is between 16 and 18 however we recommend choosing a coffee table height that pairs well with your sofa.
Since most sofas have a seat height of about 17 to 19 inches standard coffee tables are about 16 to 18 inches tall.
Most premade coffee tables range in height from 16 to 18 inches above the ground but a height of up to 21 inches is not uncommon.
This allows you to easily grab any drinks or food off the tabletop.
