Can Liner Sizing Guide

What Size Liner do I Need for My Trash Can?


Using the guide below, find your waste receptacle to find the recommended liner size.


Commercial can liner sizes are expressed in two numbers e.g. 33" x 40". The first number is the size of the opening of the liner and the second number is the height of the liner. To find the correct size liner, first measure the can's circumference then measure its height.


Each container should have a gallon capacity, or size printed on it. Just match the picture in the PDF attachment to your receptacle and it will tell you which size trash bag you need.


Bag Width:

To calculate the proper width of the trash can liner for your container, simply divide the circumference of your container by 2.


Round Container Circumference:

Circumference = diameter multiplied by 3.14.


Square Container Circumference:

Circumference = sum of all four sides added together.


Bag length:

(round & square containers) add the height of the container, plus 4-5 inches for overhang.



Choose the Right Trash Can Liner for The Right Application

Linear Low Density Can Liner: Recommended for sharper objects under tougher transport conditions. Linear low density trash can liners have excellent resistance to punctures and tearing.

Puncture Resistance: Good

Tear Resistance: Better

Load Capacity: Good


High Density Trash Can Liner: Great for paper and non-sharp objects under moderate transportation conditions. Uses less plastic than linear low density can liners. High density plastic trash can liners have excellent resistance to puncture and high resistance to tearing.

Puncture Resistance: Better

Tear Resistance: Good

Load Capacity: Better


Understanding Gauge Thickness

Gauge is a term used to describe thickness. Film thickness is no longer the standard for judging plastic can liner strength. Advanced resins and additives have allowed manufacturers to produce thinner, lighter can liners that are stronger than thicker trash can liners made from lesser quality materials. Linear Low-Density Can Liners (LLD) are measured by mil thickness; High-Density Can Liners (HD) are measured by Micron thickness.


Mil: (one thousandth of an inch) one mil equals .001". Can liners range between .35 to 4.0 mils


Micron: 25.4 microns equals .001". 1,000 microns (M) is 1mm. Can liners range between 5 to 24 microns

Micron to Mil conversion:

5 microns - .19 mil

6 microns - .23 mil

7 microns - .27 mil

8 microns - .31 mil

9 microns - .35 mil

10 microns - .39 mil

11 microns - .43 mil

12 microns - .47 mil

13 microns - .51 mil

14 microns - .55 mil

15 microns - .59 mil

16 microns - .62 mil

17 microns - .66 mil

18 microns - .70 mil

19 microns - .74 mil

20 microns - .78 mil

21 microns - .82 mil

22 microns - .86 mil

23 microns - .90 mil

24 microns - .94 mil

25 microns - .98 mil

26 microns - 1.02 mil

27 microns - 1.06 mil

28 microns - 1.10 mil
