How Big Is a 13 Gallon Trash Can? Dimensions and Sizing Explained

A 13 gallon trash can is a capacity rating, not a fixed size — most kitchen models stand about 24 to 26 inches tall, 15 to 16 inches wide, and 12 to 13 inches deep.

Two bins that both hold 13 gallons can differ by several inches in footprint, and that gap is what decides whether a can slides under your counter or jams against the cabinet door. The “13 gallons” label only tells you how much the liner holds. The exterior is a separate number you have to check on each product page before buying.

Here is what actually varies, what the current models measure, and the mistakes that send people back to the store.

Why 13 Gallons Doesn’t Tell You the Size

Thirteen gallons is a volume rating for the inside of the bin, so it says nothing about the outside. A tall, narrow can and a short, wide one can both hit 13 gallons while occupying very different floor space.

The height range is the most predictable part. Most 13-gallon kitchen cans land in the low-to-mid 20-inch zone, which is why they pair well with standard counter heights and 30-inch base cabinets. Width and depth swing much more, because manufacturers trade one against the other to keep the same internal volume.

Shape drives it further. A round can reads one way on a tape measure, a rectangular step can another. Two 13-gallon bins side by side can look nothing alike and still be advertised with the same number.

Real Dimensions From Current 13 Gallon Models

Actual product listings show the spread clearly, and the three below cover the common shapes. Notice how much the width and depth move while the height stays close.

The pattern holds: heights cluster between roughly 22 and 26 inches, while depth ranges from under 12 inches to nearly 15. If your space is tight in one direction, check that specific measurement rather than trusting the gallon number. The IKEA KNÖCKLA, for example, is unusually shallow at 11 ¾ inches deep despite its 19-inch width. IKEA’s KNÖCKLA product page lists those exact figures.

Will a 13 Gallon Can Fit Under Your Counter?

Under-counter fit depends on cabinet height, width, and — the part people forget — plumbing clearance. A can that matches your cabinet opening on paper can still stop short because a sink drain or disposal sits in the way.

Measure the clear opening, not the cabinet’s outer size, and check height from the floor to the underside of the counter. One product listing explicitly flags its 13-gallon bin for indoor use only, which matters if you were picturing it on a patio.

Lid clearance quietly adds height too. A step can’s lid swings up and needs room above the rim, so a bin that fits with the lid closed may not open cleanly under a low shelf.

Liner fit is its own trap. Bag-ring systems and the recommended bag size differ by model even when the gallon rating matches, so check the product’s own liner guidance. If you are weighing a can for sorting recyclables instead of trash, our tested 13 gallon recycling bin roundup covers models built for that job.

Common Sizing Mistakes To Avoid

Most returns trace back to one of three mix-ups, and all three are easy to sidestep with a tape measure.

• Assuming every 13-gallon can has the same footprint. The table above shows widths from 12.63 to 19 inches on cans holding identical volume.
• Treating capacity as exterior size. The gallon number rates the inside; the outside is what has to fit your space.
• Measuring only height. Depth, lid swing, inner bucket size, and under-sink pipes all decide whether it actually works.

Measure your opening in all three directions, compare against the product’s listed dimensions, and confirm the shape works for where you plan to put it. The Sterilite’s footprint at Home Depot runs 24.75 inches tall, 12.63 wide, and 16.38 deep — a very different rectangle from the Glad’s 25 × 18 × 14.7. Same capacity, different corner of the kitchen.
