Best 40L Backpacks for Women FAQs
How Big is a 40L Backpack?
Alright, let’s get into some nitty-gritty details. A 40L backpack typically measures around 21-24 inches in height, 13-16 inches in width, and 8-10 inches in depth. These dimensions make it a good choice for a carry-on backpack, meeting most airline size restrictions.
A 40L backpack strikes the ideal balance between being spacious enough for multi-day trips yet compact enough to remain lightweight and easy to carry. Many travelers will choose a 40L backpack carry-on over a 50L to 60L backpack because it meets most airline size restrictions while offering enough room for clothing, gear, and essentials. This size is perfect for minimalist travelers, weekend getaways, and those who prefer to pack light. Packing is an art, and you will only pack as big as the pack, so if you want to practice minimalism, this is a good way to do it.
For hikers, a 40L trekking backpack offers enough space for overnight gear, a hydration system, and layers without the bulk of larger packs – although we would recommend selecting a backpack that has a breathable bag system and proper straps. We would recommend brands like Osprey, Deuter, and Patagonia as they offer durable options designed to distribute weight evenly, reducing strain on the back and shoulders.
How Much Can You Fit in a 40L Backpack?
A 40L backpack can fit around a week’s worth of travel essentials if packed efficiently. Use compression packing cubes to organize clothes, and roll your clothing to maximize space. For backpacking, prioritize multi-functional gear, such as quick-dry clothing, a microfiber towel, and compact sleeping bags, to save room.
To prevent discomfort, distribute weight wisely by placing heavier items close to your back and at the bottom of the pack. Trust us – a little extra care when packing can save you in the long run. The Fairview 40L backpack Osprey is a suitcase opening, making it very easy to pack, but a more classic 40L backpack travel bag can also meet your needs for compartments and accessibility. With the right approach, a 40L backpack can offer surprising versatility for both short and long-term travel. A great resource on multi-day hikes and backpacking is Osprey’s Complete Guide to Backpacking.
How Much Can You Fit in a 40L Backpack?
A 40L backpack can generally hold enough gear for months if you like! Here is a very basic guide on how we would pack for a two-week trip:
- 3-5 day outfits – think capsule wardrobe that you can mix and match combinations
- 1 night outfit
- A pair of shoes
- A second pair of shoes, depending on the season
- Flip flops (for communal showers)
- Toiletries
- A small laptop or tablet
- Travel essentials (passport, chargers, etc.)
How to Pack a 40L Backpack Efficiently
- Use packing cubes (compressible packing cubes work best) to maximize space and keep items organized.
- Roll your clothes to save space and prevent wrinkles.
- Distribute your weight evenly, placing heavier items closer to your back for better support.
- Keep frequently used items in external pockets for easy access.
Is a 40L Backpack Carry-On Size?
Yes, most 40L backpacks meet airline carry-on size requirements, but it’s always best to check the airline’s regulations, as some allow only under 40L backpacks. Always do your research before you fly.
A 40L backpack for women is the perfect balance between size and functionality, offering enough space for extended travel while still being lightweight and manageable. Whether you need an Osprey 40L backpack, a Decathlon 40L backpack, or a waterproof 40L backpack, there are plenty of great options to suit your travel and adventure needs.
