Why and How to measure Liters in Backpack?

First of all, it doesn’t seem very easy to measure any backpack size. And only one way to measure it is by its volume. The unit of volume is liter. That’s why for backpack capacity, always uses liters for their volume unit. The primary measurement is any backpack’s main compartment size. That means the introductory section size is the liters-wise size of any pack.

Another complicated part of this bag is how to measure. The measuring process is also quite interesting. Because we need the help of math for this, you can easily estimate your backpack with your free hand. You need to know about the bag’s depth, length, and width. After gathering all information, multiply it with each other. The value you get is called cubic value. When you divide this value by a million, you can easily find the size of the backpack.

Standard Dimension, weight

It is challenging to say the exact size and weight of any backpack. Because it depends on the design, features, materials, etc., we can assume a stander size that satisfies more 30L bags. Supposedly, the average length or height is 18.5 to 21 inches, and the average width is 9.5 to 12 inches. If you are a student, this backpack size is handy. You can carry a laptop, and some notebooks in this easily. And some of the bags have an extra comfy compartment for your computer.30L BackpackCheck Today’s Price

On the other hand, the weight is also variable for various backpacks. But most of the 30l backpack is 2 to 3 pounds in weight in general. If you want this bag size for your short Tour or any weekend plans, always look for a lighter one. Because it’ll be hard to carry a loaded bag, and if it’s heavier by its weight, that’ll make a fuss.

Materials, waterproof, and Budget

Material is the structure of any backpack. So it is essential to choose a material that is hard to rip and helps from getting wet on rainy days. But most of the time, brands use nylon, polyester, mixed ripstop, or recyclable fabrics. This fabric is most commonly used in any backpack because it makes any bag durable in any harsh environment. They are also suitable water-resistant .this materials are very light in weight, so they don’t add much weight to the shoulder, which is the first demand of every hiker and traveler. This size bag’s other most important part is its shoulder strap and back panel. These two things are always an important part. Most bags use high-quality soft foam with air ventilation fabrics, which comfort your back when carrying a heavy load. Many brands are using a flex vent system because of better air suspension. You also find separate laptop sleeves in most of these size bags. These sleeves are secured with soft padded. The funny part is it also adds extra weight to your backpack.

Most of the backpacks are water repellent or resistant. It is hard to make a bag waterproof with these fabrics. This process also raises the cost of any gear. These size bags are preferable for students most of the time, so Budget also matters. You can find a waterproof bag in the market quickly, but it’ll be expensive. It will be good for you if you buy a rain cover for the bag, that’s how it’ll be waterproof ideally. Now some backpacks came with an extra rain cover.

Number of Compartments

Most of the 30l backpack has one main compartment in common, and this is the main volume of any bag. Various organizing rooms, bottle sections, and laptops came with this kind of bag. The laptop sleeves are separate from the main compartment; others are attached. But both use a soft thick pad for safety. Nowadays, many brands connect a tablet section with this laptop one. There are many different subsections in the organizing section for your little item. One or two hydration sections are available in every 30L backpack. A bungee cord is linked up in the front part in some backpack models. This part enhances the design and gives you quick storage for your jacket, yoga mat, or towel.
