One of the most popular sham sizes, the “Euro” Sham, measures 26 x 26.” Also known as a European or Continental sham, this decorative pillow is part of the main bed-scape, or “top of bed.” As part of the decorative look, Euro shams can have man different types of closures, and are meant more for propping yourself up in bed. A Queen bed typically has Euro shams, but a King bed needs 3 Euro shams to proportionately fill the bed’s width.
