Choosing a backpack that fits your body and meets your needs online may not be as easy as you think. Backpack models come in many sizes, styles, and designs that can confuse many people. Today, May Hop Phat will guide you on how to choose the best product when you shop for backpacks online, ensuring the right backpack size and proper purpose when shopping online.
Backpack Size and Measurements for Adults
When buying backpacks online, you should measure your torso first, especially if you need a bag for hiking, outdoor exploration, or business trips. Your backpack needs to be comfortable and easy to carry on your back. Here’s how to measure backpack size starting with your torso measurements:
- You need a flexible measuring tape
- It will be helpful if friends or family members help you with this task; you need to measure your back length and waist width

- After you take these measurements, record the specifications and apply them to view backpack types to see if they fit your body. Remember to look for size descriptions when buying online. The size and online appearance of backpacks are quite difficult to visualize, so you need to be careful.
- Cross-reference your body measurements with the backpack size you want to buy. Make sure the pack you choose meets your intended purpose.

Consider Backpack Size Parameters
- Under 30L – in this category, you’ll find school backpacks, work bags, or city day packs, etc.
- 30 to 50L – these backpacks are the best choice for travelers who want to spend a weekend elsewhere or for freelancers/entrepreneurs carrying lots of gear for their work/business
- 50 to 70L – these are multi-day backpacks, used for city vacations or short trips (3 to 5 days), hiking and camping

- Over 70L – such bags are perfect for extended trips (more than five days) for longer vacations abroad. Make sure that if you want to travel light and only carry one large backpack for the entire vacation, the size and capacity of your backpack lines must comply with carry-on luggage standards on airplanes applied by airlines.
