Understanding Sectional Dimensions
Because sectionals are so customizable, their dimensions can vary widely. To help you measure accurately, here are a few key terms and general size ranges to keep in mind.
1. Overall Length (or Depth)
This refers to the combined measurement of the sectional’s components, such as the loveseat and corner chair. Typically, a sectional’s overall depth ranges from 94" to 156" (about 8' to 13'). Check the product’s "Weights & Dimensions" section for specifics.
2. Overall Width
The total measurement along the back of the sofa, spanning all components, like a chaise and armless loveseat. Sectional widths generally fall between 90" and 168" and are categorized as:
- Small: Less than 89"
- Standard: 90"–109"
- Large: Over 109"
3. Interior Measurements
If you’re planning to pair your sectional with a coffee table, make sure to consider the interior measurements—the space inside the sectional created by its shape.
4. Seat Depth
Seat depth can make or break your comfort. Measure from the front to the back of the seat and determine your preference:
- Shallow: Less than 21"
- Standard: 21"–28"
- Deep: 28"–35"
- Extra Deep: 35"+
5. Curved Sectionals
For curved sectionals, the dimensions listed often describe the smallest rectangular area the sofa can fit within. Use these measurements when mapping out your space.
Pro Tip: Don't forget to check the "Weights & Dimensions" tab for exact numbers and use them to compare models when shopping.
How to Measure & Replace a Sectional
If you’re upgrading your current sectional, replacing it with one of a similar size can make the process easier. Here’s how to measure your existing sectional for reference:
- Measure Width and Depth:
Use a tape measure to note the overall width (across the back) and depth (side to side) of the sofa.
- Measure the Height:
From the floor to the top of the arms and from the floor to the top of the sofa’s back.
- For Curved Sectionals:
Create an imaginary rectangular boundary around the curved sectional using masking tape. Measure the width and depth of this "box" to guide your new purchase.
Pro Tip: Use these measurements as a baseline for your next sectional. If you’re unsure of sizing, always go slightly smaller to ensure it fits well within your space.
How to Measure for a New Sectional Sofa
If you’re choosing a sectional for a completely new space, here’s a step-by-step guide to make the process painless.
1. Measure Your Room
- Use a tape measure to record the length, width, and height of your living room or the area where you plan to place the sofa.
- Don’t forget to measure hallways, doorways, and staircases to ensure the sofa can be delivered without issue.
2. Tape Off the Area
- Choose a spot for your sectional and mark its approximate footprint on the floor with painter’s tape.
- This gives you a sense of how much space the sofa will occupy and allows you to adjust as needed.
3. Measure the Marked Area
- Use a tape measure to note the dimensions of the taped-off space.
- Consider nearby windows—your sectional’s back should not be taller than the window sill.
Pro Tip: Leave a bit of breathing room around the sectional for outlets, side tables, and walking paths.
