Obtain Dryer Drum capacity

What is the Whirlpool Duet / Duet Sport Dryer YWED9450WW0 drum capacity?

Dryer Drum Capacity as per Manufacturer Specifications (in cubic feet):

We do not have the drum capacity for this model in our database yet but we can try to research it for you, please send us a message with your request.

Calculate Dryer Drum capacity

This is a geometric method to calculate drum capacity based on the cylinder volume formula. Unfortunately, the value could be as much as 25% off from the manufacturer stated capacity.

Why? Because a drum is not exactly a cylinder. The edge where bottom connected to the wall is not at 90 degree angle but smooth and rounded. The end of the drum is not clearly marked and the back is not always flat. Finally, there are baffles inside the drum used for tumbling clothes.

This method can be used as a crude estimate but we do not recommend using it for comparisson when shopping for a new dryer.

To determine your dryer drum capacity please take two simple measurements:

Dryer Drum Capacity Measurements

1. Use the ruler to measure the depth of the drum (indicated by the red line on the diagram)

2. Now find the distance accross the drum, the diameter (the green line on the diagram). Do not confuse the size of the the door opening with the size of the drum. In this case make the measurements INSIDE the drum.


Dryer Drum Depth: in. Dryer Drum Diameter: in.


The Whirlpool Duet / Duet Sport Dryer YWED9450WW0 drum capacity is ... cubic feet.

Make sure to use the manufacturer's part number when ordering a replacement.
