An M-size suitcase generally has a capacity of around 50-70 liters and is suitable for short to medium-term trips (around 3-7 nights). It is between the S-size (suitable for carry-on luggage) and the L-size (for long trips), and is often used as checked baggage.
The exact dimensions will vary depending on the manufacturer and brand, but as a guideline they are generally 60-65cm high x 40-45cm wide x 25-30cm deep (external dimensions including casters and handles), with the total of the three sides being around 140-158cm.
