Common Sizes for Microwavable Heating Packs (Manufacturer's Perspective)

We typically categorize and produce microwavable heating packs based on their intended use and fill capacity. Here are the common size classifications:
Small / Personal Size (100g - 200g)
Dimensions: Often rectangular or contoured, approx. 15cm x 10cm (6" x 4").
Primary Use: Targeted relief for small areas like wrists, elbows, neck, or sinuses. Ideal for personal, on-the-go use.
Medium / Standard Size (300g - 500g)
Dimensions: Commonly a larger rectangle or square, approx. 20cm x 15cm (8" x 6") or 25cm x 15cm (10" x 6").
Primary Use: Our best-selling size. Versatile for shoulders, lower back, abdomen, and knees.
Large / Body Wrap Size (750g - 1000g+)
Dimensions: Long and flexible, often as a wrap or a large pad. Approx. 30cm x 20cm (12" x 8") or longer wraps up to 75cm (30").
Primary Use: Designed for larger muscle groups, such as wrapping around the back, thighs, or across the abdomen.
Specialty / Animal Toy Size (Varies)
Dimensions: Often smaller and shaped like animals (e.g., 20cm long). Fill weight is usually lighter, around 150g - 300g.
Primary Use: Marketed as comforting toys for children or pets. The shape is a key selling point.

Key Consideration: The exact dimensions can vary based on the filling material (e.g., rice, flaxseed, clay beads) and the fabric design. The weight of the filling is a more consistent indicator of size and heat retention capacity for manufacturing specifications.
