How Big Is a 30 Liter Backpack

When it comes to dimension and measurement, the first thing comes to our mind is Mathematics. We are not that good at it. We guess you’re also not here a scientific lecture. So, it’s not going to be a harsh conversation about measurement and dimensions, but we’ll tell you everything in detail. Before that, we have a guideline for you which will help you to get a perfect backpack.

Now before getting a backpack of 30L or more than that you’ve to consider some points. Which are-

  • Torso length: After knowing your torso length, always try to get a backpack which is equal to your torso or lesser than it. Don’t get a backpack which is bigger than your torso size, and it’s very uncomfortable.
  • Tour length: Always consider it first. If you’re going for a month, and you have a lot to carry, then you have to get something bigger, but if you’re going for a day only then, you don’t need a big backpack. So, always think about how many days you are going to stay then purchase according to it.

Mostly, a 30L backpack has a length of around 48-53 cm and width of 25-30 cm. According to us, it can carry around 3 to 4 pounds smoothly. These backpacks are quite spacious too because in depth it has about 27-30 cm space. So, you can quickly go on a trip of a few days with it.

As the dimension has been explained. Let’s talk about the size of it. We don’t think that we have to talk about it. Just check the fun fact. The size of an ideal 30L backpack is up to 1800 cubic inches. So, it isn’t small at all. We hope, we didn’t bore you with the measurement.

What Fits In a 30L Backpack?

Forgiving you a proper knowledge regarding this section, we think we should share a story with you. It’s a story of our college friend Eric who travelled to India for six months with only a 30L backpack.

According to him, he was carrying a backpack which is Osprey Pack’s backpack. He found two things helpful about the backpacks which are-

  1. Its hip strap (which makes it comfortable while hiking too)
  2. The bag’s opening and closing system. It opens like a suitcase, so you don’t have to feel uncomfortable every time you open it.

Now, let’s see what he carried on it:

  • T-shirts: 8 T-shirts which were sporty, quick-drying and odor resistant. Three t-shirts were the full sleeve and made for winter or cold places like Manali and Darjeeling.
  • Pants: He took three jeans pants, two chinos, three shorts and one jogger for a six-month tour.
  • Shirt: He made four shirts in it.
  • Jacket: For cold places, he carried one leather jacket and one heavy hoodie with him.
  • Shoes: Two running shoes and one woodland boot for hiking and a pair of the flip-flop.
  • Accessories: He also carried two watches (in boxes), two sunglasses (in boxes), six underwear and four pairs of socks.
  • Perfume and other toiletries: Two bottles of perfume, soap, trimmer and a 350 ML shampoo.
  • One MacBook Pro with charger
  • One iPad mini with charger
  • One iPhone 7s matt black with charger
  • One headphone
  • One Nikon D5300
  • Towel
  • Two water bottles
  • Pen and dairy
  • One backpack cover: For protecting the bag from rain and dust.

So, it was his small list of items he carried on a 30L backpack comfortably for six months. As Eric said, the small backpack made his journey too easy. So we hope now you can assume how much you can carry on it. Also, let us know in the comment box if you have any experience like this.
