Large suitcases come in sizes of 20 inches, 22 inches, 24 inches, 28 inches, and 30 inches. Detailed specifications: The maximum size for a suitcase is 32 inches, with a height of 98 cm, width of 62 cm, and thickness of 35 cm. However, dimensions may vary slightly between different brands. Material details: Suitcases can be categorized by material into soft fabric suitcases and hard suitcases (hard suitcases can be further divided into ABS, PP, ABS+PC, and pure PC materials). Based on different structures, suitcases can be classified into upright pull rod suitcases and horizontal suitcases (upright suitcases can be divided into four-wheel and two-wheel types).

As a frequent traveler who often jets around the world, I pay special attention to the size specifications of large suitcases. Large suitcases generally refer to sizes ranging from 28 to 32 inches. Common specifications include: 28 inches with a height of approximately 71cm, width of 50cm, depth of 30cm, totaling 151cm in combined dimensions; 30 inches with a height of about 76cm, width of 54cm, depth of 32cm, totaling 162cm; and 32 inches possibly reaching around 81cm in height. However, the standard airline limit for combined dimensions is 158cm, so 30-inch suitcases often exceed this and incur additional fees. When choosing a suitcase, I recommend the 28-inch size because it's a safe bet for packing more—like fitting in clothes while still leaving extra space. Weight is also crucial; exceeding 23kg can double your check-in fees. Brands like Samsonite offer precise dimensions, but soft-sided suitcases can expand, taking up more space. Always check the airline's official website before departure to avoid unexpected charges.

Every time I buy a suitcase for my family, I have to carefully check the size specifications. Large suitcases range from 28 to 32 inches: Samsonite's 28-inch model is approximately 70x50x30cm with a total of 150cm; Diplomat might be 70x52x32cm=154cm; American Tourister's 30-inch model can reach 75x55x34cm, exceeding 162cm. The key is to ensure the total does not exceed the airline limit of 158cm to avoid extra fees during check-in. The weight of the suitcase itself is also crucial, as a heavy case leaves less room for cargo. In terms of material, hard-shell cases are precise, while soft-shell cases are more flexible but prone to exceeding size limits. It's advisable to measure the storage space for the suitcase and consider airline rules before purchasing to avoid future hassles.

When I was a new traveler, I explored the dimensions of large suitcases: standard large sizes like 28 inches with a height of 70cm, width of 50cm, and depth of 30cm; 30 inches with a height of around 76cm. The total sum of the three sides should not exceed the limit of 158cm. When choosing a suitcase, consider the size chart to match and avoid penalties.
