Throw Pillow Sizes and Arrangements

Throw pillows are not just decorative elements but essential for adding color, texture, and personality to your living space.

Whether you have a sofa or a sectional, arranging throw pillows in the correct sizes and styles can instantly change the look and feel of your room.

This comprehensive guide will explore everything you need to know about choosing the right throw pillows, pillow sizes, and arrangements for a designer look. 

Choosing the Right Size

When throwing pillow sizes, choosing the right size is crucial for achieving a full and visually appealing look. The general rule of thumb is to select bed pillow sizes and an insert that is 2 inches larger than your pillow cover. However, the importance of sizing up varies depending on the pillow size.

Pillow Sizing Chart

Here is a handy pillow sizing chart to help you choose the correct insert for your size bed your pillow cover:

Keep in mind that if you choose a full insert, you may not need to size the bed pillow further up, as your pillow cover may not be able to accommodate the fullness. Additionally, some Etsy vendors create pillow covers that are exactly the right size, so it’s a good idea to check with the vendor for their recommended insert size.

Selecting the Right Insert Fill

The first step in choosing the right throw pillow is selecting the appropriate insert fill size. There are three main types of fill to consider: polyester, down (including down/feather blends), and down alternative. Each type has its characteristics and benefits.

Polyester Inserts

Polyester inserts, also known as polyfil, are made from artificial materials. They are less expensive than down inserts and retain their shape well. However, they are not as malleable and may not be suitable for decorative throw pillows. Polyester inserts are great for providing back support on deep chairs or sofas. You can find them at stores like HomeGoods and Target.

Down Blend Inserts

Consider using down or down blend inserts for a luxurious and full look. Down blend pillow inserts mix down and feathers, providing a fluffy and natural appearance. They can be shaped easily for a more organic look. While down blend inserts are more expensive, they add a touch of elegance to your throw pillows.

Down Alternative Inserts

If you have allergies or prefer a synthetic option, down alternative inserts are great. Despite the name, down alternative inserts are made of clusters of polyester that mimic the feel of down. They are a practical option for those who want the softness of down without the allergens.

Common Throw Pillow Sizes

Throw pillows come in various sizes, from small and dainty to large and oversized. The most common throw pillow sizes include:

1. Small Square (16×16 inches): These pillows are best for adding a touch of color or pattern to a chair or small sofa. They can be used individually or in pairs to create a balanced and cohesive look.
2. Medium Square (18×18 inches): This size is ideal for more giant chairs or small to medium-sized sofas. It provides enough support and comfort without overwhelming the furniture piece.
3. Large Square (20×20 inches): Large square pillows are great for oversized sofas or sectionals. They offer ample back support and create a more substantial and luxurious look.
4. Rectangle (12×20 inches or 14×24 inches): Rectangular throw pillows are perfect for adding visual interest to a bed or a long sofa. They can be placed horizontally or vertically for a different aesthetic effect.
5. Oversized (24×24 inches or larger): These pillows make a bold statement and are best suited for large sofas or spacious seating areas. They are perfect for lounging and adding a touch of drama to your space.
6. Lumbar (12×18 inches or 16×26 inches) – These pillows provide excellent lower back support and are commonly used on chairs, benches, and beds. They add both comfort and decorative appeal. Their elongated shape makes them perfect for layering with square pillows. They are also great for relieving tension when placed behind the lower back.
7. Round (16-inch or 18-inch diameter) – Round throw pillows add softness and variety to a pillow arrangement. They are ideal for breaking up the sharp lines of square or rectangular pillows. Their curved edges create a more relaxed and inviting aesthetic. They work well as accent pieces in bohemian, eclectic, or vintage-styled spaces.
8. Bolster (6×16 inches or 8×24 inches) – Cylindrical bolster pillows provide ergonomic support for the neck or lower back. They are often used on daybeds, chaise lounges, and beds. Their firm structure makes them great for adding definition to a seating area. They are also useful for enhancing posture and reducing strain.
9. Euro (26×26 inches or 28×28 inches) – These large square pillows are commonly used on beds for back support and layering. They create a plush and inviting look when combined with standard pillows. Their generous size makes them a staple in luxurious and hotel-style bedding. They can also be used as oversized floor cushions for casual lounging.
10. Mini Accent (12×12 inches or smaller) – These tiny pillows serve as decorative accents, adding pops of color or texture to a larger pillow arrangement. They are perfect for adding intricate details like embroidery, tassels, or beading. Despite their small size, they can elevate the overall aesthetic by tying in colors or patterns.

Pillow Arrangement – The Winning Formula

Arranging throw pillows on your couch or sectional requires a winning formula that combines both looks and practicality. Here, we will share our favorite arrangement of standard pillows that work well for both.

1. Layering Your Pillows

Regardless of the number and size of pillows you use, layering is key to achieving an interesting and visually appealing arrangement. For a regular sofa, aim for three sizes of pillows: large, smaller, and lumbar. If your sofa is shorter, you can skip the lumbar pillow.

2. Sofa Throw Pillow Arrangement

While there is no one-size-fits-all formula for arranging pillows on a sofa, we recommend the following arrangement as a starting point:

1. Start with two 22″ pillows on each end of the sofa, using 24″ inserts for a complete look.
2. Layer two 20″ pillows in front of the more giant pillows, using 22″ inserts.
3. Place a lumbar pillow in the sofa’s center to add interest and support.

You can adjust this arrangement based on your bed or sofa size. For example, you can use a 20″ pillow with an 18″ insert in front if you have a smaller sofa. Avoid using 24″ pillows on the sides as they may overpower the arms of the sofa.

3. Symmetrical Balance Arrangement

This approach creates a formal and polished look with evenly placed pillows.

• Start with two matching 24″ pillows on each end of the sofa.
• Add two 20″ pillows in front of them.
• Finish with a centered lumbar pillow for support and contrast.

4. Asymmetrical Eclectic Mix

For a more relaxed, modern style, mix up sizes and textures.

• Place a large 24″ pillow on one end and a 22″ on the other.
• Add a smaller accent pillow (18″ or 20″) with a pattern on one side.
• Use an off-center lumbar pillow to balance the design.

5. Monochromatic Minimalist Look

A sleek, understated arrangement with neutral colors and fewer pillows.

• Use two large 24″ pillows at the sofa’s ends.
• Add a single 22″ pillow in a slightly different texture or shade.
• Finish with a long lumbar pillow in the center.

6. Throw Pillow Arrangement for a Sectional

For more oversized sofas like a sectional, the same basic arrangement can be applied with a slight variation for the corner. Here’s a suggested arrangement for a sectional sofa:

1. Place a large 24″ pillow as a backrest at the corner of the sectional.
2. Layer a 22″ pillow in front of the giant pillow in the corner.
3. Add a smaller lumbar pillow to complete the arrangement.

Feel free to customize this arrangement based on your preferences and the size of your sectional couch. You can use a 24″ pillow for the back or replace the smaller front pillow with a short lumbar pillow.

7. Throw Pillow Arrangement For Bed

Creating a well-styled bed requires thoughtful pillow arrangements that enhance both comfort and visual appeal. Here’s a guide to arranging pillows for different bed sizes to achieve a polished and inviting look:

King Bed

For a luxurious and layered appearance, start with a strong foundation at the back and gradually build forward:

• Back Layer: Arrange three large 24-inch square pillows against the headboard for a structured and full look.
• Middle Layer: Position two slightly smaller 20-inch square pillows in front of the larger ones to add depth and variety.
• Front Layer: Complete the arrangement with a long lumbar pillow (typically 14×36 inches) or two cylindrical bolster pillows. These add the finishing touch, introducing a sleek and cohesive design.

Queen Bed

A well-balanced pillow setup for a queen bed follows a similar layering approach but with fewer elements:

• Back Layer: Place two 24-inch square pillows against the headboard for a plush and supportive base.
• Middle Layer: Add two 20-inch square pillows in front to create dimension.
• Front Layer: Finish the look with a decorative lumbar pillow or a round accent pillow to introduce a touch of personality and softness.

Twin Bed

For a neatly arranged twin bed, opt for a more compact yet stylish pillow combination:

• Back Layer: Use a single 24-inch square pillow as the foundational piece.
• Middle Layer: Place a 20-inch square pillow in front to add depth.
• Front Layer: Conclude the arrangement with a single lumbar pillow, which not only enhances the aesthetic but also provides extra support when sitting up in bed.

8. Throw Pillow Arrangement For Chair 

Pillows can enhance both the comfort and aesthetics of chairs, creating a cozy and inviting atmosphere. Depending on the type of chair, the arrangement should be proportionate to avoid overcrowding.

Armchairs

A classic armchair benefits from a simple yet effective pillow setup:

• A single 18×18 or 20×20 square pillow is ideal for providing support without overwhelming the chair’s design.
• For added lumbar support and an extra touch of comfort, consider incorporating a small lumbar pillow in front of the square pillow.

Accent Chairs

Since accent chairs often have distinct shapes and designs, a carefully chosen pillow can add character without dominating the overall look:

• A round or bolster pillow is a great choice, introducing an elegant yet subtle decorative element.
• These shapes complement the contours of the chair while maintaining a balanced and proportional arrangement.

Creating Perfect Pillow Combinations

• Pairing Prints: If you enjoy bold and dynamic designs, pairing two different prints can create an exciting and visually stimulating look. The key is to choose patterns that complement each other without clashing.
  Example: A floral pillow combined with a geometric print pillow in similar colors for a cohesive yet lively arrangement.
• Print with Textured Solid: If you prefer a more balanced and subtle aesthetic, pair a printed pillow with a textured solid pillow. This combination provides contrast while keeping the look grounded.
  Example: A striped or floral print pillow paired with a woven or knitted solid-colored pillow to add depth without overwhelming the space.
• Two Solids with Different Textures: When using two solid-colored pillows, selecting different textures helps maintain visual interest and prevents the arrangement from feeling flat.
  Example: A smooth velvet pillow paired with a chunky knit or linen pillow in the same or complementary color family.
• Layering with Lumbar: A lumbar pillow adds depth and contrast to your arrangement by varying the size and shape of your pillows. It also provides extra support and enhances visual interest.
  Example: Place a large neutral-toned pillow at the back, a patterned square pillow in the middle, and a textured lumbar pillow in the front.
• Monochromatic Mix: Using different shades of the same color creates a sophisticated, cohesive look. Mixing various textures prevents the arrangement from feeling flat.
  Example: Combine deep navy pillows with lighter blue and grayish-blue tones, incorporating velvet, linen, and knit fabrics.
• Bold & Neutral Balance: Pairing a bold, statement pillow with neutral-toned pillows keeps the design visually appealing without feeling overwhelming.
  Example: A mustard-yellow pillow paired with cream and beige pillows creates a striking yet balanced look.
• Seasonal Swap: Refresh your space by changing pillow combinations according to the season. Choose lighter fabrics and colors for summer and warmer, textured materials for winter.
  Example: Spring/Summer: Light linen or cotton fabrics in fresh, pastel, or tropical hues. Fall/Winter: Cozy textures like wool, velvet, or faux fur in deep, warm tones like burnt orange or forest green.
• Metallic Accents: Adding metallic details, such as gold or silver embroidery, sequins, or metallic-threaded fabrics, can bring a touch of elegance and luxury.
  Example: A navy velvet pillow with gold embroidery paired with a neutral cream pillow balances the shimmer.
• Geometric & Organic Mix: Mixing structured patterns like stripes or grids with organic shapes like florals or abstract designs adds visual interest while maintaining harmony.
  Example: A black-and-white striped pillow paired with a floral or watercolor-style pillow creates an eye-catching contrast.
• Boho Chic Layers: Mixing textures, patterns, and shapes creates a relaxed and eclectic bohemian style. Incorporate fringe, tassels, or woven details for extra dimension.
  Example: A fringed ivory pillow, a bold Aztec-print pillow, and a small leather or suede lumbar pillow create a warm, layered look.
• Contrasting Shapes: Using different pillow shapes, such as round, bolster, or asymmetrical designs, adds variety and prevents the arrangement from looking too uniform.
  Example: A round velvet pillow placed in front of square ones or a bolster pillow layered between larger pillows creates a more dynamic setup.

DIY throw pillow size customization

If you can’t find the perfect throw pillow size or want to add personal touch-size pillows, consider customizing them yourself. Here’s a simple DIY guide to customizing throw pillow sizes:

1. Choose the fabric: Select a fabric that complements your decor and desired pillow size. Ensure you have enough fabric to cover the pillow form and allow seam allowances.
2. Cut the fabric: Using a measuring tape and fabric scissors, measure and cut the fabric according to your desired pillow size. Remember to add extra inches for seam allowances.
3. Sew the fabric: Place the pieces on the right sides together and sew around three sides, leaving one side open to stuff the pillow form. Utilize a sewing machine or hand-sew for a secure seam.
4. Stuff the pillow: Insert the pillow form into the fabric cover through the open side. Ensure the pillow is evenly distributed, and adjust the stuffing if necessary.
5. Close the pillow: Use a needle and thread or a sewing machine to close the open side of the pillow cover. Ensure the stitches are secure and hidden for a polished finish.
