Best Outdoor Pillow Sizes

OUTDOOR PILLOW SIZES GUIDE

Choosing the right outdoor pillow size is just as important as selecting the right fabric or color. Pillow size affects not only comfort, but also the overall look and scale of your patio furniture. Smaller pillows work well for dining chairs and accent layering, while larger pillows create a more substantial, tailored look on deep seating sofas and sectionals. Mixing sizes—such as square and lumbar pillows—adds dimension and balance to your space. Whether you’re designing a clean, modern layout or a more layered, decorative arrangement, selecting the right pillow sizes will help bring everything together.

Best Uses Of Common Pillow Sizes

SQUARE OUTDOOR PILLOWS

Square outdoor pillows are the foundation of nearly every well-designed patio setting—often considered the “queen” of pillow sizes for their versatility, balance, and timeless appeal. Their symmetrical shape works effortlessly across all types of outdoor furniture, from dining chairs and lounge chairs to deep seating sofas and sectionals. Whether used alone for a clean, tailored look or layered in multiples for a more styled arrangement, square pillows provide the structure and scale that anchor the entire design.

What makes square pillows so essential is their ability to adapt. Smaller sizes offer a subtle, refined accent, while larger squares create a more substantial, relaxed feel suited for deep seating and lounge environments. They pair naturally with lumbar pillows and specialty shapes, making them the starting point for most pillow combinations. No matter the style—classic, modern, or somewhere in between—square outdoor pillows bring comfort, cohesion, and a finished look to any outdoor space.

18" Square Outdoor Pillows

A versatile, smaller-scale pillow that works well on dining chairs, smaller patio chairs, and as a layering piece on larger seating. The 18" square is ideal when you want a clean, tailored look without overwhelming the furniture. It is also commonly used in sets for a more uniform appearance.

20" Square Outdoor Pillows

One of the most popular and versatile outdoor pillow sizes. The 20" square works across a wide range of patio furniture, from standard seating to medium-depth sofas. It offers a balanced look—large enough for comfort, but not oversized—making it a go-to choice for both standalone use and layered arrangements.

22" Square Outdoor Pillows

A larger, more substantial pillow designed for deep seating and more spacious patio furniture. The 22" size adds visual weight and comfort, making it ideal for sofas, sectionals, and lounge chairs where a fuller look is desired.

24" Square Outdoor Pillows

An oversized pillow best suited for deep seating, sectionals, and luxury outdoor furniture. The 24" square creates a plush, high-end look and is often used as a back layer when styling multiple pillows. This size is considered a “large outdoor pillow” and is perfect for creating a relaxed, lounge-style setting.

Square Outdoor Pillows – Custom Sizes Available

While the sizes shown represent the most popular options for outdoor pillows, all of our square pillows are custom made to order. This means we can create virtually any size you need to fit your furniture, design vision, or specific space requirements. Whether you’re trying to match an existing pillow, accommodate unique furniture dimensions, or achieve a perfectly scaled look, custom sizing allows for a more tailored and intentional result.

LUMBAR OUTDOOR PILLOWS

What Is a Lumbar Pillow?

A lumbar pillow is a rectangular-shaped pillow designed to provide support to the lower back, or “lumbar” region of the spine—hence the name. While it serves a functional purpose by improving comfort and posture, it has also become a key design element in both indoor and outdoor spaces. Its elongated shape makes it ideal for layering with square pillows, adding structure, contrast, and a more finished, designer look to patio furniture.

14" x 20" Lumbar Outdoor Pillows

A compact lumbar pillow that provides subtle back support while maintaining a streamlined appearance. This size works well on dining chairs, smaller seating, and as a secondary layer in a pillow arrangement.

12" x 24" Lumbar Outdoor Pillows

One of the most popular lumbar sizes for outdoor furniture. The elongated shape makes it ideal for both support and styling, especially on deep seating sofas and sectionals. The 12" x 24" lumbar pillow adds structure and contrast when paired with square pillows.

Lumbar Pillows – Custom Sizes Available

While the sizes shown reflect the most popular lumbar options, all of our lumbar outdoor pillows are custom made to order. We can produce virtually any length or height to suit your furniture, whether you’re coordinating with a specific sofa, bench, or sectional, or trying to achieve a precise layered look. Custom lumbar sizing is especially helpful when working with deep seating or longer spans, allowing you to create balanced proportions, consistent spacing, and a more tailored, finished design.

BOXED OUTDOOR PILLOWS

Boxed square outdoor pillows offer a more structured, tailored look compared to traditional knife-edge pillows, making them a popular choice among the design trade and for more refined outdoor spaces. Unlike standard pillows, the boxed construction includes side panels that add depth and dimension, allowing the pillow to hold its shape and sit more upright on furniture. This creates a cleaner, more architectural appearance that pairs especially well with high-end patio furniture, deep seating, and modern outdoor designs.

In addition to their visual appeal, boxed square pillows provide a more substantial feel, offering both comfort and support while maintaining a crisp, finished look. They are often used to create a layered, designer-inspired arrangement, either as a statement piece on their own or combined with lumbar and other accent pillows. As outdoor spaces continue to evolve into true extensions of the home, boxed pillows are becoming a go-to choice for achieving a polished, indoor-quality aesthetic outdoors.

20" Boxed Square Outdoor Pillows

A structured version of the standard 20" pillow, featuring added depth for a more substantial feel. Ideal for upscale patio furniture where a more refined, tailored appearance is desired.

17" Boxed Square Outdoor Pillows

A slightly smaller boxed option that works well for more compact seating while still providing structure and definition. Great for chairs or tighter spaces where a full 20" boxed pillow may feel oversized.

DECORATIVE & SPECIALTY PILLOWS

Decorative and specialty pillows are where function takes a back seat to creativity and personal style. While our current offering includes the ball pillow as a standout accent, the possibilities go far beyond—unique shapes, custom sizes, and one-of-a-kind details can all be designed to complement your space. When it comes to specialty pillows, the sky truly is the limit, allowing you to add a distinctive, unexpected touch that sets your outdoor design apart.

CHAISE LOUNGE HEADREST PILLOWS

Chaise lounge headrest pillows are a simple upgrade that makes a noticeable difference in both comfort and appearance. Designed to support the neck and head, they turn a standard chaise into a more relaxing, lounge-worthy experience—whether you’re by the pool, on a patio, or in a backyard retreat. Available in both contoured and rectangular styles, headrest pillows can be tailored to different chaise designs while maintaining a clean, streamlined look.

While ideal for residential use, chaise headrest pillows are especially popular in multi-family communities, hotels, country clubs, and resort settings, where comfort and presentation matter equally. They offer an easy way to refresh or update the look of existing chaises without replacing the full cushion set. Adding headrest pillows introduces a layer of polish and customization, helping create a more elevated, cohesive poolside environment that feels intentional and thoughtfully designed.
