How to Measure Your Drum
Detailed Measurement Guide
Accurately measuring your washing machine drum is crucial for precise volume calculation. Follow these steps:
1. Measuring Drum Radius (r)
The radius is the distance from the center of the drum to its inner wall. It’s often easier to measure the diameter first and then divide by two.
- Open your washing machine door/lid.
- Measure the widest internal distance across the drum (diameter). Ensure you measure from the inner surface to inner surface.
- Divide this diameter by 2 to get the radius (r).
2. Measuring Drum Depth (D)
The depth is the internal length of the drum from front to back (for front-loaders) or top to bottom (for top-loaders, though this calculator assumes a cylindrical shape).
- For front-loaders: Measure from the inside of the front drum wall to the inside of the back drum wall.
- For top-loaders: Measure the internal height from the bottom of the drum to just below the agitator (if present) or to the top edge of the drum.

Typical Washing Machine Capacities Guide
Understanding drum volume helps you choose the right washing machine for your needs. Here’s a general guide:
- 1.5 – 2.5 cu ft (42 – 70 L): Ideal for singles or couples, small loads, delicates.
- 2.5 – 3.5 cu ft (70 – 99 L): Standard size for small families (3-4 people), handles everyday laundry well.
- 3.5 – 4.5 cu ft (99 – 127 L): Good for medium to large families (4-6 people), can handle blankets and quilts.
- 4.5 cu ft and above (127 L+): Extra large capacity for large families, bulky items like king-size comforters, sleeping bags.
Note: These are general guidelines. Actual capacity can vary slightly by manufacturer and machine type.
