Laundry Load Size Calculator

How This Tool Works

This calculator determines optimal washing machine load size based on several factors that affect cleaning performance. The tool considers machine type (which affects how clothes move), fabric type (which affects how much space items need), and soil level (which affects water circulation needs).

Proper load sizing is crucial for effective cleaning. Overfilled machines prevent clothes from moving freely, reducing cleaning effectiveness and potentially causing damage. Underfilled machines waste water and energy. This calculator helps you find the sweet spot for each load.

Load Size Guidelines

• Small (50-65%): Delicate fabrics, bulky items, heavily soiled loads
• Medium (65-75%): Mixed loads, normal soil level, some delicate items
• Large (75-85%): Regular cotton loads, normal soil, standard washing
• Extra Large (85-90%): Only for lightly soiled, non-bulky items in large-capacity machines

FAQ

• How full should I fill my washing machine?
  Most washing machines work best when filled 75-85% full. This allows clothes to move freely and water to circulate properly. Overfilling prevents proper cleaning, while underfilling wastes water and energy.
• Does machine type affect load size?
  Yes. Front-load washers can typically be filled slightly more (80-85%) than top-load washers (75-80%) because they use gravity and tumbling action. Compact washers need more space (70-75%) due to their smaller capacity.
• How do I know if my load is too full?
  If clothes are tightly packed with no room to move, the load is too full. You should be able to fit your hand into the drum and move clothes around. Overfilled loads result in poor cleaning, wrinkles, and can damage the machine.
• What about delicate fabrics?
  Delicate fabrics need more room to move (50-65% full) to prevent damage. Items like silk, lace, and fine knits should have plenty of space to tumble gently without tangling or stretching.
• Can I wash bulky items like comforters?
  Bulky items like comforters, blankets, and large towels should fill only 50-65% of the machine. They need extra space to move and absorb water properly. Some very large items may need to be washed alone or at a laundromat.
• Does soil level matter?
  Yes. Heavily soiled items need more room (5-10% less fill) for better water circulation and agitation. Lightly soiled items can be slightly more full, but still within the recommended range.
