How To Measure For Carpet Seams – Seaming Diagram

Carpet Seaming: Here are a few Tips for Measuring, Placement and a Sample Seaming Diagram. Figuring out how to measure for carpet seams and deciding on the best seam placement can be challenging. Below is a carpet seaming sample diagram and some important factors that need to be considered carefully. The goal is to place seams strategically to reduce wear and tear and also limit as much material waste as feasible.

Consider The Room Layout for Best Seam Location

  • In this example, the seam should be placed along the far wall, the opposite side of the entry door. This is the area with the least amount of foot traffic. The bed and nightstands will be placed along this wall.

Example of a 15 x 20 room with proper carpet seam placement. How To Measure For Carpet Seams

This Room Measures 15′ Wide by 20′ Long.

  • Since this bedroom is 15 feet wide… and because we are using 12-foot wide carpet, there must be a 3-foot  x  20-foot seam along one wall.
  • This room size is equal to 300 square feet (33.33 yards). However, due to the amount of necessary seaming, it will actually require using 324 sf. (36 yards.) of carpet.
  • The fill area needed is created by seaming together three pieces cut from a 12′ x 7′ piece of carpet.

Seaming Strategies

1. There would be way too much material waste if the fill area were created with just one solid piece, so to save money we will create the fill area using three pieces that need to be seamed together.

Based on the room width and length, three is the logical number of pieces to use to build this fill area. Using two pieces to build the fill area would cost a lot more money in materials and would create too much waste.

Using four pieces to build the fill area would take more time to prepare and not be cost effective. An hour of extra work to save a few dollars in materials is not realistic. Some installers charge extra for seam work beyond the norm. So the happy medium here is to create the fill piece using three pieces.

2. From a 12′ x 7′ piece of carpet, three pieces will each be cut to measure 4′ by 7′. That allows about 6 inches extra on all sides to allow for cutting, seaming and trimming. It is important to have enough material to work with, and factor in the need to cut, stretch and trim the carpet. Sometimes when preparing a seam the carpet edges may need to be re-cut make sure the seam looks as good as possible. With some carpet styles, using a serpentine edge is the best way to go to help hide the seam. Using the serpentine edge requires a little more material to align the seam.

3. With all seams, the nap of the carpet must always run the same direction. It’s like petting a cat, the fur lays down one way and stands up the other way. We use a 12′ x 7′ piece of carpet to build the fill areas to make sure the nap is going in the same direction.

In the sample diagram below, you can see how three carpet pieces are to be cut with a straight-edge and then seamed together to create one long 4′ x 21′ piece for the fill area. This will allow plenty of carpet to complete the installation after the main piece of carpet (12′ x 20′) and the created side fill (4′ x 21′) are seamed together.

Building the fill piece requires two 4-foot seams to connect the three 4′ x 7′ pieces together. This will create one single piece measuring 4′ x 21′ to fit the fill area, as shown with arrows. Then both sides of the 20-foot seam can be straight-edged and the final 20′ seam can be completed.

In this example, the total amount of carpet needed to complete this room is 12′ x 27′ (36 yards) or 324 square feet. A 12 x 20 for the main run and a 12 x 7 for the fill area.
