Determine the ideal washing machine drum size for your household needs.
Total number of people in the household

How We Calculate This
The calculator estimates weekly laundry production based on household size and lifestyle, divides by wash frequency, then recommends a drum size.
Weekly laundry = people x kg per person (adjusted by lifestyle)
Per wash = weekly laundry / wash sessions per week
Drum size = per wash / loading efficiency (rounded to nearest standard size)
