Standard pillows are a common bedding accessory, typically measuring 20 inches by 26 inches. They are designed to provide support and comfort for the head and neck during sleep. Standard pillows can be filled with various materials, including memory foam, down, or synthetic fibers, catering to different sleep preferences. These pillows fit well in standard pillowcases and are often used on twin or full-size beds. They can also be paired with larger pillows, such as queen or king sizes, for added comfort. Standard pillows are widely available in stores and online, making them a popular choice for many households.
