How to Choose the Right Throw Pillow Size

Now that you know the different throw pillow sizes, you might be wondering how to choose the right one for your space. Here are a few tips to help you make the best choice:
Consider Your Furniture
The size of your furniture plays a big role in determining the best throw pillow size. If you have a large sectional sofa or a king-sized bed, go for larger pillows like 20 x 20 or 24 x 24 inches. For smaller furniture like armchairs or love seats, 16 x 16 inches or 18 x 18 inches are usually perfect.
Layer Your Pillows
Layering pillows is a great way to create a stylish and comfortable look. Start with larger pillows at the back and add smaller ones in front for a sense of depth. Don’t be afraid to mix and match sizes to create an inviting, cozy atmosphere.
Think About Comfort
If you plan to use your throw pillows for lounging or sleeping, comfort is key. Larger pillows generally provide more cushion, while smaller ones are better suited for decorative purposes. Choose a size that suits your needs, whether it's a supportive backrest or a soft, decorative accent.
Choose Pillows that Complement Your Decor
Your throw pillows should complement your existing decor. If you have bold, patterned furniture, opt for solid-colored decorative throw pillows in 18 x 18 or 20 x 20 inches to balance things out. If your space is more neutral, feel free to play with larger sizes or more colorful patterns.
Practical Considerations for Throw Pillow Sizes

Beyond aesthetics, there are several practical factors to consider when selecting throw pillow sizes.
Pillow Inserts vs. Throw Pillow Cover Dimensions
Here's an insider tip that many don't realize: for a plump, professional-looking pillow, always choose an insert 2 inches larger than your cover:
- For an 18×18 cover: Use a 20×20 insert.
- For a 20×20 cover: Use a 22×22 insert.
- For a 12×20 lumbar cover: Use a 14×22 insert.
Considering Pillow Fill and Fabric
While size is crucial, remember that pillow fill and fabric also impact the overall look and feel. A down-filled pillow will appear plumper and more luxurious than a polyester-filled pillow of the same size. Similarly, a velvet pillow will have a different visual weight than a linen pillow. Choose fills and fabrics that complement your style and comfort preferences.
Finding the Right Throw Pillow Sizes
When it comes to throwing pillows, size truly matters. The right throw pillow sizes can transform a space from ordinary to extraordinary. Whether you're looking for a cozy cushion to relax on or a stylish accent to complete your living room, selecting the proper size is the first step toward creating a comfortable and inviting space.
