Find the right size for coffee table does not need to be hard. The ideal height falls between 16 and 19 inches… That may seem easy.
It works well, because most sofas have a height of 17 to 19 inches from the floor to the upper cushion. The goal is to reach that same level or maybe lower by some inches. It forms a simple rule, when you know it.
Choose the Right Size Coffee Table
Here comes the two-thirds rule, and honestly, it probably is the most useful thing to remember. Your coffee table should have a length of about two thirds of the length of your sofa. When you have a broad sectional sofa, the needs for the table grow too.
The lengths can vary a lot, from 24 inches for small setups to 60 inches for bigger setups. About width, aim for between 18 and 24 inches as a good base. Most tables have a length bewteen 42 and 54 inches.
Do not forget the big picture. A table that is a bit too big tends to impress more than one that is too narrow… Like appearing too fancy dressed instead of simple to a party.
The distance from your seating matters more then many notice. You would want 40 to 50 centimeters of free space between the table and any chair or sofa. That ensures comfortable movement without a feeling of crowding in the space.
Most designers suggest aiming for around 12 to 18 inches from the edge of the sofa to the table. The table itself must sit so that each person can reach across it, around 18 inches works well from a seating position.
Living in an apartment requires other math. A typical coffee table for a small space measures around 40 inches and is at most 30 inches wide. If you truly lack place, do not go past 48 inches in length.
About height, staying at 14 to 16 inches allows the table to work without taking up the visible room. Square tables also deserve attention. Something of 30 by 30 inches commonly works well in small setups.
The layout of your living room and the shape affects the choice more than you think. Measure the room itself, take exact measurements of the height of your sofa and decide on a shape before you do anything. Here is a trick that I found useful: cut a bit of cardboard to the size of the table and lay it in your space.
You will right away see whether it works, without guessing.
The depth of the table depends partly on what else fills the room. Check the distance between your sofa and the TV or bookshelf to estimate what depth will truly work in your setup. Proportion is truly the main thing here.
Taller people sometimes need other proportions, and adjusting your furniture plan commonly shows theright solution. Round or oval tables may fit your room better than rectangles, so the shape deserves just as much thought as the measurements.
