Written by Caroline Chou


Posted on September 18 2023

What are the dimensions of your classic throw pillow, and how do you decorate with multiple sizes of throw pillow to achieve the look you want? Understanding throw pillow sizes is essential to great accessory decoration. Layering a few throw pillows can make any couch more welcoming, and can turn almost any space into a seating area. Throw pillows can be seasonal, comfortable, and even helpful for those with back problems.

But first, you need to know your throw pillow sizes and dimensions so you can plan your seasonal decor down to the last detail.  

The Classic Sizes for Throw Pillows

Throw pillows come in four different standard shapes; square, round, bolster, and lumbar pillows. These pillows each come in a small variety of sizes so that you can layer them elegantly together or in mixed styles.  

  • Square
    • 16" - 24" sides (40.5 cm - 61 cm)
  • Round
    • 14" - 20" diameter (35.5 cm - 51 cm)
    • 3.5 - 4" depth (9 cm - 10cm)
  • Bolster
    • 10" - 30" length (25.5 cm - 76 cm)
  • Lumbar
    • 16" - 36" length (40.5 cm - 91.5 cm)


Square Throw Pillow Dimensions

  • XSmall - 16" x 16" (40.5 cm x 40.5 cm)
  • Small - 18" x 18" (45.5 cm x 45.5 cm)
  • Medium - 20" x 20" (51 cm x 51 cm)
  • Large - 22" x 22" (56 cm x 56 cm)
  • Euro - 26" x 26" (66 cm x 66 cm)

Square throw pillows are by far the most popular and commonly used. From little throw pillows to extra large ones, we respect just how comfy a square throw pillow can be. You may be looking to create a layered living room appearance or make a guest bedroom more cozy. You might be planning to hand-sew your own throw pillow covers, whatever your plans, square throw pillows range from 16x16 inches at the typically smallest (there are always yet smaller pillows) to Euro 26x26 inches at the largest.


Round Throw Pillow Dimensions

  • Small - 14" diameter x 3.5" depth (35.5 cm x 9 cm)
  • Large - 20" diameter x 4" depth (51 cm x 10 cm)

Round throw pillows add a nice touch of shape and diversity to your decor.  They contrast the sharp and even soft right-angle corners in every direction and can even make a space feel more playful or whimsical as a result. Round throw pillows take well to handmade covers and serve a purpose when it comes to comfort. Many people will stack a few round throw pillows into the mix for beauty and relaxation.


Bolster Throw Pillow Dimensions

  • Neckroll - 6" x 16" (15 cm x 40.5 cm)
  • Small - 7" x 10" (18 cm x 25.5 cm)
  • Large - 9" x 30" (23 cm x 76 cm)

A bolster is the round tube-shaped throw pillow that is not quite long enough to become a makeshift lightsaber. Bolster pillows are often used to help other pillows stand up in presentation or to provide rolling support for a stiff calf or shoulder as you relax before bed. Round throw pillows are a favorite for decorators and those with unique orthopedic needs.

You will find bolster pillows in a large 30" style, a smaller 10" style, and the narrower neck roll.


Lumbar Throw Pillow Dimensions

  • Small - 12"  x 16" (30.5 cm x 40.5 cm)
  • Medium - 16" x 20" (40.5 cm x 51 cm)
  • Large - 14" x 36" (35.5 cm x 91.5 cm)

The lumbar throw pillow is also essential for comfort and will be the top favorite throw pillow for certain guests who need extra lumbar support. Include at least one lumbar pillow in your accent decorating design ranging from 16 inches long to 36 inches long. This allows you to choose between individual lumbar pillows, one per furniture piece, or a very long lumbar pillow.
