Selecting the right pillow size is essential to achieving a well-balanced, stylish, and comfortable space. The right pillow sizes can enhance proportions, provide functional support, and create a designer-quality aesthetic.
Whether you're styling a sofa, bed, accent chair, or sectional, follow this in-depth guide to choosing the perfect pillow sizes and inserts for a luxurious and well-proportioned look.
Pillow Size Guide for Every Space
Sofas & Sectionals: The Art of Layering
The key to styling sofas and sectionals is to layer different sizes for depth and dimension.
- 20” x 20” Pillows → The standard size for most sofas. Perfect for a clean, structured look.
- 22” x 22” Pillows → Offers a plusher, oversized look, ideal for deeper sofas.
- 24” x 24” Pillows → Creates a lounge-worthy, inviting aesthetic, best for large sectionals & floor seating.
- Lumbar Pillows (12” x 24” or 14” x 36”) → Add lower back support and a modern touch when layered with square pillows.
Designer Tip: Start with larger pillows at the back (24” x 24”), then layer medium (22” x 22”) and smaller (20” x 20”) pillows in front for a designer-styled look.
Beds: Finding the Perfect Proportions
Your bed should feel plush, inviting, and well-balanced. The right pillow sizes enhance comfort and aesthetics without overcrowding your space.
-
Euro Shams (26” x 26”) → The go-to size for King & Queen beds, providing a polished, structured backdrop.
-
Standard Sleeping Pillows (20” x 26”) → The most common sleeping pillow size, used in pairs for Twin, Queen, or King beds.
-
King Sleeping Pillows (20” x 36”) → Ideal for King-size beds, offering extra width for support.
- Lumbar Pillows (12” x 24” or 14” x 36”) → Adds depth and contrast when placed in front of square pillows, creating a sophisticated, modern aesthetic.
Pro Tip: For a layered, hotel-quality bed, use Euro shams at the back, sleeping pillows in the middle, and a lumbar or accent pillow in front for depth.
Chairs & Accent Seating: The Right Finishing Touch
Pillows in accent chairs, benches, and reading nooks add comfort and style without overwhelming the space.
-
18” x 18” or 20” x 20” Pillows → Ideal for armchairs and accent chairs, adding support and style.
- Lumbar Pillows (12” x 20” or 12” x 24”) → Provide lower back support and a sleek, refined aesthetic for benches, dining chairs, and accent seating.
Pro Tip: For reading nooks or deep chairs, mix a larger 20” x 20” pillow with a lumbar pillow for the perfect combination of style and comfort.
The Golden Rule: Always Size Up Your Inserts!
To achieve a full, plump, and luxurious pillow look, always use an insert that is 2 inches larger than your pillow cover.
-
20” x 20” cover → Use a 22” x 22” insert
-
18” x 18” cover → Use a 20” x 20” insert
- 24” x 24” cover → Use a 26” x 26” insert
Why Is This Important?
- Fills out the cover completely for a polished, high-end look.
-
Prevents sagging and flattening over time.
- Creates a designer-style "chop" effect when fluffed.
For lumbar pillows, inserts 1-2 inches larger in width work best to maintain structure and comfort.
