Measure carefully. These pillows are somewhat larger than what I'd anticipated, as I really had to stuff them to get them to fit my euro shams. It's my own fault for not measuring. Just saying if you have standard euro shams with your comforter set, or whatever, you might find these particular pillows a bit too large for your liking, although I still made them work. The quality is excellent, and they're soft and comfy for lounging against.
