What size coffee table do I need?

The simplest rule for coffee table size is to match the table to your sofa. Aim for a coffee table that is half to two-thirds the length of the sofa, and two-thirds is the sweet spot: long enough to feel grounded, short enough to leave the sofa breathing room at each end. For an 84 inch sofa that points to a coffee table roughly 42 to 56 inches long. The calculator above works this out for your exact sofa, for rectangular, round, and square tables.

How tall should a coffee table be?

A coffee table should sit within 1 to 2 inches of the sofa seat height, so reaching for a drink feels natural rather than a stretch up or down. Most sofa seats land at 16 to 18 inches, which is why standard coffee tables are the same height. If your sofa seat is higher or lower than usual, enter the seat height above and the calculator matches the table height to it.

How much space between a sofa and coffee table?

Leave 14 to 18 inches between the front of the sofa and the coffee table. That is close enough to set down a cup or prop up your feet, with enough room left to walk past and stretch out your legs. Around the other sides of the table, leave about 30 inches where people walk, and at least 18 inches in tight rooms. Enter the open space in front of your sofa in the calculator to check the table and the walkway both fit.
