How are Backpacks Measured

Backpacking and hiking can be long trips, so comfort is always essential. This comfort can be achieved by getting a backpack that fits you right and has the proper adjustments made.

Prior to buying a pack, you should measure your body and determine a size that is appropriate for you. How are backpacks measured? This article will further discuss all the essentials you need to know about correct backpack sizing.

Measuring torso length for a backpack

In order to do this, you have to get a measuring tape and assistance from another individual. Ask the other person to measure you, starting from the most noticeable bump on your neck to a spot between the hip bones. To determine this point, place your palms on the hips with the index fingers placed across the hip bones’ crests.

Let the thumbs stay horizontal and pointed straight through the hips toward the spine. The other person can then measure down to that spot between the thumbs. The measurement from this is the overall length of your torso which you need for the perfect size pack.

Find the right carrying capacity

All backpack manufacturers assign pack sizes by way of cubic inches, inches or both. The perfect pack size differs with every individual since this will go by means of their packing habits. Hikers and backpackers who often travel light are capable of fitting a number of days’ worth of equipment and items into what would be a bigger daypack.

Casual hikers may not have that much of an idea or the budget for smaller, lightweight and costly gear. This typically means a bigger backpack in order to fully contain all gear from the small to more sizable items.

If you have doubts, you can place your standard hiking and backpacking items in a few stuff sacks or bags to make things more manageable. Go to your nearest gear shop and test some models.

Multi-day backpack
