How To Measure Sofa Size

Measuring a sofa correctly is crucial whether you're buying a new one, moving furniture, or making slipcovers. The right measurements ensure your sofa fits perfectly in your intended space, complements your room's proportions, and passes through doorways during moving. This guide will provide you with detailed instructions on how to measure sofa size accurately.

Understanding Sofa Dimensions:

A sofa's dimensions include its length, depth, and sometimes diagonal depth. Each measurement serves a specific purpose in ensuring the sofa fits your space and needs.

Materials Needed:

  • Measuring tape
  • Notepad and pen (for recording measurements)
  • Helper (optional, but useful for large sofas)

Step-by-Step Measuring Process:

  • Measure the Length: This is the longest side of the sofa, from one armrest to the other. Measure along the backrest to get the most accurate length.
  • Measure the Depth: The depth is the distance from the front edge of the sofa to the back. Measure from the outer edge of the seat all the way to the backrest.
  • Measure the Height: Sofa height is measured from the floor to the highest point of the sofa, usually the top of the backrest.
  • Measure the Seat Height: For seating comfort, measure the seat height from the floor to the top of the seat cushion.
  • Measure the Diagonal Depth: For moving purposes, measure the diagonal depth. Tilt the sofa back and measure from the bottom back corner to the top front corner. This helps in determining if the sofa can fit through doorways and hallways.
  • Note Armrest Height and Width: If your sofa has prominent armrests, measure their height and width, as they can affect how the sofa fits in your space.

Additional Tips:

  • Consider Doorways and Hallways: Ensure the sofa dimensions allow it to pass through doorways, hallways, and any turns.
  • Room Layout and Size: Factor in the size and layout of the room where the sofa will be placed. There should be enough space around the sofa for movement and other furniture.
  • Record Your Measurements: Write down all the measurements and keep them handy when shopping or arranging your space.


Measuring a sofa accurately is key to making informed decisions when buying, moving, or covering your sofa. By following these steps, you can ensure your sofa fits perfectly in your desired space, providing comfort and aesthetic appeal. Remember, careful measurement is the foundation of a well-planned living space.
