A king sham insert is typically designed to fit a pillow measuring about 20 inches by 36 inches. This size matches most king-size pillow shams you'll find at Walmart. If you're shopping for an insert, always check the sham's packaging or product description to confirm the exact dimensions. Having the right size insert helps your pillow sham look full and keeps it comfortable for everyday use.

The best insert for a king sham depends on your comfort preferences and how you plan to use it.

• Down or feather inserts offer a plush, luxurious feel.
• Polyester inserts are hypoallergenic and easy to care for.
• Foam inserts provide extra support and shape retention.

The main difference is the size.

• King shams are larger, usually about 20" x 36".
• Standard shams are smaller, typically around 20" x 26".

The 2 2 1 rule is a simple way to arrange pillows on a king bed for a balanced look.

1. Place 2 king pillows at the back.
2. Add 2 decorative shams in front.
3. Finish with 1 accent pillow in the center.

To help keep your king sham inserts fluffy, try these tips:

• Give them a gentle shake and fluff daily.
• Air them out occasionally to release moisture.
• Follow care instructions for washing and drying—some inserts can be machine washed and dried with dryer balls to restore loft.
