The most common 13-gallon trash bag size is roughly 24 inches wide by 27 inches tall, designed to fit standard 10- to 13-gallon kitchen cans.
If you’ve struggled with a sagging liner or bunched-up overhang, you know that a 13-gallon rating doesn’t guarantee a perfect fit. “13 gallons” refers to volume capacity, not a single universal dimension. Published sizes vary by brand and product line, so matching the bag’s width and height to your bin is what separates a clean fit from a constant wrestling match.
The Standard Dimensions: What To Expect On The Box
For most standard 10- to 13-gallon kitchen trash cans, the bag you’ll reach for measures about 24 inches wide by 27 inches tall. Hefty’s own guidance points to this as the go-to size for typical tall kitchen bins, which they describe as roughly 24 to 28 inches high and 12 to 16 inches wide. Published dimensions aren’t identical across brands. Here are some real examples from current product listings:
- Hefty Strong Kitchen Trash Bags: 23 3/4 in x 27 in
- Hefty Ultra Strong Kitchen Trash Bags: 23 3/4 in x 24 7/8 in
- Amazon Basics Tall Kitchen Trash Bags: 24 in x 27 3/8 in
- Plasticplace Extra Tall (SKU D13122WH): 24 in x 31 in
The variance isn’t a mistake—it’s a feature. Shorter bags (around 24 7/8 inches) suit lower-profile bins or under-sink cans, while extra-tall versions (like Plasticplace’s 31-inch option) exist for taller receptacles. Glad notes that most standard bags fit under-sink or freestanding kitchen bins comfortably.
Why “13 Gallons” Doesn’t Tell You The Whole Story
The gallon rating is a volume class, not a blueprint. A bag marketed as 13 gallons must hold roughly that much—about 49 liters, or 52 quarts per Glad’s conversion—but how that volume is distributed between width and height is up to the manufacturer. Beyond dimensions, material thickness matters more than most people realize. The bags above range from 0.9 mil (Amazon Basics) to 1.2 mil (Plasticplace extra-tall), affecting both puncture resistance and how neatly the bag clings to the can’s walls. A thinner bag is fine for lightweight trash, while a 1.2-mil option handles heavier loads. Also note these are kitchen or tall-kitchen bags, not general-purpose lawn or contractor bags—using them for yard waste or construction debris is a recipe for a torn liner.
How To Check If A Bag Will Fit Your Specific Can
Since published dimensions vary, measure your bin before you buy:
- Measure the can’s height from floor to top rim. A 27-inch-tall bag suits a standard 24- to 28-inch-tall kitchen can, leaving good overhang for tying off.
- Measure the can’s opening width at its widest point. The bag’s flat width should be close to or slightly larger than this so it drapes over the rim without stretching taut.
- Check the rim overhang. You want 2 to 4 inches of slack on each side to fold over the lip for a secure hold.
If your can falls outside the typical range, look for “extra tall” variants (like 31-inch or even 33-inch options) instead of forcing a standard-height bag. A bag that’s too short slips into the can; one that’s too tall bunches up. For safety, Wayfair’s trash-can listings recommend avoiding hot liquids, corrosive chemicals, or sharp objects. A bag’s thickness doesn’t make it immune to punctures, so double-bag or pre-wrap anything sharp.

The One Measurement That Matters Most
If you only remember one number, make it the height. Widths across brands cluster tightly around 24 inches, suiting most standard openings. Height is where divergence happens—spanning from roughly 24 7/8 inches up to 33 inches—and it determines whether the bag stays put or slides down. For a standard 10- to 13-gallon kitchen can, a bag around 24 by 27 inches is the safe default. For taller or oddly shaped bins, compare your can’s height to the printed dimensions and reach for an extra-tall version if in doubt. Always check the mil rating: it’s the only number telling you how much abuse the bag can take before giving out.
FAQs
Do all 13-gallon trash bags fit the same cans?
No. The 13-gallon rating refers to volume capacity, not a universal fit. Published dimensions vary by brand, from roughly 23 3/4 x 24 7/8 inches up to 24 x 31 inches or taller. Compare the bag’s width and height against your can’s opening and height to ensure it drapes properly.
What is the standard height of a kitchen trash can?
Hefty describes a standard tall kitchen trash can as roughly 24 to 28 inches high and 12 to 16 inches wide. A 13-gallon bag measuring about 24 inches wide by 27 inches tall is the common match, providing enough overhang to tie off securely.
How many quarts or liters are in a 13-gallon bag?
A 13 U.S. gallon bag holds about 49 liters, which Glad also describes as approximately 52 quarts. This is the volume capacity at full fill, though most users tie off well before that to avoid overfilling.
