The best density for a wool carpet depends on various factors, including the intended use of the carpet and personal preferences. Density refers to how closely the fibers are packed together in the carpet. It is typically measured in ounces per square yard (oz/yd²) or grams per square meter (g/m²).
For residential use, a density of around 30 to 40 ounces per square yard (or 1020 to 1360 grams per square meter) is considered good for a wool carpet. This provides a good balance between comfort and durability. Higher-density carpets tend to be more durable and can withstand heavy foot traffic, but they may be less soft underfoot.
If the carpet is intended for a high-traffic commercial space, you might want to consider a higher density, perhaps in the range of 40 to 60 ounces per square yard (or 1360 to 2040 grams per square meter) or more, depending on the level of traffic.
It’s worth noting that other factors like fiber quality, pile height, and construction also play a significant role in determining the overall quality and performance of a wool carpet. Additionally, consulting with a carpet professional or manufacturer for specific recommendations based on your needs and preferences is a good idea.
