Understanding Luggage Bag Sizes & Capacities | ACE Blog

Thank you for visiting our store. This is Amy from Ace Official Online Store. Today, as the title suggests, I would like to address the question of bags that are big in size but have a small capacity.

First of all, there may be doubts about whether the stated capacity can actually fit in the bag. However, for our products, there is no doubt that the stated capacity can fit because we measure by actually putting pellets (resin particles) into the bag.

【Measurement Method】

For measuring the product itself, pellets are used.

・Small pellets (about 4mm in diameter) are used to minimize the gaps between particles.

・Pellets are put into a measuring container (a cubic container with a side length of 10cm, shown on the left in the image above) with a volume equivalent to 1 liter, and they are placed without any gaps in the bag of the finished product. This process is repeated multiple times, and the average is taken.

・Only the space that customers use for their specifications is measured.

 ※For products with pockets, the capacity of the pockets is also considered part of the overall capacity.

 ※The maintenance zipper provided for repair purposes is not considered a pocket and is not included in the measurement.

Now, let's see how this compares in practice.

Let's take a look at the Proteca Checker Frame suitcase as an example.

The stated capacity for the Proteca Checker Frame suitcase is 35 liters.

However, if we calculate the capacity based on the product's size, which is 53x37x25cm, the result is 49 liters. As you can see from the image, the height from the ground to the top of the handle when it's upright is 53cm. This calculation does not take into account the thickness of the body, protrusions, and the system handle that reduces the content volume.

That's why Ace Official Online Store wants to be honest with our customers and show the actual capacity that can be stored, instead of just theoretical calculations. We believe that this is important because there are no clear standards for displaying capacity in the bag industry.

We provide a cut-off capacity indication, which means that the indicated capacity is always possible to be stored in the bag. For example, even if the actual capacity is 4.9 liters, we would indicate it as 4 liters. This might result in a significant difference in the perceived capacity, even for bags with similar sizes.

So please rest assured that we measure the capacity by filling the bag with pellets.
