The average length of a sofa or a standard three-seater sofa measures around 70 to 90 inches, with the most common measurement being 84 inches. You can choose between an armchair or loveseat for a small room accommodating two people. Otherwise, longer sofas like four, five, or six-seaters work perfectly for bigger rooms accommodating more people.

Sofa Height

The sofa height is the measurement from the floor to the back. The sofa dimensions in inches range around 26 to 36 inches. If you are opting for a low-back sofa, the design is more precise and modern than a high-back sofa which is more traditional.

A seat depth of 21 to 22 inches might be suitable for average-height people. While shorter and taller individuals will find comfort in shorter and longer depths, respectively.

How to Measure Your Space for a Sofa

Online shopping can undoubtedly be an uphill battle, especially for first-time buyers. But, once you know how to measure the room space, it becomes easier to place the sofa. 

Step 1: Measure Your Space

The first step of sofa buying is understanding how much space you have. A large sofa with a traditional high back might appear perfect if you own a big room with high ceilings. On other hand, a small room with lower ceilings might compliment a loveseat or a one or two-seater sofa. Another critical thing to consider is measuring the height of doorways and hallways to ensure smooth delivery of the sofa. 

Step 2: Tape the Area

Select the spot where you wish to place your sofa. There need to be around 30 inches of moving space before the sofa. If you wish to place a coffee table, then there needs to be a minimum of 12 to 18 inches of space between the two pieces of furniture. 

Now, grab a masking tape and create a rectangle on the space where you would like to place your sofa – just a rough guideline. 

Step 3: Measure the Taped Area

After completing the taping task, ensure that you are completely at peace with the position and space. If you are, then measure the taped area and start looking for sofa dimensions either resembling or smaller than that. 

Conclusion

Having a thorough understanding of the sofa dimensions will help you throughout the buying process. There is no point in buying a huge sofa for a small room, and at the same time, placing a loveseat in a vast roomy space will not complement the space either. Therefore, this article might be beneficial if you are planning to buy a sofa.
