What Size Trash Bag Do I Need? All You Need To Know

22 min read

To make room in my kitchen trash can for the smaller, white trash bags that I usually use, I used some larger, green bags that I had on hand. When I discovered how big the trash bag truly was and how much I had put in it, I almost couldn’t get it out of the smaller garbage container. I wondered what size garbage bag would be appropriate for the trash can I now have in my house.

As a result, if you’ve ever found yourself in this situation or own a business with enormous trash cans, this essay is for you — and me, since I’m still trying to figure it out myself.


What Size of Trash Bag Do You Need?

Here are two simple procedures to help you select the proper garbage bag size:

To begin, you can use a simple calculator to figure out how big of a garbage bag you’ll need. To figure out what size garbage bag to use, there are a plethora of online calculators available. The garbage can’s dimensions are as simple as its width, height, and diameter.

Square or Rectangular Trash Cans

To find the circumference of a square or rectangle trash can, add up the sides of the container and divide by two. This will give you the can’s width. If your garbage can is taller than four inches, you need to add four inches to account for the trash bag’s overhang after it is in the container. Additionally, you’ll need to include the value you arrive at after dividing your original measurement by half. This will ensure that the trash bag covers the bottom of your garbage can without affecting the remainder of the bag’s dimensions.

Round Trash Cans

To begin, multiply the diameter (the width of your garbage can) by 3.14 to get the final result. The width of your trash bag will be determined by dividing the number by two. Afterwards, he’ll take the garbage can’s height and add 4 inches for an overhang and half its diameter for the bottom portion of the can.

Once you’ve determined your right bag size, you’ll be able to shop with confidence. Listed below are our garbage bag size charts, showing the various bag sizes, along with the most appropriate applications and rationales for each.

What Size Trash Can Is Right For Your Home & Kitchen?

How much consideration did you give to your garbage can selection? If you’re like the vast majority of people, you probably didn’t give it much thought. It’s amazing that so few people do their homework before buying a vacuum cleaner, given how crucial it is to keep your house tidy. The size of your garbage can is a decision you should give particular consideration to.

Size does matter when it comes to trash cans. You don’t want to waste space in a room by purchasing a garbage can that is too large. If a trash can is overflowing because it is too tiny, it will need to be emptied frequently. Make your garbage can as “just right” as possible, following in the footsteps of Goldilocks.

In order to figure out how many garbage cans you’ll need, you’ll have to do some math. There are a lot of variables to take into account, but it’s a problem that needs to be solved. Trash cans come in a variety of sizes, so it’s important to pick one that fits your needs.

Here are five things to keep in mind while purchasing garbage cans for your home.

Things to Consider When Selecting Trash Can Size for Your Home & Kitchen

1. What Room Is It For?

The kitchen is where most people keep their largest trash can because that’s where the majority of their waste is generated. As a result of the tiny space available and the low volume of waste generated in bathrooms, small trash cans are an almost certain requirement. These cans, which can be a bit larger, are typically found in other parts of the house such as the garage, the basement, or the office.

A bathroom trash can typically holds about 4 gallons, whereas a bedroom or office garbage can often holds 7–10 gallons, and a kitchen trash can holds around 16 gallons.

2. How Many People Live In Your Home?

The amount of waste you produce is directly proportional to the number of people that reside in your house. Two or three individuals sharing a house produce less trash than a family of six or more. The bigger the trash can you need, the more waste you produce.

A 7–10-gallon garbage can should suffice for most empty nesters and young couples. To prevent having to take out the garbage too frequently, a family of four should choose for a container with a capacity of 12–16 gallons. Those living in a large family or property with more than four occupants may choose to opt for a larger primary waste container of 20–30 gallons.

3. How Much Trash Do You Create?

Garbage generated by people who compost their food waste is far lower than garbage generated by people who throw their food waste in the usual trash. If you don’t have recycling picked up by your trash provider, you’re definitely producing a lot more waste than the average person. For people without curbside recycling, we strongly recommend finding a recycling center to drop off their recyclables.

If you compost and recycle, a 7–10 gallon trash can should suffice for the rest of your garbage. If you include food waste in your trash, you need increase the capacity of your bin from 8 to 12 gallons. You can use a 20–30 gallon trash can to dispose of food, recyclables, and trash at the same time.

4. How Much Space Do You Have?

A huge trash can takes up valuable floor space in a tiny kitchen and obstructs movement. Despite the fact that an under-the-sink trash can is useful for freeing up floor space, it restricts the size of your trash can. Before you buy a garbage can, think about where you want to put it and how much space you have.

There isn’t much place for a trash can in most under-sink cabinets because they are 30 inches tall. Determine how much space you have under your sink before you buy a garbage can. Trash cans with a capacity between 12 and 16 gallons are ideal for bigger kitchens, as they can be tucked away in a corner. There is no problem with room in your kitchen, therefore a 20-30 gallon trash can may fit in a pantry or kitchen island.

5. What Size Bag Do You Prefer?

If you have a bunch of old shopping bags lying around, you may want to use them as garbage bags rather of the regular ones. You’ll simply end up with more rubbish if the bag is smaller than your trash bin. Using a 30 gallon bag with a 10 gallon trash can will result in a greater amount of trash as well as a greater amount of mess.

Do not buy trash bags that don’t fit your garbage cans or on trash cans that don’t fit your preferred bag style. The correct garbage bag for any trash can may be found in our trash can liner guide.

6. What Size Kitchen Trash Can Be Right For Me?

The correct size kitchen trash can is determined by a variety of criteria, but the two most crucial are the amount of waste you expect to generate and the location of the trash can.

  • How much waste are you generating each day? In the kitchen, it’s simple to produce a ton of waste, so you’ll need a can that can withstand any problems and isn’t likely to leak, and you’ll also need a lid because you don’t want any scents to enter your home.
  • What’s going to happen to the trash can? You’ll want to make sure the can is the right size for where you intend to place it. In order to prevent odor, make sure it’s covered if it’s outside the sink area or if it goes underneath your sink.

Steps to Choose the Right Trash Bag

More trash bags than you require is a waste of money and time. You don’t want to use a garbage bag that’s either too small or too large for your needs. To address the question, “What size trash bag do I need?” here are some tips:

Step 1

Find out what kind of garbage bag you’ll be using. Choose a trash bag with a low or high density depending on your needs. You’ll most likely utilize low-density ones if you need to get rid of sharp things because they are more resistant to puncture and tear. Choose high-density garbage bags if you’ll be tossing regular rubbish in them.

Step 2

Check to see if the garbage bag will fit in the container you already have. “What size garbage bag do I need?” is a popular inquiry. Ideally, your garbage bin should have a three-inch overhang to accommodate the trash bags, but this is largely dependent on the size of your trash bin. Having less or more than the stated overhang measurement means you’ve got the wrong size. You can use the product specification chart to figure out what size trash bag you’ll need to buy. The capacity of your trash bin is also printed on it.

In general, the outer diameter of your garbage container can be used to estimate the width of your trash bag. Add three inches to the bag’s length to account for the bag’s overhang when calculating the container’s height.

Step 3

Determine the appropriate garbage bag thickness for your needs. Manufacturers use the term “gauge” to define the thickness of trash bags. To handle heavier rubbish, you’ll need a larger gauge.

Factors to Consider When Selecting Trash Can Size

Where Would You Be Using the Trash Bin?

The kitchen, bathroom, bedroom, and garage are the most popular locations for trash cans. The kitchen is where the most waste is generated, hence it has the largest bin. Bathroom trash bins are smaller because they have to fit in a tiny space and because there is very little garbage in restrooms. The garbage containers in the garage are a little too big to fit all of the debris on the floor.

How Big Is the Household?

Consider the amount of individuals that live in the residence while deciding on garbage can size. For every additional person, there is an increase in garbage production and the number of trash bags needed. “What size garbage bag do I need?” is a popular inquiry. The size of your family may also play a role.

How much actual trash is created?

It’s possible that the amount of rubbish you generate is higher than in other households because of the nature of your job or lifestyle. Having a compost pile for organic and food wastes will reduce the amount of rubbish that must be thrown in garbage cans.

How Much Space Do You Have?

Depending on the amount of space you have in your home, the size of your garbage cans can also vary. If you have a limited amount of floor space, you’ll need to keep your garbage can size in mind. Before acquiring a garbage can, you should take into account the size of your region.
