A 13-gallon kitchen trash can is the standard US tall-kitchen size, typically about 24–26 inches tall and 15–16 inches wide in rectangular models, or 15–17 inches across in round ones.
The “13 gallon” label tells you bag capacity, not exterior dimensions — which is why two cans with the same sticker can differ by two inches in height. Someone replacing a can that slid perfectly under the counter has to measure, because the number on the box won’t do it for them.
This guide breaks down realistic dimensions by shape, explains the bag-fit math behind that 13-gallon label, and flags the lid styles that quietly add height.
How Big Is a 13-Gallon Kitchen Trash Can in Real Dimensions?
Most rectangular 13-gallon tall kitchen cans land at roughly 24–26 inches high, 15–16 inches wide, and 12–13 inches deep. Round cans run taller and narrower, usually 24–28 inches high with a 15–17 inch diameter.
Real listings confirm the spread. One 13-gallon kitchen can is published at 17 1/4 inches long, 13 1/2 inches wide, and 27 1/4 inches high. Another 13-gallon model is listed at 22.73 inches high, 15.84 inches wide, and 13.47 inches deep — nearly five inches shorter than the first.
That variation isn’t a labeling error. Manufacturers design around different footprints: slim cans that tuck beside a cabinet, wider cans built for a corner, and everything between.
How Do You Know a 13-Gallon Bag Will Fit Your Can?
A 13-gallon bag is built for a standard tall kitchen can, but the bag’s own dimensions decide how neatly it drapes. Hefty lists 13-gallon kitchen bags at sizes such as 23 3/4 x 27 inches and 23 3/4 x 24 7/8 inches, both sized for standard tall kitchen cans.
Bag capacity and can exterior size are two different numbers. A 13-gallon bag can fit several can shapes, but the rim overhang changes with each one — a deep rectangular can pulls the bag tighter at the corners than a round can does.
- Open-top cans hide almost nothing, so a slightly short bag shows.
- Swing-top and step-on lids clamp the bag at the rim, so overhang matters less.
- Lid-closed models need the bag to clear the inner liner without bunching.
One practical shortcut: check the bag’s listed width against your can’s outer width. If the bag is narrower than the rim, it will stretch and likely tear.
Will a 13-Gallon Can Fit Under Your Kitchen Sink or Cabinet?
Most 13-gallon cans are sized to fit under many kitchen sinks or beside cabinets, but the fit depends on lid style, shape, and the clearance your cabinet actually offers.
Height is the number that breaks the fit most often. An open-top can might clear a 26-inch cabinet opening while the same can with a step-on lid does not, because the lid mechanism adds height and a foot pedal adds depth.
Measure in this order before buying:
- Clearance height from floor to the underside of the counter or cabinet frame.
- Available width and depth, minus door hinges and any plumbing that intrudes.
- Whether you need the lid to open without hitting the cabinet above.
Sliding your pick under a low cabinet is the goal, and the buyers’ guide we keep updated — 13 gallon stainless steel trash can roundup — lists tested models with their exact dimensions and lid types, which is faster than guessing from a product photo.
Why Two 13-Gallon Cans Can Measure Differently
Brand, shape, and lid mechanism all shift the exterior size, even when every can holds 13 gallons of bag.
| Can Style | Typical Height | Typical Width or Diameter |
|---|---|---|
| Rectangular, open-top | 24–26 in. | 15–16 in. wide |
| Rectangular, step-on | 25–27 in. | 15–16 in. wide |
| Round, open-top | 24–28 in. | 15–17 in. diameter |
| Round, swing-top | 25–28 in. | 15–17 in. diameter |
| Slim rectangular | 26–28 in. | 12–14 in. wide |
| Compact rectangular | 22–24 in. | 15–16 in. wide |
| Example listing, model A | 27 1/4 in. | 13 1/2 in. wide |
| Example listing, model B | 22.73 in. | 15.84 in. wide |
The pattern worth remembering: the cans in the table hold the same bag volume while spanning more than four inches of height. Interior volume stays roughly constant because a narrower or shorter body is offset by a wider footprint or a taller profile.
Hefty’s sizing guidance makes the same point from the bag side — standard trash bag sizes and how to find the best bag for your bin — because the company publishes fit information by can type rather than by a single universal size.
Two mistakes show up again and again. Assuming every 13-gallon can shares one exterior size leads to a can that won’t clear the counter. Confusing bag capacity with can dimensions leads to bags that sag or split at the rim.
