# Trash Bag Sizes (Illustrated Charts)

I recently ran out of the smaller white trash bags that I normally use in the trash can in my kitchen so I used the larger green bags that I had on hand. This seemed fine until I realized just how large that trash bag really was and had filled it to the point in which it was almost too full to pull out of the smaller trash can. I wondered what size of trash bag would actually be the appropriate size for the trash can that I have.

If this has happened to you or you own a business in which you have very large trash cans and are looking for the appropriate size and thickness of the type of bags you want to use, this article is for you, and me since I am still trying to figure it out.

## What Size of Trash Bag Do You Need?

Here are two easy steps to determine what size of trash bag you need to use:

The first method to determine the appropriate trash bag size that you need is to use a handy dandy calculator method. There are many calculators on the internet that you can use to calculate the size of trash bag you will want to use. You simply will need to input the width, height, and diameter of the garbage can.

### Square or Rectangular Trash Cans

For square or rectangle trash cans you will take the perimeter which is the sum of all of the sides of you garbage can then divide by the number two. This will provide you with the width of your can. You then need to measure the height of your trash can before adding four inches to allot for the overhang of the trash bag once it is in the can. You will also need to add whatever the number is that you come up with that is equal to half the diameter that you already measured. This will ensure that the trash bag covers the bottom of your can properly without effecting the rest of the bag size.

### Round Trash Cans

First you will take the diameter , which is the width of your trash can , and multiply that number by 3.14. You will then divide that number by two which will give you the width of your trash bag. He will then measure the height have your trash can then add 4 inches for the overhang as well as half of the diameter for the bottom part of the can.
