How Big Is a 50L Trash Can? | Size and Fit Guide

A 50L trash can holds 13.2 US gallons, but its physical size varies widely—most measure roughly 24–26 inches tall and 14–19 inches wide.

For the full breakdown, see our best 50L Trash Can guide.

The short answer to how big is a 50L trash can depends on the model’s shape. While the capacity is standardized at 50 liters, the footprint changes with design. A typical rectangular soft-close can runs about 16.7 x 14.7 x 25.9 inches, while a slim motion-sensor version may measure just 15.7 x 10.7 x 24.4 inches. That difference matters when you’re fitting a bin under a counter or into a tight corner. Measuring your space first prevents the frustration of a can that doesn’t fit where you planned.

What Do 50L Dimensions Look Like In Practice?

Because the label refers to capacity and not a standard footprint, two 50L cans can look dramatically different side by side. Retailer listings for several popular models show the range:

• Rectangular soft-close model: 16.7 x 14.7 x 25.9 inches
• Another step model: 14.8 x 25.8 x 13.8 inches
• Semi-round plastic step can: 26.2 x 18.7 x 14.4 inches
• Wheeled stainless steel can: 25.7 x 19.8 x 12.8 inches
• Assembled black stainless step can: 25.6 x 16.9 x 14.5 inches
• Slim motion-sensor can: 24.4 x 15.7 x 10.7 inches

Width and depth swing the most between designs, so the exact model’s dimensions beat any general guess. Always check the specific listing rather than assuming a 50L label means a uniform size.

Will a 50L Can Fit In Your Kitchen?

The best way to check fit is to measure the base footprint where the bin will sit, then measure vertical clearance to the lowest obstruction above—accounting for open-lid height if you’re considering a step or sensor model.

For typical household use, iTouchless’s size guide suggests 10–13 gallons (38–50L) suits 1–2 people or a small kitchen, while 13–16 gallons (50–60L) is the most popular range for 3–4 person households. When measuring, leave 1–2 inches of breathing room for hinges and lid swing so the can opens fully without scraping nearby walls or cabinets.

Sensor and Step Cans Need Extra Headroom

A hidden gotcha with 50L cans is the difference between closed and open height. One step-pedal model measures 25.9 inches closed but 36.8 inches with the lid lifted. That’s over a foot of extra clearance needed above the can.

Sensor models that open automatically have the same issue. Measure the lid-open height, not just the closed height, to avoid a lid that can’t fully deploy under a low cabinet. The trash can size guide from iTouchless recommends accounting for this swing space when placing your bin.

Does Bag Size Match Can Capacity?

Trash bag fit depends on the can’s shape and inner bucket dimensions, not just the liter rating. Some 50L models include removable inner buckets, while others have specific bag compatibility notes in their listings.

Since retailer listings sometimes show inconsistent measurement formats, rely on the specific model’s dimensions and bag guidance rather than assuming a standard 50L bag fits every 50L can.
