What Size Pillow Insert Should You Use for a 17x17 Pillow Cover?

Pillow covers are a great way to update your home décor. By simply swapping out covers, you can refresh your space and adapt to changing seasons, trends, or moods. However, selecting the right pillow insert size for your pillow cover is essential to achieving the desired aesthetic and ensuring comfort. Purchasing the incorrect size of an insert can lead to a flat, lifeless pillow or an overstuffed, uncomfortable one. If you’re wondering what size pillow insert to use for your 17x17 pillow cover, this guide will provide you with all the answers and practical tips to make the perfect choice.

Understanding the Role of Pillow Inserts

Pillow inserts are the internal filling or cushions that go inside a pillow cover, providing the volume and substance that help the pillow hold its shape. They serve both functional and decorative purposes. In home décor, inserts create the plush, full appearance you love in throw pillows. Functionally, they ensure the pillow provides necessary support, whether it’s lumbar support, relaxation, or comfort during sleep. Choosing the perfect pillow insert size for a pillow cover—especially a 17x17-inch cover—requires consideration of various factors, including aesthetics, comfort, and durability.

The Standard Recommendation for a 17x17 Pillow Cover

When working with a 17x17-inch pillow cover, the general rule of thumb is to use a pillow insert that is slightly larger than the cover itself. A common recommendation is to select a pillow insert that is 18x18 inches. The reason for choosing a larger insert is to ensure the pillow looks plump and well-filled rather than saggy or underwhelming. Using an insert that matches the exact dimensions of the cover (17x17 inches) may result in a flat, lifeless appearance because the fabric doesn't stretch taut around the insert.

Why Oversized Pillow Inserts Are Ideal

There are several reasons why pillow inserts should be slightly larger than their corresponding covers:

• Fuller Appearance: Using an 18x18-inch insert inside a 17x17-inch cover guarantees a well-stuffed, plush look. Oversized inserts fill out the corners effectively, providing a streamlined and professional appearance.
• Enhanced Comfort: Oversized inserts tend to hold more filling and are more supportive, which enhances overall comfort. They create a cozy feeling and provide better support for lounging, backrests, or naps.
• Improved Durability: An insert that adequately fills the cover helps prevent fabric sagging or wrinkling, which reduces wear and tear. As a result, your pillow cover is better protected and remains in good condition for longer.

Factors to Consider When Selecting Pillow Inserts

While the general rule is to opt for an 18x18-inch insert when using a 17x17 pillow cover, certain factors may influence your final choice. Here are some key considerations to keep in mind:

1. Insert Material

Pillow inserts are available in various materials, including down, feather, polyester fiberfill, and memory foam. The material you choose can affect how well the insert fills the pillow cover. For example:

• Down/Feather: Down and feather inserts are soft and moldable, making them ideal for creating a luxurious look. If you choose this type, make sure the size is slightly larger (e.g., 18x18 inches) to fill out the corners fully.
• Polyester Fiberfill: Polyester fiber-filled inserts tend to retain their shape and offer a firmer structure. Oversized inserts work well with polyester-filled cushions to avoid sagging.
• Memory Foam: Memory foam inserts are dense and contour to pressure. Ensure you use inserts slightly larger than the cover dimensions to maintain a snug fit.

2. Pillow Style

The aesthetic style of the pillow can influence your choice of insert size. For a sleek, modern look, using a slightly oversized insert (18x18 inches) provides a tightly stuffed, tailored aesthetic. Meanwhile, for a more relaxed or bohemian style, using an exact-fit insert (17x17 inches) may complement a laid-back look if you want the pillow to appear softer and less structured.

3. Intended Use

The purpose of the pillow also plays a role in determining the appropriate insert size. For decorative throw pillows that are primarily used for visual appeal, you should prioritize plumpness and opt for larger inserts. However, for utility pillows where comfort is paramount (e.g., lumbar support pillows), you might prefer an exact-fit insert for a less rigid feel.

4. Fabric Type of the Cover

The fabric of your pillow cover affects how the insert interacts with it. For example, thicker fabrics like linen or velvet may naturally offer more structure, whereas softer fabrics like cotton or silk may require more filling to achieve a full appearance. Using a slightly larger insert helps to stretch and emphasize the beauty of softer fabrics.

Pro Tips for Choosing the Perfect Pillow Insert

To help you make the best decision, here are some practical tips when purchasing pillow inserts for 17x17 covers:

• Always Test Fit: If possible, test the insert with your pillow cover before purchasing. This ensures you achieve the exact look and feel you desire.
• Check the Corners: Make sure the insert fills out the corners of the cover completely. Corners that lack stuffing can create a sloppy appearance.
• Consider Compressibility: Some insert materials, like down and feathers, compress over time. Choose a slightly larger insert to account for future flattening.
• Don’t Overstuff: While larger inserts are ideal, there is a limit to how oversized you can go. Using an insert that is significantly larger than the cover (e.g., 19x19 inches or larger) can distort the cover’s shape and make it look overstuffed.
• Purchase High-Quality Inserts: Investing in high-quality inserts ensures they maintain their shape, fluffiness, and durability over time.

How to Measure Your Pillow Cover Correctly

Sometimes, errors occur because the measurements of your pillow cover were taken inaccurately. Here’s a quick guide to get precise dimensions for your 17x17 pillow cover:

• Lay the cover flat on a table and smooth out any wrinkles.
• Using a measuring tape, measure the width and height from seam to seam. Ensure the seams are taut but not overstretched.
• Repeat the measurement on both sides to confirm accuracy.

Keep in mind that pillow covers may shrink slightly after washing. It’s always a good idea to confirm the dimensions before purchasing inserts.

Final Thoughts

When choosing a pillow insert for a 17x17-inch pillow cover, opting for an 18x18-inch insert is usually the best choice. This slightly oversized insert guarantees a fuller appearance, greater comfort, and improved durability. However, other factors like insert material, pillow style, cover fabric, and intended use may influence your decision.
