You are completely normal if you’ve never thought about sofa seat cushion depth before. But it’s actually the unsung hero of furniture comfort. Seat depth doesn’t vary much—it’s typically between 21 and 24 inches (although some pieces go even deeper than that). Your ideal seat depth comes down to your height and how you’ll be using your piece of furniture. Seat Depth is one of the four factors we use in our comfort rating system, ABCS Comfort Metrics (the other three are Cushion Fill, Arm Height, and Back Support). On The Stated Home, we rate the depth of our furniture pieces as a 1 (21 to 22 inches deep), 2 (23 to 24 inches deep), or 3 (more than 24 inches deep).
First, a definition (because we love to know everyone is on the same page). Seat depth is the dimension from the edge of the front of the seat to the front of the back cushion.
Here are the questions to think about when deciding on ideal seat depth:
How tall are you and your family?
If you or your family members are on the petite side, you’ll probably want a shorter seat depth (shoot for 21 to 22 inches) so your feet will touch the ground. Taller individuals will find the majority of seat depths comfortable, but if you’re above 6’2”, you will probably prefer a deeper seat of at least 23 inches.
How do you sit on your sofa?
Not everyone always sits straight with both feet on the floor. If you love to pull your feet up on the sofa to tuck them under you or sit cross-legged, you’ll want at least 23 inches (and preferably 24 inches).
Are you a spooner?
If you want to cuddle with your honey or your dog (and who doesn’t!) without one of you almost falling off the sofa, a 24-inch depth (or even more) will let you do that.
What’s the size of your room?
Personal preferences aren’t the only factors—you also want to take a look at your room. If it’s a small parlor, keep your seat depth to 21 or 22 inches. If it’s a huge great room, something deeper will look more natural.
What sofa is right for you?
Now that you’ve decided what seat depth is best for your comfort and space, here are some sofa styles for each depth:

Comfortable for lounging with your feet up, but only the really tall would be able to sit upright with their feet on the ground.
