Laundry Washer Load Balance Calculator

Stop washer wobble and harsh vibrations with a precise, engineering-grade load balance tool. Estimate wet mass, fill ratio, and unbalanced force, then get a safe spin-speed limit and smart redistribution tips. Supports fabric mix, moisture retention, drum size, and quadrant placement, so you protect bearings, shorten cycles, save energy, and enjoy quieter, smoother laundry every time, with consistent, reliable results.

Recommendations
  • Reduce spin to 400 RPM or redistribute items across quadrants.
  • Place heavy items opposite one another; avoid all heavy pieces on one side.
  • For front-loaders, mix large and small items to improve tumble balance.
  • Use mesh bags for small items to prevent clumping and improve balance.
  • Consider lowering RPM for delicate fabrics even if balance is good.

Frequently Asked Questions
It’s the effective mass that isn’t evenly distributed around the drum. During spin, this offset creates a centrifugal force, causing vibration and “walking.”
Manufacturers rate capacity using dry cotton. Balance during spin depends on wet mass, so the calculator estimates wet mass from moisture retention percentages.
A very small load may collect on one side of the drum and fail to counterbalance itself, creating a large offset. Add a towel or reduce RPM to help.
Measure the drum’s inner diameter and divide by two. Use centimeters here; the calculator converts to meters for physics calculations.
It depends on balance and machine design. Enter your settings to get an estimated limit. If the machine vibrates, lower the RPM or rebalance.
No. This is an educational tool. Always follow the limits, programs, and guidance provided by your washer’s manufacturer.
Mix large and small items, spread heavy pieces opposite each other, avoid single bulky articles, check feet leveling, and try a lower spin speed.
