A "Medium Suitcase" in 2026 is generally classified as a checked bag and is the most popular choice for a 7-to-10 day trip. Average dimensions are approximately H 67 x W 45.5 x D 26 cm (roughly 24 to 26 inches tall). These bags typically have a capacity of 60 to 80 liters and are designed to hold between 15kg and 23kg (33–50 lbs) of weight without becoming "oversized." In 2026, many brands have optimized these dimensions to sit right at the edge of airline "linear inch" restrictions (usually 158cm / 62in) to avoid extra fees. When measuring, remember to include the wheels and handles, as many 2026 gate sizers now feature height-sensors that include everything from the floor up. If you're packing for a "week-long holiday," a 65–70cm bag is the industry standard recommendation for a comfortable balance of space and portability.
