Distribute visual weight to make the room feel balanced especially for small spaces. If you have a heavy piece of furniture but don't have another one to balance the weight, you can use the interior design furniture arranging trick which is incorporating bold or dramatic design elements to balance out the visual weight and make up for the missing heavy piece.

Don't crowd the entry

Same as the first tip, keep the entry way as free-flowing as possible. Keep bulky pieces of furniture away and don't let items sit too close to the door or potentially be in the way of the traffic flow.

Don't always push against the walls

Putting furniture up against the walls will make a room feel surrounded and a little too airy in the middle. A good interior design furniture arranging tip to apply is to pull furniture pieces away from the wall and use pieces as visual dividers to break the space into smaller seating arrangements. For more centered spots, stools and tables are great pieces to use.

Think about movement through the space

When doing interior design furniture arrangement, keep the pieces in positions that make the movement in the space smooth and as obstacle-free as possible. Arranging pieces and creating too many "small" traffic aisles between walls and furniture is a common mistake. To fix this, you can squeeze furniture together to create wider main travel aisles in the rooms; this will help generate obvious and intentional traffic flow.
