Standard Sizes for Various Types of Furniture

Most furniture manufacturers produce items with standard furniture dimensions. Understanding some standard measurements before buying furniture makes planning and arranging pieces easier. Although these measurements are standard, always check the specific dimensions of an item you purchase to ensure it fits your needs.

Living Room Couch and Furniture Dimensions

Although one couch may look very different from another sofa because of style, color, or upholstery fabric, most sofas share similar measurements. Other living room pieces, such as coffee tables and end tables, are similarly sized. When you know roughly how big a piece is, you can plan how many pieces will fit and where they go so the room flows efficiently. Here are the standard table and couch dimensions, plus a few other items that you may want in your living space:

• Three-seat sofa: 38 inches deep by 90 inches wide
• Loveseat: 38 inches deep by 60 inches wide
• Armchair: 35 inches deep by 35 inches wide
• Coffee Table: 48 inches long by 30 inches wide
• Square end table: 24 inches long by 24 inches wide
• Rectangular end table: 28 inches long by 25 inches wide
• Four-shelf bookcase: 54 inches tall by 45 inches wide

Dining Room Furniture Measurements

Dining room tables and chairs are also usually made according to standard measurements. These have many variations for different kinds of dining tables. Chairs will vary slightly in size as well. The measurements below are what you can expect to find on average:

• Dining table with one leaf: 72 inches long by 36 inches wide
• Round dining table for four people: From a 36-inch diameter to a 44-inch diameter
• Rectangular dining table: 48 inches long (four people); 60 inches (six people); 78 inches (eight people); each 36 inches wide
• Side chair: 18 inches deep by 18 inches wide
• Armchair: 18 inches deep by 22 inches wide

Bedroom Furniture Measurements

Bedroom furniture usually includes a bed, one nightstand (or two), and a chest of drawers. Bed measurements are more standardized than any other furniture piece because beds need a standard-size mattress and bedding.

Nightstands and chests can vary, and there are several types of chests. The numbers below are for a basic, small chest:

• Twin-size bed: 39 inches wide by 80 inches long
• Double or full-size bed: 54 inches wide by 80 inches long
• Queen-size bed: 60 inches wide by 80 inches long
• Eastern king-size bed: 76 inches wide by 80 inches long
• California king-size bed: 72 inches wide by 84 inches long
• Chest of drawers: 30 inches wide by 18 inches deep
• Nightstand: 18 inches wide by 18 inches deep

Home Office Furniture

Home offices are often tucked into various places in the home, so their sizes and layouts greatly vary, sometimes making it a challenge to find furniture that fits the space. Home office desks were traditionally larger, but you can pick from smaller desks and chairs today. The dimensions will vary from manufacturer to manufacturer because there is an emphasis on office furniture that fits the user's body size and needs:

• Traditional office desk: 48 inches wide by 30 inches deep by 30 inches tall 
• Desk chairs: 20 to 22 inches wide by 36 inches tall
• Computer chairs: 18 inches wide by 36 inches tall

Patio Furniture

Patio furniture comes in all shapes and sizes. However, as outdoor rooms have evolved and become more sophisticated, so have patio furniture sizes, shapes, and styles. Choosing patio furniture, such as seating and dining sets, is similar to selecting living and dining room furniture.

• Rectangle dining table: 40 to 102 inches long by 42 inches wide by 28 to 30 inches average height of any size and shape table
• Square dining table: 30 to 64 inches square
• Round dining table: 24 to 60 inches in diameter
• Counter height table: 34 to 36 inches tall, any size and shape table
• Counter height chair/stool: 24 to 26 inches tall floor to top of seat
• Bar height table: 40 to 42 inches tall, any size and shape table
• Bar height stool: 28 to 30 inches tall floor to top of seat
• Chaise lounge chair: 78 inches long by 20.5 inches wide
• Coffee and end table: 15 to 19 inches tall, any size and shape of table
• Firepit table: 20 to 25 inches tall, any size and shape of table
  

Kitchen Furniture and Appliances

Kitchens consist mostly of cabinetry, ranges, refrigerators, dishwashers, and table sets if there's room. Standard cabinetry is sized to accommodate appliances to streamline the space. Kitchen islands, however, come in various sizes depending on their built-in amenities, and many are customized. Here are some sizes of basic kitchen furniture and appliances.

• Square breakfast table for four people: 36 inches by 36 inches
• Dishwasher: 24 inches wide by 24 inches deep by 35 inches tall 
• Side-by-side refrigerator (standard, not counter-depth): 30 to 36 inches wide by 29 to 35 inches deep by 67 to 70 inches tall
• Freestanding range: 30 inches wide by 36 inches tall
• Base cabinet: 36 inches wide by 24 to 26 inches deep by 35 to 36 inches tall
  

Custom Furniture

If the standard-size furniture you want won't fit into your space, consider ordering custom furniture and non-standard sizes. You can go the DIY route and make your furniture. Or try retailers, such as Ikea, where you may find just the right non-standard-size item that may fit a smaller—or much larger—space.

If you are shopping for furniture from another country, always check the dimensions because international measurements for furniture differ from standard sizes in the U.S.
