The volume of buckwheat hulls is approximately 200 cubic inches per pound. We created this pillow fill calculator to help you estimate the volume of your pillow and the required amount of buckwheat hulls to fill it.
How many pounds of buckwheat hulls do you need?
- Due to natural variations, buckwheat hulls are not an exactly consistent volume per pound. The volume of buckwheat hulls can also vary depending on how tightly they are packed. This calculator is for rough estimation only.
- "Average thickness" refers to the thickness of the pillow when completely flattened. Because buckwheat bed pillows have a moldable shape, the functional thickness of the pillow may be several inches thinner or thicker than the average thickness, depending on how you shape the pillow. Most people prefer an "average thickness" between 3 and 4 inches.
- Because buckwheat pillows are often not filled to their maximum capacity, we've provided a a range of the most popular fill levels for tapered pillow shapes. Your preference may vary.
