Sofa Measuring 101: Understanding Sofa Dimensions and Sizes

When shopping for a new sofa, one of the first steps is determining the right size for your space. Measurements are key, but navigating all the sofa size terminology can be confusing, especially for those who are unfamiliar with furniture sizing conventions. To help, we’ve put together a guide to sofa measuring and size terminology.

Sofa lengths and widths

The most common sofa size is a three-seater, which is often referred to as a “standard size” or “standard length.” A standard length sofa measures between 74 and 96 inches in length, and ranges between 32 and 40 inches in width.

A two-seater sofa is typically between 58 and 72 inches in length, and between 32 and 40 inches in width. The most common width for a two-seater sofa is between 32 and 36 inches.

For those looking for a small sofa, a loveseat is the perfect choice. A loveseat usually measures between 48 and 68 inches in length, and between 32 and 40 inches in width.

Sofa heights

Sofa heights are measured from the ground to the seat cushion. The most common height for a sofa is between 17 and 19 inches. If you are looking for a lower sofa, a “couch” typically measures between 16 and 18 inches.

Sofa depths

Sofa depths refer to the sofa’s back-to-front measurement. Most sofas measure between 36 and 40 inches in depth, but some deeper sofas may measure up to 45 inches.

Sofa arm heights

Sofa arm heights are typically measured from the floor to the armrest. Arm heights vary by style, but the most common arm heights are between 27 and 30 inches.

Sofa seat cushion depths

Seat cushion depths refer to the distance from the back of the cushion to the front. The standard cushion depth is between 21 and 24 inches, but some deeper cushions can reach up to 28 inches.

Sofa cushion thickness

The most common sofa cushion thickness is between 6 and 9 inches. Thicker cushions may provide more comfort, but they can also take up more space, making them a better choice for larger sofas.

Sofa leg heights

Sofa leg heights are measured from the ground to the bottom of the sofa frame. Leg heights vary by style, but the most common range from 4 to 8 inches.

Now that you’ve learned the basics of sofa measuring and sizing, you can begin to shop for the perfect sofa for your space. With the help of this guide, you can be sure to find the right size and style that will fit perfectly in your home.
