Choosing A Suitcase Size

Cabin Suitcase

  • Cabin suitcases can be carried onto a plane with you as long as they meet the size requirements of the airline you are travelling with.
  • A cabin case is lightweight and easy to manoeuvre with the added benefit of not having to check it in, so you don’t have to wait for it at the baggage belt when you land.
  • You will be limited for space, so a cabin suitcase is only really suitable for a long weekend or a light traveller, or as additional luggage on top of your checked case.

Suitcases To Check In

Before you travel, it’s important to ensure you have packed in line with your airline’s baggage allowance and restrictions, to avoid fees at the airport.

As a general rule suitcases should not exceed a total linear dimension of 140cm and may weigh between 15kg to 32kg for each piece of luggage in Economy Class. First and Business Class are generally allowed extra pieces. Suitcases that weigh over the limit may be subject to an additional fee.

Medium Suitcase

  • Going on a 1 week trip? The perfect sized case for travellers wanting a smaller, lightweight luggage option to check in.
  • Offering around double the capacity of hand luggage, these suitcases are in the 60-69cm range, giving you a good packing capacity yet still fairly compact in size.
  • Whether you are going away for a week or 10 day holiday, or you are packing one bag between two of you for a week or less, a medium suitcase is a good size option.

Large Suitcase

  • Going away for a fortnight? You may need more clothes and accessories so a larger case will be a good option.
  • The most commonly bought size suitcase, it is perfect for multiple travellers, families and those that travel with children.
  • This size is good for a 2 week family holiday.
  • Large suitcases are 70 to 79 cm or 27 to 31 inches in height. They have a capacity of 55 L up to 140 L.
  • A large suitcase is also a good idea if you are planning on shopping while you are away. More room to pack your purchases!

  • The largest suitcases are up to 86cm and provide 144 litres of volume, perfect for 3 weeks or more travelling.
  • Also handy when moving house or overseas.

How To Measure A Suitcase

  • If your suitcase has an expandable width, expand it before measuring so you know its maximum size.
  • Pack your case before measuring as the contents can bulk it out over the allowed depth measurements.
  • Height measurements are for the case stood ‘upright’.
  • Measure the height from the wheels to the top of the retracted handle.
  • Depth needs to be measured from the back of the suitcase to the side that opens.
  • Width is measured across from one wheel edge to another, including any side handles.
  • Don’t forget to check weight allowance too.

Top Tips For Choosing A Suitcase Size

  • Always opt for the smallest suitcase you can use.
  • Don’t buy a big suitcase if you don’t really need to.
  • Don’t overpack or pack things you really won’t need. You can always buy when you’re there.
  • If you’re travelling with someone else, consider sharing a suitcase.
  • If you are travelling in the winter, buy a bigger suitcase to fit jumpers, coats, boot in.
  • If you know you have access to a washing machine on holiday, you don’t need to pack that many clothes.
  • If your airline ticket doesn’t include a checked bag, consider just taking a carry on cabin case if possible.
  • If you’re travelling alone buy a small suitcase.
