What Size Backpack Is Best For Travelling? Choosing the right size travel backpack can feel overwhelming, but TRAVELS.EDU.VN is here to help you find the perfect fit for your next adventure, ensuring a comfortable and stress-free experience. We’ll explore various sizes and features, helping you determine the ideal travel backpack for your needs, whether it’s a weekend getaway or a long-term journey. Looking for the most suitable carry-on luggage or the right capacity backpack for your trip? Consider TRAVELS.EDU.VN your reliable source.
1. Understanding Backpack Sizing for Travel
Backpack capacity is typically measured in liters, a standard unit that makes it easier to compare sizes across different brands. A good rule of thumb is that 25-30 liter backpacks are ideal for weekend trips, while 30-45 liter backpacks are better for longer journeys. According to a survey by Condé Nast Traveler, the average traveler packs for a week-long trip using a 40-liter backpack, highlighting the efficiency of this size. The best backpack size, however, depends on several factors, as we will explore below.
To get a sense of how much a liter equates to, imagine a gallon jug holding about 3.7 liters. Therefore, a 20-liter backpack can hold approximately five and a half gallon jugs. A medium-sized rolled-up t-shirt occupies about one liter of space, meaning you could fit around 20 rolled t-shirts in a 20-liter backpack.
Keep in mind that the capacity of a backpack doesn’t always align perfectly with its dimensions. Capacity tells you how much you can fit, while dimensions give you a better idea of what you can fit. Some 15-liter daypacks might not be long enough for a 13-inch laptop, while others are. Therefore, considering both volume and dimensions is crucial.

2. Factors to Consider When Choosing a Backpack Size for Travel
Selecting the right travel backpack size involves considering several key aspects. Understanding your trip length, destination, and packing style will help you make an informed decision, ensuring you have the ideal travel companion.
2.1 Trip Length Matters
A weekend getaway requires fewer clothes and supplies than a multi-week trip. For longer travels, you’ll need more clothing and toiletries, necessitating a larger bag. Conversely, for shorter trips, avoid carrying an unnecessarily large backpack with empty space. According to a report by the Travel Goods Association, travelers often regret overpacking, highlighting the importance of selecting an appropriately sized backpack for the duration of your trip.
Neo F. shared his experience: “For the last few years, I have been searching for a bag that has the space and durability to travel with while also having the utility to use every day. This is that bag. Series 2 Medium Knack Bag has enough space to hold 3-4 days of clothing and the laptop pocket is awesome. It is highly functional and exactly what I was looking for.”
2.2 Destination Considerations
Traveling with an expandable Knack Pack
Your destination’s climate significantly impacts your clothing choices. Warm, sunny locations allow for lighter clothes that take up less space, enabling you to use a smaller bag. Colder climates necessitate bulkier clothing, requiring a larger backpack. Similarly, business trips demand space for professional attire and technology. Consider all the extras you’ll need, such as cameras, toiletries, and warm socks. Even short trips might require a larger bag to accommodate everything.
2.3 Packing Style Assessment
Are you a minimalist packer who can manage with a few essentials, or a “just-in-case” packer who prefers backups? Your packing style greatly influences the backpack size you need. “Just-in-case” packers should opt for a larger travel backpack. Regardless of your style, creating a packing list can help you stay organized.

3. Optimal Carry-On Travel Backpack Size
The TRAVELS.EDU.VN team prefers traveling with carry-on bags to keep belongings secure, avoid baggage claim lines, and save on checked bag fees. Generally, backpacks under 50 liters or about 22 x 14 x 9 inches are allowed as carry-ons. A 45-liter backpack is ideal for maximizing carry-on space.
Most airlines allow a backpack to be used as a personal item if it fits under the seat in front of you, typically under 20 x 12 x 9 inches. Always check your airline’s website for specific size restrictions to ensure your backpack qualifies as a personal item.
4. Travel Backpacks vs. Outdoor Backpacks: What’s The Difference?
Outdoor backpacks, designed for hiking, typically have a high capacity, starting around 45 liters. While spacious, they are not ideal for general travel. Organizing clothes, tech, and toiletries in deep, top-loading compartments designed for camping gear can be challenging. Accessing items is difficult, and dangling straps can get caught in baggage carousels.
General-purpose travel backpacks feature more pockets for better organization and a more professional appearance for city travel and hotel check-ins.
Raul A. shared his experience: I have taken my Knack Pack on over 20 trips. I arrive at the hotel, empty everything in a drawer, compress the bag, and it’s the perfect computer bag. Caught in a downpour and everything stayed dry inside. Expanded, it fits perfectly under the seat on every flight.”
5. The Versatility of Expandable Backpacks for Travel
An expandable backpack offers the flexibility of additional space when needed, making it an excellent choice for various travel scenarios. According to a survey by Forbes Advisor, expandable backpacks are increasingly popular among travelers for their adaptability and convenience.
5.1 Overnight Trips: 20-30 Liter Backpacks
A 20-30 liter backpack is perfect for overnight trips. The Small Knack Pack, at 15 liters unexpanded, is ideal for carrying daily essentials, while its expandable compartment easily accommodates a day’s worth of clothing.
5.2 Trips of a Few Nights: Medium Knack Pack
The Medium Knack Pack, with 27 liters unexpanded and 39 liters expanded, can hold at least 2-3 days’ worth of clothes. It also fits a 15-inch laptop in a separate pocket. This size is perfect for short business trips or weekend getaways.
5.3 Is a 40L Backpack Big Enough for Traveling?
A 40-liter backpack is generally sufficient for travel, provided you avoid overpacking. Overpacking can be as problematic as underpacking. You don’t want to carry a bulky bag everywhere.
5.4 Longer Trips: Large Knack Pack
The Large Knack Pack, at 30 liters unexpanded and 46 liters expanded, offers ample space for extended trips. It can accommodate a significant amount of clothing and travel essentials.
Jon C. shared his experience: “I was able to make it through 3 weeks in Europe with this bag (and packing cubes) as well as use it for my work” about his Series 1 Large Expandable Knack Pack.
The advantage of an expandable backpack is its dual functionality as a daypack for exploring your destination, eliminating the need for a separate daypack.
