To ensure a good fit, a flat sheet should generally be larger than the mattress by at least 6 to 12 inches in width and length. This extra fabric allows the sheet to be tucked in securely under the mattress, providing a neat appearance and preventing it from coming loose during use. The exact dimensions can vary based on personal preference and the thickness of the mattress.
