Most 13-gallon kitchen trash cans measure roughly 24–28 inches tall and 12–19 inches wide, with depth around 10–16 inches, though no single standard exists.
Squeeze a 13-gallon can into a tight cabinet gap and the number on the box won’t save you — “13 gallon” describes volume, not footprint, so two cans with the same capacity can differ by several inches in every direction. That’s why the dimensions, not the gallon rating, decide whether a can fits your space, your bags, and your lid clearance.
What Do The Numbers On A 13 Gallon Can Actually Mean?
Thirteen gallons is a capacity figure, and in the U.S. it’s the de facto standard kitchen size — frequently sold as 50 liters or 13.2 gallons rather than exactly 13.0. Manufacturers use that number to signal indoor kitchen use, not to promise a fixed shape. Retailers commonly describe these cans as suited to kitchens, offices, pantries, and copy rooms.
Because the rating is volume, exterior measurements swing widely. A can can be tall and narrow, short and wide, or square, and all three still hold 13 gallons. The practical takeaway: ignore the gallon label when measuring a space and go straight to the product’s listed height, width, and depth.
How Big Is a 13 Gallon Trash Can In Real Measurements?
Real listings show the spread clearly. The IKEA KNÖCKLA step can is listed at 24 1/2″ high, 19″ wide, and 11 3/4″ deep. McMaster lists a 13-gallon rectangle at 16 1/2″ wide by 11 1/2″ deep by 26 1/2″ high, and a square version at 13″ x 13″ x 29″. A Target Glad listing gives overall dimensions of 25″ H x 18″ W x 14.7″ D. Round cans get described by diameter instead of width and depth, which changes how you compare them against a rectangular space.
| Model / Source | Listed Dimensions | Shape |
|---|---|---|
| IKEA KNÖCKLA step can | 24 1/2″ H x 19″ W x 11 3/4″ D | Step, rectangular |
| McMaster 13-gal rectangle | 26 1/2″ H x 16 1/2″ W x 11 1/2″ D | Rectangular |
| McMaster 13-gal square | 29″ H x 13″ W x 13″ D | Square |
| Target Glad kitchen can | 25″ H x 18″ W x 14.7″ D | Step, with bag rings |
| Typical round 13-gal | Described by diameter, often ~14–16″ | Round |
Why Two 13 Gallon Cans Fit Very Differently
Lid design, pedal mechanism, and inner-bucket shape all add inches outside the gallon figure. A step can with a wide pedal housing needs more floor clearance than a simple open-top bin of the same capacity, and a square can often tucks into a corner where a round one wastes space. That’s the misconception worth correcting: matching the gallon number does not guarantee matching the fit.
Bag compatibility follows the same logic. Liner size depends on the can’s actual interior dimensions and its retention system, not the gallon rating alone. Some models include bag rings, clips, or a removable inner bucket that hold the liner in place, and those features change which bag size works. A can sold as 13 gallons can take a standard kitchen liner in one model and need a larger one in another. If you’re specifically working with a narrow footprint, a tested roundup of 13 gallon slim trash can picks narrows the field fast.
One more gating factor: several listings state indoor use only and advise against hot liquids, corrosive chemicals, and sharp objects, which matters if you were eyeing a garage or workshop spot.
How To Measure Before You Buy
Measure the opening, not just the floor space. Grab a tape and check three things in the spot where the can will live.
- Clearance height: from the floor to the underside of any counter or shelf, since lids and pedals add height.
- Cabinet or wall gap: the true width, leaving room for the pedal and for pulling the can out.
- Door swing and depth: enough depth that the lid opens and the can still closes behind a cabinet door.
Then compare those numbers against the product’s listed exterior dimensions on the retailer or manufacturer page — McMaster publishes exact figures for its 13-gallon trash cans by shape, which makes side-by-side comparison honest.
FAQs
Is 13 gallons a standard kitchen trash can size?
Yes. In the U.S., 13 gallons is the common default for indoor kitchen cans, and many are sold using the metric equivalent of 50 liters or 13.2 gallons. It isn’t a legal standard, just the capacity most manufacturers build around when aiming at kitchen use.
Will a 13 gallon can fit under a standard kitchen counter?
Often, but not always. Counter overhangs and shelf heights vary, and a 26–29 inch tall can with a lid or pedal may not clear a low cabinet. Measure the clearance height first, then check the listed exterior height rather than assuming the gallon rating guarantees a fit.
What size trash bag does a 13 gallon can need?
It depends on the can’s actual interior dimensions and its retention system. Bag rings, clips, or an inner bucket change which liner fits, so check the manufacturer’s recommended bag size for that specific model instead of buying by the gallon number alone.
