According to industry standards, how much should new tufted carpet with synthetic backing be stretched?

New tufted carpet with synthetic backing should be stretched by at least 1% in both length and width according to industry standards. This percentage is critical to ensure the carpet is properly installed without any looseness, which can lead to wrinkles and other issues over time. Stretching the carpet adequately creates a taut appearance and helps prevent premature wear.

The 1% guideline is a recognized standard that balances the need for a snug fit with the practical considerations of installation. When carpet is stretched correctly, it allows for the natural expansion and contraction that can occur in different environmental conditions, maintaining its integrity and aesthetic over time.

Other percentages specified in the choices are not aligned with standard practices for this type of carpet. A stretching percentage lower than 1% would likely not provide the secure attachment necessary, while higher percentages may be excessive and could lead to issues such as damage to the carpet or difficulty in installation.
