Throw pillows are a versatile and stylish home accessory that can add color, texture, and comfort to any space. Whether you’re decorating your couch, bed, or armchair, choosing the right size throw pillow is essential for achieving the desired aesthetic and functionality. In this guide, we’ll explore the various sizes of throw pillows available and provide tips on how to select the perfect size for your furniture and design preferences.

Understanding Standard Throw Pillow Sizes

Throw pillows can be found in many sizes, but some are more common. The most popular size for throw pillows is the 18-inch by 18-inch square pillow. This medium-sized square decorative pillow is versatile and fits well on different types of furniture, from armchairs to sectionals. However, it’s important to note that decorative pillows don’t have strict standard sizes, allowing you the freedom to choose what you like.

Popular Sizes of Throw Pillows

When it comes to throw pillow sizes, you have numerous options to explore. Different throw pillow sizes, charts, and shapes are available to suit various design preferences and furniture arrangements. Let’s take a closer look at some of the most popular sizes for decorative throw pillows:

Square (or Euro Sham) Pillows

Square throw pillows, also known as Euro sham pillows, are the most common shape, and these pillow covers offer versatility and easy stacking. These pillows are available in a range of sizes, including:

  • 16″ x 16″
  • 18″ x 18″
  • 20″ x 20″
  • 22″ x 22″

Square pillows are perfect for mixing and matching patterns and textures, making them a famous choice for adding visual interest to sofas, beds, and chairs.

Round Pillows

Round throw pillows are a trendy option that can add a touch of elegance to your space. These pillows are often used as accent pieces and come in sizes ranging from 18″ to 22″ in diameter. Due to their shape, they are usually used individually rather than being layered with other pillows.

Lumbar (or Body) Pillows

Lumbar pillows are rectangular and larger, making them ideal for supporting your back and spine. These pillows are not only decorative but also serve a functional purpose. Some common sizes for lumbar pillows include:

  • 10″ x 20″
  • 12″ x 20″
  • 12″ x 40″
  • 14″ x 22″

Lumbar pillows are great for adding a layer of extra comfort to your couch or bed, especially if you enjoy lounging or reading.

Bolster Pillows

Bolster pillows are cylindrical in shape and offer a unique and stylish look. They are often used to fill up negative space on long couches or large beds while providing support for tired necks when lying down. Common sizes for bolster pillows include 6″ diameters with 12″ length or 7″ diameters with 20″ length.

Now that we’ve explored the popular sizes of throw pillows, you may be wondering how to choose the right bed pillow size for your specific needs. Let’s consider some factors when selecting a throw pillow size.

Factors to Consider When Selecting a Throw Pillow Size

Choosing the right throw pillow size involves considering a few factors, including the furniture type, layering preferences, decorative pillow sizes, and the purpose of the pillows. Here’s a breakdown of each factor and how it impacts your decision:

Furniture Type

Your furniture type plays a significant role in determining the appropriate throw pillow size. Not every size of throw pillow dimensions fits well with every furniture piece. Consider the following guidelines when selecting throw pillows for different types of furniture:

  • Small Sofas or Loveseats: If you have a petite sofa or loveseat that seats only two people, opt for one lumbar pillow along the seat or stack the corners with one or two Euro pillows.
  • Large Sofas: With ample space on large sofas, you can experiment with different pillow combinations more freely. Mix lumbar, neck roll, and Euro pillows for a varied and visually appealing arrangement. However, avoid overcrowding the space by limiting the number of pillows to one per seat cushion section.
  • Armchair: For a single-seat armchair, stick to a single Euro throw or round pillow. Anything larger may take up too much sitting room and make the chair feel cramped.
  • Bed: The number of throw pillows you use on your bed depends on its size. For a California King-size bed, you can stack a few throw pillows in front of your sleeping pillows. Consider using neck rolls or round designs as centerpieces. A smaller Euro pillow will suffice for a twin bed to fill the space.

Layering

Consider whether you prefer a minimalistic or layered look when it comes to throw pillows. Opt for a single-throw pillow or a small arrangement if you want a touch of decor without overwhelming your furniture. The more throw pillows you have, the smaller the size should be. However, don’t be afraid to mix different shapes and sizes and arrange throw pillows to add texture and visual interest to your space. Just be mindful not to cover all available sitting space with different types of pillows.

Purpose

The purpose of the throw pillows also influences the first pillow size guide that you should choose. If you’re primarily looking for decorative pillows, select dimensions matching the furniture’s space and shape. For example, avoid using massive lumbar pillows on twin beds as they may overpower the bed’s size. On the other hand, if you’re looking for pillows that provide support and comfort, consider using smaller square pillows for style and lumbar pillows on couches or bolsters on beds.
