Frequently Asked Questions
A. The capacity, or the volume for each 80″ linear bag is different, because the suitcase is not the same.
For instance, a 80″ linear golf bag will not have the same capacity as a 80″ suitcase or backpack.
Let’s do some math:
let’s assume you have a bag with these dimensions 75″+ 3″ + 2″ = 80 inches linear.
If you want to know how big the suitcase is, just multiply the dimensions and you will get the capacity in cubic inches, then convert it to litter.
75″x 3″ x 2″ = 450 cubic inches which is about 7.40 litters.
Let’s apply this this for a 62 inches suitcase.
29.5” + 20.5” + 11.75” = 62 inches
29.5” x 20.5” x 11.75” = 7105.9 cubic inches, about 116.5 liters.

If this is your first time Computing the linear inches for your suitcase, I think that you get the idea on how to do it.
Most airlines use the linear rule for checked baggage, while only few of them apply it for carry-on baggage.
