Step 1
Measure the dimensions of your home. This includes the length and width of the room you want to place the sectional in and the width of any entrances you must pass through to get the sectional into your home. If there are windows in the room, measure the height from the floor to the base of the window. Write down the length, width and height measurements of your room.
Step 2
Measure each section of the sofa to get the length measurements. Add the length measurements together to determine the total length. If the sectional is connected, measure the length of the sectional from one end piece to the other end piece. If the sectional is already connected, determine the length by placing the tape measure on the "right arm" of the sofa. Bring the tape measure diagnonally across the front of the sofa to the "left arm."
Step 3
Write down the sectional's length measurement. Add two extra feet to the length measurement to ensure there is sufficient walking space around your sectional.
Step 4
Measure the width of the sectional. To do this, measure the distance from the back of the sofa to the front. This should be done on the widest area of the sectional. Write down the sofa's width measurements.
Step 5
Determine the height of the sectional. To do this, measure the distance from the base of the sofa to the top. Write down the height measurements.
Step 6
Compare the length, width and height measurements for the sectional to the measurements of your home. If the measurement of the sectional is less than the length and width measurements of your home, the sectional will fit nicely.
