How Big Is a 13-Gallon Trash Can? | Size, Fit & Dimensions

A 13-gallon trash can stands roughly 24 to 26 inches tall and spans about 15 to 16 inches wide, though the exact dimensions vary by brand and shape.

Walk down any home-store aisle and you’ll see the same label everywhere: 13 gallons, the default kitchen size for U.S. households. That number, though, tells you capacity, not footprint. Two cans can both hold 13 gallons, and one might stand a foot taller than the other. Whether a 13-gallon trash can actually fits your space depends on its shape, its lid, and the specific brand—not the number on the box.

The Standard 13-Gallon Trash Can Size

Most retailers and buying guides treat a 13-gallon can as roughly 24 inches tall, 16 inches wide, and 13 inches deep. That’s a useful starting point, but it’s an average, not a promise.

Rectangular cans in this class usually run 23.6 to 28.2 inches tall, 12 to 16.35 inches wide, and 13 to 17.3 inches deep. Round cans swap width for diameter, typically landing around 24 to 28 inches tall with a 16 to 17-inch circle. Slim models trade that width for a narrower profile that squeezes into tight gaps between cabinets.

Real-world examples show the spread. IKEA’s KNÖCKLA step can, sold at 13 gallons, measures 24 ½ inches tall, 19 inches wide, and 11 ¾ inches deep. Sterilite’s TouchTop version of the same capacity is 24 ¾ inches tall with a 16 ⅜ by 12 ⅝-inch footprint. Same volume, noticeably different silhouettes.

Does a 13-Gallon Can Fit Under a Counter?

Standard kitchen counters leave about 34 to 36 inches of clearance, so most 13-gallon cans slide underneath without issue. The catch is the lid.

A swing-top or step-pedal lid needs vertical room to open. A can that fits by its footprint alone may jam against the underside of the counter the moment you press the pedal. Check the height with the lid completely open, not just closed, and compare that number to your actual under-counter clearance. Product pages usually list overall dimensions, which can differ from the usable opening height once a lid swings up.

Common Mistakes When Buying a 13-Gallon Can

• Assuming all 13-gallon cans are the same size. Capacity is a volume class, not a standardized cabinet size. Brand-specific exteriors vary by several inches in every direction.
• Confusing capacity with dimensions. A can can hold 13 gallons and still be much slimmer, taller, or wider than the “standard” estimate—check the listed exterior measurements, not just the gallon label.
• Ignoring lid clearance. A footprint that fits is useless if the lid can’t swing open under a cabinet.
• Grabbing the wrong bags. Most 13-gallon models pair with standard 13-gallon tall kitchen bags, but unusual shapes or extra-tall cans may need a different fit even at the same gallon rating. Confirm the bag type a model recommends before buying.

What 13 Gallons Actually Means

Thirteen gallons equals about 50 liters, and that capacity is the most popular kitchen trash can size in U.S. households. It’s the practical middle ground: big enough to avoid daily trips to the outdoor bin, small enough to tuck under most counters.

The 5.5-gallon to 10-gallon range usually covers bathrooms and offices, while 13 to 16 gallons is the common household kitchen band. If you’re comparing models side by side and one looks significantly larger than the other at the same gallon rating, trust your eyes—the exterior dimensions tell the real story.
