Bolster pillows are versatile cylinders often used for armrests, back support, or aesthetic accents. Measuring is simple: we only need the Length and the Diameter.

Step 1: Length Side View Step 2: Diameter End View

Step 1: Pillow Length

Measure the long side of the bolster from end seam to end seam.

(This is sometimes referred to as the width, depending on how you place the pillow.)

Step 2: Pillow Diameter

The diameter is the "height" or thickness of the circular end.

We offer bolsters in diameters from 8 to 12 inches, adjustable in 1-inch increments.

⚠️
Measure the Straight Line:
Measure straight across the flat circular face (from top edge to bottom edge).
Do NOT measure the circumference (the distance all the way around the circle).

Measuring Tips

 1-Inch Precision

Bolster dimensions are adjusted in 1 inch increments. Please round your measurements to the nearest whole inch.

 Use Rigid Tools

Use a carpenter's tape measure or ruler. Flexible tailor's tape can bend and distort straight-line measurements.

 Common Sizes

For armrests on daybeds, an 8" or 9" diameter is standard. For back support on deep sofas, 10" to 12" provides better height.

 Diameter vs Height

When you see "Height" listed for a bolster, it refers to the Diameter (the circle size), not the length.
