There are some common questions that people ask about thread count when they buy new sheets. The first question most asked is how can it affect the quality of the sheets they buy? The answer to that question is complicated but easy to understand: it depends on the type of fabric they buy, what they buy it for, and how they wash it. Thread count in the sheets that a person buys does not directly correlate to the quality of the sheets they will get; however, there are a few things that can affect the thread count and quality of the sheets that one chooses to buy.
First, note that if one is purchasing a king size bed sheet or queen size bed sheet, then the thread count of the bed sheet will be slightly different. Generally, a 300-thread count sheet has 150 threads per inch, while a 300-inch bed sheet has 160 threads per inch. While this is certainly an important number to consider when purchasing a bed sheet, an excessively high thread count does not necessarily ensure excellent out-of-the-box comfort. It is generally best to purchase a bed sheet with a lower thread count if you plan on using it at night for sleeping or as a throw over, because the high thread counts of many synthetic materials do not provide good body support.
High thread counts of cotton and silk are commonly associated with luxury bedding materials, meaning those purchased at higher costs will generally provide better sleep and more comfortable temperatures. Cotton is a naturally breathable material that provides good heat regulation and comfort without being too warm or too cool in the summer and spring. Conversely, silk is a naturally cool material that provides good insulating properties for hot weather and cold climates. Thus, it is best to choose bed sheets with cotton or silk thread counts of at least 160.
