Quick Answer: A 20–30 litre backpack is suitable for many short trips, while 30–45 litres offers more space for longer journeys. The ideal travel backpack depends on your trip duration, packing habits and transport requirements. For air travel, always check your airline’s baggage dimensions and weight limits.
Best Backpack Sizes for Different Trips
Use these approximate capacity ranges to choose a backpack based on your travel plans.
| Capacity | Best For |
|---|---|
| 10–20 L | Sightseeing and day trips |
| 20–30 L | Overnight stays and short city breaks |
| 30–45 L | Weekend trips and minimalist travel |
| 45–60 L | Longer journeys with additional clothing or equipment |
Trip duration isn’t the only factor. A lightweight summer wardrobe requires less space than winter clothing or specialised equipment.
How to Choose a Travel Backpack That Fits Your Needs
- Dimensions: Check the backpack’s height, width and depth in centimetres, especially for flights.
- Comfort: Look for adjustable shoulder straps and a design that sits close to your back.
- Organisation: Separate compartments help keep documents, electronics and clothing accessible.
- Weight: Consider the backpack’s empty weight as well as its packed weight.
Useful tip: Pack versatile clothing and plan to do laundry on longer trips. This can significantly reduce the backpack capacity you need.
Remember that capacity in litres does not guarantee cabin baggage compliance. Measure the fully packed backpack and check your airline’s current restrictions.
