The 7 Furniture Arranging Mistakes Interior Designers Always Notice

Updated 06/18/18

We try our best when it comes to decorating, but sometimes, no matter how much thought we give to a room, something still feels off. It's hard to put a finger on the problem that causes an awkward furniture layout when you're not a professional architect or interior designer, which is why a little help from professionals is never a bad idea.

To help shed the light on the most common furniture arranging mistakes you might be making in your own space, we asked a group of interior designers to share their layout pet peeves. Yes, it is likely that if an interior designer walks into your home, they'll notice little details about your furniture arrangement that you may not have ever considered: Is the rug too small? Are the furniture pieces too close to each other or too far apart? Is the scale right for the space? Get ready to upgrade your room with very little effort.

These are the furniture arranging mistakes interior designers always notice (and how to fix them).

Mistake 1: Too Much Furniture

One of the main mistakes Hanna Egan, director of interior design at D'Apostrophe Design, always notices, is too much furniture in a room: "Keep good circulation around a living room furniture layout," she says. "A space should never feel too cramped, and there's nothing worse than having to do the cha-cha as you try to get up from your sofa, shimmying between the coffee table! At D'Apostrophe, every piece of furniture we choose has a purpose—from a large sectional to a side table. To achieve an overall aesthetic that is pure and simple with plenty of space, maintain a comfortable distance (minimum 18" if possible) from the edge of a sofa or lounge chair seat from the edge of the coffee table."

Christine Stucker, co-founder of Stewart-Schafer, also points this out as being the number one mistake she always notices: "Adding way too many pieces of furniture in a room can make it feel overcrowded and negatively impact the flow of the space," she explains. "We're firm believers in 'less is more.' Start with one incredible piece and build around it. For example, if you have a large sofa, you do not need to have two chairs flanking it. Instead, try adding one chair and a small side table, which will create balance in the room and allow for an uninterrupted sense of flow."

Mistake 2: Awkward Height Clearance

Another common mistake designers always seem to notice is height clearance. "I can't stress enough the importance of proper dining chair arm or task chair arm height versus table or desk height, not to mention leg clearance," says Egan. I can just hear the screeching and scratching of the furniture. Keep as much clearance as possible from the chair arms to the underside of the table. If there's a narrow pencil drawer, perhaps you even go armless."

Highlyann Krasnow of The Design High also points out the importance of coffee table height: "Make sure to size your coffee table height to your couch. Many modern companies' coffee tables are very low, which can not only look off but create a dangerous situation where someone could run into the table. To fix this, we suggest using two modular side tables as coffee tables. This brings an interesting, modern vibe to the room without the common low height tables. The same goes for picking a nightstand.

Make sure to measure your bed with the box spring, mattress, and frame included to assure the nightstand isn't too low or too high."

Mistake 3: The Wrong Rug Size

Most designers agree that bigger is always better when it comes to rug size: "Using too small of a rug in a living room setting can actually make the space feel much smaller," explains Stucker. "We've seen a lot of small-sized patterned rugs being placed underneath the coffee table, which makes the room look small and awkward. Rugs are a great way to create an aha moment and ground the space. We love using large natural fiber rugs, which add an element of luxury and sophistication."

Krasnow agrees: "Scaling your rug is extremely important. Measure to make sure your rug doesn't end up looking like a bath mat."

Mistake 4: Matching Furniture Sets

Gone are the days of living room sets, but interior designers still notice matching sets in homes they visit: "One of our pet peeves is when everything in a room matches," says Stucker. "Furniture sets that include a matching sofa, loveseat, and chair ends up looking like a showroom and can be very underwhelming. By mixing textures, colors, and even genres, you can create a much more elevated space that looks thoughtfully curated and well designed."

Egan also advocates for a thoughtful mix of furniture and furnishings: "We love to design with pieces that can curate space and movement themselves, and then we accentuate with composing objects and art. For that reason, we are extra conscious that clashing furniture and furnishing arrangements can make a space feel much smaller than it is. If art and decorative objects are part of your design, thoughtful placement is everything."

Mistake 5: Inefficient Navigation

Above all else, it's imperative that your furniture arrangement is conducive to easy navigation, but Garth Oldershaw, director of interiors at BCV Architecture + Interiors, points out that this is easier said than done: "I always notice when furniture disrupts the project flow. When an inefficient or careless furniture plan is confusing for people to navigate. We always strive for a clear initial plan that addresses potential complications that arise with an unusual space. Whether the feel is relaxed or refined, we believe the furniture selection and arrangement should reflect it."

Mistake 6: Furniture Against the Wall

One of the main pet peeves of interior designers everywhere is furniture pushed up against the walls: "Don't be afraid to float your couch," suggests Krasnow. "It can be tempting to push all furniture up against the wall, but this can create dead space in the center of the room. Leaving a few inches between your wall and sofa creates a more inviting environment."

Mistake 7: Wrong Furniture Scale

Krasnow also points out that dimensions are always key. "Scale furniture to the size of the room and search for vendors and furniture pieces accordingly," she says. "For example, Urban Outfitters has great options for a smaller room. In regard to furniture selections, using a loveseat instead of a couch or café table instead of a traditional dining can assure a cohesive look without overwhelming the room with large pieces."
