# Washing Machine Load Size: An Easy Reference Chart

## The Amount of Laundry Is Based on Drum Capacity

One of the key factors in ending up with truly clean laundry is not to overload the washer. If the washer tub is jam-packed, some clothes will have limited exposure time to the cleaning solution and come out with their original stains and odor. Your washer machine size chart should let you know the capacity of your washer so you don't overstuff it.

If you have lost your washing machine manual and you need to know the capacity of your washer tub, it is simple to calculate. This is also helpful if you want to replace an older machine with one with the same washing capacity. Determining your washer's capacity will also help you know how many clothes it should hold in every load to get good results.

Below are some guidelines to help, including how to calculate the washer tub size, the weight of your dirty laundry, and more.

## The Formula to Calculate Tub Capacity of a Washer

Use this equation to calculate the volume or holding capacity of the washing machine tub; assuming all measurements are in feet.

Equation: Volume (cu. ft.) = pi × r × r × D

For the equation, follow this key:

• pi = ~3.14
• r = radius (feet); remember r = diameter divided by two
• D = depth (feet); in classic geometrical terms the height of the cylinder
• Note: The units result in (cu. ft.). ft × ft × ft = cubic feet.

## How to Calculate the Tub Volume or Capacity of a Washer

1. Make all measurements in feet.
2. Measure the radius of the tub; from the center of the tub to the outside wall of the tub. Alternatively, measure the diameter and divide by two. This is the radius.
3. Using the formula, multiply the radius by the radius; note this is not the same as multiplying the radius by two. This is equivalent to the radius squared.
4. Multiply the radius squared from step three above by pi (3.14).
5. Multiply the value from step four by the depth of the tub to find the cubic feet volume or capacity of the washer.

## Load Capacity by Washer Size

If you are searching for a new washer, different styles are sold with the capacity listed in cubic feet. Now that you know the size of your washer drum, you can figure out how much laundry it will hold in each load. Remember, while it is economical in both utility costs and time management to do full loads, you should never cram clothes and overstuff a washer just because you can. Always check your manual to see specifics for your model washer, but here is a washing machine load size chart with average load capacities for various size washers.
