Understanding 18x18 Pillow Cover Sizes

The term "18x18" refers to the dimensions of the pillow insert the cover is designed to fit – 18 inches by 18 inches. However, it's crucial to understand that the actual dimensions of the pillow cover might be slightly smaller.

Common Size Variations:

• True to Size: Some 18 x 18 pillow covers are precisely 18x18 inches.
• Slightly Smaller: It's more common to find covers that are 17.5x17.5 or even 17x17 inches.
• Envelope Style: Envelope-style closures might add a bit of extra fabric on one side.

Tips for Measuring:

• Measure Your Inserts: Always measure your pillow inserts before buying covers.
• Check Product Descriptions: Pay close attention to the product description for specific dimensions.
• Consider Fill Power: A higher fill power might require a slightly larger cover.
