Listings show a range of handle lengths—from shorter handles around 3.7 inches up to extended handles about 17–20.6 inches—and many products note hanging holes or easy-grip handles for convenient storage.
Collapsible and expandable strainers fold flat to much smaller heights; examples show collapsed heights around 1 to 1.7 inches. Product notes state this can reduce required storage space substantially—one listing cites savings of over 70%.
