How Big Is a 13 Gallon Trash Can: Dimensions and Size Guide?

A 13 gallon trash can typically measures about 24–26 inches tall, 15–18 inches wide, and 12–15 inches deep, though exact dimensions vary by brand and shape.

Two bins can both carry a 13-gallon label and still differ by three inches in width — enough to decide whether one slides under your counter and the other sits in the hallway. The gallon number tells you capacity, not footprint, and that gap trips up more shoppers than any other detail. Below are the real measurements from current US product listings, the shapes that break the “standard” mold, and the clearance checks that matter before you buy.

What Are the Typical Dimensions of a 13 Gallon Trash Can?

Most 13 gallon kitchen cans land inside a predictable range, but every shape bends it differently. Rectangular and slim models usually run 24–26 inches tall, 15–18 inches wide, and 12–15 inches deep. Round versions trade width for diameter, often sitting about 24–26 inches tall with roughly a 16-inch opening across.

Real listings show the spread clearly. IKEA’s KNÖCKLA step trash can lists 24 1/2 inches high, 19 inches wide, and 11 3/4 inches deep — wider and shallower than the typical range. McMaster-Carr carries a 13-gallon rectangle at 16 1/2 in W x 11 1/2 in D x 26 1/2 in H, another rectangle at 18 in W x 11 1/2 in D x 28 3/8 in H, and a square model at 13 in W x 13 in D x 29 in H. That last one is nearly 29 inches tall — well past the “typical” ceiling.

Will a 13 Gallon Can Fit Under Your Sink or Counter?

Fit is not guaranteed just because a can is 13 gallons. Cabinet openings, sink plumbing, and door hinges all eat into the usable space, and a can that looks right on the product page can still bump the drain pipe or block the door from closing.

The fix is simple: measure your opening before you shop, using the exact height, width, and depth of the bin you’re considering — not the gallon rating. Then add clearance for anything that opens upward. Step-on and lid-lift models need vertical room for the lid to swing fully, and most retailers list only the closed overall dimensions, not the open-clearance height. A step can that lists 26 inches tall might need closer to 30 inches of open space to function without scraping.

Do All 13 Gallon Trash Cans Use the Same Bags?

Most 13 gallon cans are built around standard tall kitchen bags, but bag fit follows the can’s shape, not just its capacity. A slim rectangular bin can take a standard tall bag cleanly, while a round or square model may leave slack or pull tight at the rim depending on its width and depth.

The reliable move is to match the bag to the can’s rim circumference and depth rather than to the gallon label alone. A 13-gallon square at 13 inches wide takes a different bag drape than an 18-inch-wide rectangle, even though both hold the same volume. When a product page lists only capacity, check the listed width and depth to judge how a tall kitchen bag will sit.

Capacity figures are also a rough guide, not a precise measurement. Manufacturers list nominal gallon ratings, and actual usable volume depends on liner thickness, how full you fill it, and whether the lid occupies interior space when closed.
