I. Key Factors to Consider When Choosing 20L or 30L
When deciding between a 20L and 30L backpack, understanding how you'll use the backpack, your body type, and the load you'll carry are essential. Let's break down each factor in more detail.
1. Usage:
-
Daily Commuting:
- 20L Backpack: A 20L backpack is perfect for daily commuters who only need to carry the essentials, such as a laptop, charger, small notebook, water bottle, and maybe a lunch. It keeps you light on your feet and ensures you won’t overpack, which is ideal for short commutes and city living where space is tight.
- 30L Backpack: If your daily routine includes gym sessions, bringing multiple changes of clothes, or if you're the kind of person who prefers to be over-prepared (extra jacket, snacks, or even a book or two), a 30L will better suit your needs. It offers enough room for all the extras while still maintaining a reasonable size for everyday use.
💡 Expert tips: Larger backpacks can become uncomfortable if they're not filled properly. Opt for a size that matches your typical daily load. If you often find yourself carrying more than expected, a 30L might be more versatile.
-
Photography:
- 20L Backpack: Ideal for minimalist photographers. It fits a camera body, a couple of lenses, and small accessories like memory cards and batteries. For quick shoots or city photography where you want to stay nimble, a 20L works like a charm.
- 30L Backpack: If you’re a professional or hobbyist photographer needing multiple lenses, a drone, a tripod, or extra batteries, the 30L offers the capacity to bring all your gear without feeling cramped. It's great for more complex photo sessions, whether you’re hiking into nature or covering a full event.
💡 Expert tips: Professional photographers benefit from larger bags that offer better internal organization and padding for fragile gear. If photography is your main focus, 30L will give you peace of mind that nothing is left behind.
-
Travel:
- 20L Backpack: If you're flying or going on short day trips, a 20L serves as the perfect personal item. It’s small enough to fit under your seat while still holding essentials like a tablet, snacks, and some light clothing or accessories.
- 30L Backpack: For weekend getaways or short business trips, a 30L backpack acts as the perfect carry-on. It provides enough room for clothes, toiletries, a small laptop, and travel accessories. Plus, you won’t have to worry about checking in a bag.
💡 Expert tips: Many airlines accept 30L backpacks as carry-ons, but be mindful of overpacking. A fully stuffed 30L can become heavy and harder to manage, so ensure it fits your travel style.
2. Body Frame:
-
Smaller Frame:
- 20L Backpack: If you're petite or have a smaller body frame, a 20L backpack is ideal. It sits comfortably on your back without being too bulky or awkward to wear. Smaller bags are also less likely to strain your shoulders or back, especially if you're carrying it for long periods during commutes or short hikes.
💡 Expert tips: Backpacks that match your frame are important for comfort. Overloading a small frame with a large bag can cause poor posture and strain.
-
Larger Frame:
- 30L Backpack: For taller or larger individuals, a 30L backpack will likely feel more natural. The added length of a 30L distributes the weight more evenly, helping you avoid shoulder strain. If you have broader shoulders or a long torso, the 30L will fit better and feel more balanced.
💡 Expert tips: Taller users often find that 20L backpacks sit too high or awkwardly on their back, which can lead to discomfort. A 30L tends to match a taller build better, especially for extended wear.
3. Load Capacity:
-
20L Backpack:
- If you’re looking to carry the basics—like a laptop, a change of clothes, and maybe a book—then the 20L is the perfect size. It’s compact and forces you to prioritize what you really need. This can be great for efficiency and avoiding the temptation to overpack. The 20L is also great for shorter trips or those who prefer to travel light.
💡 Expert tips: Minimalism forces focus. Packing light with a 20L makes you think critically about your gear and helps you stay organized. It's the ideal size for someone who doesn’t need much but wants to stay efficient on the go.
-
30L Backpack:
- A 30L backpack is ideal for those who need to carry bulkier items or extra gear. Whether you’re carrying camera equipment, clothing for multiple days, or heavier tech gadgets, the 30L ensures you have enough space without having to compromise on what to bring. The increased volume also means you can pack bulkier items like jackets, shoes, or larger laptops.
💡 Expert tips: A fully-loaded 30L backpack can be heavy, but it’s designed to handle it. Look for models that feature ergonomic designs or padded straps to help distribute the weight evenly across your shoulders and back, reducing strain even when the bag is full.

II. 20L Backpack: Pros and Cons
Pros:
-
Lightweight and easy to carry for daily activities: A 20L backpack is designed to be light and highly portable, making it perfect for daily use. Whether you’re commuting to work or running errands, its smaller size means you won’t feel weighed down by unnecessary bulk, which helps reduce shoulder and back strain. Ideal for minimalists and those who prefer quick, efficient movement.
-
Compact size, perfect for navigating busy city environments or tight spaces: The compact nature of a 20L backpack allows for greater maneuverability, especially in crowded areas like public transport, busy streets, or while cycling. Its size makes it easier to store under seats, in overhead compartments, or in small office lockers.
-
Minimalistic design that forces users to pack only what they need: One of the greatest benefits of a 20L backpack is that it encourages a streamlined approach to packing. You won’t be tempted to bring unnecessary items, which means better organization and less clutter. This minimalist design can make your daily routine more efficient by focusing on essentials like a laptop, small personal items, and a light jacket.
Cons:
-
Limited space for extended trips or larger tech: While perfect for daily commutes, a 20L backpack struggles with bulkier items, extended trips, or situations that require packing more than a day's worth of essentials. It’s not well-suited for carrying extra layers, large cameras, or extra tech equipment.
-
May not fit larger laptops or multiple devices: If you have a larger laptop (over 15 inches) or need to carry several gadgets, a 20L may feel cramped. It lacks the extra compartments or space necessary for carrying larger tech items along with chargers, notebooks, and other accessories.
💡 Expert tips:
- Efficiency for minimalists: Minimalists will love the 20L size because it forces you to focus only on what’s essential. By sticking to the basics, you avoid unnecessary bulk, and this can actually improve how you move through your day. Whether you’re commuting, taking a short trip, or attending meetings, the smaller, organized space helps keep everything manageable.
III. 30L Backpack: Pros and Cons
Pros:
-
More storage options and compartments for better organization: A 30L backpack typically comes with multiple compartments, making it easy to organize various items—whether you're packing work documents, electronic devices, or travel essentials. You can keep things neatly separated, which is especially useful for professionals who need to access different items quickly without digging through a cluttered bag.
-
Excellent for travel and professionals who need to carry large equipment or clothes: For those who travel frequently or need to carry professional gear like cameras or laptops, the 30L size is ideal. It offers enough space for extended trips or for packing bulkier items like jackets, shoes, or tech equipment. If you're flying, a 30L backpack is often large enough to serve as carry-on luggage, yet still compact enough to avoid checking a bag.
-
Provides room for bulky items like jackets, shoes, or camera equipment: The additional space in a 30L pack allows for items that a smaller bag would struggle to accommodate. You can easily pack bulkier clothing, shoes, or tech gear like drones, cameras, and lenses, making it a great choice for photographers, travelers, or anyone who needs to bring extra items.
Cons:
-
Bulkier and heavier, which might be uncomfortable for shorter individuals: While the extra storage is convenient, a 30L backpack can feel oversized or too heavy for people with smaller body frames. The added weight, especially when fully packed, might cause discomfort over time, especially if you're carrying it on long walks or during commutes.
-
Takes up more space when commuting in crowded environments (e.g., public transport): A 30L backpack can be cumbersome in crowded spaces like subways, buses, or busy city streets. The extra bulk makes it harder to move around or store under tight seats, and it may take up more room than desired in cramped environments.
💡 Expert tips:
- For photographers or content creators: The 30L size is perfect for creatives who need to bring along multiple pieces of equipment like cameras, lenses, tripods, and even drones. It ensures you don’t have to leave any essentials behind while offering the space and organizational structure needed to protect your valuable gear from damage.

IV. Scenarios for Choosing 20L vs. 30L
1. Daily Commuting:
-
Opt for 20L if you only need a laptop, lunch, and a few essentials: For daily commuting, the 20L backpack is perfect if you're only packing light items. A laptop, lunch, a small notebook, and perhaps a charger can easily fit. Its compact size ensures comfort while commuting on public transport or walking, without feeling too bulky. It’s ideal for urban workers or students with minimal carry needs.
-
Choose 30L if you need to carry gym clothes, lunch, and work documents: If your day involves more than just a few items, like gym clothes, an extra pair of shoes, or a larger laptop, a 30L backpack is a better choice. It offers more room for a larger range of items and compartments to organize everything. This size is also useful if you carry work documents, a water bottle, or other bulkier items.
2. Photography:
-
Choose 30L for full professional gear, including cameras, lenses, and accessories: For photographers, a 30L backpack provides the necessary space for multiple camera bodies, lenses, tripods, and other accessories like batteries or memory cards. This larger size ensures everything is organized in specific compartments and padded for protection. It’s the go-to option for serious or professional photographers who need to bring an extensive setup to shoots.
-
20L is better for casual photography with minimal gear: On the other hand, a 20L is perfect for more casual photographers who only need the essentials. You can fit a single camera body, one or two lenses, and basic accessories. It’s lighter, making it easier to carry around when you’re doing street photography or short hikes.
3. Travel:
-
Use 30L for weekend getaways or multi-day trips: For travel, a 30L backpack works wonders for short trips where you need to pack several changes of clothes, toiletries, and electronics. It offers enough capacity for weekend trips or even as a carry-on for flights, without needing additional luggage.
-
20L is perfect as a daypack or personal item for flights: A 20L backpack, on the other hand, is excellent as a daypack for sightseeing or as a personal item that fits easily under an airplane seat. It’s big enough for essentials like a water bottle, a sweater, a book, and small gadgets, but compact enough to keep you light on your feet during your travels.
