A 13-gallon trash bag typically measures 23 to 24 inches wide by 27 to 31 inches tall, sized for a standard kitchen can.
That loose size range frustrates plenty of shoppers, because one brand’s 13-gallon bag may run several inches longer than another’s. The capacity figure describes volume, not dimensions, so the same 49.2 liters gets sold in flat widths and lengths that differ by manufacturer and model. The right pick for your bin comes down to measuring the can, not trusting the gallon label alone.
The Standard Width and Length Range
Most 13-gallon kitchen bags share a similar width, but the height varies more than you’d expect. Hefty’s own FAQ lists its kitchen bags at roughly 23 to 24 inches wide by 24 to 27 inches tall. Glad places the same capacity in the “kitchen/tall” category, meant for standard under-counter bins.
Common flat dimensions across the category include:
- 23¾ x 27 inches (a standard tall kitchen bag)
- 24 x 27 inches (another common model)
- 24 x 30 inches (an extra-tall variant)
- 24 x 31 inches (the extra-tall end of the range)
Plasticplace sells a 13-gallon white drawstring model listed at 24 x 31 inches and 1.2 mil thick, explicitly positioning it for taller kitchen cans. The same brand’s standard 27-inch bags serve ordinary bins.
How to Measure Your Trash Can for the Right Fit
Bag width should be roughly half the circumference of the can’s top rim. Wrap a tape measure around the opening, divide that number by two, and you have the flat width you need. Many standard 13-gallon cans measure about 46 to 48 inches around the rim, which lands right at a 23 to 24 inch bag.
For the height, measure from the bottom of the can interior to the top rim, then add 4 to 6 inches. That extra length provides overhang for tying off the bag and covering the rim while you fill it. A bag that reaches the rim exactly will tear when you try to lift a full load.
Why “13-Gallon” Doesn’t Mean One Fixed Size
The gallon rating tells you volume, so a 13-gallon bag always holds about 49.2 liters of waste. But manufacturers sell that same capacity in different heights to suit different can shapes, and thickness also varies from about 0.9 mil up to 1.2 mil in comparable listings. A thinner 13-gallon bag holds the same volume but offers less puncture resistance than a thicker one.
The extra-tall versions exist for deeper or harder-to-fit cans, which is why a 31-inch bag from Plasticplace is marketed separately from standard 27-inch kitchen bags. If your can has a lid, measure the interior depth with the lid open; if the bag is too tall, it folds over the rim and may block the lid from closing.
When a standard-height bag doesn’t quite cover your bin, check whether an extra-tall 13-gallon model from the same brand fits instead. For clear options, our tested roundup of the best 13 gallon clear trash bags compares the top choices by thickness and price.
Capacity also doesn’t equal safe load weight. A 13-gallon bag filled with dense scraps or heavy bottles can exceed what its material handles, so match the bag to the contents, not just the can size.
FAQs
Will any 13-gallon bag fit any 13-gallon can?
No. While most 13-gallon bags share a similar width around 23 to 24 inches, the height varies from about 24 to 31 inches across brands and models. A standard 27-inch bag may not reach the rim of a taller can, while an extra-tall 31-inch bag may overflow a short bin and block its lid.
How do I know if my trash can needs an extra-tall bag?
Measure from the bottom of the can to the top rim, then add 4 to 6 inches for overhang. If that total exceeds 27 inches, pick a bag labeled extra-tall or one listed at 30 to 31 inches in length. Brands like Plasticplace sell these longer models specifically for deeper kitchen cans.
Is a thicker 13-gallon bag always better?
Thicker bags, measured in mils, resist punctures better but aren’t necessary for light, dry kitchen waste. Listings range from about 0.9 mil to 1.2 mil in the 13-gallon category. Choose a heavier gauge for sharp recycling or dense trash, and a lighter one for routine food scraps to save money.
