Test Results: Double vs. Single Stitching

Are menus with double-stitching stronger than menus with single-stitching?

To find out, KNG conducted a test to determine how much force was needed to rip the seams apart on both types of menu covers.

How We Tested

  1. Samples of the same size were made using like materials and processes to make the testing as consistent as possible.
  2. Five samples of each type were pulled apart to measure the amount of force required to break the stitch line.
  3. A video of the test is available below.

Results Of Tests

Summary: Single-stitched menus, like the ones KNG manufactures, are stronger than double-stitched menus.

  • Single-stitched menus were stronger, requiring an average of 126 lbs of force to pull the pieces apart.
  • Double-stitched menus were weaker, only requiring an average of 95 lbs of force to pull the pieces apart.

Other Considerations

Thread Strength: KNG uses one of the strongest threads available. To ensure a fair test, the same strong thread was used on both samples. Some competitors use a less reliable thread and may feel that doubling it up may help their menus be stronger. Our tests reveals just the opposite is true.

Plastic Quality: KNG uses high-quality, commercial-grade plastic. Even so, about half of the test samples ripped the plastic rather than breaking the thread. It is important to consider that thread and plastic work together to provide a strong or weak cover.

Needle Damage: Each time the plastic is punctured by a needle, it is weakened. This encourages the plastic to crack and split. The KNG technique uses a single needle that creates less heat and penetration damage.


This testing confirms that KNG menu covers using the single-stitched method with strong thread and high-quality plastic are the best covers on the market.
