A European, or euro, pillow is a square pillow measuring 26 by 26 inches. Although consumers can use these pillows for sleeping purposes, they are more often decorative pillows and are typically encased in shams and propped against the headboard of the bed.
Another name for the euro pillow is the continental pillow. The euro pillow is overall larger than the rectangular standard pillow, which measures 20 by 26 inches, and the queen pillow, which measures 20 by 30 inches. In making a king-sized bed using euro pillows, one should consider using three of these pillows encased in shams in front of the standard or king pillows. For queen or double beds, two euros suffice.
