Choosing the right size for cotton sheets depends on your mattress dimensions. Standard sizes include Twin, Full, Queen, King, and California King. To ensure a good fit, measure your mattress's width, length, and thickness (depth). Look for sheets labeled with deep pockets if your mattress is thicker or has a topper. Most sheet sets include a fitted sheet, flat sheet, and pillowcases, so pick a set that matches your bed size. Properly sized sheets help keep your bed neat and comfortable.

Thread count refers to the number of threads woven per square inch of fabric. For cotton sheets, a thread count between 300 and 600 is often considered ideal for balancing softness and durability. Sheets with thread counts in this range tend to feel smooth and last longer with proper care. Extremely high thread counts may not always mean better quality, so also consider the type of cotton and weave when selecting sheets.

100% cotton sheets are prized for their breathability, softness, and natural feel. They tend to absorb moisture well, helping you stay comfortable through the night. Cotton sheets are also generally durable and become softer with each wash. Compared to blends, pure cotton sheets may offer better temperature regulation and a more luxurious texture, though blends can sometimes be more wrinkle-resistant or budget-friendly. Your choice depends on your comfort preferences and care routine.
